the 1972 gyt kit had a pipe to fit the '72 chassis. It also happens to fit on the '73, as well as a '74 sno jet sst of all things.
 
Is their a different track you can install on this? Can you remove the center drive and go with dual drivers?
 
I think the drives from the newer models may fit with some work (GS, etc)
I investigated this after losing the original track, but luckily I found a NOS aftermarket track.
If I remember correctly, the 58 hole bombardier track was a reasonable alternative in width, length, and overall size.
 
Mine looked like new too, then it decided to come apart when I was beside it. My leg didn't look so great for a month or two!
 
my dad lost 2 of those tracks on a 1975 gs338 under warrenty on his way into camp with the sled. 2 tracks in one season is just plain bad and he was running them on a cleared packed trail at the time.
 
I took both my GP292's (1 open mod & 1 stock) and converted them to 2.25 enticer tracks. I had to run boggie suspension, so I cut the boggies to roll inside the track lugs (drivers). Then I used 7 tooth enticer drivers pined to the GP's drive shaft. Next I also put a set of drivers on the rear alxels as well to help keep the track straight. No problems with the stock sled, But I did have problems with my open mod sled de-railing the rear axle.
It can be done if you have the time
 
Yamaha definately made a GYT kit for the full size GP292 ( the one you have )
They also made a high profile track back then too.
The GYT kit that I remember had a different cylinder, piston, rings, and head, gaskets, carburetor, ram tube, and clutch parts..there was a shim/spacer for the primary. We had two different style pipes, one wrapped around neatly under the hood, and the other ran along the right side and exited by your right foot. Were you going to keep that stock GP292 motor or were you going to build a race motor for it such as the free air versions in the SR292?
 
Yeah I suppose in that class it wouldn't make that big a difference. So if a guy showed up with a 72 with a later model slide rail suspension they would bump you into the mod stock? Same with the GYT kit I imagine?

Monty, your avatar is an SS 396, correct? The driver looks really experienced, not too sure about the passenger though. lol G.
 
Hey, I was just looking at the pics above and noticed the size of the brake! Its nearly double the size of the one on my 77 GS 340. I'm curious if this would swap into my GS? I realize that the entire brake pad assembly and possibly even the chaincase would probably have to go as well. Mine of course has that odd dished disc, so the levers for the pads most likely wouldn't work, but if it were to be a fairly simple swap, it'd be an easy way to improve the braking on the old GS. Can you tell me the diameter of that disc please? Thanks. G.

yes that is a ss396. Dad giving my my 1st ride!!! after I started racing 4 years ago, dad told me that it was a pretty wild ride back in the day. Mom made him sell it as it was too "loud" for my little ears
 
Cool history. Yeah, they were loud, probably didn't ingratiate them with a lot of people. One day a neighbor called my Mom and threated to shoot me on my SS 433 if I rode past his place again. Must drove him nuts as I was past there all the time. lol. G.
