A tyre/rim chart I have says up to 80/90-21 is ok,90/90-21 is what I will put when I change tyres.
Don't remember where but someone fitted that size to 1.60-21 rim and had no problem.

@GiannisT No worries 👍 The XT springs/15W oil mod stiffens up the front end quite a bit, to make my YSS shock match the forks I had to up the preload 16mm over the supplied setting and run the rebound on position 29 out of 30. If I'm honest it made the suspension a bit too stiff for off-road (I weigh 145lbs), if I'd had more time I would have experimented with cutting 10mm at a time off the DTR spring spacers to get it just right.

I had Michelin Trackers (road legal MX tyres) fitted all the time I ran this setup so can't comment on street use but it's a pretty easy mod to try and it sounds like you're looking for a stiffer front end, XT springs come up for sale quite a lot because a lot of owners upgrade them (too soft for the 160kg+ XT = a good match for the DTR). Would be interested to hear if it's good for Supermoto, plus if you still want to go the USD route it won't have cost you much to try it!

@HOTSHOT-III Cheers buddy yes that's the thing - the box is in good nick, I just ripped the lock tab off. I could try and make something up, but it'd be a shame as the bike's currently all original/unrestored.

Thanks again!

Shaun.

Well, nuts and bolts are standard across industry, so you don't need some special kit.

I go to my local hardware store where they have open packs of all sorts and sizes. You put them in a bag and weigh the bag and pay per kilo.

Most screws I have swapped so far have been M6x12 or M6x20 with some odd M5 and M8 here and there. I usually get flanged screws and skip the washers.

I do so love screws. Then again, I am a mechanical engineer so the fetishism comes with the profession. If you want to talk screws joints for a couple of hours, I'm your guy.

87 miles...Yeah it'll do that no problem. DTRs are a work horse. 15 years and mine has never let me down.

@SpookDog it's not a bad thing in my opinion as the 88 black with red is my favourite colour. I do like the endurance blue but the black and red just cuts it for me.

The Imgur app can be used just on your iPhone, upload to an Imgur site thread, then copy the link of the individual pic and put it into the  option 2nd from the right in the toolbar above that is visible when posting to a thread…

@primal-carnage

If it comes on ‘a bit’ it may be a bad earth at the tail light. Is it the same with back and front brake levers?
Also have you changed to LED lights anywhere?

The brake light should work off of the battery without the engine running…

@HOTSHOT-III yes that is my video. I should also note, according to this my bike is actually a 1990 (the black and green one), although they might not be the original panels. I think its a 3RN2 model, the one they sold in the UK with the servo removed.

@Calum and of course Japan kept the cooler ones to themselves haha

When I bought my 2002 dt125r it had a few apico bits on it and one of them was a gear change lever I was told that all the bits were from a yz125

@old-boy-racer Hi there,

Zeeltronic is just about the best bang for buck you can get in my opinion. Of course this depends on what model/year/location DTR you've got.

It's all diminishing returns though, once you've got a decent exhaust and the zeel, everything else is just marginal gains.

Earlier this year I fitted the VForce4 Reed block to my Yamaha.

The Athena 170 kit is not a bad upgrade too if you're after a bit more midrange poke.

@Scootjockey You're laughing then. It should be the 1993 TZR 4DL Belgarda.

@Scootjockey Thanks bud 👍 That adaptor is the correct size for the DTR main bearings and crankcases but potentially you could have one made for any engine. Mine was done by a local machine shop.

Even when you watch the Rocky Mountain ATVMC how-to vid where the crank puller is branded "Tusk" for the US market they still transmit a side load through the bearing and lots of people have commented on it

@H22dan
Hi Dan a Q plate bike will never make as much money if your doing it up, least not one on a standard reg plate due to the stigma of possibly being stolen and recovered. Years ago a mate of mine bought a Suzuki X7 from the insurance company/ police sales it was stolen and recovered and all the numbers had been ground off. The feds identified the bike allegedly by x raying the frame. And the insurance company paid out on it. He new all the old numbers and owner etc but it couldn’t be put back on the road with those numbers or the reg plate. So he then stamped his door number and post code on the casings and frame and registered it with DVLA once it was MOTd. Showing my age now but back in the early 80’s a Q plate was rather popular what with all the 250-350lc’s making it on the tracks for production racing and then being put back on the road. With that in mind they are a lot of trikes out there on Q plates that were home built with the back end of a VW Beetle. All legit just the front end will have numbers from a chopped up bike and not match.

@Scootjockey I ran vapor trail digital clocks, but not because of the Zeel, but because I swapped out the forks and wheels for USDs and Aprilia RS 125 wheels respectively.

@theportingmaster I mean, it's 20 years old so I wouldn't be too worried if it's not concourse. Espcially if you want to use the bike daily etc.
