Ok so I've seen a lot of the posts but almost have this eBay spike figured out. So the mods to bike are cobra straight pipes eBay spike and pea deleted. I have put in a 52 pilot jet and a 170 main jet. Turned screw to 2 3/4. After changeling this I couldn't get the bike over 40. So I started to shim needle up. I have 6 #4 washers under stock needle. Going down road at 55-60 spits and sputters but if I pull choke out all way and hold with bottle cap and clothes pin I can drive anywhere but when I back off from wide open bike actually picks up. The pipes are turning blue so all this should tell me I'm going lean. So should I put a 190 in it and bring the needle down? The bike feels like I have a lot of power down low but nothing up top.
