I need a new rod kit for my TY 250 1977 ( Canada ), I think all TS TY250 can use the same connecting rod. Does anybody know the part number for Hot Rod, IMS , ProX or other rod kit that would fit my TY ?
I normaly use genuine pads but the last set I bought where not ( i'd have to look if I still have the box to tell you witch yhey where ), and I did the same thing : as wide and deep and no problem up to now. Winter is comming so it's time to make an overall, I will take a good look if they seem to be deteriorating.
Yes, but the heavier the the flyweel the slower the response on and off throttle, and you have to consider the position of the weight: the further out the more effect it as on the motor. With the heavy TY B flyweel, the throttle response is slow and it seem's to take forever to get down to idle speed. I think I have a picture off the A and B flywheel, I will try to find it and post it.
David, I will keep your advice in mind. I should be able to make a good test ride this week end, so I will be alert to stalling. I have an unmodified A model apart my heavy B model flywheel so if the bike have a " stalling tendency " , I will go back to a standart weight A model flyweel and see if the rider isn't the cause of the bike behavior. I also try to ride without the clutch.
I don't know about the rest of the world, but here in Canada, the B model was sold in 1975 and the weight added to the flywheel is twice as thick and larger than than A model. I run a weightless A flywheel on my B , and I went for 3.4mm advance. the bike start and run well ( in the backyard ) but I did not have the chance to try it properly. If I went wrong, don't be affraid to point it out, I would be happy to read your input.
I know I read it somewhere but I did not find it: I am installing new points and condenser on my TY B, I normaly set them to 3.1mm BTDC as per my Yamaha service manual ( A model ) but I remember that many don't set them at that BTDC. What is your input on that ?
They are standard TY A rods, many modif can be done, I went for cartridge emulaor. I like them, but I am sure that some other owners will give you cheaper tips.
I David, do you run your modified TY with a very soft front end ? At first I ran a harder setup and was alsways in trrouble in rocky sections. Since I installed the cartridge emulator and set them up so they are very soft, it is a lot easier to ride the rocky sections, but at the same time, I noticed that with a little more weight on the front end, the steering was better in moderate climb. Maybe half or tree quater of an inch longer swingarm would make it better.
I gess it as, but, with the footrest lowered, it as to compensate. Plus the change of the position of the top shock mount and there lenght also change the fork rake witch make it, in my opinion ( might not be the best ) easier to ride. I live in Québec, no other Ty that I know were modified to these specs, but I still have a standard TY and even if I am NOT an expert ( lot of weight on the NOT ) I can tell you as I commented in an other post : yes it's worth the trouble to make the mod.
