Hi all,

Bought a new bike, didn't check it properly as it's been sat for 2 years doing nothing.

Anyway here are the problems,

Bike will die after revving hard.

Decided to full service it.

Oil was a touch milky =Changed oil.
Cylinder 4 spark plug has what might be oil residue=changed all plugs.
Done the valve clearances, a few intakes out of spec=Adjusted.
Clean air breather full of oily greasy carbony gump=cleaned.

What's worrying me is that spark plug.
How often to valve seals or rings go at 15k miles? Could it just be crappy from being stationary for nearly two years?

What would your course of action be?

What is the bike ? I'll assume it's a ZX6R because that is the main focus of the forum, but what year is it ? Any aftermaket "stuff" (jet kit, power commander, etc.)

First get it running. After a few hundred miles go over it again and check everything.

Sorry my bad zx6r 2006. Remapped with micron slip on.

Yeah get it running and recheck sounds reasonable. I'm thinking it'd be pretty unusual for an engine to bust a valve seal or ring at 15k.

If you have any aftermarket mapping, that might be the problem to why your bike is shutting off after revving. Try loading a new map or just unplug it and go back to the factory ECU. That will probably fix it.

Cheers scorpio. Unfortunately I think it's remapped directly into the ecu. I'll take the rear fairing off in a min and look for a power commander.

The offending plug.

The injector may be hosed up from sitting...... if it doesn't seal all the way and just continuously sprays fuel into that cylinder that's a long term problem. It would eventually wash all the oil off the cylinder wall, possibly causing scoring from the rings......

Stuck injectors. Worrying! I'm going to dump some seafoam through it and see how it goes. I duno if the stuff is snake oil or not! That plug looks pretty nasty right?

It does look nasty! If that bike was stored for two years without a fuel stabilizer being added and run through you probably do have clogged injectors. What did the fuel and inside of the tank look like when you acquired it? Go ahead and give the Seafoam a try as it won’t hurt anything, but I personally do consider it “snake oil”.

DO NOT any type of injector cleaner, any stronger than recommended. Very aggressive on seals and gaskets.

Fuel looked a bit off but it wasn't clumpy which I guess is a small light shining.

Will clogged injectors possibly sort themselves out with a good run through?

Will seafoam damage my seals??

Possibly. You may need to pull them and have them cleaned. You could need to replace. This may also not be the problem; it is however a good maintenance practice.

Any solvent applied too strong can dissolve things you don't want it to.

Just seen i can get primary fuel injectors for 20 pounds. I'm tempted to just buy these and throw them in before running it.

Your profile doesn't note where you live, etc., this is actually very useful info when trying to assist you (or any other member). But I'm inferring you're in dear old Blighty since you referenced the Pound, as in Sterling. First off, dump the fuel, all of it! Fill with fresh stuff... hopefully with non-ethanol.

It also helps us if we can get a rough grasp of your mechanical aptitude. Plus, a general notion of your spanners, etc. When you do get it running don't rap on the throttle... at least until you are supremely confident that your baby if healthy.

It very well may serve you to run a compression test on all four cylinders. The photo of your new spark plug pains me.

You also might wish to tap Rivers on the shoulder and run this past him He's our resident Yoda/Obi-wan/curmudgeon. Don't waist his time if you go this route, he does not suffer fools kindly: "... There is do, or do not, there is no try... ". Include all meaningful photos to further your cause. Tell him in concise detail exactly what you've done/not done. BTW, DETAILS ARE IMPORTANT. The sounds and smells your 636 is experiencing, etc.

Meet your new best friend:

Also, for the rest of the peanut gallery, Sta-Bil offers up their 360° that one can run on a regular basis. I will warn about the smell; it wafts a peculiar scent... from the can's tip (not the bottle). There's a curious bit of chemistry involved.

And in the future, if you don't ride regularly - every couple of weeks, or so - you should use Stab-Bil in your fuel system as directed. And quite literally keep the tank filled, you want as little air in your tank as physically possible.

Good luck, mate. And do keep us posted on your progress.

Hi zedex
Thanks for the response. Yep I'm on the rainy side of the pond🏴󠁧󠁢󠁥󠁮& #xe0067;󠁿.

I might of confused things a bit, that plug was from the cylinder and replaced with a nice new champion plug. In fact all 4 were swapped out.

Mechanical aptitude... Reasonable? I have an engineering degree so I'd like to think I can pick things up but I'm obviously still learning. Which is half the fun in owning a bike right?

Thanks for the service manual link.

As a bike update, she should be running next week. Waiting for the fuel tank to return from the painters after I made a Royal balls up and let it fall over with petrol in....
