Easter is imminent

Posted my entry forms yesterday for the Festival of Power and the first entry lists are already out. Bit of a change this year too as we will not be running in Competition bike. It seems daft to start the season in comp bike only to have to move to funnybike partway through the season once i have the new bike done, so I've entered funnybike - it's a no brainer anyway, the entry's will be better, I'll probably do ok and the prize money is better.

For now though things have gone a bit backwards. I was almost ready to refit the engine on Wednesday, but after fitting the clutch basket and hub i discovered the wobbly clutch issue i though i'd fixed was not actually fixed - just as bad as ever i'd say. However - i think i've now got it sussed and it explains why the bearing surface on the clutch was worn oddly.  I tried fitting the whole clutch, the gear, the spacers, the hub, all the same parts onto an input shaft in another set of cases and suddenly the wobble was gone. It only shows itself when you tighten the hub nut too, but even with that tight in the other cases it was fine.
The culprit then? well i'd never have imagined it but the big bearing behind the clutch is garbage, it's not broken, damaged or worn, it's like new but one side of that bearing isn't flat, and the whole clutch bolts up against it, which explains everything.

Some parts have arrived recently, 48mm Lectron carbs to go with the V&H head and a set of titanium valves for it arrived today too. I've since made a wide open throttle switch for the lectrons as my current setup won't work with them. Basically i made a replacement carb top with plunger and microswitch. Works great.
