CloneDo you have the key/plug in or not on the PIM?
You have a pipe now and it will rev faster... are you sure you're not hitting the rev limiter? You say it runs fine in 4th and 5th which will be harder to hit the rev limiter in. Makes me wonder.
Also the clutch could still be slipping in 1-3 gears causing it to hit the rev limiter faster than you expect and it may not have enough power to do it in 4-5 gears. Does your clutch lever have "play" in it?
Oh and a banshee loves sand and pavement so you were asking for it there. Thumpers have the advantage in the dirt where 2 smokers can't hook.
The plug is not in the pim that is correct? I will find out if I am hitting the rev limiter tommorrow with the fimak. What is the limit with the pim. My lever has about a 1/8 of play in it. Thanks Clone Anyone anwser these questions if they don't mind. Thanks for everyones help
