Valve Clearance Costs.

[RS125_Tecky]

following on from my previous thread...

Someone said at 24,000 miles they are due a major service.

The bike is on 20,000 miles and he doesn't have proof that the valve clerance was checked at 16,000 miles although he assures me it was done.

So basically I'm thinking of getting it to a dealer ASAP for a valve clearance service.

How much would this cost for;

a) they sure measure it but all is ok?
b) they measure it and need to adjust?

Help appreciated, cheers

I had quotes for my GPZ adjustment of valves ranging from £360 to £70

I took up the £70 one as I know the mechanic is very good,

he even collected my bike for free too!

If you're local to midlands, pm me ill pass on his details

Hi

Very much depends on the bike. Shimmed valves can be a pig to adjust (on many bikes the cams need to come out) but rarely need touching. You measure the clearance, take the existing shim out, calculate the size of the shim you need, buy it and replace it (probably about £3~£5 per shim, although some places will part ex them).

Other bikes have screw and locknut type adjustment (such as Simples GPZ500). These are far quicker to adjust but need doing far more often.

Given that the interval is 16k~24k this suggests that they are shimmed valves. Expect a bill of a good few hundred pounds.

All the best

R reg GPZ500s, which is shimmed not lock nut kickstart, according to my haynes anyway, Varadero125 is the screw and lock nut, I could do that my self , but didnt fancy moving shims around.

Hi

Didn't know they changed that. The older GPZ500s are screw and locknut and were up to 1996 at least).

All the best

I would expect an independant bike shop to charge in the region of £80 to check the clearances and replace any shims that are necessary.
You could always check them yourself, just for peace of mind? Costs - nothing, perhaps just buy a set of feeler gauges and a haynes manual.

Hi

Checked on the Kawasaki US web site and that has the parts diagrams for the GPZ500 (Ninja 500 they call it or Ninja 500R) and up to the latest model shown there they are screw and locknut.

All the best

I just paid £480



But that did include genuine honda chain + sprockets, cush drive rubbers, full service, braided hoses and a new clutch

Kickstart how do you know about the valves on your gpz? where are you getting that they aren't shimmed from? my haynes say its shimmed, ive jsut paid to have it re shimmed and every link on google says shimmed....


my valves were out, and it deffinelty increased the rattling.

Can anyone else add any more useful info on what to listen out for engine wise?

Basically, a bit of rattle from the top end may not be too much to worry about, as long as it isn't excessive, but if you hear a regular deep knocking, walk away. Pull the clutch in and see if you get a change in the noise, if you do it's mechanical noise from the clutch / transmission, if not it's likely from the engine. Make sure there's no white smoke from the exhaust when you blip the throttle.
