Ficky Posted September 20, 2010 Posted September 20, 2010 Hi Team I have just pulled down the xs motor and wish to know if the markings under the skert mean anything (3 & 4 ) are this size if so do we know the size needs bore done so looking at size ? any help would be good Cheers Chris

saltcreekknife Posted September 21, 2010 Posted September 21, 2010 Hi Team I have just pulled down the xs motor and wish to know if the markings under the skert mean anything (3 & 4 ) are this size if so do we know the size needs bore done so looking at size ? any help would be good Cheers Chris I just put a new piston in my dt175. There were no markings relating to size on piston I took out. I had to measure with a caliper. Once you have the size you can look up if it is standard, oversize, etc. If you have a shop in mind that is doing the re-bore, they would probably measure for you if you do not have caliper. Good luck.
Ficky Posted September 29, 2010 Author Posted September 29, 2010 Hi Team I have messured the piston and yes they are standard, so have ordered 2 new .25 oversize pistons and rings will send bore in soon for rebore . Thanks for the help
