ham2 Posted December 7, 2012 Report Share Posted December 7, 2012 Have a rummage around this and its associated videos, its all in there somewhere but I can't be ar5ed to look. Most Pro owners just do it from memory or have you had the bike less than 6 months http://www.youtube.com/watch?v=hjoj7n74G0s Quote Link to comment Share on other sites More sharing options...
itsafive Posted December 8, 2012 Report Share Posted December 8, 2012 There is a 'blind' bearing, of a needle roller type, that supports the back of the shaft. If you look from the gear change side of the bike you'll see a silver circle above where the cases join. This is the back of the bearing. Remove the clutch case (drain oil first) and remove kickstart assembly. Knock the bearing out from behind. Quote Link to comment Share on other sites More sharing options...

lineaway Posted December 8, 2012 Report Share Posted December 8, 2012 (edited) It`s a five nice reply. I was thinking it was just a bushing. http://www.youtube.com/watch?v=pQ7OmoyATgU Assembly for the kickstater starts about a minute 30. Good luck.

cwill83247 Posted December 8, 2012 Author Report Share Posted December 8, 2012 Cheers guys all done well of another issue now When I kick the bike it starts but it sounds like its rubbing on the idler gear and can't work it out ... I push the kickstart shaft in and all is fine just not returning naturally Quote Link to comment Share on other sites More sharing options...
lineaway Posted December 9, 2012 Report Share Posted December 9, 2012 (edited) The problem usually is the shaft is not all the way in the bearing. The washer sometimes holds the whole mess up. What else did you replace as I had never seen the bearing being replaced before. Did you watch the dideo on assembly? http://www.trialscentral.com/forums/topic/43294-kickstart-problems/ Edited December 9, 2012 by lineaway Quote Link to comment Share on other sites More sharing options...
hrc1 Posted December 11, 2012 Report Share Posted December 11, 2012 Usually kickstart return spring gets twisted & needs replacement Quote Link to comment Share on other sites More sharing options...
cwill83247 Posted December 16, 2012 Author Report Share Posted December 16, 2012 Thanks all now fixed !!!!!! Happy days !!! I watched the video from Jim on youtube same one as lineaway posted in his response shows removing kickstart and more importanty replacing the kicstart and pre-winding.. if you search youtube for Gas Gas Pro or search for gasgasinfo loads of really good videos.. you have to watch them and pick out the bits you need.. the actual bearing i used a copper bar and tapped out from behind exactly as itsafives resonse above... My issue after I fitted it all with rubbing on the idler gear seems to have been that I had not fitted a washer that sits on the kickstart shaft between the casing.. Thanks again !!!! Now just have to learn to ride Quote Link to comment Share on other sites More sharing options...
