I recently became a first time owner of two Indy 650 triple sleds. Both are vintage '88 & '90 with the '90 in the worst shape in terms of the body. Apart from cosmetic work and a couple new parts (water pumps are unbelievably expensive!!!) the engines sound strong and don't show significant signs of wear. The '90 PTO side piston shows slight scoring on one side of the skirt from the bottom up to the rings, I am a little concerned about that. The '88 has about 160 hrs on a new top end including some "fancy" Wiesco pistons.
Getting to the point, I have since heard that this triple is suseptable to overheating the center cylinder. I would like to hear any words of wisdom about how to treat these engines. What should I look/listen for? Should cylinder head temp sensors be installed? Before a take them out this year are there things I should look for? oil injection settings? Anything?
These being the first Polaris product I have ever owned I'd rather not make any stupid mistakes that could be avoided. Thanks for your input, I look forward to your replies.
