Help with an order...


Recommended Posts

I can finally order a fcr now. I had a roof that needed replaced on my house along with some other things so this kind of stuff has been on hold. I need to know what all jetting or other parts is recommended along with ordering the 39mm fcr TT kit. Should I get the JD jet kit or is it not needed?

My setup

434cc, single layer base gasket, stage 1 hot cams, 3x3, mrd ssw

I'm in PA and ride between 600-2000ft

What does the ocemp needle do vs others? Is that for the altitude?

What does the ocemp needle do vs others?...Makes he bike run correctly

Is that for the altitude?...In some cases yes...In your case mostly due to being big bore displacement...ocemn will run reasonable well here, but I have found the emp to be better
