I purchased a Pro Circuit T-4 exhaust, Used and it came with a couple of end caps. So I bolted it on and started the bike to give it a listen, warmed it up, shut it down to change the cap to compare. Upon restarting, it kicked back when I was near the bottom of the kick. The lever stayed down, so I pulled it back up. It seemed a bit stiff, but as not to be a quitter (even with a sore foot), I kicked it again and it started. There was a heavy grinding, so I shut it down right away and walked out of the garage. After Christmas at my house, it got the best of me so I went out and tore it down. I found that the finger on the ratchet wheel had broken the stop plate, and then slid down between the case and the guide shearing off the top bolt. The bolt was easily removed, and I ordered the stop plate, guide plate,lock plate for the bolts and 2 new bolts, and all the gaskets and o-rings to do the job for around $30. Not to bad, but the finger also banged up the case down to just past the top bolt hole. I figured I'd get the parts and lay them in there to see how much repair th case is going to need. I'm thinking if this was a professional repair it would get a case, but money is tight. I'm wondering if this has happened to anyone? How was it fixed? and How did the repair work? I'm thinking if the area behind the stop plate is minimal, JB weld might do it, but if it's huge, I may need to tear the whole thing down and have it welded, or take a bit more of material out and make a spacer. Any input would be cool. Thanks.
