    Yep, but I think I'm better off doing this now with the zeal because it's my first bike and it's probably going to be cheaper than future bikes I'll own. Plus it's the holidays from uni for me, so I don't have to use the bike for commuting, which means it can stay off the road for a while as I take my time to figure out how to do this.

    Fair enough. But Zeals are quite complex wee things. And don't let that jrandom dude mix his bits up with yours...

    I'll be careful.


    I found it difficult to drag myself away from the computer today, so didn't get much done. But I did go to repco and get myself a set of feeler gauges so I was able to measure the valve clearances. The exhaust valves are all 0.254mm except for one that is 0.229mm. The inlet valves are (starting from #1 cylinder and working across (in mm):
    0.127     0.152     0.102     0.076     0.076     <0.038     0.102     0.127

    Now I've gotta find out what the clearances are supposed to be and with a bit of luck I won't have to replace all the shims. The valve with <0.038mm I don't actually know what the clearance is because 0.038mm is the smallest feeler gauge I've got and even it didn't fit through. I even rotated the crankshaft through a revolution to make sure nothing had stuck, and got the same reading.
    While I haven't got a zeal manual, I do have an fzr400 manual, and the engine looks reasonably similar, so I've been following the proceedures in that. I just don't know if the valve clearances for the zeal is the same as the fzr400. I'll phone a bike shop tomorrow and see if they can tell me what they should be.
    Gotta get myself a torque wrench too...

    Oh god, it's too late. He's been and gone and done it. Good luck with the getting back together and going bit!

    If you mean the pliers, they just happened to be on the floor when I took the photo. I wouldn't dream of using them to undo bolts or anything like that!
    They were there from removing the circlip from the chain.

    I's gonna git the race ogranizers to play "Rawhide" when you's on the track little fella!
    If a man is alone in the woods and there isn't a woke Hollywood around to call him racist, is he still white?

    ah...

    well, the actual hammer never touched the bike (well, I might've tapped it with the rubber coated handle a bit). I used it in combination with a block of wood to loosen the camshaft cover (haven't got a rubber mallet).

    KK, I used some silicone gasket stuff when I put the starter motor cover back on after Death fixed it up for me after my bin. It seems to be working ok, it isn't leaking. I'll have to see with the camshaft cover though, as it's not just a thin gasket. I'm kinda hoping I can just put the cover back on and all will be well, or maybe use a bit of silicone in combination with the original gasket.
    I dunno if it's a high pressure area, I guess it might be. If I put it back together and it leaks, I'll know I need a new gasket...

    I've got a question for anyone that knows about adjusting valve clearances.

    The recommenced clearances are:
    0.11mm to 0.20mm inlet
    0.21mm to 0.30mm exhaust

    the exhaust clearances are all within acceptable limits (mostly all 0.254mm, one is at 0.229mm) so I guess I don't need to touch them.

    The inlets are (in mm):
    Code:
    cylinder:       1             2             3              4
    clearance: 0.127 0.152   0.102 0.076   0.076 <0.038   0.102 0.127
    Going from the measured clearances, I have to adjust the valves in cylinders 2 and 3 and one of the valves in cylinder 4. Or is it wise to just do them all at once, even if some of them are within limits?

    Also, I think I read that it's the valve seats that wear more than the cam/cam followers and hence the valve clearance generally reduces as the engine wears?
    So should I try to set the valve clearances that I change to the upper limit in the acceptable range?

    At least you got some answers... the yamaha mechanics in Pram asked me if JR's bike was a 400 or a 600 when I took it there

    Hence the comment as a universal tool
