Bragging rights

Sorry moderators, move this if you want to.

Rather than derailing jays joys with his kawasaki ( we are here to help, right ? ) I have copied MB's brag to here. Love his kitten by the way.

Valves may well clash but never 'tangle' with pistons, hence why one turns a camshaft slowly using a hand tool when one is working on the valvetrain. Turning in this fashion means that you can feel if there is contact and thus avoid damage. It does not matter if the two come in contact with each other using this method SO LONG as one is not a muppet and actually stops turning in that direction.
It doesn't matter whether it's a 4 stroke 125, a GT550 or a V8 Ford this applies to any vehicle (even better if you have a non interference head). Turning the camshaft is not the issue but the speed at which it is turned and not forcing it when there is resistance - which could mean any number of things, not just piston valve interference.

I feel that this thread is becoming derailed. My quals are more than 35 years both tinkering and being paid to tinker on engines some small (eg Stihl certified repair technician, amongst others) and some that are bloody huge or expensive, or sometimes both, but mostly bike engines. I built my first engine when I was 13 (a BSA C15 that came in a mess of boxes), I'm about to strip the heads off my 4.0l V6 SOHC Ford (see if google will tell you how many mechanics you can find that are willing to tackle that particular model!!!) and you won't find me regurgitating 2nd-hand googlefu - any OP can find that kind of info. If you look hard enough you might even find a couple of my rebuild project threads on BCF.
How about you Bikenut? Care to share your extensive mechanical background with the folks of BCF?[/quote]

My comment early on in the original thread still stands.

How eccentric :D , see jays thread for the pictures and explanation.

As to MB, he wont have crank timing gear or push rod problem on the Ford, unlike the BSA I suspect.

Not wanting to add fuel to the fire, but MB has not replied about the BSA crank timing gear or push rod possible problems, may be he's just not bothered, can't remember, cant find out what I'm on about via google, or just has a very poor memory.

What is it that's said about the 60's, I just cant remember.

I'm sure those in the know are smiling after reading this, keep shtwm please and lets see what he comes back with.

I have a funny story about a mates c15, but that's for later, insects and aliens and his dad, enough said. :D

As to jay, I bet he is dizzy by now but I hope he gets his kwak sorted. He did say he bought it after a year and a half hybernation, so where any valves bent during its awakening, I hope not.

Will look for his original thread about it.
