I recently acquired a 1993 VFR750. Little rough, but good price and figured it'd be a nice project bike. I'll link the thread that the previous owner posted trying to figure it out, but basically he let it set for a couple years, and when he got back to it, the ugly starter clutch was problem arose. After he replaced it, it cranked over fine, but no spark. Since then the ICM and pulse gen coils have been replaced, and we have both been through all the troubleshooting in the manual, and still nothing.
Not sure if this is the right topic, but I bought new pulse gen coils and went to test them according to the manual, and apparently they test bad. I was hoping anyone with a running bike could take a minute and do me a favor by measuring the resistance on their 4 pin plug? Manual says to "measure the resistance between white/yellow-yellow and yellow-white/blue terminals." the resistance should be between 200-400 ohms, but both my old and new one are reading 300 on the first, and if im measuring right, no continuity on the second set. my problem is it appears that the second set is one wire from each coil, and there doesn't seem like there should be any continuity anyways. hopefully this made sense, and also should the coils be gapped from the pickups a specific amount?
I bought this VF500F earlier this year as a project bike and my second ever motorcycle. I have been working on making it look better and work as it did in the '80s(while modernizing where I can). I thought I was buying a 1985 VF500F, but have since found out from the MTO history documents that it is an '84. Its got 56 thousand km on it, but it runs and it was cheap. I have been told that one of the previous owners restored it using a few donor bikes and based on the frame paint and what not I'd say it has. I have been taking it apart and learning how it works so that I can fix up anything is out of date or falling apart. It has been fairly straight forward so far using guides and chatting with people on this forum, but I have a few questions and am looking for general advice. I've been thinking about the exhaust on this bike for awhile. The bike has some sort of upgraded 4-1 exhaust on it and I think I've identified it as the Hindle 4-1 pipe. It shows it's age though. There is rust pitting and an odd cloudy texture on the metal. How do I resurface the pipe? Also, the can that was on the end was a SuperTrap, but its kinda broken and I'd like something lower profile too. I have been considering leaving the end open as a straight pipe, except the end of the pipe is messed up and has an adapter bolted straight through it. To fix this I want to remove the end bit of the pipe and fab my own stainless side exit. Would this be viable? Will it mess with the tuning too much? I am aware of the carb jetting I'd need to do in order to make it work and I can do it. All that I've been reading from GAZ's topic about building his own pipe has put me off though. I'd also like to know what having this pipe means compared to stock. Besides the exhaust I am open to advice for things to fix. So far my list of things to do looks like this: Tires Repainted wheels Lights Speedometer Redone seat Chain and sprockets Wobbly clutch lever(How do I fix this?) Carb sync and clean Carb jetting Mirrors I am going to link an album of pictures here for the pipe. http://imgur.com/a/RmqqA P.S. - I am not keeping the original look of this bike, but I am a huge fan of the engineering behind the VFR series and I've wanted one of these since I first got into bikes. If anyone in Ontario needs red plastics or stock parts I can hook you up. This is an ultra-low budget D.I.Y. build, since I'm 18 and in school(before anyone suggests super sonic builders who can do it for me). Why is mine red?
