Question about Yamaha DT 125 RE Motorcycles
Howdy.if your bike is a two stroke the ring has a pin in the piston groove to stop the ring turning.on four strokes the ring gap should be off set to each other and generally placed between 20-25 past and 25-20 to [like a clock] but no where near the side of piston at little end pin.also use a little oil in grooves to lubricate while fitting rings.some rings have angled edges so check wether they go top or bottom directions in manual or packaging with new ring sets.most rings will be marked to guide you.have fun and good luck.cheers

Testimonial: "thank you so much for ur advice, it really helped and now my pistons are in. but my bike will still not start. do you know of any other reason for it "
Hi mate the yamaha dt125 does have small lugs in the grooves of the piston if they are not there it just means that the piston is not genuine yamaha just make sure the gap in the piston rings are opposite each other ie if you have 2 piston rings the gap in the piston rings are at 180% to each other if you have 3 piston rings they the gap in the piston rings are as follows, bottom ring the gap at the rear ie: 6 oclock middle rings at 2 oclock top ring at 10 oclock that will keep up the compression
