Valve spring compressor

[Bill Thomas]

Which could be useful if the head does not need to be removed for some reason.

I had to change a spring on a car once , With out taking the head off, Just put a bent rod through the plug hole. Another Bodge .

Russell, That is a fantastic idea, perhaps you could put it into production, and perhaps call it a "Firefly" or something similar.

Some info here; valve can be kept on the seat by stuffing rope in the spark plug hole -

On a Vincent it is not really an issue as the rocker collet on the valve just sits in the top of the guide, I have cam timed an engine using very light springs (part of a GM LS engine kit for changing a cam) and then changed them out for the real thing. The intakes stayed put as they had new seals and IIRC i could just pick up the Exh with a pair of needle nose pliers and slip the keepers in. Wasn't a big deal. If all else failed you could pull out a rocker and hold it up down the tunnel.

Enjoy it Russell, but not on public roads!

............ Vincent heads. Will not be needed on my next project, bolting an 80cc 2-stroke engine on to my mountain bike. View attachment 33660

How about this one built by Norton Owners Club member Barrie Fairfield. Not legal but with the engine, electric motor and rider pedalling you might be able to outrun the law.

It looks like something the Spanish Inquisition would have used.
