I need some suggestions, just did a mud race, hare scramble. I did well, my setup is as follows; I ran a stock cylinder, wiseco piston, jetting stock except 400mj, needle in third position, fmf gnarly with a turbine core 2sa, 05 base gasket w/110 octane race fuel, 9oz fww. This is about engine so I won't bore you with the rest. I won the race, and can say lugging hadn't been easier since my cr500. Plenty of bottom, lots of steep muddy hills with no run to them and it ran like a top, gearing is 13/49. I pulled 450s up hills and through woods-here is the BUT.....top end suffered from that setup, fell on her face on long straights 5th gear tapped out. Next year is a big season for me and I'm getting ready to switch a couple things to have that torque but not fall so hard up top, here ids what I was thinking and hopefully some will help with different opinions: 1) get a mo betta port job from eric gorr and then run a pc platinum with pc sa 2) go 265 bb kit and run stock pipe 3) maybe the platinum 2 will give the same torque but more run out up top? The platinum 2 would be cheapest and easiest, but not sure about how it stacks up against the gnarly, which defiantly gives bottom but kills top. Any reviews of platinum 2? Any suggestions to manipulate what I have or is forward motion the winner? Please help, getting my cash together now and am at limited test time.if it wasn't so wet Sunday I would have gotten my booty handed to me because I lacked that top end!
