I have a 2000 shee and it is completely stock except for wiesco pistons still on stock bore. I will be adding dual K&N clamp ons with outerwears, i will remove the air box, about what size main jet should i use? I am already running a 210 main and my riding temp is anywhere from 50-70 degrees. any help is much appreciated.

I'd go up to 250 mains and do a plug check at wot in 6th gear for 5-10 seconds....

I was just wondering, someone told me that if i used this setup i would get my pipes too hot because too much extra air would build up in the stock pipes. Any truth to this. Also what would happen if i took off the endcaps on my stock pipes, just wondering?

I agree with Banchetta, up your main to around 250-260 area and do a test to find out how it is running on the top end and you may need to change pilots, I doubt it. Good luck.

I wouldn't be taking advice for that person anymore........
