I have had a HUGE string of bad luck with Tri-z's. I dont know why, but when I go to look at tri-z's for sale, I always overlook things. Its like I get into a trance and just dont look. I just bought a tri-z in pieces specifically for the motor. got it home, and the clutch cover was cracked straight through, with a nice big weld across the right case.
My first Tri-z I bought had a big weld on the right case, and was missing a bolt hole for the clutch cover, so it never seals up right. Cant screw in the bolt at all because the hole was broken off and welded without the threads in it.
Second Tri-z I bought had a bad motor with a jug that was ported and cracked across the whole intake part of the jug. And the bottom where the oil drain hole is was all messed up so it wouldnt hold oil.
This Tri-z came with an extra motor that.. Of coarse had a HUGE weld in the right case where the kicker is.
So now I bought an 86 motor online. I haven't received it yet, but after the guy shipped it, I noticed the top of the bolt hole in the right case where the bolt behind the kicker cover goes was snapped off.
So this brings me to yesterday. I found a Tri-z on Craigslist. Guy wanted not too much for it. Had no plastics. Original tires which led me to believe it wasn't beat up too bad in its almost 30 year life. Rear shock was blown. It was in the back of a storage unit. as a roller, and a couple boxes of the parts.
I got the boxes out. Alot of the stuff looked good. I asked if I could take the motor out of the storage unit and look at it. I looked it over. My friend that was with me looked it over. But the guy who was selling it all was rushing me pretty bad. So He said.. we cant get the roller out right now. But if I left a deposit I could take what I could grab, and pick up the roller the next day. I gave him a $200 deposit, which was half, and he let me take the motor, and everything that wasn't attached to the roller. Headlights, all wires, levers, motor, etc. Everything but the wheels, shocks, frame, and swing arm.
The second he leaves I pick up the motor and see oil on the ground. Oh great. Look at that. The clutch cover has a split on the under side of the kick mechanism. Across the whole thing. And there is that infamous weld in the right case.
Oh YAY!! My freaking luck. Got it home and felt sad.
He said it was a fresh rebuild from a year ago, with a hour of break in on it. New crank, bearings, piston, sleeve, etc. And he tore it down to powder coat and "restore it"
I looked down the plug hole, and there was a good amount of carbon build up on the piston. Hour my ass.
So I took the reeds out to look down in the cylinder and see the piston. Piston looks good actually, but for some reason the sleeve sticks out a couple millimeters on each side of the intake. So its either not the right sleeve, or whoever had it before the re-sleeve opened up the intake all the way around, so I am pretty sure the air flow going from a nice flowing intake to BAM 90 degree angle sleeve in the way is going to be kind of crap.
I really hope I can have some better luck with finding good tri-z motors and parts. My buddy got 2 tri-zs with no real issues for $50 each!! One was a good running 86 with an 85 motor, but not cracked up at all... And the second was an 86 in boxes with a great motor.
Let me hear if any of you guys have had as bad a time as me. Do you guys come across tri-z's with welded up right cases? I have gotten extra cylinders that are usually wrecked too. Someone usually tried porting it and went too far.
