Question about 2001 Yamaha XVS 650 Dragstar Classic
Use a DYNAJET kit & go with the directions. Or check with the Hypercharger manufacture for correct jetting. But you will still need different needles & main jets for those pipes.

First off did you buy it new? Second has it gone through its break in tune up yet?Did you do the re jeting? My guess is it was re jeted wrong & neeeds to be re jeted again or could also need more air(upgraded air kit) or a tfi or power comand fuel mod.My bike also poped untill I did the air & fuel upgrades & them upgrades will also give you a much needed house power needed for this rig.
Bring it to a shop & have it looked at.......

Take the hypercharger back off. The carb uses fuel according to how much air sucks through. You are putting alot more air through the carb, so it sucks more fuel into the engine. Even if your not burning all the fuel, it's running through anyway. That's the downfall to a carb.

Any reason you had to change the jetting??New pipe,Intakes.?But,even though you may have it a bit rich on idle the pipes WILL get very hot,very quickly without some sort of air flow over the front of the motor and radiator.At the very least,have a strong fan blowing directly on the front of the motor if you are going to let the bike run and you are not riding it.I have seen the white plastics in front of the radiator distort from the radiant heat.Don't idle them for in more then 20 seconds.It can do heaps of damage.Ride the bike and see if its running well.When you stop,turn it off.All the yz and wrf will get very hot at idle.Hope this helps
