Aprilia RS 125/ KTM 640 LC4 Supermono

Started some of the work on the winter rebuild and wanted to test another Tacho, however now thw starter spins but doesn't engage. Suspect the Sprag clutch. Ordered flywheel puller. Got it apart and garter spring knackered so replaced it and re-assembled still the same. Took t out again and on closer inspection, the cage that holds it all together is broken due to rear on one side. The tabs on the circlip are supposed to be retained on the outer ring   but these bits have worn off so circlip is not retained. Ordered new Sprag (freewheel clutch) £70 from Fowlers. Not taking chance on Chinese Ebay jobbie.

The latest trip to Mallory on 5th November was a complete success. It went well all day and completed all 6 sessions. Had a couple of things to adjust during the day but nothing that was a problem. The front end was very good, could really push it into corners, (we had cold and wet and cold and dry). Only small slip was rear coming out of the hairpin. The back end shock was disappointing. It needs a decent shock with correct spring rate and both ways damping. I might add a ring to this one to give a bit more preload but something better is needed long term. The corner speed was really impressive, had the confidence to push round the outside of loads of riders round Gerrards. Little bit conservative as temp never got over 9 deg. Its fairly gentle on tyres and fuel.  Could be a a keeper for me, its light and nimble and changes direction so easily, I found I could be very precise in corner entry and hit an apex very cleanly. Few things to do in the winter;- May need a sprag clutch at
