Hello, i recently rebuilt my 01 400ex this winter and changed a bunch of in the motor, including hot cam stage 2 and cp stock bore 11:1 piston,

I also installed front yfz450 shocks

I do know i have a bit more power than before, but am having more difficulty wheeliing in 5th gear than before, am wondering if the problem is in the motor or the fact that these shocks have lowerd my font end and arent as bouncy as the stock ex shocks, also i installed slightly richer main jet maybe this is the problem? Any ideas???
