I have a high compression 86 Evo which has always been hard to wind over with the starter, I have a bigger starter motor in it. It does wet sump but i have worked out what to do there. Does any one know of a decompression setup I can buy and fit, does not need to be pretty with cables etc just a lever setup will do the job fine.

The commonly available 10mm mechanical units can be fitted to the Evo's.

You just need a machinist who can do the work for you.
