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

size is usually stamped on the front top. nothing there means standard bore

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.

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
