    Rear swinger

    Tighten until it doesnt stick and no play is present. Could be bushes are worn irregularly. Easy to make a new set with small lathe and a 14mm drill or Martin Matthews at motoswm could prob sell u some decent ones at a reasonable price... Stu

    Flywheel Weight

    Some pics of my flywheel findings - with further mods this weekend Carb, timing and ignition "settings" bike now revs out much better and am liking the lighter weight much more than last time I rode with it. Was too stally and weak feeling. Am still going to make one with in between weight (I like the sound of Burgat recommendation of 800g? removed in a previous post I read) Grip is affected but nothing that throttle control and body engish shouldnt sort. Best wishes Stu

    Flywheel Weight

    Hi Must admit I would only mod my main riding SWM for reliabilty / maintenance reasons - really like to keep em as original as poss - and wouldnt dream of changing me "Bernie Jumbos" from their "standard works guise"!! Not that I wouldn't ride em in anger - far from it - just that they both STILL have broken kickstart shafts that MUST be fixed before next years Bill Pyes 3 day as I promised me mate Scrumpy that we both ride one each at this event.. Need to sort some motivation, space and

    Flywheel Weight

    Hi The 320s are 276cc Flywheel I bought seemed to be a home engineering job tho hard to tell with passing of time. Is it the Dave Renham Bultaco kit slightly modified?? I thought about this but wasnt sure how to trigger signal from a std flywheel?? Would LOVE to lose my points Cheers Stu

    Flywheel Weight

    Hi Good thread Not posted on here for yonks - but couldnt resist this one. I have lots of SWM bits but couldnt find any spare flywheels so I bought one from ebay with the idea of lightening it. Then my mate returned one of my spare flywheels that I had inadvertantly given him in a box of Gori bits. As soon as he handed it back to me I realised that it seemed VERY heavy! the last flywheel I had held was the ebay one.... Putting the 2 together I instantly realised that the one I had bought to lighten had already been done!!!! VERY strange indeed. It has had a couple of mil taken from both its diameter AND its face so is a fair bit lighter than STD. I rode the superb Cumberland County 2 day classic at the weekend and after a dothery Saturday decided to test me new flywheel on the Sunday WOW what an amazing difference - felt like riding a Fantic!!! LOL will endeavour to weigh it and compare to original next time I am in the garage. To be honest it was a little too whippy and seemed to rev out far too quickly - reckon a bit of re jetting and or exhaust work and it will feel more like a "340" Fantic (which isnt always a good thing) Best wishes Stu
  15. many thanks for your informative replies and pics - the start of an interesting journey i think... stu
