Copper exhaust donuts

[Tuesday]

I cant find that thread on those copper donuts, anyone have a link? Yammi wants 21 per gasket, looking at options.

 

[SNAFU]

I am not sure if it is the exact thread your are talking about, but I remember seeing a picture of them in Tarzannr1's Pimp my Nytro Thread. Zipperno is the one who sells them and I think he is in Norway. I am not sure if there are other suppliers.

Do you have a bad gasket? I just bought some Yammi ones as spares. I don't think I have a leak problem but I didn't want to be stuck with-out them.

Try Oregon Trail Sports SKU: 8FA-14623-00-00 are $10.12 each for stock.

Copper ones would be the way to go but they are super expensive compared to stock. I am sure they would last 10 times longer though!

 

[Zipperno]

Were all out of these. Not sure when they will be available again.
They are handmade in a lathe so it takes alot of time to make. The problem is to find the correct copper stock to make them from.

Our price is 35 USD a piece.

Some guy over at TY is also making them. I belive he is in Canada.

Just trying to help.

We can make them if anyone wants them. Going to make a batch as they keep blowing out.. Not sure on cost yet. Just gotta see what I can get different materials for..

 

[Thistledoo]

We made a very small batch to try and the hardest part is finding material. Its VERY VERY expensive even if you can find it. And its pretty labour intensive to make them too....

 

[BBNytro]

I would be interested in 2 or 3 sets if someone is gonna try making a batch.

 

[Thistledoo]

Got a few sets ready to go here guys, pm for details.

Money sent! Thanks Brendon.

 

[SLY]

There is a new improved Yamaha part for this

 

[thamax]

do u know the part # by chance

 

[Thistledoo]

Ya and they still don't hold up. These (copper) don't go anywhere and don't break down with heat cycles and time

 

[Thistledoo]

These will fit nytro or apex, not sure about a phazer as I have never had one apart. Can anyone chime in on that??
Heres what they look like....pm me for details

 

[Tuesday]

Package arrived today, they look great. Probably wont be putting it back together until sunday. Did a test fit over the bellows they look perfect.

Thanks again,
Tues

 

[Thistledoo]

No problem....I'm well over have sold out of the first batch of donuts....so If anyone wants some even for summer time maint I'd grab them now as I'm not sure if or when I will do another batch. Copper is going up daily and hard to find and very $$$$$$$ thanks Brendon

pm for details

Thisteldoo

what copper did you use in machining these?

alloy 101 or 110?


what is the inner and outer diameters of the donut as well as thickness/depth?


I have a 1200 on boost and my donut dimensions are:

inner dia = 2"
outer dia = 2.5"
depth = .75"


would one of your donuts work for a skidoo?

 

[Thistledoo]

yamaha donuts are a way smaller than that....sorry not gonna work.

Fab one up.

 

[Tuesday]

Donuts in, bellow fixed, header welded..........back to pulling boost again. Donuts fit perfectly, hope I never have to change them again.

 

[Thistledoo]

Almost out...anyone need some even for next season? Not sure when I will have more.

Thanks guys

Got two sets of 3 left any takers ? And the phaser is the same size donut
