Lucky I had a couple spares I had purchased from Duane at Thatsdax that ran very true. Thanks Duane!
John, Are we having fun yet?
I did the same thing, meaning I bought kits from many different suppliers to see what I was going to be up against as far as making replacement parts. Dimensionally they are all over the Granite and back again.
Dax, Spookytooth, King up in Canada, and bike-to-moped in Kalamazoo MI, offer the best kits, the best service, and as an added bonus they speak English! Any of these guys can get bad parts from time-to-time, but at least the above mentioned will quickly take care of any manufacturing flaws.
The rest are scrap peddlers.
