LT80 questions

[teamclean911]

I am about to freshen up the top end on my son's LT80 and am thinking about milling the head a bit to give it a bit more "snap". The bike is 100% stock at this time. Does anyone recommend this and, if so, how much should I have milled off the head? I run premium gas in this bike.
Second question. I would like to increase the suspension travel a bit so that it doesn't bounce when he jumps it, but I don't want to invest a lot in after-market shocks. Can I replace his shocks with stock shocks from another quad as a decent compromise, and, if so, any recommendations? His quad has the widening kit on it, so a bit stiffer shock would be good.
Thanks.

well what year is it ? i know some of the older ones had a restrictor plate in the exhaust (washer with a small hole) taking that out will really wake one up !
another thing you can do is lighten the weights on the front clutch a little to give it a little more stall rpm

i have a 1989 lt 80 does this year have a restrictor plate in the exhaust if so where is it and how do you get it out.

mill exactly .020 off the head ,polish the dome and squish band also get a bigger carb

it's right between the cyl & exhaust pipe just take the pipe loose & most of the time they fall out

Dont forget bout the one in the carb slide......More than likely they have both been taking out tho, Do it at the dealership 99% of the time when there sold new..
