My exhaust blew up! PICS

Sounds like a blessing in disguise to me. All works out right, and you'll be enjoying some extra power!

Keith helped me out in another thread. Stock jets are 95 and 15. I now have the yosh pipe installed and the 117.5 mains in. Seems to run ok. I'll give it a good thrashing tomorrow and if it doesn't blow up I'll check the plugs and see what they have to say.

BTW: My patch lasted 50KM's. 8-[

OK The main jets in the donor bike are all marked with an "R" then a small square in a larger square, 117.5.

The pilot jets are marked with the same double square thing and 15. They are the same across the rack.

BUT WHAT DOES IT ALL MEAN????

The carbs loof stock. There was no airbox. I'm thinking the PO likely rejet it or it wouldn't run worth sh!t.


What is stock jetting on a 78 GS1000? I'll compare that to what's in the donor bike carbs. I can't use the donor carbs. They were smashed in when I got it.

thats what i thought, looked like a old yosh pipe. Get that pipe cleaned up, and tear that motor apart lets see what you got in her? How about the carbs they stock or after market?

OK! I think I got it. Pics to follow.

Canadian Tire muffler repair kit, cans, hose clamps. I think it'll work for a bit anyway.

I still think I'll get the crapper 4-1 ready. just in case.

What is the stock jetting on my bike? I'll see what's in the donor bike. Maybe it was jetted right...[-o<

Until I could replace it with a V&H, I would cut up a half dozen aluminum soda cans, buy a couple of large hose clamps from the auto parts store and wrap the split with the soda cans and clamp them with the hose clamps. Just wrap about 4 layers of soda can around it. It should hold until you can get a replacement.

So c'mon guys! What do you reccomend?

you could simply order a Jama replacement through your local parts can dealer or thiebault dealer. Should cost you all of $90 plus gst of course.

You can get a stainless band clamp at an exhaust shop, or a truck shop,( they are made for truck exhaust) they cost about 10 bucks, 3.5 or 4 inch diameter, if it is too big they can be shortened, they are about 3 inches long and should patch that mess up nicely for now.

I like this idea.

No re-jetting required.

just use the pipe on the doner, looks kind of like a old yosh pipe? got any better pictures of end of the pipes, bythe painted over badge in the back? should be stamped metal with a brand on it.

worst case like everyone said tape it up while doing that get that other pipe sand blasted and painted with rustolemoum 2100 grill paint.

and check the carbs to see what kind of jets are in it.

start digging into the donor, may it has some good things, it's kind of like x-mas when you get something like that.

Muffler cement or furnace cement with a well placed piece of sheet metal pop riveted on as a temporary fix

I like this idea.
