Thanks guys!

I'm still having a bit of wobble in the outside rim of the front comstar. I've had it up to 85mph and there is still no shake or anything through the bars, so I'm hoping the wheel is just a bit out of round (and balanced properly). Brake rotors are still dead straight so there is no movement at the hub. Is this normal for comstars?

Bike looks great how was the fitment of the exhaust pipe

Thank you! the exhaust can be a bit of a pain to get all 4 headers lined up with the head. Just takes a bit of muscle. Once it's in it fits the bike really well.


Here's a recent shot of the bike:



Do you get any speed wobble at higher highway speeds?

nope I've been up to about 85mph and it feels really solid

only annoying thing is a vibration through the footpegs that makes my feet go numb after a while. But that feels more like it's from the engine as I don't really get it through the bars.

If you haven't experienced numbness in your hands riding with clubmans, you haven't been on a long enough ride!  ;)
