MC21 flywheel, bored standard carbs, Tyga exhausts, etc.
It was running out of steam far too early, even for the useless MC28 that it is. Removing the airbox helped it to breath a little more. I might put the airobx back on though as it makes a little more power around 4,700
Clutch started to slip a bit, so we found some old valve springs off an XR500 or similar - was all that we had at hand.
The dip around 10,500 would be nice to smooth out as would the lack of over rev after 11,500. it should really keep on a bit more after that I would have thought. Perhaps some 300 specific pipes (Matt, Matt??) would perhaps help here. I have the PJ38 set awaiting in the wings for a later date..
