Hello,

I have a new stainless header pipe and new exhaust pipe for my R27 and have a question on the fit on the motorcycle.

When I put it on the head and have the muffler on, the mount for the muffler is about 1" away from the silent block bushing (see picture). I can push it in but I do not like the way it puts pressure on the exhaust spigot. I am not sure if it matters having a bit of pressure on the exhaust spigot.

Also, the front mount on the side of the engine is about 1/2" away hole to hole a well.

The vertical spacing (up/down) looks good, its just the left/right spacing is away from the bike.

Any help or advice is greatly appreciated!!!

James

R 27 exhaust

Hello James
IIRC, the muffler bracket mounts on the INSIDE of the silent block......counter-intuitive, though correct.
That forward ring clamp mounts to the engine bracket just about directly below the forward pushrod.
I too had a bit of difficulty in fitting my new pipe. Needed everything assembled loosely and wiggled a bit before is all fell into place.
I did not have to bend or strain anything to fit, just worked and wiggled until it went easily.
Good luck.
Cheers,
Hugh

Interesting

OK, WOW. THANK YOU!!!

When I first went to look to see which side it went on a couple days ago I googled it and saw it on the outside so that is where I put it. After reading this I looked again and about 50% are on the outside and 50% on the inside! WOW! Some on the outside even have a large spacer between the pipe and the block which would fill the gap. Interesting.

Well, its going to be 2 weeks for me to go back to the bike and try it on the inside so I will update when I try it. I guess buy changing the angle of the pipe you need to rotate the head pipe which will change the angle. Interesting!!!

And again, Thank You to Hugh and the community!!!

James

Some of the repro/aftermarket

Some of the repro/aftermarket exhaust parts fit poorly. Many years ago I purchased an Overlander stainless steel exhaust system for my R27 and the fit was so bad the header interfered with the frame! I shipped it all the way back to Australia from the U.S. but was never refunded my purchase price.
