Rotten-UK Posted January 8, 2012 Report Posted January 8, 2012 (edited) Im trying to get my jets right for the colder weather having not riden since summer... stock motor, k&n 6" pods & outer wears, pt mids, sea lvl - 300ft, average temps out are like 2-8C... for summer i had 27.5 pilot, 290 mains, needle clip in the middle & was a lil rich on the pilot. Now i have changed just the mains to 310's, revs up nice, crisp and clean as, like "Vrrin Vrrin" but coming of the revs it will splutter/ pop off a bit when the revs drop, if you get what i mean its not clean, it just doesnt sound too good to me. Have i gone to big on the mains and its over fueling and still burning fuel when i come off the throttle? thats kinda what it sounds like to me but ima noob, any idea's? Thanks Rotten.

Surfrjag Posted January 8, 2012 Report Posted January 8, 2012 Clean out your pilot jets.. then do a plug chop. Have you tried richening up the air screw by turrning it in say 1/2 turn each? Where is it now? Quote

Where is it now? I took everything apart and cleaned it when i changed the jets, put new plugs in too. I never really notice much difference by messing with the screw, its 2 turns out at the mo... Its running ok, feels like the jettings on, powers sweet right the way through, it just doesnt sound clean/smooth... Quote
Surfrjag Posted January 9, 2012 Report Posted January 9, 2012 Running lean pilot could do that. Have you tried a 30 pilot or even a 32.5? Quote

Rotten-UK Posted January 9, 2012 Author Report Posted January 9, 2012 Meh... ordered the pilot jets but i dont think its that coz it still feels rich on pull off. maybe i didnt explain very well, its more pinging/lot of buzzing about up front in the pipes when i come off the throttle or sat in traffic in 5th-6th gear doing 30-40mph. My mate says its just the way a 2 stroke sounds and im not used to it not having riden for a while, Im sure it never sounded like that before... Quote
