Yamaha TRX850 Enthusiasts Forum

Gday all!
Just a quick query, about to replace my stock engine with a grey import from the wreckers... Any compatibility issues between the two that I should be aware of? Bottom end is gone in mine but Its my spare trx so slowly building it back up
If anyone happens to have a good engine in Australia let me know ...the wrecking yards are hard work!
Thankyou!

Most grey imports are pre 97 so good chance you'll have to address the inlet valve issues.
If your head and cam bearing surfaces are ok on you Aussie TRX ( as long as it's 97 onwards) you can swap the heads around at the same time.
