Message: [QUOTE="Aholland, post: 386839, member: 32181"] I think people also have to aware that sometimes perfect jetting does not result in huge amounts of power. they sometimes expect too much from their bikes. Perfect jetting to me means that the bike runs clean, produces the maximum power that is possible for the engine combination and naturally never fouls plugs. I find my jetting to be much different to others as I run Amsoil synthetic oil at 75:1 (never had a problem in 15+ years). My only issue is with jetting my TMX carburator at low rpm's. I have a large selection of pilot jets (every one available) and have had no success with being able to get any adjustment out of the pilot screw (should be sensitive within a 1/8-1/4 turn of the air mixture screw. It loads up a bit at slow rpms, but never fouls a plug. I live with it because I believe it has a lot to do with the porting/exhaust etc that has been done to the bike. In the end, I just want to ride. As a side note, I have found that black socks at knee level attract more heat which effectively lowers the air density on either side of the airbox resulting in a richer mixture. I prefer to select my sock colors depending on the temperature (white for hot days, black for cold days). That way I can fine tune the air density at the airbox and resulting air/fuel mixture.
