Jets What size are stock jets in carb. on 2001 FLHR Roadking

Since I haven't ever heard of an FLHR-Y, I can only guess at the size of the carb. If the engine is the standard twin cam 88" engine, the carb should be a 40mm version. But, if the engine is one of the "factory hopped up jobs" such as a 103" or somthing else, I have no idea of the size of the carb.

I'd start with a #50 slowjet. You will probably get backfires on decel with no back pressure in the exhaust.

Most of the time a standard starter motor works fine with a stroker motor. The stroke of the motor has nothing to do with it being harder to start but the compression does. If you're running 10:1 compression, you may need a stronger starter motor. However is I just had the engine built, I wouldn't mess with the starter until I had to. I've built lots of 89" Evo's with 10:1 compression and the stock starter started them all just fine. Starters are expensive and I wouldn't replace the stock unit until I had to.

To change the motor, you'll have to remove the outer primary so you can take the starter jackshaft loose. Disconnect the battery first. I know you would like to keep all your fingers. Then, from the right side, remove the exhaust system and everything else that might be in your way. Take the battery cable loose from the starter motor at it's connector. There are two large bolts that hold the starter in, remove them and the starter comes right off.

Good Luck

Hello,
Your FLHR may need to have the carburator cleaned out. The fuel that we are getting now is very unstable and and can gum up very quickly. the idle or slow circuit in the carb is very small and can be pugged up easily. Removeing the carb and cleaning it out is about an hour and a half job to do properly. The fuel in the tank should be drained out and replaced with fresh fuel also. some people will simply siphon the old fuel out of the tank. the carburator is delicate and precision so it should only be repaired by a qualified technician. beware of the " miracle carb cleaners" they often do more damage.
