I have just bought a tdr 250 off of Ebay tonight and would like to know if anyone has any experience of owning one,common problems and things to check. I have owned a lot of two strokes but i have no experience with these. I know they use the same engine as the tzr250 ypvs,but thats about it.

Any help would be appreciated.

first thing to do is strip the powervalve and make sure its not sticking or siezed, then buy it some DEP pipes and have fun.

Wheels size will limit ya choice of "sticky" tyres (TZR 250 wheels can be made to fit easily) and the two stroke oil filler is a pig (start collecting business card, rip off two corners and make yourself a disposable filler - my boss never worked out why I went through so many cards

)

thanks, i'll check the power valves and look for some Dep pipes. I'am trying to buy a set of tzr250 wheels with new Bridgestones for £140, just waiting for a reply.

TZR wheels don't improve the choice that much nowadays. The rear is the same size as the TDR and the front is the same width only 17" rather than 18". Or were you talking about an exotic TZR rather than the TDR stablemate?

I've had a set of TDR hubs relaced in common motard sizes, 17x3.5" front and 17x4.25" rear. Which was in retrospect a dumb idea even if they do look cool. Chain clearance is a problem and despite spacing both sprockets out I can't sort it. I think I'm going to have to buy a 140 section rear to replace the 150 that's on there. I did try shaving the tyre but I had to shave so much off I wasn't happy with it. I've got some standard wheels but they're quite crappy and I don't fancy using them they're so corroded.

If you do go down the 17" front route, the speedo drive from an early FZR600 Genesis goes straight in and keeps things reading true. Oh and 6-pots off YZF750s bolt straight on. As do floating Brembo disks for 916s.

Shame this all just ends up being an ornament, finishing my TDR off has been on my to-do list for several years now. When my lodger goes I might have some space to work on it.

I had one years ago and did the TDR fun cup on it.

The rear wheels are prone to breaking spokes so keep an eye on the tension. Tho most would have been sorted by now.

They are also prone to cold seizures so make sure that they are fully warmed up before you go caning the engine.

Did you buy that blue one off of ebay that was .75 overbored????

It maybe worth while taking the zorsts off and getting the caustic soda out and giving them a good clearout. Dep pipes work great on them too.

Use a quality 2-stroke oil, some peeps ditch the auto-lube system and go for pre-mix incase the auto-lub pump packs up.

I had a TZR250, which is the same engine. Nothing to report other than the usual horror stories of 2 strokes

Mine, blew up on the way to Box Hill. Turns out that whoever had owned it b4 me had also blown it up and then put pistons in that were bigger than the barrels

My Oil pump then packed up, so went for pre mix instead. Mine ended up about a 275 in the end and I fookin loved it to bits, even thou it was a pain in the arse. Got all misty eyed over a RGV for sale the other day, would love another 2 smoke

If they're the 2.15/2.5" early TZR rims those are _way_ oversize...

...although I think the rear got slightly wider on later models. I suspect they're actually wheels off something else, perhaps an import TZR. Not that it matters where they came from if they work.

Worst thing i ever did was trading in my second TDR in on a DUCATI 916, the 916 was good fun but the TDR was better. TDR250 is in my top three bikes of all time.
please dont put TZR wheels in it, they look shite!

The front is mt 2.15 by 17 & the rear mt 2.5 by 17. So they wont fit on my bike

No, I was saying those tyre sizes you quoted seemed far too big for those wheels. I've a 130 on my standard TDR rear wheel (same size) and that's oversize, I'd have thought a 140 would be distorted.

Likewise the front, you're squeezing a tyre made for a 3-3.5" rim onto one that 2.15" wide.

Assuming of course there's no confusion over tyre/wheel sizes mentioned.

Sorry i get it now,I think i'll leave them alone then.

I should probarbly try riding the bike for a few weeks before changing the wheels.

Might make sense. Welcome to the 'retromotard' club by the way. Anybody got a good Nordwest for sale.

Oh yeah I forgot to mention it. I have a TDR250 workshop manual fiche and parts fiche.

I had them professionally scanned but they are in very poor condition so the results look awful, but they are at least legible.

If you need the manual I could package this up into some kind of sensible format for you. At present it's a monstrous multipage TIFF.

I've been meaning to clean it up and make a PDF for ages.

The bloke who i'am buying the bike from said he had downloaded a manual off the internet,so i'll see what that looks like first.

I missed out on a 95 m-reg Nordwest,f.s.h. low miles Arrow pipe in excellent condition for £750 o.n.o in Bike Trader issue 18th-31st january

Might be a TZR manual they are definitely around on the Internet. I've not seen a TDR one, if it is good I'd quite like to grab a copy or find out where it was from.
