Posted by: scott58976

How much do u think my 300ex would have?
How fast to u think it tops out at?

Mods Include:
Wiseco .80 over High Compression Piston
Precision Port and Polish & 3-angle valve job
HMF full exhasut system
Jet kit
K&N Air Filter with lid off
14/36 Gearing
22x11x9 BKT X-drive rear tires

Do u think i would keep up with a stock 400ex and do u think i would be able to beat a blaster?

Thanks

Honestly, even with all that..I don't think you could. I mean..If it's a short race, yeah. But if you have to shift above third, the 400ex will always prevail.

Stock 13/38 w/ 22" tires is 55mph

14/36 w/ 22" tires will hit the rev limit at 62.5mph

Should be about even with a bone stock 400ex (stock pipe/filter and lid on). Chang anyhting on the 400ex, and you're toast agian.. lol. 400ex is just a much better motor.

Should be able to beat an average piped blaster. Any motor work.. and they are going to beat you again, though.
