Big Bore Advise

What kits are most of these 90's running in the Nationals? My son is wanting to try some national events this year and I would like to keep him competative. He is racing a 2006 TRX90

Give Scott Cain a call 1-270-293-5120. He built the #3 90 prduction jr. quad motors and our motors all year. He does a great job and he is a very easy man to talk to.

We have been R&Ding different options with the TRX90. Hopefully we'll have something new by mid season.

We have come up with a 56mm bore the brings the displacement to 122. The good points with going this route are cost and it is easier on the bottom end.

If your looking to have your motor built then don't mess around and just send it to Robb's Racing Engine. As of today he builds the fastest and most reliable TRX90 motor......Period!

Thanks 4 all the help. I'm pretty sure I will have plenty more questions for ya'll. Building these little 90's is something new to me.
