yamadoger Posted July 5, 2009 Author Share Posted July 5, 2009 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. Link to comment Share on other sites More sharing options...

oldtimer Posted July 6, 2009 Share Posted July 6, 2009 does any body on here know anything about these kits for old bikes and sleds,an info source ,specs,a link anything. please & thanx gyt kits have not been available over here since the sixties During the 1960's Yamaha supplied many so called GYT kits for many models, but when the "real" race-kit parts became available for the AS1 everything changed.so most people on here being younger would not have heard of them.they were more popular your side of the pond and were available longer,maybe some of the older guys your side might be able to help.

as2cafe Posted October 28, 2009 Share Posted October 28, 2009 The gyt kit was a factory upgrade kit that lasted till the early seventies. I know everything there is to know about the kits as far as twin streetbikes go but have no idea about the sleds. Link to comment Share on other sites More sharing options...
turrican64 Posted October 28, 2009 Share Posted October 28, 2009 I have the measurements to modify the existing cylinders and pistons, as well as the measurements to make the pipes from scratch for the old two stroke twins. What motor do you need it for specifically? If I have something, I can post it up. Link to comment Share on other sites More sharing options...
