I went from t5s to cpi years ago. I wouldnt recommend cpi for trails. Keep the delivery low with t5's.
Hjr can best answer your questions. Its his port work
So far redline is the only one who can port a serval without losing power down low that's ive seen dyno charts on here.
I rode one 4mil cub on race fuel in trails. Never again. That motor was terrible in trails. Although in the drag race it was beast mode.
keep coolant on it. But if you stay in a cut and keep coming out the coolant can shock the tool and make it brittle and brake. Although you shouldn't have a problem with that on gears.
slow as in feed rate or rpm tricked? Very different things. Can you clarify for him please.
My explanation that mines around 40-42 is thats what i read on thumper talk. as for 70 on meth, good god wtf.
2005, you need a go pro man. good video/race though. the 700 raptors are another animal though.
Id replace the old stock crank with a 4mil. Perhaps a 4mil serval or 4mil stock cylinder bike with port work. I think a forum sponsor who does port work can best help you. Tell him what you want and yall can work on your needs and budget. Id also split the cases and replace seals and bearings since it's sat for so long.
Looks like mine might be shot too:

Then i will make sure i get SS braided lines with my banshee brake components. Any other recommendations while it's down to the frame getting rebuilt? It will be at +3+1 as well.
the camaro saddens me man. That car is way too nice. I hope you can save the drive train(if it's in there). Id say it should make well over 1500 with that turbo. I know the 76 i wanted to put on my truck would of been good for 1200 in my little 330ci.
