  1. if i'm understanding you correctly, the rubber bushings are most likely to blame. Try and get the part # from yamaha and check to see if you can get them anymore.

    you could always solid mount them but it will chatter your teeth.

  2. my mic says its 70mm,and the mic doesn't lie. The thing is the piston in it now appears to have about 10thousanth slap on the skirt end, and on the top. So i cant help but think this was never the right piston in the first place. Also when i got this bike i tore the top end off only to find the piston in backwards B) .

  3. well my cylinder is 70mm bore but the piston is stamped 0.50mm and the #1 or 4 followed by 52p2 is stamped at the top. I have sent for a new 70mm piston, but wanted to know were this other piston is from. any ideas??????? :blink:

  4. [thanks for your input i was looking through my old parts manual and this kit was mentioned, i was interested in the expansion pipe specs for an old race sled i am building. young people can know about the old stuff too, i am 23,got my first yamaha when i was 10, an old gp292

  5. wow i thought i didnt know much about these parts, i have to say I'm disapointed there are so many yamaha fans,and so little info!

  6. has no one ever heard of the yamaha factory perfomance kit, the GYT kit was available from the dealer when you bought your bike or snowmobile. This kit included tuned pipes, carbs, clutch set, a complete top end with bigger ports and more compression.

  7. I have a lot of 70-78 yamaha sleds 292-433. I am hoping for info on any gyt kits for any of these old sleds,or for older bikes like the dt,rd,yz all mid to late 70's ,and especially for a 69 ct-1

  8. does any body on here know anything about these kits for old bikes and sleds,an info source ,specs,a link anything.

    please & thanx

  9. :angry: when i got this bike i tore down the top end, only to find the piston in backwards and a very shoty base gasket .

    after looking closely and picking alot of old gasket material out of the oil journals and transfer ports i reassembled with new base gasket. and it still wont so much as fire. I also cycled through the timing and not a sputter. does anyone know about what these should have for compression.
