Oh wait.... This can't be fixed with paint and brush, so carry on with acting like an asshole. I'm sorry sir! I’m trying to learn something here and your babbling and misspeaking makes it tough and yeah I’m a painter....you’re a mechanic....what’s your fucking excuse?

The coolant washed the lubrication off the skirts and scuffed the piston. That is for sure not a lean burn down. There isnt even the slightest amount of aluminum missing from the top edge of the piston on the exhaust side. And no aluminum was drug across the top ring and ring groove. Not a lean burn down. Okay thanks Tom I wasn't sure Quote Link to comment Share on other sites More sharing options...

Maybe that is the side with the cracked carb boot. It needs close inspection for sure. Not terrible lean but a little lean for sure. Quote Link to comment Share on other sites More sharing options...

It may be as simple as jetting. It may be something else. Dont just ignore it or think the new carb boots have fixed the problem. No sense in making this more expensive than it needs to be.

On the Bold... I was leaning towards this theory as well.... I don't know about the cat triple, but I do remember that the polaris 650 triple, as an example, had a different jet size for each of the Mag, Cen and PTO.

Platinum Contributing Member Skidooski Posted March 28, 2018 Platinum Contributing Member Share Posted March 28, 2018 Staggered jetting is fine. You give each cylinder what it wants. Quote Link to comment Share on other sites More sharing options...

Point I think here is that during a rbuild, it is important to make sure that each carb was put back to the proper cylinder so that the jetting is correct for each cylinder. Some don't know this and reasemble thinking it doesnt matter which carb goes where. Quote Link to comment Share on other sites More sharing options...

If someone is tearing down a motor not labeling things and keeping track then they should have someone else rebuild it for them. Label them P, C & M or 1, 2 & 3. Carbs, cylinders, Heads / domes, Exh valves etc. Everything is dedicated to a specific cylinder. 1 Quote Link to comment Share on other sites More sharing options...
f7ben Posted March 28, 2018 Author Share Posted March 28, 2018 Usually the center cylinder is leanest on these motors. Gs....did you run the motor much after the exchanger started leaking. If it got hot that could explain a lot. Quote Link to comment Share on other sites More sharing options...

The mag piston has most of the wash burned off it. There is only black on the front edge. On 3/27/2018 at 11:34 AM, GreenStreak said: The mag piston has almost no carbon color on it.

1jkw Posted March 28, 2018 Share Posted March 28, 2018 My bet is anti freeze leaking in on the clean piston. Guys clean model airplane engines in crock pots with anti freeze all the time cleans carbon right off. Quote Link to comment Share on other sites More sharing options...

Correct.......its not good for pistons although maybe part of that is burning it. I had an engine that had been eating coolant slowly for quite some time and the pistons literally crumbled. I had never seen anything like that. I bought it used and didnt know it was consuming coolant.

Platinum Contributing Member Skidooski Posted March 29, 2018 Platinum Contributing Member Share Posted March 29, 2018 I don't know Cat triples but on the Doo triple, if the water pump seals go bad it will pull coolant around, past the pump gear and main bearing and right into the bottom of the Mag cylinder. Is this a similar case with T Cat's? GS did you clean and re-lube the crank and main bearings before it starts to get corrosion? Quote Link to comment Share on other sites More sharing options...

GreenStreak Posted March 30, 2018 Share Posted March 30, 2018 Got the old front heat exchanger cut out and mocking in the 97 Zrt600 one from ebay. It's a perfect fit. Bottom of the exchanger is getting stainless 1/4" bolts and stainless nylocs and the sides are getting tig welded back. Happy with it so far.
