2Smoke Posted November 6, 2013 Report Share Posted November 6, 2013 Have just pulled the gearbox out of a friends 5VY R1, there is a fair bit of damage to 5th & 6th also 3rd(?) has been eaten by the selector fork! It's a track bike, guessing its been a racer in the past. Has a quickshifter through a pc3. Before I start rebuilding with good parts, is there anything obvious I should be checking that could have caused this? Link to comment Share on other sites More sharing options...
2Smoke Posted November 6, 2013 Author Report Share Posted November 6, 2013 Will do mate. He's actually brought another gearbox along with the bike, so have the parts. But I do need gaskets.. will have a look at your PM now! Link to comment Share on other sites More sharing options...
Alex_H Posted November 6, 2013 Report Share Posted November 6, 2013 A friend of mine did similar damage to his 14b box recently, was the qs apparently, not setup properly, though this was through a kit ecu/loom Link to comment Share on other sites More sharing options...
Rich Posted November 7, 2013 Report Share Posted November 7, 2013 I would think that overheating damage like that was caused by constant pressure on the gearlever, probably from an incorrectly set up quick shifter (as mentioned above) Link to comment Share on other sites More sharing options...
2Smoke Posted November 7, 2013 Author Report Share Posted November 7, 2013 Thanks all, as I suspected. Just need to read up on setting the quickshifters properly now! Link to comment Share on other sites More sharing options...
sonic Posted November 7, 2013 Report Share Posted November 7, 2013 A few years ago Quaife had gearboxes for the early R1's on offer.I think mine was half price at £650 ish.Might be worth it while it's apart if they have any left. Link to comment Share on other sites More sharing options...
2Smoke Posted November 7, 2013 Author Report Share Posted November 7, 2013 Don't think he'll want to spend that much on it. The bike gets used rarely as it is! Thanks anyway though Link to comment Share on other sites More sharing options...
