    Question ???'s about 97 SL 1050 cylinders

    Mine are rated 81mm. Stamped 81-6R. What's the 6R mean??? The reason I'm asking is that I have to completly replace the #2 cylinder. Found one on Ebay, but it's rated 81-3R!!! Will it work fine when I finish the rebuild, or is this cylinder to small??? Thanks in advance for any insight.

    Is the actual part number the same? Should be ending in 009. I think those other numbers are part of the lot numbers or mold numbers.

    --Not sure. I'll have to look closer @ that. I'm sure it is though...ends in 009 rings a bell. The cylinder that I'm looking 2 buy came out of a 900...so I'm concerned. Don't wanna put two 1050 cylinders on w/ one 900. But my pistons are .075mm. I know that, and the two good cylinders are rated @ .081mm. The replacement I'm looking @ is also rated @ .081mm, only that 6R vs. 3R crap is what I don't get!

    --I guess a better ? would be this: Will this cylinder work normal on an SL 1050 engine, with two other 1050 cylinders??? This would be a replacement for the number two cylinder on my 1050.

    Your link is no good.

    1050 cylinders have a 81mm standard bore

    900 cylinders have a 74.5mm standard bore

    If your cylinders are 75mm then you have a 900 not a 1050.

    Sorry, it cut half the link off on me! I know what the bores are. I have a 1050 w/ two good cylinders. Bored up to 81mm. That's stock polaris cylinders for that model. I need to replace the third (#2, middle cylinder). My question is in regards to this cylinder listed on ebay. Will it work? According to his numbers...it looks like it will, but I'm not sure...that's why I threw the link up here. I'm hoping someone w/ cylinder knowledge will know.

    If you have original 1050 cylinders on your '97, they are 009 part numbers...that one on Ebay is an 081, which has different port timing. Can't remember what rpm the 081s ran off hand. I'll try to find my notes

    So it won't work at all? You are right...my 1050 has 009 serial numbers! I just need to know what you answered and I already thought! Thanks!
