à VEE RUBBER was on the Beta I bought this summer and I did not like the traction so, I bought à Dunlop 803 GP. The Price was reasonable. Guy

Speaking of lube, what do you use as a cable lubricant? Guy

The Universal Venhill might be a good idea for the clutch cable since I modified the frame ( motor raised ) and also modified the clutch actuator. John, do you use the universal kit for the front brake too ? Guy

Both front brake and clutch cables need replacing on my Ty 250 1975. I was thinking Venhill but I read somewhere that there might be some issue with the length of the clutch cable. Any comments or recommendations ? Guy

Tank's lot for the advise Guy

A few friends got into trial riding not trial competition and bought 2000 to 2007 modern trial bike so I decided to try one myself, I bought a Beta Rev 250 2003 last July. I still am a little shy to go to our twin shock friendly competition and bring the Beta alongside my TY because of the look you get from '' real '' trial riders. I am so glad to see that there are clear-sighted riders around. Yes to all that was written above: the weight, the power, the balance, the brake, the transmission and so on. Don't get me wrong, I enjoy riding my TY as I would like to ride Bantam or a rigid frame trial bike, but modern trial bike are a delight to ride. I needed some parts for the Beta and the dealer offered me to have a go on a bran new TRS 300, yes they are better than my 2003, it took me 30 second to notice that. Someone told me: you bought a POGO STICK., no I bought a 2003 Beta REV 250 and it's a lot of fun to ride. I also was born in the 50s so maybe I am wise enough to appreciate the old and the new... bike. Guy

When I'm done with the installation of the tube type ( either Michelin or IRC ) I inflate it at 30 or 35 psi and let it rest for a couple of days, is it the way to go with tubeless ? Guy

Got home tonight with a new rear Dunlop 803GP in the trunk off the car. The plan is not to leave it there, so, again I need advice. I never change a tubeless tire on a moto. Looking at YouTube file, they make it look easier than Harry Potter would do it with a flick of is wand. I change a lot off tube type tire, any thing I should be aware off. Guy

Right on with the details David. When I have a rebore done on one of my TY with Yamaha piston , I usually ask for a .002 inch clearance and I do the running in over 2 days : first morning, start and run for about 30 sec, and in the afternoon, start and run until I can feel the heat on the cyl., let it cool and repeat. The next day I repeat but i run it longer. I know it's over over overkill but I had one done ever 10 years ago that has not started to rattle yet. Guy

Where are you in Canada ? Guy

I tried a new pair of Forma Boulder, just perfect for me. Guy

What should I use as the coolant in my 2003 Rev 250 ? Guy

Just back from a ride this morning. Thank's to Jimmyl that was not so bad, at 3.5 psi in the VEE it's much better but the plan to change it over the winter is still on, the front Dunlop is also better at 5psi. I checked the price of the rear Michelin vs the IRC, there is a big difference. Is the difference between the 2 in performance as big as the price diff.? Guy

I'll check the boxes just in case. Guy

I'm quite sure I have that in one of the box, but I'm in Canada so shipping would not be cheap, but the price would be. Look at what you can find in your neck of the wood and keep me posted. Guy

Where are you located ? Guy

The VEE was not free but on the bike when I bought it. The plan is to replace it this winter for a Michelin as they are more common around here if I decide to keep the bike .So I will try it at 3.5psi the next ride. What about the Dunlop front, it too proved to be.. what is the word ho yea '' scary '' at time 5.5psi ok ? Guy

I'm just back from a ride on my 03 rev and found out it did not have the traction I wanted. The first few rides on it ( purchase recently ) where great, no traction issue, today the mountain I go was a little '' greasy '' and I did not like the feel of the bike. I know the tubless Vee Rubber on the rear is not the greatest, but I think my lack of knowledge is the first problem. I ride TS with tube type Michelin front and back at 5.5psi fr and 3.5 to 4 psi back and rear IRC at 5.5psi. I rode this morning with 5.5 front in the Dunlop and 4.5 in the Vee Rubber. By how much was I off ? Guy

I had the same problem from time to time with my B model ( std Mikuni carb. ), I tried playing with the needle eight, main jet etc. . I change the pilot jet to a #40 and it did made it a lot better. Guy

The dealer are mostly '' reseller '' I don't they have that kind of part in stock, I '' googled '' the part number without luck. Guy

Copemech, you started my day laughing and feeling stupid ( still laughing ) I want to find out if there is any mudguard avalable to replace the one on my bike if it break. Since I live in Canada, spare are rare. Sorry It was clear in my mind, definitely not on paper. Guy

What is the best and easiest way to replace a 250 rev 2003 rear mudguard ? Guy

I really like the way you can '' tune '' the TY 250 motor with the different model parts. I build a test motor that I setup in a standard 434 frame and tested it with the same suspension, brake, tire ect. It is easy to transform one from a diesel kind of power band to an enduro type of power. BUT I think the transmission is it's weak point, not the reliability but gear spacing. Also it's a wide and heavy motor. Don't get me wrong, I won't trade or sell my TY tomorrow, when you ride one for a while you get use to that, another great plus for the Yamaha: parts. Guy

Back in the days... Yes I am that old, the brake where made to slow your bike down to a complete stop, if you where brillant enough to judge the speed you where going in comparaison to the point you aimed for that complete stop. Now, I can understand that one wish to make old drum brake as good as new disk one, but, experience say's that the more effective you make those drum brake, the less time they work that good. I wish I would know why. Guy

Do you mean side play ? Guy
