    Well I've tried different setups with these Barnett plates and I'm back to the six heavy duty springs and all fine until all assembled with oil and it slips still,I've turned them in , and backed them off 31/2 turns then trued the clutch up,I can't have it slipping I can't even start it now,every other kick is spongy,next I'll try pulling the lever in and tighten the springs up tight,what do you think ? Can't see how you run it with 4 springs, Cheers Andy

    Cheers Larry I thought three because it would be even,I use a three spring clutch on my grasstrack bikes which run dry clutches , I've run an extra wire from the handlebar switch to the rectifier to try and stop the smaller festoon bulb from blowing,see how it goes,I'm going to leave the mikuni on as it's running good cheers again all andy

    Erratic Running

    After what I've been through with my bike I would say its a carb issue,not sure what carb you got fitted but the a also used to accelerate when you leaned them over it was a float issue cheers andy

    Cheers graham,just a probl with a few blown bulbs,as with the clutch, can you run with just 3 springs, I've fitted the heavy duty springs, and is a bit heavy on the lever cheers andy

    Yes graham I think you could be right,it has the nuts on the springs on the clutch could be either ,but if only I knew before,I've machined a washer,new drilled nut to lockwire which was missing,all nice and tight now,assembled the clutch ,alignment good,the tensioner doesn't run true so I took it off,and with the mikuni fitted started her up and hallelujah it bloody runs !! Revs and ticks over a treat,I nearly wet my pants cheers for the help, wouldn't have got there without you all,not sure if it was either the carb or missing washer but they've both sorted it,tomorrow I'll take it for a spin before I long wire it up and put the cover on. I'll let you know how it goes cheers again andy

    I've seen the light with the primary issue,it would seem that the flywheel has been changed at some time,and one from another model has been put on ,with the single outside weight,after trawling the net for pictures ,it would seem that it as said before ,should have a 4mm counterbore to tighten the sleeve up but this hasn't ,so the sleeve has been floating,I've fitted the new seals and weighting for some small bits from in motion to put it back together,mikuni is fitted,proof will be in the pudding as to say,tomorrow I should have it back together ,I'll let you know how I get on cheers Andy

    It's a motoplat electronica,I've had it checked,guess I'll have to make up a spacing washer,I've already discovered bits missing ie,primery chain tensioner so I'll check the alignment,in motion told me that the sleeve is the correct one 28.5mm but sprocket has no counterbore looks like there is an O ring both ends of the top hat cheers andy

    If you have the Haynes manual it shows the step 11.9 picture.either there's a washer missing between the top hat sleeve and cog or there is something's not right because the back side of the cog is flat and will only tighten against the shoulder of the shaft cheers andy

    Sorry about this I asked this before but I'm still unsure,the sleeve that goes into the seals ok but there is a 4mm shoulder on the drive shaft,which in the Haynes manual looks the same,but this means when running the sleeve will move in and out,should there be a 4mm washer spacer between the top hat sleeve and the back of the drive cog\flywheel weight!I've got it all apart at the moment to redo the seals!I don't see the reason for the O rings if their not clamped in place,in motion have given me a mikuni to try,I can return it if it's not the carb cheers andy

    I'm going to redo the seals,is the wear sleeve that goes into the seal supposed to be free floating ,what alternative carbs are there,I'm a bit apprehensive in spending out on a new carb without knowing it's definitely that cheers andy

    Is there anyone in the wolverhampton area with a bing 28 I could borrow ? I changed the jets not a lot of difference and took the rear silencer off to see if it made a difference but nothing so it's looking like a trip soon and start from scratch
