I understand that i am fighting the M-10, and should see a 3-5 mph drop in top speed. But i am far from the 112-115 range. Infact, hitting 120mph is not a goal i think is realistic, given the M-10 rear. Im simply trying to get the sled to pull through 100mph, like it did stock!

Im going to try removing the GP-1 exhaust, too loud for the trails anyways, and it sounds like a outboard motor going across, the lake.

I am going to leave the jetting and just change the exhaust, minus the prefilters.

I am also going to try 155, 150, 145 main jets,after i run with just the exhaust change, to verify whether or not i am rich, with 165 M/J

I am radaring again tomorrow, and will post results!

Any suggestions, Freddie, before i run??

My stock RX-1(144 carbide trail picks) won a trophy in the 4 stroke class running 95.3 in 1000 feet. in comparison my buddies 01(i think) Machz with base gasket kit Vforde reeds jetting gear change clutching and a crapload of chisletooths over 200 I think ran 100. His brothers ZL 900 Vforce reeds clutching gear change jetting and chisel tooths ran 97. This was in 1000 feet. I am not sure but I think some decent traction and suspension setup I could have taken the ZL and with Freddies kit and a clutch setup I think I would have beaten the Machz as well. All that and 10 times the dependability of a 2 stroke.

Oh forgot to mention one of if not the fastest sled out there was a turbo RX-1 he would half throttle it for the first 100 feet or so to get rolling before he could nail it. 139 I heard from someone there was his best of the day
