Thought's on a 250 85 tri-z

Hmm how could it be overheating it was like 40 out. He said something about I need to look up and make sure the rad hoses are on righ

[90guy]

It could be over heating if that thermostat is stuck shut or if that water pump isnt pumping fluid. Which could be do to the hoses hooked up wrong.

[volfan537240]

Running lean, water pump/thermostat failure, blown head gasket etc could cause overheating. Outside temps would have nothing to do with that.

[BiGDawG]

Anyway to tell if there hooked up backwards, and how can I check the pump / thermostat.. Seems like if it was a blown head it would be smoking bad

buddy decided to pull the sign off the back of my truck and jump in the pic lol i really need a larger drop hitch lol





gotta work tomorrow night then i have monday and tuesday off i need to get some gas and oil then i'll try to get a video of it running

[volfan537240]

Hoses should go from the head to the top of the Rad, water pump cover to bottom of the Rad. Have you looked at jetting? I'd do a wide open plug check at the very least to make sure its not running lean.

Did someone just overfill the overflow bottle? Pop your rad cap off and run it check for circulation, get some better pics of that swingarm cleaned up...looks very similar to mine.

Obviously, keep it simple first, but I just put a head gasket on because mine because it was pushing fluid out the overflow tubes. It wasn't smoking other than the normal 2 stroke smoke , and even pushed 170PSI on a compression test, but that is the only thing I did and it fixed it.

They fit larger guys well.

Be aware of the kickstarter case cracking (jet it right for a 1 kick start), Also waterpump and fuel pumps can all be an issue.

They are fast!

[BiGDawG]

yea it starts first kick, i'll check the hoses and flow tomorrow or tuesday them are my day's off, gotta work tonight and i'll get better pic's with my camera instead of my phone lol


also it has the baja light's on it but he said they have never been hooked up, need to look into hooking them up and finding a grab bar / taillight also could use new foot pegs sitting on the bike it would be the right foot is bent down

[tri-Z ripper]

right side foot peg always leans because of kick starter. I put a clean little bead of weld under the foot peg stop to raise it up even. Also you can look at raffas foot peg replacements in 3ww store.

[BiGDawG]

Ah alright guess it wasent that noticeable once riding, uh he said its oh had premium and yamalube 32 - 1, gonna pick some up some gas and yamalube tomorrom guess I need to find a gas can to use

[BiGDawG]

Hoses are good, fluid was moving..

[volfan537240]

Running lean, water pump/thermostat failure, blown head gasket etc could cause overheating. Outside temps would have nothing to do with that.

..........

[BiGDawG]

how do i see if its running lean? and how hard is it to replace the head gasket..

[oile]

I'd check the water pump every Tri z that I have bought has had a bad pump.
