Gas gas 2012 txt clutch etc.

Hi 

Had a look at my clutch tonight as it is terribly rattly which I know these bikes are known for it.  I found these 2 chips on the idler gear would they have any effect on the noise?  I guess the bart gear looks a bit tasty too, although it kicks up on 2nd kick from cold and 1st kick when warm. The clutch basket and plates all look sound. I was worried the clutch basket would be worn out but it looks good. The only other thing I have noticed is the bush/bearing on the shaft going to the gearbox has some play in it. I've tried to attach a video but it won't upload for some reason. It all seems to work ok but I get quite a bit of vibration through the bars too. Any thoughts appreciated. Thanks

@Steveyboy In short yes it will make lots of noise and it is normal for this to happen regularly if used a lot on a Pro model , a pair of gears for the Kick mechanism are around £200.00 these days and the best way to make sure you don't have to buy a new pair every 5 minutes is to slowly engage the gears before you kick the bike over and also when you fit the kick start do not position it on the splines too far forwards there are two positions that were used by factory riders through the years  those were 12 o'clock and about 7 mins past 12. look at old WTC videos on YouTube to see these.

@ Steveyboy The only way to get rid of the noises is to have all those parts renewed IE the kick gear the idler gear the clutch basket and the bush and the primary drive , very expensive . It makes more sense to replace the cluch basket bush/bearings  and use a grinder on any chipped damaged gears to smooth off their surfaces where they mesh.

@Steveyboy vibrations through the bars can happen if the bolts holding the front of the bash plate to the frame are not totally tightened up also make sure all the motor bolts that hold it in the frame are tight , they do not need to be stupid tight or the motor lugs may snap.

Thanks for the replies. I might just leave as is. I'll check the bolts on the mounts etc to see if that helps with vibration. It's hard to justify spending lots of money  on a 2012  bike. It's not like I'm out every weekend on an expert route. It's a white route once a month dotted with practice at home in the week.  I do like the bike tho. Very reliable starter etc. we'll see. Time is a factor too as I guess it's a reasonable strip down to replace that bush behind the clutch basket

I think that is very wise the clutch bearings are probably fine anyway. As you say its an old bike and it isn't really worth the expenditure ,  it will all work fine even with the kick gears in worse condition than yours are now so you do not need to worry as when you ride the bike the noise is a lot less noticeable. As regards changing the bearings its a doddle there is just 1 x bolt in the centre of the clutch shine a torch there and you will see the allen head deep in the recess this bolt is drilled and has a hole through it for breathing of the gearbox casing so it is weak you must make sure that the allen key that you use fits tightly or it will round off and you will have to drill the head off so care is needed , with luck it may be loose.
