TY250C resto questions

[Guy53]

Hello Greg. You just opened a box of crab here, I am preparing a modified TY D frame for this summer ( Canada ) and I was going to put TY B wheels ( front and back ) on the bike, I never noticed that there was such a difference between the rims of an A model and the other. I was able to get from my dealer a set of tube type Michelin. I have a few sets of A model wheels, now I wonder should I use the larger rims or the narrower ? What's your input ( and the other readers as well ) on that ? I never paid to much attention on that but now you got me thinking.

Hi Everyone,

Guy53, Suppose it comes down to wether you want an original bike or one that works better with less hassle, if as you say a modified "D" model, then the latter. Me personally, always go with the rims that hold readily available tyres, on TY twinshocks "A" model rears and 175 fronts for the same reason, this is what is on my TY Challenge bike, seems to work for me!

Did not mean to confuse the issue, just being honest!

I like the look of the C and D model TY250 rims, they are very light and I seem to be able to get rear IRCs when I need them so I haven't needed to fit different rims.
I find that IRCs fit well on shouldered Akronts, shoulderless Akronts, KT250, TY250A, TY175B, TY250B and TY250D rear rims

Just got off the phone with the IRC importer - they are out of stock of IRC rear tube type trials tyres and cannot say when they will be back in stock. They have not submitted an order through for more. If they did order, they would have to sell them for more than a Michelin due to various economic factors. I asked if they would be in stock in 3 months and was told unlikely and nothing will be ordered for a while from IRC.
An IRC was going to be my saviour, but looks like I'll be collecting the Michelins tomorrow.
It also looks like I may have to go the wheel builder route. I really didnt want to go custom due to the $$$ involved (quoted approx $600 for a rear build), but availability of decent tyres will dictate what has to be done.

[Guy53]

Is there a difference in hadling ( grip ) between the different rims, I remember that on road racer, dirt tracker and ice racer there was a sometime big difference between a narrower rim and a wider one. Anyone tried the same make of tire with different rims.

Why not just fit a Tubliss to your stock rim? There is then no need to go to the expense of a tubeless rim (which will be difficult to find new), and you will be able to run either tubed or tubeless tyres no problem at all. http://tubliss.com/

FM350 - thank-you for the information, this tubliss system looks SPOT ON -I had never seen this system until today
I have spent a bit of time researching it today, and it appears they can be run with trials tyres to 5psi, and act as a 360 degree rim lock so the tyre wont have a chance to burst off the rim. I havent read any testimonials from trials riders, but everyone using the system remarks on how well their tyres work and how at low psi or even flat how the tyres wont fold off.

Thank-you FM350 - this may change everything (again) !

[FM350]

Not fitted the one I have yet, but several trials riders in the UK have been using them with no problems at all. Seems a very good way of allowing use of tubeless tyres on pretty much any bike.

Quick update on the "B" -progress is a lot slower than I thought!
-I re-cut all the threads on the frame on the easter weekend
-colour sanded the original tank and shot a coat of clear over it (looks a little dodgy, but looks a lot better than an untouched 40 year old tank)
-Cleaned up the air box and found some new bolts for it.
-polished the triple clamps up on the buffing wheel and replaced two threads on the clamp holder with "timeserts" as two bolts broke
-new steering bearings fitted with new bearing covers and top adjuster nut
-fitted the new Sammy Miller footpegs and mounts (had to machine up 2 stainless spacers as they would not bolt up "true" to the frame)
-I dropped the wheel hubs and magnesium backing plates to Greg who runs "Hydroblast" in Moorabbin, they should be ready for collection early next week

Swingarms currently on the workbench - machining up parts to make the chain guide "as new" (chain guide mount was out of round)
Bought all new swingarm bushes / shims / end caps, so hopefully will have a restored swingarm back on the frame by end of weekend

QUESTION for the day: anyone know of any web based stores that sell Falcon shocks apart from Falcon themselves? Anyone had any luck with Rockshocks rear shocks ? I need to order shocks soon, and have decided one of these two brands seem the better picks, Rockshocks seem easy enough to get, cant seem to find anyone who sells Falcons, and the local distributor appears to be selling them for double the recommended list price...

[FM350]

Falcon will sell you shocks direct, and even with shipping from UK I think they will cost less than if you buy from Aus dealer. They work better than Rock-Shocks or Magicals, and are the ones to have if you want to ride in competition.
