    Hi Spookdog. The bikes a 1991 French import, cheers for the info about the screws. It looks all original, I've had it about 3yrs but recently started the top end. Took the cylinder to a local bike engineers who bore and fit a new piston, the original was 56mm its now been bored to 57mm but the piston seems sloppy in the barrel, can get a larger feeler down than speck....not good! Its bound to slap if over sized!? Whats your thoughts, its not back together yet.

      It’ll slap and get worse quickly, well it has in my experience.
      Piston should be tight in the bore. The only place I would get a rebore done now would be a reputable one. I use PJME because I heard nothing but good about them and the finish is excellent. I used a local engineer to get a barrel honed and it came back looking like it was raped by a Brillo pad!..

      If it’s as bad as you say I’d take it back to be fixed. You paid for a service you should be happy with.
      Can you post pics of the finish in the barrel? If the it’s that bad I’m concerned about the hatching and the port skirting

        Hi all. Just want to say hello and its nice to be to a newbie on the site. I've owned my DT125R for about three years now, its a French import now on a 1991 UK plate. I had a look around it when I first got it and it now has 9000 km on the clock. I was suprised to see electric start on such a early model with the electrics wedged into the LH outer casing. Since getting it I found out it was burning gear oil from the RH clutch side so I replaced the crank seal on that side, the hardest part was getting those 2 screws off the baffle plate and the bigger screw holding down the seal plate...RED locktight solid 😭 👎 I hope to learn more about the bike through the forum, it needs a top end build.

              Download Imgur and use it to post/host the pic. Then copy the link and post it here using the 3rd icon from left in the toolbar…

                                        Yeah the chain snails look smart, you can get aluminium ones on eBay for very little money. Needs the internal diameter reaming out mind you.

                                          Hi the honing looks not bad, having to reduce the quality of picture loses the clarity a lot.
