yes,its to small.you need to be more like a 180 main jet.

:banana: :banana: :ride: wonderfull job eddie ...

i put on a 175 mj (didn't have a 180) , dropped the needle two clips, and

revvvvvvvvv!!!! bike pulls hard! top end ripps and low end is much better.

no more bog:p .

needle position worsened rich condition due to too much ap squirt at sudden opening of throttle as you stated.

Now emr needle is 5° clip but feels like i could drop down one clip more 'cause revving is strong at 3500/4000 rpm. lower rpm has no bog as i said but most of the power comes later.

175 mj feels way better than 155 but then i also feel it could be increased.

as i said my airbox (i put on an e model airbox) is cut on top as much as it could ad all cut on right side.

do you suggest triyng a bigger mj (i only have a 190 at home) or try to reduce hole on the right side to see if its better?

and what do you think about needle clip position? should i try to drop it to improove low end?

thanks

las qt eddie:

i tried the bike without side panel to increase air and see if it was lean at high rpm..it seemed to run the same as if it was on..
