DT125R FORUM

Happy new year to all,I wish you only good health, everything else can be gained more or less.

@Calum Thank you for the existence of the forum.

@SpookDog Turns out if you run 421 pitch chain on a bike putting out nearly 30+ ponies, it's really only good for a few ride outs.

Snapped 2 years ago, haven't ridden it since. Restoring it back to 520 pitch.

Was rapid though, probably did like 500 miles on a chain which was probably only designed to do a single race 😉

6Nm rings a bell 🤣 Haynes is invaluable.

Cheers @HOTSHOT-III. No me neither, but there seems to be some sort of cult following for this specific bike.

That's the saddle and they want £110 USED.

And the single speed frames seem to command decent money on the used market.

This one here is for £600!

Few teething issues just snagging the bike yesterday morning and then went to go ride the bike and came back to a flat tyre. Not sure if it was a defective inner tube as the puncture repair kit just melted the inner tube.

So I've ordered some more inner tubes and if I can be bothered could cycle over to Halfrauds and buy one so I can use it today.

The floating parts of the disc were fouling the bike/caliper so some minor adjustments needed and setting the chain tension etc. But it's basically there. Went around the block and I probably need to drop a few teeth on the front chain ring as I won't be doing any uphill cycling with it as it is. Fast on the flat though 😛

@ThatAnton Those Jasil/TopRacing crankshafts from PJME are excellent, trued and ready to fit and seem pretty good quality. I used one to rebuild my '93 without any real issues, TBH I only rode the bike a few times before selling it but the new owner seems very happy with it 12 months later.

They only fit the DTR but if you have a DTRe, a company in France makes a shim to get the flywheel in the right place:

@Hark_Ptooie I found with the Tecno expansion chamber (basically identical to the Athena) it fitted a lot easier using the genuine Yamaha rubber grommet and spacer on the upper mount. The ID of the spacer is quite large and allows a little more movement to line it up than the grommet/spacer supplied..

@Calum That site is known even more year's!!!!!
