speedy sie Posted June 11, 2010 Report Share Posted June 11, 2010 lock the back wheel up and have a bloody log piece of metal tube put this on the extension bar and nuckel and it could come undone,they are a twat to undo,try hitting the bolt first to shock the thred.

Jazoli Posted June 11, 2010 Report Share Posted June 11, 2010 You can buy a 12V impact wrench from ebay or halfords and use that, they only cost £15-£20 and come in very handy Link to comment Share on other sites More sharing options...
j1000rsv Posted June 11, 2010 Report Share Posted June 11, 2010 im not taking the piss but are you undoing it the right way am i right in thinking they have a left hand thread . ? good fitting socket and hammer. shock it off. Link to comment Share on other sites More sharing options...
gurninman Posted June 11, 2010 Report Share Posted June 11, 2010 They're a standard rh thread. Get a good fitting socket, use a 2 foor beaker bar... get a mate to sit on the bike, in gear with back brake on and a gert lump of wood through the rear wheel. Should come off...

allen224 Posted June 11, 2010 Report Share Posted June 11, 2010 Hi, have you taken it off before ? If not it could have thread lock on it, which if you heat it up will a blow/gas torch it should do the trick. I had same prob tried bloody everything took ages, then heated it up and it came straight off. Ya never know its worth a try allen Link to comment Share on other sites More sharing options...

martzxr Posted June 12, 2010 Report Share Posted June 12, 2010 I had the same problem on mine, ended up with a bar through the back wheel and plenty of leverage! It helps if you remove the footrest hanger bracket Link to comment Share on other sites More sharing options...
uglymark Posted June 12, 2010 Author Report Share Posted June 12, 2010 hi guys and thanks for your help , i tried every thing you mentioned but still couldn't get it to budge, so i took it to a local guy who,s a motorcycle mechanic and works from home he heated it up and got the mother of all air guns out , it was more like a bloody machine gun and after two attemps it came of . so i can now get the bike in for its mot on monday , thanks again guys Link to comment Share on other sites More sharing options...
