[QUOTE="greg brillus, post: 140174, member: 597"] Oil leaks.........The main one were the gearbox main shaft passes through can be sorted, but i think they leak from the starter..........I was unable to strip this one enough to sort it out, as some of the screws were loctited in and even with heat they would not budge.......these are allan head countersunk cap screws.........main issue with them is the allan key sizes are so small, they strip out if over torqued. The ESA assembly on this one failed as well, the small donut shape bushes seemed to deform, so the pins had moved fully to one side.........hard to explain........This engine does have a TP 600 kit on it and does go rather well. We locked up the ESA as it has a Conways clutch installed and these do have a shock absorber built in...........The Conways clutches are not without issues either........this one had a massive amount of run out on the sprocket, so much so we machined up a new one to fix it.........adjusting up the primary chain was hopeless. The outer primary cover shield area that wraps around the clutch goes awfully close to the new starter mechanism at the very top, visual with the inspection cap off..........just dremel a small radius on that corner, removing say 5 or 6 mm off it to give a bit of safe clearance. I'll let you know how I sorted out the leak from the gear box shaft hole in the inner cover area.........To be continued. [/QUOTE]
