Is there a need to do valve clearance for 4 strokes bike anyone?

[Demon]

Usually no need to VC till your head gaskets leaked..Then might as well do a VC and change timing chain as the top block needs to be removed. I did for my 05 R6 and Super 4 Ver S.....Cost not more than $300 for both bikes.....

 

The valve clearance can be totally off but the head gasket can still be in a perfect condition, and vice-versa is also true.

 

On most bikes, you do not need to open the top block to gain access to the valves as there is an opening, commonly known as valve inspection cover.

Well said bro ... Bottomline is check ur bike manual, under e peeiodic maintainence, refuse to oblige then its own fault... Those who dunno, pls get advise from good mech.. Dun only hear from 1 opinion but then if know nuts bout bike, how to anal-yse e feedback given, will only make urself conpused further lolz...

 

Valve clearance, tensioner, timing chain, rectifier, coil etc all got lifespan, dun service/change then good luck... Alamak i type alot lah, sorry to e pros who disagree to wat i just stated but who cares lolz...

different bikes got different valve clearance, need to check in the service manual.

Mind sharin è recomended wkshops to adjust valve clearance for class 2 bikes

[dark_angel]

depends.

1) how old is bike

2) what is the milage

3) overall status of bike as if most parts abt to give way, better to scrap.

4) cost for VC justify for the bike given for the above 3 condition?

Did mine valve clearance at sporting when reached 45000km, workmanship charged was $150, bring my own rubber gasket & tensioner. It's good to check to ensure. Mine FZ1.

My Spec 3 is 9.5 years old, 77k mileage. Need to do valve clearance anot?

[Pizzaboy]

Some mechs i spoke to said VC to be done at 100k km else dun waste time & moolah$ on it.

I've read many post on foreign web giving feedback on valve clearance check esp those americans, some claimed that gap was out mostly on intake side and some said none need adjustment at 30k km. It's up to individual who deem the need to ensure it's health. At 100k, actually suppose to replace timing chain, tension and guides as a set. Inspect the cam spocket for wear and replace if necessary.
