GT750 Steering Stem Mod

[yamahale]

Hi, I know about the mod needed to accept tapered roller bearings, I have the smaller dimensioned one and want to convert. For various reasons I cannot dry fit at this time so I dont even know if it needs it. We have a lathe and a coworker who can run it, but he says the stem has to be pressed out so it can be chucked up. I really dont want to go to those lengths, do most folks just carefully grind them? Thanks

If your lathe is too small then you can just grind them, or most people use a file. On a larger lathe it is an easy job and the entire steering stem can be run between centres. Use a slower speed and you'll find the balance isn't a problem.

I've done 3 x GT550s so far and just used emery tape. Wrap it around the stem and use a to and fro pull method and measure regularly. Doesn't cost much either!!
