could any one post up a service manual page on installing the kicker gear in a 78 dt 400. I can not seem to get it to wind up correctly and don't have a book for it. thanks

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.

I think it would be great, there is nothing out there for Yamaha sleds especially vintage sleds. This may not be a big deal for some people, but here in Minnesota and the great north woods we get snow. It would get used believe you me. THANKs tO All

i am looking for an original green & white 69-71 ct1 gas tank, dings dents and some rust are good things. i am in the u.s. E-MAIL ME @ [email protected]

ok so i got the 70.5 mm from wiseco, this way i can hone it out and make sure it gets a nice cross hatch. wow these are spendy

check to see if your compression is getting low

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 .

wow you fellas come up with some wacky stuff over there.

wow you guys come up with some pretty wacky stuff over there.

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???????

can u believe this kids asking price. sorry i meant copperhead road. who ever gets this bike may get the pleasure of seeing their rear wheel pass them on the freeway some day.

i have noticed over time that these old yamaha bikes just kinda evolve from one another.in a way i always thought of the as the small block chevy of motorcycles. but i don't like chevy...........GIVE ME TWO WHEELS OR GIVE ME DEATH.

thanx foamy, that was my first thought . was wondering if any body had done a head swap on these before,as i hear they are hard to find

Hi all, was wondering if anyone knows of other heads that will fit my 69 ct1 175, have a mess of old dt 175 parts 74-76 era but haven't checked them yet. keep on yamadoggin

[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

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!

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.

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

nobama

this on tv...... i think so played anytime someone mentions thriller

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

so 30 pounds wont work....?lol turns ot its ten thou undersize i was a little suspicious when the jug slid on so easily

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.

For dirt the yz 400 78 give it a twist and let er buck weeeeeeeeeeeeeeeeeeeeeee. For the road a race gas rd 350 with some good pirelli tires is almost too much fun, especially when embarrassing honda cbr's
