250r engine on 300ex frame?

[eastPAex]

I have a 98' 300ex i really like the way this quad handles and feels, but the engine is getting tired and i want more go. I am more than capable of making the swap. Just wondering if anyone has tried this before? I am looking for others opinions on this so feel free to add any positive coments.

You would probably be better off with a full 250R, they feel alot better than a 300ex, but i know this swap is possible:cool:

i would love to have a full 250r the problem is i cant find one in my price range. but i do have a 250r engine i tried a trade but no one wants a 300ex for a 250r. but thanks for the info

Sell the motor and the 300 and buy a 250R.

You are better off getting a real 250r, or upgrading your 300ex motor. The 250r motor is just too much for the 300ex chassis to handle.

i have seen at least a dozen people that you are talking about, and they had nothing but good things to say about it. actualy i think i saw some on this site i go look for the pics

EDIT i search for awhile and i could only find one, so here you go
