Yamaha 1985 Trimoto 225 dx top end questions

[berensboy]

I have a 1985 YTM225dx I've had collecting dust for a while and I decided to get it running. it needs a full top end re build and I'm having trouble finding parts. Will the bigger Yamaha 229cc jugs and pistons work on this? I cant find a stock 223cc top end kit anywhere.

Ttr225 dirt bike is supposedly the same top end, not positive though

229 cc as in a Timberwolf cylinder? Yes it will. When I did this, I also had to use the Timberwolf cam chain tensioner.
