Hey everyone! I bought a compression tester today and checked my 87 trx 350. It is 158 pounds. Manual says from 172-206 is spec. I just did a valve adjustment so I'm pretty sure that's not the cause. Think I need new valves? Seats? Both!!?? Do you think i can ride it for the summer and save it for winter project? I mean it's not THAT low! It starts great,runs almost perfectly and has plenty of power for a 350. I do ride a lot though. I juse didn't know if there was a magic number you shouldn't let it get below. Thanks a lot guys. Any info much appreciated!!
