Valve spring compressor

[jareness]

I want to change the springs in my 1982 GS1100E. I see all kinds of valve spring compressors out there and don't know which ones will work and which ones won't. What are the stock valve sizes? How big does the c clamp have to be?

Thanks for any help,

I used a c clamp for a while, found it to be quite a pita. Found a cheap spring compressor on ebay and it works great.
Stock valve sizes on that bike is 23mm ex and 27mm in

Same. Cheap one off ebay, and it works great.

Think this is the same one:

Yup. I have one just like it.
Why Mickey Mouse around with a piece of PVC pipe when the CORRECT tool is so cheap and EASY TO USE?

Yup, same one i have. Works great. I think it might work on 2 valve engines as well with the adapters.

Wish I knew about these cheap tools when I did my valves last year. Every compressor I saw was $100+. Used the 8" (IIRC) C-Clamp with an old deep socket that I notched out.

I used a c-clamp,with a spark plug socket i ground the sides off from.And alot of cussing to make it work right.Don't ask me how i know,but the cussing seems to be needed for operation.
