87_shee Posted February 12, 2007 Report Share Posted February 12, 2007 Hey guys.. Well I got my cylinders back and have been having some trouble getting everything to seal right. I had bought some cheap ass gaskets on ebay and I guess you get what you pay for, because they were junk every single one leaked, causing the motor to hydrolock after about 2 seconds. Also the rubber plugs were all F***ed up so I got some new ones along with some new yamaha gaskets and I cleaned all of the mating surfaces and put everything back together, torqed everything in increments to the specs in my clymers, started it up and its still leaking. When I started It, It was blowing out the Radiator overflow hose so i know its my head gasket not sealing right..but its also dripping a little bit from the base of the cylinders. So my question is could my head and cylinders be warped? If so what can I do about it? Does resurfacing with sand paper like it says in the clymer work? I seized a bearing on the crank in august but would that have caused things to warp? Sorry for the long post... i just want to get this thing fixed :: Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted February 12, 2007 Report Share Posted February 12, 2007 use a piece of wet sand paper with some water and rub the cylinders and the head on the paper in a figure 8 pattern till they are even. Quote Link to comment Share on other sites More sharing options...
87_shee Posted February 12, 2007 Author Report Share Posted February 12, 2007 use a piece of wet sand paper with some water and rub the cylinders and the head on the paper in a figure 8 pattern till they are even. What grit do you think i should use? Clymers say 600, i searched on here someone said use 240 grit.? Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted February 12, 2007 Report Share Posted February 12, 2007 I think you will be allright with 600, if it is warped real bad you can drop down to the 240, remember with sand paper the higher the number, the smoother it is. in other words the 240 will remove a whole lot more material at once compared to the 600.

Toybreaker Posted February 14, 2007 Report Share Posted February 14, 2007 Honestly, If you have never done this type of stuff before take it to your builder and have them blanchard grind it or mill it flat. Piece of mind. While you are at it take your bottom end in and have him check the base for flat as well. Quote Link to comment Share on other sites More sharing options...
