New here. Just picked up a VF500F. What it does: Start it up, ride around for about 5-10 minutes, and it starts to misfire on one cylinder. Shortly thereafter if you try to keep going / push it then it will stall out. I have to wait about 1-5 minutes, then it will restart and run fine again for another 5-10 minutes. The duration appears to be dependent on RPM. At about 4000rpm in sixth, I was going a little over 10 minutes between the misfiring. I did take it on the freeway and opened up the throttle, when it started misfiring it was smoking out of the left tail pipe. It looked to me like the carbs were rebuild, based on the traces of RTV around the bowl seals. Which means to me that the carbs will need to be rebuild again without use of RTV. I also suspect that anybody that would use RTV near gasoline might not know to keep all the pieces separate and numbered to each carb, which I experienced on my 700 Sabre (another V4). I have a few questions on the carbs used here, specifically how to tell which jets go on the vertical carbs and which jets go on the horizontal carbs. I usually get parts for my Sabre from the V4market, but they don't have the carb kit listed for the 500 Interceptor. Does anybody know if the kit for the 500 is the same as any of the other V4 carb kits (Magna, Sabre, etc)? Or is there another source for the carb rebuild kit? I will need to rebuild the master cylinder, replace the brake pads, all of which the V4 market has. I would like to change the drive/driven sprocket out for something geared more for freeway use though. ~8k RPM at 70mph seemss a little overkill to me. Are there any options?
