Well i want to keep my 400ex at its stock bore, but i want to get the most power by doing that. Give me details on the biggest piston i can use( I have a Wiseco 11:1 now, but i prefer to have a JE or Ross for reassurance), what kinda cam would be good for motocross (looking at the hotcam stage 2, HRC, and xr400 cams) what kind of valves and valve springs would be sufficient (titanium??), what kind of gaskets to use( cosmetic or OEM), if its a good idea to bore my carb to a 38mm or leave it stock, im looking into doing a port and polish job and i was going to do that for midrange ( does that sound good?), what kind of jetting would i have t do if i did any type of motor work?(I have a TC slip on and I found that there was no use for jetting its running perfect). I am sort of on a tight to average spending budget for all of this, if that says anything..... I was told by my motor mechanic that if i get tired of the above modifications or i carve "MORE POWER", he will make my bike a 440, using a new concept idea from L.A. Sleeve with there 440 sleeve( which is thicker and less resistant to heat), high compression piston, port and polish, Carillo rod, etc. My mechanic builds some very strong motors for A MX riders and Pro GNCC racers and I have yet to find one person who disagrees with his work. Tell me any of your setups or would like to comment on this post. later
