Probably newbie 90 ?'s

[ROTTY261]

Both my daughter and my nephew are on 07 TRX 90's. They are both bone stock with the exception of tires. Can anyone give me a good place to find a carb that has some adjustments on it? Also I would like to see more power of them as easily and cheap as possible. They have both raced wee quads and are just now moving into the more competitive class where we need power. I want to do it cheap so I can focus on suspension for my high dollar items, thanks for any help....

tboltusa.com has a 114cc kit. it includes carb,head,cam,piston and cylinder for $449.00 i dont know anything about their products. i was going to get it but my son started to jump pretty hard on his 90 and was afraid with more power he might get hurt.

We have everything that we know fits and works on the trx 90.
Not saying tbolt doesnt,just another option.
We have a carb that bolts to your stock manifold and air box,if thats what your looking for.(bigger ,adjustable, ect.)
