If you need a roadworthy, then SJ's is pretty good.
I have never had them work on a bike.
When you rock up you are greeted by a stack of bikes out the front. Most of them are pieces of shit, write off's, and other pieces of junk that I believe he wrecks in his spare time. Everything from HD's to scooters.
I didn't realize he had a dyno... Probably because the shop is very cluttered.
I'd visit his shop and have a chat and a look around. Sis is probably a good mechanic, but house keeping is not his specialty.
I have seen a couple of HD wrecks there, but can't say I've seen any in for servicing.
