razorbackbanshee Posted February 4, 2013 Report Posted February 4, 2013 Hey guys I've always been a banshee guy (I've got two) but I picked up a near mint 1992 LT250R the other day, and I'm hoping some of you have some background with them. I bought it cheap because compression was low so I'm trying to get it rebuilt. I took it to the local dealership to get bored out, but when they miked it they said that it was 69mm. Stock bore on a '92 is 67 so they said they didn't think they could get a piston that big. So I think it is .080 oversize and unfortunetly that is the last size that I can find. Does any one know what my options are? Would a RM250 Piston work? Or maybe a 70mm piston from a 85-86 LT250r? My last resort would be to resleeve it, which I would do because it has a lot of nice port work, and is also completely polished. But, the cylinder bore looks great with no marks, the reason it failed was the rings froze in the piston grooves Quote
razorbackbanshee Posted February 4, 2013 Author Report Posted February 4, 2013 Thanks for the reply. Yes, I was just planning on getting it honed. Whats your opinion on boring it out to a 70mm and putting in a '85 piston in? Would that match up, or is there a difference because of the power valve? Quote
razorbackbanshee Posted February 4, 2013 Author Report Posted February 4, 2013 Yea I was afraid of that! Do you have to bore the stock sleeve out or will it press out? Whats a ball park figure for someone to resleeve it? Quote
sheerider11 Posted February 4, 2013 Report Posted February 4, 2013 Just shell out the coin and get it plated at power seal Quote
