runing through the woods in nj,

no it glows when you are riding it to

I sent the tail pipe back to yosh to be fixed

the carbine cracked and was all soft half the tail

people i know say its running lean. 45/ 172 main

red fuel 1 1/2 out

[Wayward Son]

how does it run?

my cousin had a raptor 660. ran fine. the header glows red hot but is only visible at night. even my stock pipes on my kawsaki utility quad glow red at night. dont think its an issue unless its running bad.

so like eddie said: how is it running?

[woodcock87]

little shitty at the top end

hits the rev lim so

think i might try a after market rev box
