Where can I get a piston for a 198a bultaco it has a bore of 71mm. Thanking you in advance. Hightown

The later 250 ('76 on) was sleeved down from the original 244cc 72mm standard bore to 238cc 70mm standard bore. You can still use the original size 250 pistons that start at 72mm standard and there are 4 oversizes, so you won't run out of 'meat' on your liner. So you aren't limited to a 71mm piston
