701 mod Bpipe on a 650

[550headache]

anyone ever done it? I put on in my square nose but cant get the jetting correct. Factory pipe says 115 pilot and stock needle & seat. Problem is it starts hard and loads up at idle. I went up to a 120 pilot and it would hardly run. 115 is back in and low adjuster is open 3/4 turn. still starts hard but ski ripps after 1/4 throttle. think I should drop the pilot down to a 110 or 112?

Factory Pipe once told me the b-pipe will NOT fit on a 650. The fact that you are running it says something. The lady who does costumer service is grouchy too. But anyways...

I've never done this, all I can do is give you some advice based on the protec pipe because I've had friends with both and they said they hit similar. This could mean NOTHING but..

135 120 jets and a 2.3 NS is what they run for stock 650 with the black protec pipe. I'll have to check on the pop off spring for ya hang on..

Oooh it fits no problem. they even made a 650 specific Bpipe. 120 seemed way too high unless its my popoff.off idle it hits hard and I couldn't be happier. starting and idle is the problem

I have the 650 Factory pipe chamber on my 701. Works great, but I'd love to try a real b pipe chamber for comparison.
