r2n2d Posted January 30, 2006 Report Share Posted January 30, 2006 I currently have fmf sst pipes, coolhead 22 or 21 domes, k&n filter in airbox with lid. no snorkel. I ride near sea level. (0-maybe 500 ft) Cape Cod, MA temp ranges from 40-90 degrees I had jetted my bike with the stockers at 280 main, 27.5 pilot. needle in the middle what would be a good starting point for me, with the keihin 28mm PWK's?

r2n2d Posted January 30, 2006 Author Report Share Posted January 30, 2006 the guy that sold them to me told me they have, "The jets are 135 main jet, 38 slow jet, 3.5 throttle valve, and JJH needle" Quote Link to comment Share on other sites More sharing options...

r2n2d Posted January 31, 2006 Author Report Share Posted January 31, 2006 I'll start there thanks for your help. also would you recommend a dial jet for those carbs and if so where would I get them? so I can dial in faster than rejetting everytime. just a thought.

cbryant_2 Posted January 31, 2006 Report Share Posted January 31, 2006 160 mains may be rich. I have 148s with an LRD needle in 4th position on ported cylinders. All riding done @ 0-300'. Quote Link to comment Share on other sites More sharing options...
r2n2d Posted January 31, 2006 Author Report Share Posted January 31, 2006 what size pilot? and is the lrd needle alot better than the keihin one? I think they may be the same 148 on 4th clip and 160 on 2nd. because the needle is stitting lower in the 160 where as yours is on the 4th clip making it sit higher. I think! but then again I am here looking for a spot to start thanks for you input. Quote Link to comment Share on other sites More sharing options...

I also think the 160's may be fat. but better fat and change a set of plugs, than lean and change a set of pistons Quote Link to comment Share on other sites More sharing options...
r2n2d Posted February 1, 2006 Author Report Share Posted February 1, 2006 thanks I think i'll go with the 160. I am still waiting for the carbs so i'll keep you's posted on what size worked the best. Quote Link to comment Share on other sites More sharing options...
r2n2d Posted February 8, 2006 Author Report Share Posted February 8, 2006 I had installed the carbs on my shee with the main 135 and the pilot at 38. It started first kick and stayed idling. It was bogging out when I hit the throttle. like it was trying to catch up to its self. After like four sec the mid kicked in very strong and the top was better. Do i change the pilot even thought it started right up and idled or do I change it to the 42, which I am still waiting to be delivered? Also should I run a 155 main instead or the 160?

r2n2d Posted February 9, 2006 Author Report Share Posted February 9, 2006 So before i switched the jets I started it and it didn't start first kick it was like a few. I then switched to the 160 main and the 42 pilot needle 2nd clip(2nd from the top). It started with both chokes on on the second kick but it began reving higher than it should at idle with the chokes on and backfired. I turned the choke off and it shout off. it still was hesitant when I start on the gas. what should I do? Quote Link to comment Share on other sites More sharing options...

Is it pulling harder with the 160's, if so ride it a little bit and check your plugs. If it seems to be a little slower, or chugging on top the main may be to big.

r2n2d Posted February 10, 2006 Author Report Share Posted February 10, 2006 I ran the bike today with the needle on the 2nd the clip 160 main 42 pilot. It was strong in the mid but it seemed alittle slower on the top. When I move the clips down to the 3 or 4 will it effect the top alittle? I have to do it for the hestiation anyways. but just thought I would ask before then. Also did the plug test. It was a light gray brownish color.
