You can use the CR480 triples with the '79/'80 steering stem, it fits straight in or use the YZ triples and press the YZ stem out and machine a bush to fit the '79 CR stem.

Machine a bush sounds good.I wouldn't rist the triples of a prolink.

You wont get away with boring originals out to 43mm, 41 is the maximum you can get away with in the standard yolks.

Get a set of 41mm 450 legs, have standard 79 250 yolks bored out to fit, makes a much nicer job and the feel of the front end is better.


37mm bored to 41mm ! you took alot of meat of the clamps there mate.hope that they hold up.

Have done loads of them here in the UK, been doing them for 17 years without a problem. ;)

I have them done on a milling machine with the clamping bolts finger tight.
