No you do not need to run race gas... Just always use 92/93 and you will be fine.. OK my kinda performance report... Since I broke my wrist (and I sent my rear shock to CT Racing/TCS oh by the way CT has a new rear shock for the 400EX it is $850... I talked to todd and he says the performance on the new and rebuilt are the same.. He has a few people running the rebuilt and New Shock and there is no differrence in performance/handling)I cannot give you a ride report but a idle report
New FMF Bowerbomb Header and Curtis Sparks +6 degree timing key. I put a new sparkplug in for my test to get a read on the plug but until someone can get out and ride it I will not be able to tell about main jet size.. Well after about 20 min warm up (wasn't started for a week and a half) I hit the throttle.. GOD D**N!!! The throttlre response is amazing... In Stead of soundling like bbbrrrrooommmm it sounded like VROOOMM!!! I was like D**N... Couldn't get enough of the change of the sound.. I attribute that to the powerbomb flowing more air... It quieted the powercore a little just at idle.. Once you punched it you could not tell the difference in the sound level but you could tell the difference in power output(Timing Key)/flow of sound/air(PowerBomb)... SWeeetttt...

6 degrees sounds like quite a bit of advance... I know if I advance my V8 another 6 degrees (on top of the 10 degrees base advance it already has) it would ping like a sonuvagun. But, of course that all depends on what timing Honda was running stock.. maybe stock timing only has 4-5 degrees of base advance, in which case another 6 degrees would work great. Keep an ear out for pinging Skunky, and let us know how it does. Too bad you didn't get a chance to check the power increase of the power bomb and timing key separately.
