Dealers don't want to help with rejetting on carburetor bikes. I'm not surprised.

My spouse has a 152.5 with her Trapp and 14 disks.

I was trying a 157.5 with my Raask, but I just changed it back to a 155 because of the soot in the pipe and on the brake actuator arm....not sure what I'll need when I get the head back on though

likely just as well - they'd screw it up anyway - now a independent shop that works on a large range of bikes is a different story - actually found 2 still in business in my area(s) - mostly wrench used ones for resale - but are willing to work on anything looks to me like

Hello everyone, I wanted give an update on the my bike. I rejeted the bike this weekend with a 152.5 and shaved the white space in half. This made big difference in the performance of the bike. The bike no longer has that laggg when excelerating. There is smooth power from bottom to top. I had to adjust my Idle and Idle screw because it kept dieing. Now it idles and runs so much better. It does continue to back fire. I guess I will never get rid of that. Does anyone have a suggestion on fixing that back fire. It is not bad but it does backfire.

remember to torque the bolts keeping the header on the engine when engine is cold - also only torque to recommended setting. Greg also has advised (said it was an old rule) to check them again later after you have ridden the bike for a while.

I know I did mine - thought I had a leak @ muffler end & thought to check these bolts @ same time - one was no longer @ correct torque setting. had no leak anywhere (no popping or banging after tuned carb), but this was before I tuned carb & was trying to minimize my back firing somehow. Almost gone now - just once in a while which is OK by me.

Seems like you really would have had an exhaust leak without one.

Sure it just wasn't all black and nasty up in there? Mine looked like part of the head when I removed it. Really.

Don't wanna put a new one on top of the old one....

I say that because of the expansion of the different metals with the bolts and the head, plus the gasket is a crush gasket. You don't want it too tight, just enough to stay together and seal good.
