PostPosted: 13:47 - 05 Jul 2007    Post subject: Ticking head. Reply with quote

ok im getting my bike serviced next thursday as there is a quiet ticking noise coming from the head, more noticable when cold at low rpm. Im having the valve clearances reset, he's checking the CCT, balancing the carbs, checking cylinder compression and replacing sparkplugs (had oil and filter done a few weeks ago).

So my question is, could riding the bike until thursday damage the engine if its just the valve clearances that are out? theres no loss in performance, and too be honest the ticking isnt too noticable?

any help appreciated Razz Karma

It does sound like the valve clearances. If they are only out a slight amount, riding it is not a problem.

As long as valve clearances are ok at the normal riding temperature, then if they are a bit noisy when cold it's nothing to worry about. The normal "don't thrash it until it's warm" applies really Smile

most likely the valve clearances. Cam chain would probably snap before long if it was that.

Mine is in for a service today, has had the tappety noise for over 1200 miles, told the dealer when it started but they said it was fine and i will kick up a big fuss if they dont check the clearances as its really the only reason im letting them service it Wink

If it's a Honda CBR600F then it's the CCT that needs replacing (£50)

If the ticking still persists when the bikes warm it's a new camchain (£100)

You can pop the CCT out yourself and clean and put back in, don't quote me but I think you can use brake fluid to clean the CCT.

Cheers toby, the CCT has been replaced before, but at 38K miles i suppose it could be it again, but the noise does persist when the bikes warm so i now think its the cam chain which to my knowledge hasnt been changed before, but im guessing it has at some point.
So il get him to have a good look at the cam chain Thumbs Up .

Also if it is the CCT and cam chain instead of/aswell as valve clearances that need sorting, what effect could riding it until next week have? if it was your bike would you not ride it because of this?

Erm if it's ticking when warm I wouldn't risk it mate, how many miles are you thinking of doing? I'd probably van it to the garage.

It's £25 for a cam chain toby.


Yeah thanks for that Jamie and how much for the mechanic to fit it as well?

Could you find me a VFR750 camchain for that price as well? Very Happy

Ok i took it in to the mechanic early, just to get his opinion on the noise,and to my relief,apparently it cant be the cam chain or sprockets as the noise isnt coming from there? he also said that the noise is hardly noticable and nothing to worry about and that the service next week will sort it (got new CCT for £30 anyway so might aswell fit that to), so maybe its just me being paraniod an its just slight valve noise? (im new to 4-strokes Embarassed ).

Oh well i guess il find out on thursday Thumbs Up cheers anyway people Wink .

Er ....... if you have gone through a cam chain and its new enough to have a warranty then there is something drastically wrong inside the engine.

Cam chains should last years.

I've got the same kind of problem on my sachs and its booked in for a service in a fortnight! so do you think a 12 mile ride to the garage would be ok?

Thanks in advance

12 Miles , take it easy and it should be fine , would be risky if you thrashed it all the way there though.

No its £42+vat + P+P according to Dave Silvers. Also factor in the cost of a couple of gaskets, probably £15-£25+vat and the price starts to look a lot higher.
