Ask Evan 240
The 1985-86 Honda Shadow VT1100C used two ignition control modules, OEM part numbers 30400-MG8-005 & 30420-MG8-005. I want to know if the 1985-86 VT700 used the same modules. The modules were made by Hitachi but they no longer make them and Honda does not have any more in stock. I have spoken with various parts houses and salvage yards across the nation with no luck. I would like to know if the VT700 modules could be used because I have come across someone that has one for sale very cheap. The price of the VT700 would be less than the cost of the OEM modules (each module has a msrp of more than $300). The VT700 would cost me $500. If the modules are the same, it would be a deal worth making. Any comments? Any idea if the modules are interchangable? All help would be much appreciated. Chief
Hi Chief –
The Ignition Control Module on the VT700 is part number 30400-MK3-721 (replaces 30400-MK3-004)
Doesn’t look like you have a match.
Keep your eyes on eBay – You’ll find one eventually. It could be pricey though.
Hi, Great Bikes you have!! I like your Yamahas the best. Do you sell them, or just keep them after you get them fix up? How big is your shop?
BIG ED XT&TT 600 FAN!!
I get a lot of shop questions. I’ve had lots of different work spaces over the years.
When I lived in a small apartment I worked out of here:
It was small and cozy, but I was able to get a lot done. I sealed it in with a tarp in the winter to try and keep it somewhat warm – but it didn’t work well.
Sometimes I have the bikes inside:
Then I upgraded to an excellent garage.
Man, I loved having that space. My landlord wasn’t thrilled though, hah!
When I’m on the road I work where-ever I can.
And there are lots of times I’ve worked out of storage units.
I pretty much just work where ever I can. I wish I had a great garage right now, but I don’t.
And to address your other question. No, I don’t keep them. I wish I could, but mostly I fix them up, ride them a while, then sell and buy something else.
Got this bike with 18k. Well taken care of but smashed headlight 12 years ago. In the process of locating light assembly and parts to get it running. The tank is a toaster but not original to the date 1971 so I want to get the original 6 gallon and paint it white. Any thoughts?
Hey Boxer – awesome bike! The /5’s are my favorite airheads by far. When I was cruising around on my R60/5 I always secretly wished it was an R75, however I did always like the super simple Bing carbs on the R60.
Your bike looks beautiful. I’m with you though – I prefer the 6 gallon touring tank to the toaster tanks. The tank will be hard to find, and expensive. There are many guys you prefer the toaster tanks and may be interested in swapping. The only two places you’re likely to find some tank options are on ebay and on the BMW motorcycle owners forumshttp://www.bmwmoa.org/. Your search will be long and difficult, so I wish you luck.
You are right that the perfect tank for your bike is a white 6 gallon. Personally, I would only want a tank with original paint, even if the paint was beat up. I love the look of a nice old worn original paint job.
How does the bike run? I notice you have the spark plug leads disconnected and the carb is being tinkered with.
Anyone know a good mechanic in Miami? My Honda is not getting oil on one side of the engine. Would appreciate any tip.
If your oil flow is impeded only in one area you likely have a clogged line. If the oil pump or related components were failing then you wouldn’t have oil anywhere on the top end. If you’re sure about this then you likely already had a failure, in which case you’ll need to tear down the top end and inspect. Otherwise you’ll need to do the same, sadly.
Need more advice on this KZ650 cafe project. Bike is pretty clean but I am having the engine plastic bead blasted anyhow just to even out the look of the aluminum. Till I am done this bike is going to be mostly engine anyhow so I want it to look good.
On my CB 900 I painted the engine black with high heat paint as it was mostly painted factory black in 82 anyhow. But with the KZ I am wondering what sort of clear coat can I put on that protects the freshly blasted aluminum from oxidation while handling the heat without trapping too much?
My CB has an external oil cooler so heat is not a big issue but I’ve heard both painted air cooled engines are not a good idea to it doesn’t matter?
I like the Duplicolor Engine Enamel products. I find they lay down much nicer than the Rustoleum and other spray equivalents.
I wouldn’t worry about spraying too many coats of paint on your engine. CB’s do not run especially hot and a few coats of paint has little effect. Many of the motors came painted and clear coated from the factory anyway.
Last year my son gave up on this bike and asked me if I wanted to give it a try. He could rarely get it running and could never keep it running for very long.
I have no experience with motorcycles but decided to accept the challenge.
I am in the process tearing it down, cleaning it up, assessing what needs to be done, and getting it running and keeping the cost down until then. In other words, little is being spent on cosmetics at this time until I see if I can get it working properly.
I’ve decided to keep a blog of my progress just for grins and to amuse my friends, but it occurs to me that perhaps if some folks who actually know motorcycles take a look at what I’m doing, perhaps some useful advice can be gleaned. So, just in case anyone is itnterested, and cares to see how I’m going about this I’ll include the URL and maybe I can get some free advice.
Great looking project! You’re really putting some elbow grease into it.
How did the pistons and cylinder walls look when you opened up the motor? Did you happen to do a compression check. At first glance everything looks to be in decent shape.
I’ll give your blog a read. Thanks for posting!
The cylinder walls looked pretty good I didn’t notice any scoring or discoloring. The tops of the pistons had some carbon build-up, as did the cylinder heads. Didn’t do a compression check before I opened everything up…mistake??
I’m looking for a shop to mic the pistons/cylinders and check valves before reassembling. I should do this right? Also waiting on a gasket set I ordered.
Also, I’m wondering about cleaning the pistons and cylinder heads…any particular type of solvent I should look for? How abraisive should I get? Anything I absolutely shouldn’t do?
Wow! What a fantastic looking bike. You did a truly great job on it.
How is she running? Just as sweet as she looks I presume.
please take a listen to the video in the link and tell me what you think about the noise that’s almost like a backfire. OK? Bad?
also, near the end of the video there is smoke that is coming from the area of teh prechamber. anything to worry about there? it’s hard to see.

Hey Iprete –
Sounds like there are a couple issues in the video. Number one – the bike is LOUD. You have no baffles. In my experience, you aren’t going to get any vintage air cooled bike to run well without baffles unless you put quite a bit of effort into jetting and tuning. If you are just looking for a bike to zip around town on I would actually recommend trying to get some real mufflers on there that provide some back pressure to the exhaust valves.
Two – Yes, sounds like you’re running only on one cylinder. This can be caused by all sorts of things. You definitely have a little exhaust backfiring. Pull your plugs after running, I bet one of them is wet. It’s either wet because:
A.) The cylinder is getting too much gas (stuck float, improper float height, way off throttle sync)
B.) There is no spark to burn the gas (bad spark plug, bad cap/wire, dead coil)
The bike is definitely looking great. Seems like you’re right on track. If you plan to keep it and ride a while I’d recommend a muffler that hasn’t been hollowed out. Even a cheap Dunstall replica will give you decent back pressure and help the motor idle smoothly.
Notes from a Reader:
Evanfell is 100% right. I have a Z750 twin which was doing the same thing. Gave the carbs a good clean through, changed mains to slightly bigger and baffled the loud exhausts. She runs sweet now. yours sounds like it’s definitely the carbs palying up
looking to turn my bike into a bobber really do not know how to go about it,do you think a shaft drive would turn out as a sweet bobber…this bike I hav had since new really do not want to let it go so really want a bobber and think it would make a nice one but never seen a shaft drive as a bobber if you know of any or have any pics would love to see them and any input you have would be greatly appreciated thanks bro looking forward to hearing from you Peace bro, Pete…
The quality of the finished project will be exactly as good as the effort and time you put into it. There have been tons of awesome shaft drive bikes built, the XS line is no exception.
I tend to like the bagged out XS1100’s myself, but I’ve always been an XS11 fan.
Hey I have an 82′ kz440 that i chopped into a bobber and i’m tryin to wire it the your diagram. this is my first bike that i am wiring. Your diagram is for a 4 cylinder and my obviously is a twin. maybe if you got a diagram for one you could email it to me. let me know!
The KZ440 is a great little bike. Should be a fun project for you! There isn’t much of a difference in wiring between a 2 and 4 cylinder bike, and if you go off ofhttp://cycles.evanfell.com/2010/03/simple-motorcycle-wiring-diagram-for-choppers-and-cafe-racers/ then you shouldn’t have any issues. The only difference is you have one coil instead of two.
Scored a mostly in tact 1981 XS400 earlier this week for a steal. Definitely a project but it looks like it’ll be back up and running (at very least) with not too too much work. Anybody played around with one of these before? I’m debating going street tracker or cafe on it. I mostly ride around New York City and up into the catskills/mountains. I’m looking to keep this on the cheap. Things I know I need are a clutch lever (ordered), a battery, tires, and almost 100% gonna need some cables and gaskets. I’m definitely doing a seat/bar swap as well.
Any advice on what you’ve all done before and had fun on? My other bike’s a 2001 buell blast with a bastardized cafe set up and it’s a ton of fun.
The XS400’s have great little motors, I’ve always enjoyed mine. I typically prefer the 1977 XS400 models because they are a more standard style rather than a cruiser like the later years. But they are good all around bikes regardless. I wouldn’t go ‘cafe’ with a cruiser if I was you, they never look quite right. Just clean it up, make sure it runs/rides nice, and enjoy it as is!
Notes from a Reader:
I own the bike as well. The common thing with the XS seems to be Cafe Racer. I can’t wait till I have money to make it worth something. The only thing I’ve had a chance to do is throw straight pipes on mine and do minor fixing up from accidents.
The only thing I have to say specific to the XS400 that I’ve noticed is the headlight is terrible weak if you ride at night.
I have a modified 26″ Bicycle which we STRETCHED 18 1/2″ are going to add 2cycle China Bike Motor 70cc to. :devil:
TO EXPLAIN WHAT WE HAVE DONE:
we lowered bike (top of seat is 20 1/2″ from street surface) because we are using 17″x3.50″ rear Motor Cycle rim, tire and 10G/36H spoke coupled to a Custom Bicycle hub. which has 6 speed free wheel gearing and disc brakes. the original BB or where pedal/chainwheel and crank were is now right side removable (2) chain wheels 42t attach by chain to rear wheel, 24t attached to new BB chain wheel 38t and crank which is 18 1/2″ forward from original location, to give leg room to pedal bike. Now on left side of bike on original BB axle is 18 or 22t free wheel to attach to drive gear on motor. We actually extended bike from seat post to front fork 18 1/2″ stetching out frame and then double walled all tubing. We are using a Honda M/C front fork (suspension) which actually let use use either 26″ or a 24″ disc brake bicycle rim and tire (Double walled rim) We were actual able to fabricate a bracket to mount caliper to and original caliper fork mounts….lined up perfect with rotor.
REASON FOR SOME OF THE ABOVE (OTHER THEN LOOKS :
What we have done is added freewheel to center BB to let motor sit still while pedaling and vise versa let the pedals sit still while under petrol power. (because of pedals it is considered a bicycle still and with specific additions is street legal with no license needed.
NOW THE PROBLEM:
When we extended frame we gave Head Tube more rakeactually just turned it over. Not wheel wants to dart here and there. (when you turn fork ground contact point varies) We had Nice 26″ x 1.38″ tire and rim. We switched to 24″ x 1.75″ and that seemed to improve handling, Why?
If we go to 1.96 width tire or 2″ or even 2.25″ will it continue to Improve? Is it because wider tire is more contact surface? With 26″ as we turned fork tire contact seemed to roll from center tread to off center. Could I even go to 26″x 2.25 or 2.50 and get same improvements? (would look more Radical )
Hey David – sorry for the delay – I’ve been out riding!!
Every bike, bicycle, motorcycle, etc will have a unique steering geometry and performance based on the rake, wheel size, fork length, and axle mounting position. The longer you stretch the front end of a bike the more the tires contact point with the ground will shift side to side when the handlebars are turned.
Ever notice that when you take a hard right corner on your motorcycle you actually turn the wheel to the left? Thats due to the offset, there’s not simple way around it. That’s also why, when you park your bike on the street you always turn the handlebars in, because the front tire will then be further to the outside of the bike’s axis allowing it to lean more firmly into the kickstand.
The slower you are traveling the more pronounced this effect will be.
If you want a more sharply steering and controllable bike, then bring your forks closer to vertical. A vertical fork is the only one which will not exhibit an offset in ground contact when the bars are turned.
You can also use a smaller tire, which again will reduce the side to side offset.
Keep me posted on your progress!
Hey. Bike me!
I have owned nearly every make and model of vintage Japanese motorcycle as well Europeans and more modern bikes. I do everything from simple fixes to full restorations. I also travel by motorcycle and race off-road. This is a blog about my bikes.
