Putting my new jug huggers on tomorrow. Does anyone have the torque specs for the pipes at the head and at the brackets? What color loc-tite should i use and shoud it be used at the jugs? recommend any ultra copper or siliconeat the jug? Thanks, and please feel free to add any advice-the instructions from bubs are a F'n joke! No torque specs etc. just the obvious is mentioned. I even called and complained to bubs about their instructions and they agreed with me that they suck!!


I will hopefully be able to tell you how they sound by late afternoon!!

There's one little tidbit of info no one ever mentions. When you mount the pipes, mounth them loosely. Then snug a little at each bolt moving around until all is tight. If you end up snugging one up then another you create stress points in the pipes.

The service manual calls for 14ft.lb of torque for the front exhaust nut and 17 ft.lb for rear exhaust bolts. The install for the Yamaha S* calls for 11 ft,.lb at the cylinder heads and 15~18 ft.lb at the muffler /collector joint clamp. My personal recommendation is to get brand new oem gaskets and install with the lowest recommended torqe setting (11 ft.lb). Then after install fire the bike up and check for leaks by sticking a thick towel on the outlets for a moment at check for leaks at the heads......go for a ride and then recheck the torque...I've had my S* with a 11 ft.lb setting for over 3 years and no leaks.

I installed my street sweepers using the torque specs from the service manual. 14ft lbs on the front pipe, and 17ft lbs on the rear pipe. But I did it in steps. It might seem anal, but I started with 5ft pounds on each nut/bolt, and worked my way up to the torque specs 2 foot pounds ata time. I have no leaks and I don't think the torque could be any more even doing it this way.
