Title: R65 - exhaust
Post by: NorR65 on February 06, 2010, 04:27:10 AM

I have got new down pipes and Sito silencers om my R65.
I noticed that the rear wheel is not in center between the silencers.
The space between left silencers and rear wheel is 2 cm more than the other side. Is this the way it meant to be?

I don't know for sure.  Mine are the same though and they are BMW silencers so I'll be interested in the answers you get. I often wondered if the bike had been dropped on the RHS.

It's extra clearance to remove the rear wheel .

Although you did not mention the model year of your R65, if it's a twin shocker, you may want to confirm equidistant spacing at the swingarm /chassis pivot. I little off there could effect your alignment measurements and questions.   Monte

Thanks for your help.
It is 1981 with twin shocks.
The rear wheel is in center of the back fender.
I leave it, its just a small cosmetic problem.

Using the rear fender as a guide may lead to a misalignment.  The swingarm/frame spacing at the bearings should be equadistant on each side.  Start with that alignment, then for cosmetics you could adjust either the fender or muffler as required.

All manner of alignment and handling issues can arise if the swingarm is not aligned correctly.

My fender is actually a bit out of alignment with the tire/wheel, though the wheel/swingarm, etc. are well positioned & centered.   While it is an annoyance to my Virgo sensibilities, I haven't bothered to try to straighten the fender yet.

This makes sense to me. The rear wheel is not the easiest to remove and certainly needs the extra clearance.
