Hey,
A few years back my '94 SLT 750 laid down on me. I tore into it and found a hole in the number three cylinder piston. I got the parts I needed and rebuilt the cylinder myself. I talked to a guy in Louisville who is a pretty good PWC mechanic and he said the problem was due to that particular cylinder running too lean, which to me made sense. I took it to him and he got some carb rebuild kits, installed them and dialed them in. The ski ran great. THis was like 1996 I believe. Well, recently I was doing a little maintenance and decided to pull the heads and check the pistons. Unfortunately for me, the number three piston has a lot of pitting. I don't know how close it is to actually burning through, but I don't believe it is far off. I have heard this is fairly common with the 750 triple and would like to know if anyone out there has a good remedy for this. It looks like to me that maybe since this cylinder is the farthest from the fuel tank that maybe it is continuously starved for fuel. That's just a guess, but it is the best guess I have at this point. If anyone has any info, please pass it on to me...thanks
