Jimyacky Posted May 6, 2020 Report Share Posted May 6, 2020 Happy lock down people. I’m after a bit of advice. Seen as though we’re not allowed out I thought I’d take my fly wheel weight off. I’ve never seen one like it. (See pic ) just wonder long how to remove it without breaking anything! Do I just take it off by the large but counterclockwise? I was expecting two Allen bolts to be undone. Any help would be much appreciated. Thank you ? Quote Link to comment Share on other sites More sharing options...
huski Posted May 6, 2020 Report Share Posted May 6, 2020 Can only be that big hex nut holding it on,and probably tight fit on the original flywheel 1 Quote Link to comment Share on other sites More sharing options...

Thanks for your reply. I assume it will be counterclockwise to loosen, do you know? Ta. Quote Link to comment Share on other sites More sharing options...

huski Posted May 7, 2020 Report Share Posted May 7, 2020 The weight must be screwing into the flywheel extractor thread which is conventional R/H thread 1 Quote Link to comment Share on other sites More sharing options...

The instructions above look led like a reverse thread and it’s hellish tight. Don’t want to strip anything. Ta Quote Link to comment Share on other sites More sharing options...
huski Posted May 7, 2020 Report Share Posted May 7, 2020 I'm thinking I might be wrong on that,been some time since I removed one.Id call Gas Gas UK to be sure.Logically it would be LH thread where the extractor goes in so that it tightens into the flywheel as you tighten the extractor bolt 1 Quote Link to comment Share on other sites More sharing options...
huski Posted May 7, 2020 Report Share Posted May 7, 2020 Just had another look.The instructions clearly say the nut is R/H thread,so anti-clockwise loosens it.But the weight is still screwed into the flywheel which you would remove clockwise.Youd have to stop the crank turning and have a tool to locate in the holes in the weight to turn it,good luck 1 Quote Link to comment Share on other sites More sharing options...
cascao Posted May 7, 2020 Report Share Posted May 7, 2020 Not tightening this nut with proper torque is one of the reasons why sometimes wodruff key shear. 1 Quote Link to comment Share on other sites More sharing options...
Jimyacky Posted May 7, 2020 Author Report Share Posted May 7, 2020 Sorted. Thanks everyone. 32mm spanner turned anti-clockwise with rope threaded into head via spark plug hole. (Usual oil filter grip wouldn’t hold it) to prevent movement of flywheel. Steady release. It’s like a new bike, much more responsive, I’ve been riding a donkey. Much appreciated.
