No. It's a completely different engine.
You can however use the head from an '85-'87ATC250ES BigRed, '85-'87ATC250SX, and the '85-'87TRX250

Sounds like it ran out of oil. Did it or did the pump quit working? Clogged screen?
Better figure it out before you throw a new head and cam on it.

Hi all. Got a little question. I have a bud with a trx 300(I know, it has 4 wheels). The cam galled, and messed up the head and cover. Got another bud with a 350x, completely trashed, but still runs. Will the head from the 350x fit the trx 300? Hate to part the trike out, but it's pretty much a pos.
Thanx

Well, that's what I was afraid of. Your info does open up some new search possibilities though. Thanks for the input.
