I just ordered a stage 2 hot cam, 11:1 comp. piston(85mm), and a gasket set today. The piston is the same bore as stock, its just a higher compression piston. WILL THIS WORK OUT? Here is what I have in my 400EX: HMF slip on silancer, Ground out welds on my stock head pipe, K&N air filter with air box cover removed, hi-rev CDI box, and a Dyno Jet kit. And I will be adding the parts listed above: stage 2 Hot Cam, 11:1 (85mm) piston, and a stock top end gasket kit. Will this set up work in my EX. I will probably have to mess with my jetting some. I might even take out my choke. But will I have any problems with this set up or will I be OK? Thanks for your help.
Does any one know what you plug the hole with in your carb when you remove the choke?

Just make sure you get your cylinder honed to the proper tolerances. It is a stock bore piston, but you want to make sure that your cylinder matches the specs that come with the piston. It won't take much to make it right. I'm having mine done...same set-up as yours by one of the machinists at Powroll. If you don't get it honed, you run the risk of seizing up your piston and breaking your connecting rod. I've heard of this happening many times on this and other forums.

With this set up I'm going to run 92 octane gas with Klotz octane booster. But after I break it in good; lets say a month from now, can I run straight 92 octane? I hope this give me a two stroke feeling, I loved my R. Hopefully I can keep up to the two strokes and Predators on the straights now, It jumps well and handles good but I just needed more power. It will be done tomorrow. Also I have a 170 dyno jet in it; will this jetting work out, will I have to mess with the fuel mixture screw or my pilot jet?
What do you plug the hole with on your carb if I take the choke out. Is it possible to just take the choke plate out and leave the lever on the carb, and this would plug the hole?
