Details?

Ahh good, not just me then :-)

Happened to me recently too, only after buying and fitting a new clutch did I find out that my slave had been slowly leaking oil into the engine. Couple of slave cylinder seals and a power bleeder from Halfords did the job. Clutch is perfect now and does not drag at all ;-)

Yeah that must be it. Bike rode fine all day yesterday and the kick starter is much nicer now its moved round one spline :-)

Yeah thanks, had to replace the idle gear but the pawl gear was fine luckily :-)

Thanks, yeah I've had a good look at it and it seems just fine. Must have been lucky :-)

Thats odd, it was a 2011 cover that I bought today, was sealed in a GasGas bag and came with no seals etc :-( Fixed the bike all up today already :-)

I know! Wouldn't it be cool if parts came with all seals and fittings already fitted. An £80 cover suddenly costs over £100 when you add seals and all.

OK i've maybe answered one of my concerns above: 2: Have moved the kickstarter clockwise by one spline tooth, this seems to get the pawl gear engaged quicker therefore giving me more travel to start the engine. Out riding tomorrow so will test out the theory over the day.

Idle gear was shafted, pawl gear, kickstarter shaft and the bearing the shaft seats into looked fine, so after a trip to my loacal (and really well stocked) trials shop BVM this morning and an expensive shopping list the bikes back together (wish I hadn't of taken the engine out yesterday though!). Parts needed: 2011 Clutch Cover Clutch Cover Gasket Kick Start Oil Seal Water Pump O-Ring Water Pump Seal (Didn't actually need that) Kick Start Idle Gear 2x Clutch O-Rings Sight Glass Total £185 Idle gear damage... I do have two concerns though: 1. There was no trace of any pieces of idle gear anywhere in the clutch cover or clutch basket side of the engine. The teeth do look very rounded and worn though rather than sheared and snapped so I figure i'm unlikely to have found any chunks anyway. 2. The kickstarter still dosen't feel right to me, didn't feel right when I first got the bike a few months ago and i've probably been kicking it wrong to compensate which is probably why the gear went and cracked the case. The kickstarter dosen't feel like its engaging the engine until the kickstart lever is at about the 9 o'clock position, and this dosen't leave enough travel to actually start the engine. This means ive been having to almost start kicking the lever BEFORE my foot is on it! Which I know is a big no no as it can stress the case and idle gear. Obviously If I stall it mid section I can't stop and start rocking the bike about etc, I need to be able to just kick it again and carry on so really want to get to the bottom of this?

lol yeah I just had to fit a new clutch cover and they don't come with a sight glass, figured it out in the end. Just pushes out (away from the engine)

Anyone know how to remove this?

Just about to go pull the clutch basket so will post back what I find, wish me luck.

Ok thanks. Will have a look in the morning then and see where I'm at. Will post back on here what I find. Is there anything or any specific way to do any of it that might not seem obvious.

No not really. Its not the usual clutch rattle.

I think it might be the pawl gear as I have had the kick starter jam up a few times, I take it thats clutch basket out and I should be able to see from there?

http://www.thumpertalk.com/topic/693585-gas-gas-pro-kick-starter-gear-problem/ This what you mean? How do I go about checking that out?

Not sure what you mean? Since posting this ive got the engine out so whats the quickest and easiest way of finding out what the rattling noise was? Is there an easy way of checking things like the piston and crank etc? Also if the starter shaft play is OK how come the case cracked? Hoping to have it fixed by tomorrow night so help really appreciated! If I'd lost a bit of oil due to the cracked cover, what damage would that have done to the engine, anything that would be likely to cause a rattle? I'm leaning towards the starter shaft idler gear (is it?) from reading online, apparently it can cause a noise that sounds like an engine rattle, how do I inspect this and change it?

Try now

http://youtu.be/9O93JWXvBB0 Took the bike out today and it started making rattly noises, sounds to me like the piston but when I started looking ive noticed the clutch cover is cracked around the starter shaft. So two questions: 1. Should the shaft move like this, if not what do I need to fix it? 2. Could that have been the noise I heard that I thought was the piston?

I was a Beta fan til I got my Gasser, to me it rides better, works better and is easier (and cheaper) to work on. Thas just my opinion though and thats only based on owning an '04 Rev3, an '04 GasGas and riding with and tinkering with an '09 Beta Evo and an '01 Sherco. For me in a nutshell, the Beta felt well made but the GasGas felt lighter and more capable.

You could use Heli Tape, that's what MTB'ers use, not sure how much protection it'll give on a trials bike though?

Yeah but they out handle any other bike on the tarmac so thats where most people ride them :-)

Great editing/filming on that Supermoto vid, that's REALLY made me want to take mine out but its raining :-( Mine for anyone else interested in Supermoto:

I wouldn't spray wd40 near bearings as its a degreaser.
