Blueing in exhaust

[star4772]

I noticed today that my rear cyclinder on the right side on the exhause pipe looks a little black and blue. Does anyone know what might cause this,to rich carbs out of sync? Maybe we can take care of it at maintance day at Freebirds? Also I would like to install frt and rear brake pads yes???

 

Thanks Joe

Rear Cylinder ? Are you talking about the painted fins or the chrome cylinder head cover ?

 

Black around an exhaust would indicate a leak to me.

Installing the brake pads at Maintenance Day shouldn't be a problem.

No this is where the 2 exhaust pipes come together just before the muffler, you know how the harleys exhaust turn blue color. This is what I mean maybe running to rich.

Leaking joint at the Y pipe is a known problem on many of these bikes - if your bike is still under warranty, they will replace it. If not, we can fix it with a little JB Weld. We did that for Don's bike in Fort Collins last year. The stuff you see on the chrome heat shield is not actually bluing from heat - the heat shields can never get that hot. You are seeing exhaust gas deposits from the leak, and they generally just wipe off.

I see, I will try and wipe off and then I will check on the warrenty. I dont know what the in service date is.

Hey Joe, BEFORE you wipe it off, I'd suggest you just take it ASAP to a dealer and ask them to fix it under warranty - their computer will tell them if it is still in the 5 year period, but even if it is past, Yamaha has fixed stuff after warranty before. Especially something like this that is a known problem and so easy to see that the crimp is bad and had to be from the very beginning. Can't hurt to try.
