Bogging

[Newbie]

Just finished my second build, and I am having some difficulties. When I ride the bike hard, it bogs down quickly. It seems like it is starving for fuel. I have checked the plug, and it is a sooty black, similar to my old bike, which was oddly problem free.

Sooty black = Too much fuel... U need a smaller jet size.

Fixed it. Luckily my problem was simple. The choke lever would bounce up and down when vibrated under high revs. Took off the airfilter, tightenened the choke lever nut and bam, problem fixed.
