frocashmoney24 Posted February 11, 2004 Report Share Posted February 11, 2004 you might have to move up a few jets to get it dialed in right again, then adjust your needle Quote Link to comment Share on other sites More sharing options...
Ducman Posted February 11, 2004 Report Share Posted February 11, 2004 You need to go up on the main jet size and possibly the pilot but it sounds more like a clogged filter or something since stock jetting should make it run realy lean with the K&N. Lean conditions shouldn't foul a plug. Did you buy the filter new? Someone may have used the wrong filter oil for it. Foam filter oil will clog it up. I would clean it and apply K&N oil on the filter (the spray stuff) so you will know the filter is flowing air correctly. You can get a K&N filter cleaner and oil kit for $10 at any auto parts store.

Banchetta Posted February 18, 2004 Report Share Posted February 18, 2004 240 mains, stock needle clip, stock pilots....I think you just need to adjust the air screws...they make a big difference, especially w/ stock pipes...you should have a crisp throttle response..I always had a hard time not fouling plugs w/ stock pipes, put pipes on and never fouled another plug....

joshp66 Posted February 18, 2004 Author Report Share Posted February 18, 2004 yeah i was messing with my airscrews today and i got it to rev up faster but they are like 2.5- 3 turns out, still smokes a lil i guess ill try the 240 mains in there Quote Link to comment Share on other sites More sharing options...
Banchetta Posted February 18, 2004 Report Share Posted February 18, 2004 If it likes the 2.5-3 turns out better, than your running rich....Do you have stock pilots in there???? Quote Link to comment Share on other sites More sharing options...
joshp66 Posted February 18, 2004 Author Report Share Posted February 18, 2004 yeah there stock , yeah man im running real rich all my stuff is stock, so u think 240 mains still or no? Quote Link to comment Share on other sites More sharing options...
joshp66 Posted February 18, 2004 Author Report Share Posted February 18, 2004 should i drop some new pilots in there too? if so what size?? thanks again Quote Link to comment Share on other sites More sharing options...
Banchetta Posted February 20, 2004 Report Share Posted February 20, 2004 I've never heard of anyone running leaner pilots than stock which is a 25. Your elevation must be really high.....The best way to dial in the mains is to run it wide open in 6th gear for 5-10 seconds, shut it down, pull the plugs and see what color they are......go from there....as for the pilots, try some 22.5's...either that or get some pipes and that'll lean it out..

Ducman Posted February 20, 2004 Report Share Posted February 20, 2004 Yeah, bust out the credit card and get some pipes. Messing with perfoamance mods on the stock pipes is more trouble than its worth. Quote Link to comment Share on other sites More sharing options...

Period. If your having trouble idling, then it's the pilot/airscrew. What is your elevation???? If it's really high then you might back off just a little. The ONLY way to check the main is the wide open throttle test. DO NOT go messing with the main until you check the plugs at wide open throttle to verify that they actually need messing with. Cool, take it easy. Scott Quote Link to comment Share on other sites More sharing options...
