Default Valve spring removal

I've done plenty of broken spring replacements in auto engines by simply airing up the cylinder and using the spring compressor. Is there a way for this to be done on a TC?

Even with special tools I would think clearance issues would be insurmountable, but if anyone's done it I'd love to hear from them

Thanks guys

I have not done it but what have you got to lose by trying? Plenty claim to have done it this way and if you have experience doing it, worth a try. Two photos are attached; one is the caveman approach and the other is the Goodson tool.

If I remember correctly the Goodson tool is quite expensive

Yup, about $160. It's the old time vs money trade off and a subjective call made by the guy with the problem.

Thanks for the heads up on that Goodson tool! Gonna check with the guys at my dealership and see if any of them have it. If so I'm sure I could borrow it for a Sunday.

Don't want to yank the heads right now if it's not necessary. Planning on doing that at 80-100K for a going over, but right now I'm not dealing with any leaks and don't want to tempt fate : )

Also, that poor mans option is something I'm considering (with minor improvements) if the tool deal falls through. I'm going to be installing some S&S Beehives for some 585s, so I'm not even sure if special adapters will be needed...

Thanks gang! Any input is appreciated.

If shop air is an issue, you can stuff clothes line (1/4. or 5/16") into the cylinder and turn the motor over by hand to tdc and it will hold the valves in position... Works very well without damaging anything....

I've got air, but that's a cool tip. Thanks.

We never purchased one of those tools, as we pull the head off the bike in order to check things over at the point of spring replacement.
