Jaredmacneill 27 Posted July 19, 2021 Hey I’m Jared I am currently trying to get my 86 trx 350cc 4x4 rebuilt . I found a engine but the owner told me two different years first was 89 now he’s saying 86 . He owns a local shop and wants $400 cad for the engine but I’d like to know how to tell if it’s a 86 or 89 . Thanks in advance 2 Share this post Link to post Share on other sites

jeepwm69 7,752 Posted July 19, 2021 Welcome aboard. I know the 86's I've had have had an extra vent on the crankcase that was deleted on later models. But I think that change actually occurred sometime in the 86-87 time frame, so if it's there, it's an early one. If it's not, who knows....... 2 Share this post Link to post Share on other sites

Fishfiles 20,147 Posted July 19, 2021 So I am not a 350D guy , but think you can't swop a 86 with a 87 up , the stator and wiring harness are different for one 3 Share this post Link to post Share on other sites
