Valve Clearances?

[Benson_JV]

Hello all

I've enquired with a few garages and I'm awaiting prices but what would you expect to pay to have the following done on an IL4 (CBR600FW) and would you bother doing it yourself? I'm happy to and have always serviced the bike myself but delegated larger tasks. With a new sprog I could do with saving the pennies by DIY'ing but frankly, cannae be arsed.

Chain & Sprocket
Valve Clearances (it were a bit ticky last time I rode it, these are slightly overdue by now)

Ta.

It's a good half day work I expect, could easily be around £500
Checking them yourself is generally do-able, if they are out and you are needing correct shims it gets more daunting.

I paid half of doggone's estimate (may have been £150) to have the ZR7S checked when I first got it, but don't recall how many hours of labour that was (maybe three, thinking about it -- no adjustment needed, worked throughout the time I owned it so who knows).

Via email you could be anyone. I'd pop down, and build a rep with, a bike shop you trust and get them to listen to it.. discuss mileage versus what the manual suggests.. running performance/cold starts etc.

To me a decent shop wouldn't do that much work if they didn't think it needed doing. Bike would take up the bench when smaller jobs could bring in quick cash, not to mention taking one of their mechanics away causing a back-log. Time is money.

On the subject of money you could end up spending a lot, so be careful who you go with. Get an estimate of cost and how long they'd need the bike for before dropping it off.

If stripping it down and taking it in a van is an option then that might save a whole bunch of time, or riding it without anything but essential bodywork. Most of the job is taking away bits to get to what you want, but wouldn't bother if they don't think it ad make much difference -- and, in truth, a decent shop shouldn't charge you a great deal to remove fairings as someone good enough to work in a shop should have a good idea of how most bodywork is put together anyhow.

Usually 2 half days. One to measure and rebuild (assuming you want to use it in the interim)and one to fit the shims.

Make sure you note the sizes of the shims on each valve when finished so you don't have to strip off the cams the next time you need to do it at the measure gap stage.

Thanks for the answers thus far guys, much appreciated. As expensive as it'll be I'm leaning towards taking it into a garage, will get a few quotes and see what's what.

Cheers all.

Its a Honda 600, you could probably get to 250k and not have touched the valves... and be alright.

Sprockets and shit, get it done when you are getting the tyres changed.

I had to get a tyre today and the closest place was somewhere I've heard called Mickey Steal-Yer-Notes.

While I was there I asked how much it would be to have the valves clearances done on the ninja, (expecting about £400-£500), I was told £200 total

Also on a side note, I've made the move from fuck-all-grip-in-any-conditions BT023's to PR4's, I'll get the back wheel done on Monday as they didn't have the right size, but I was pleasantly surprised at how cheap they were, (£240 for both tyres)

[Benson_JV]

Interesting info, perhaps it's not the valves at all then. I admit to knowing not a fat lot about engines so perhaps I'll just get the other jobs done and then see what's what there with the tick tock.

Cheers all

Some manufacturers check compression. If compression within tolerance it can negate phaphing with feelers and needs for gaskets.
Then check again at next major.
Assuming your not experiencing loss/lack of power currently.

Changing a chain and sprocket pair isn't too difficult in my experience- with some chain / sprocket kits you get a tool to join the new chain too. It's usually not the best quality tool but it should suffice for the one use - look on it as a once only disposable thing.
