jmclane - really good job so far for someone new to the forum.
Not sure how many Bikes you have built before, but good wok on the exhaust headpipes
Did you airbrush the exhaust pipes? heat staining?
too bad you are using the Tamiya supplied "black" tubing for the brakes and clutch lines - they are too large for the correct scale - try using more scale appropriate tubing from T2M or Top Studio etc.
Otherwise looks good.
How much trouble did you have with the HD chain?? I tried building one but it keeps falling apart.
Cheers
John
