Valve lifter question

Postby Rgray » Sun Oct 15, 2017 1:32 pm

Lots of nooby questions here, sorry for that!

While I`m messing about with my bike, I thought I would also adjust the valve lifter.

Found this great vid on youtube...

Only problem is that as soon as the adjuster arm touches the little tap on the rocker arm it wont budge.

Is there a possibility my bike is fitted with a stronger valve spring or something? the valves move up and down as they should when I crank the motor but I cant move them with a large screwdriver, let alone the valve aduster. They are realy hard.

Whats going on?

Looks like the pin on the mechanism has squared itself off so it sticks on the corner.

I thought it should be harder than that. (Being able to file it). Nev

Yes. That was the supprise!

It was quite soft, maybe an aftermarket part?

I`m pretty sure it was flat on the bottom because its been wrongly adjusted and I think its been smaked by the rocker arm constantly.

It was re-registerd in the early eighties, so I imagine it was restored back then but been off the road the last 12 years. I`m not sure why though because apart from the massive leak it had it runs great :)

There are 2 wrongs on the youtube picture; first there should be a oilstop washer before the main plug, second the angle of the lever must be before top and pressed just after top of the cable line.
So the cable is adjusted to that and not the otherway around, that's what could go wrong :) .

Yes, Mine had the oilstop washer and the lever on my handlebar didnt have enough throw compared to the cable so I shortend it a little and just used a solderless nipple.

I've never seen that video. Great to see people going to that kind of effort. Is that our Steven Carter?

I guess not - there's no insulated leather cylinder cosy!
cheers
