BB jetting question

Recommended Posts

Looking to order CW 434 kit, already have the FCR39 that came from SSW set with perfect jetting. Since it was set I don't have a clue what the settings are. I am 0-3000 feet with 3x3 and FMF PB header w/Powercore4 silencer. Wondering if I need to change my jetting when I BB? Any other tips for the build are welcome too!

you can get the 434 kit.its just 4mm larger than the stock piston.if you addd a stroker crank(+4mm) it would be a 462.

as for jetting the BB kit i would go 2 main jet sizes lower that what your at now

Another question on BB, while I have my head off, can I shoot my valves with a spray of carb cleaner or something to freshen them up? They have 4500 miles on them and the bike has not been run hard as I am the original owner.

Thanks for the advice Craigo, but I'm on a budget so buying the big bore kit is already putting me in the dog house with the wife. Checked my cams and my valves are still in stock specs. Just thinking a little cleaning while I have it apart would help.
