Hey zman2 we shaved the head on our 90 10 thousands and did not have any problems but here is the low down on the specs.

Stock head gasket is 40 thousands.

You can purchase a thinner head gasket from RobbsRacing.com it will be 20 thousands.

We are running the thinner headgasket now with the shaved head (10 thousands) which means we have given up 30 thousands and have no problems at all.

A lot of people elect to run the thinner gasket instead of shaving the head incase they need a stock head at a later date and the gasket is probably cheaper.

Get the timming advance key and standard over bore and that quad will really wake up.

Good Luck,

you guys are killing me with the call hetricks
charles does nothing but trx90's.
it is kinda like calling the ford garage to put parts on your chevy
don't get me wrong mr. hetricks is a nice guy, but i have'nt seen to many of his built trx90's.

He is the guy that that started a thread on the other site about someone elses TRX90 winning a race...and that started an all out 4stroke, 2 stroke, your kids bike is illegal and my mother can drink more than your mother type of thing.

Rich does great work. So does ICRACING, and so does ROBBS

there are alot of guys who can get you what you need.

Goodluck

give rich a call and ask how many trx90's he does.
better yet go on his web site and see how many trx90 aftermarket parts are listed.
then let every one know
no dig on mr. hetrick but he does mostly 2 stoke stuff
yep i said the honda can be made very fast
if you can read and think for yourself about the other site, never did i say a 2 stroke was bad, just the silly comments by the experts on how a honda can't be competative, are just that, silly.
i don't care if you have a 2 or a 4 stroke. let your kid have fun.
right, you are posting who you know. so you know rich does a lot of work on trx90's or are you guessing????????
sorry i have never seen robbs quads run. i don't guess. i'll just post on what i have seen.

Mike,

THAT'S AWESOME!!! CONGRATS to the KIDS!!!!

We don't race or anything like that...we are more rec. riders. Just something for the family to do on the weekends,vacations and what ever other time we have to spend togther. We have the Predator 90...2stroke!~YEP!

I have been looking at the TRX90's. They are dam good quads.
We'll see if this thing gives us any more trouble. If it does then it will be looking for a new home and I will be seriously looking to buy the Honda.

If that ain't the truth!!


We like the Predator, I had a problem with the the stator dying. The 03 Stator really has no protection from water and the mud, hence causing the mud and water to get up in there. We found out that the 04 has an air duct type of system so we will be adding that on to ours. Hopefully everything will be ok after that....I HOPE!!
