The rebirth of Lazarus

I did wonder about the adjuster, will check it out, cheers Bryan

They can crack and bind, the outer that is

Still having issues with the clutch, slips badly if i feed the gas in too quick. stripped the clutch down and does not seem bad as in the plates not too thin. However the springs are longer than the manual states, but would that make it slip? I would have thought it would be the opposite. I do have another clutch I can try, and that has the shorter springs. At least I had a ride out and got home without an unplanned stop.

My original 500 used to slip like buggery on take off if useing a handfull of throttle taking several hundred yards(old english measurment) before stopping, never wore out and gave up worrying about it

Doesn’t help when trying to wheelie!😂

Never managed a wheelie on the 500, but i was 21 stone at the time!

More than happy with both wheels firmly on the ground these days!😁

Still having issues. I put another clutch in and it is better but still seems to slip at higher revs. It's adjusted correctly and works smoothly. I did replace the springs with the correct length as the originals were extra long. Would using longer springs make it less likely to slip? Cable is new and correctly routed. Also not running right, when pulling away from a standstill it has a bad flat spot and will almost stall unless I give it loads of revs. Had a quick look at the plugs and very sooty. Carbs have been cleaned and synchronised.  Engine sounds a little flat when accelerating, not sure what to do next.

Points gap and timing first

I managed to get rid of that pull away bogging on mine by leaning off the air screws.

[mickwinf]

Will re check timing but was spot on, will keep looking.

From the plug colour it does seem like its possibly rich enough to knock the edge off response and crispy-ness.

Worthwhile turning the idle adjust screws out half turn ...... to judge if there's significant change or not .... as experiment and investigate evaluation.

Quick and easy to assess effect, free too 

[mickwinf]

so I have gone back to basics, timing is perfect with new Honda points, and reset the valve clearances. There is an occasional spit through the exhaust so I have taken the carbs off to clean again and check float heights. only done one carb up to now, but float was wrong and also the needle was set in the second to bottom groove, am I correct it should be second from the top? that would explain the richness. Carbs are 627b mains 100 slow 40s.

I seem to remember middle notch for needle which is 3rd from either end

[McCabe-Thiele (Ted)]

Both my 400 & 500 needle clip is in the middle position 3 counting from either end.
