[QUOTE="Phil Baker, post: 34486, member: 2693"] [SIZE=4][FONT=times new roman]If it seized at all it was only momentary because as soon as I felt it losing power I pulled in the clutch and drifted to a stop as it ticked down to full stop. After 5 minutes cooling it started again, no problem, and I rode it home. The breather problem may be because there is no oil returning to the tank now, for some reason. I fitted an undrilled oil cap and wonder if, now that it revs a lot more eagerly, there is an airlock forming and the oil just goes into the sump and out of the breather as soon as the sump is full. Do I need to somehow prime the oil pump again? Jetting : I just refitted the 29/3 (had a 29/4 in it) slide and put the needle on 3rd slot and it's ticking over far too fast (can't slow it with tickover screw and eight-stroking. Silencer - I poked a piece of pipe down each end and there's only about 150mm of baffling with the 10mm hole...... what happens if I bash it, then? :mad::o Phil [/FONT][/SIZE] [/QUOTE]
