VF500F - Top End Modifcations - Tech Questions

Just got into stripping the carbs down never seen so much varnish on a bike. So bad its turned Black and all blocked jets and anything else it can. Anyone got a good solution......???????????

 

A good tech manual could be of help: Cleaning the Honda V4 Carburetor, by Mike Nixon

The Motorcycle Project Book Nook

 

You know, in those cases I've never been able to get the carbs clean enough to function again. Probably easier (and maybe cheaper) to just buy a good used set. You can try cleaning them, but don't be surprised if you continue to have trouble with them.

Good luck!

 

All I might be like a million years behind on this but..... Proper warm up before leaning on the VF500 motor is the key! I have an 84 or 85 model that well. Check out my FB pages Joe Heffernan, Foil Hat Racing, and Bikes Built Better as well as websites. I have been land speed racing the same VF500 since June of 2011. It's turbocharged, and the turbo is fed oil tapped off the oil line to the rear head, regular oil changes of course. This motor had 43,000 miles on it before I started putting it to such abuse. This motor has close to 30 LSR passes on it as well as 20 or more FULL power dyno pulls with as much as 14 PSI of boost applied. The motor has also seen 13,500 RPM spikes as well as sustained (30 sec) at 12,500 (covers two miles in a hurry) I am interested in learning what people have found and am more than willing to share what I know. This is the real deal! I have four records at bonneville SCTA and another four with the ECTA. Best speed is 162.24 from a standing start in a mile. - Joe

 

Holy Shit!
