So since me and my buddy started up our little after hours repair shop we've done several chain and sprockets jobs. So at my suggestion a couple purchased the vortex "go fast" kit which is basically a kit with a -1 front sprocket which is nice on the 600's and 750's I've put them on. Well I noticed that once on they have that "tight spot" issue when trying to adjust the chain and I'll have it set perfect at one spot and then roll the wheel and it'll be too loose or tight. Now I know a lot of people have said it's normal until the chain wears in but I've had 2 come back for adjustments after putting over 1k miles on them and they still have the same issue. I double checked that the master link was not over pressed and tight and made sure I couldn't find any tight spots in the chains at all. Now I ride with these guys so I know they haven't excessively beat on the chains so it's got me scratching my head a little. Then last night while doing some work on my busa (gps sensor FINALLY, oil change, new road attack 2's) I went to adjust my chain and I already knew it was over due to be replaced but I realized that I've had the same issue with my bike ever since I installed the vortex sprockets and the zvx3 chain but now it's really bad because everything is so worn. I've just always dealt with it because it wasn't horribly off but enough that I noticed so it's got me asking myself if maybe the vortex sprockets aren't made perfectly round and why I keep having the issue and wondering if anyone else has experienced this with vortex or any other sprockets.
