Heat blanket upgrade.

Maybe put a rag over exhaust outlet and listen? It always worked on the donuts. Should almost stall sled also.

Is it really quiet? Just really worry about fire. I have come close myself in past and saw one go down way back. Really felt sorry for the owner and remember the look on his face watching it burn.

I think it's quieter than stock! I can hear every moving part in the motor, which is a problem when you actually know what is moving! LoL
I hear the sled behind me. It's actually nice on a long ride. Dave said the quite muffler robs a couple hp but I like the sound of it.

Just peak in behind the secondary. If you take it off you can see right in. And get on a few bolts.

I'll check before I ride this morning!

 

[Joe ltx-le]

I bet your fine.

Here's what happend. I used new gaskets from ulmer. They are not multi layer metal gaskets likes the stock ones. They require a retorque after being compressed and heated. I did torque them to spec

Thanks for clearing that up.
Wonder why ulmer is using that gasket???
that just seems like a complete pain in the #*$&@, and a potential for future problems.

Robs a few hp compared to stock mufflers? Or aftermarket mufflers?

im not going to crap on allen for using his gasket. when i spoke with him he said YA of course you retourque after a heat cycle. and hes right as an engine mechanic i always retorque anything i can thats exhaust.

but the multi layer metal gaskets are the way to go imo

I wasn't asking you to crap on him. LOL
Its a legitimate question
I am honestly wondering why he has chosen to go with a different gasket from stock.
I have honestly never heard or read of anyone having an issie the the engine to header gasket on any current yamaha sleds.
While i understand your retorque statements on exhaust, I have changed out a few myself using stock yamaha gaskets and never needed to go back in to retorque them. I guess im just one of the lucky ones??

No. like I said. The stock metal gaskets are the best for exhaust. I'm not sure if there's any benefit in the gaskets that came with the header.

Yup it was fine! Did 210km and all good , I'll still retorted after Christmas.

I am also wondering and forgot to ask last time I called him. I have reused the stock header gasket at engine at least 4 times with no issue. Never had to retorque. Just wondering if I am missing something?
