Pressing out/in steering stem

I think I am going to have to seek out a shop or someone who can press out a steering stem from a KZ750 lower triple and then press it into most likely a '04-'05 GSXR lower triple. I'm sure I could remove it but I think it would involve alot of hammering and I don't think thats how they were inserted in the first place from the factory . Suggestions?

Get a micrometer and take several measurements of the stem where it fits in the triple. I did this on my bandit when swapping out the forks, and noticed it is tapered from the bottom of the stem to the top ( wider at the bottom) find someone with an arbor press and press the stem out of the triple from the top down and the opposite side when pressing in the new stem. Also watch for any retaining clips at the bottom of the stem (Suzuki used them on the bandit as well as the hayabusa)

Hope this helps

Look, I can appreciate this. I was young too, I felt just like you. Hated authority, hated all my bosses, thought they were full of shit. Look, it's like they say, if you're not a rebel by the age of 20, you got no heart, but if you haven't turned establishment by 30, you've got no brains. Because there are no story-book romances, no fairy-tale endings. So before you run out and change the world, ask yourself, "What do you really want?"

That means Gus has to dig the press out of the corner. It's burried in a sea of motorcycles right now.

I am in Stone Park and have a press. I have pressed bearings, bushings, ball joints, gears, etc. This sounds like we can do it. Give me a call.

Silly goose at the least you'll have to mix bearings or modify a race DIA.
Chance of it being a straight swap.Go by a lottery ticket.

You can measure it all you want, but if you don't have it out, it won't matter. You have to pull them apart and measure them. I swapped stems once. They were .002 different. One pressed in tight. The other fell through.

I have a press, but don't know when I'll be around the next few days.

.002 makes no sense Greg.The top stem dia is just undersize so the bottom race can fit over it.Is this what you mean??
1 mm .039 would be the next dia. up or down.

I probably should have put this additional info up in the first post lol. I'm not trying to undertake this swap blind. After searching and reading build threads on other forums, the general consensus when it comes to swapping front ends is to swap the KZ stem into the new triple. The other option of finding a stem from another bike to swap onto the KZ is stem length(mind out the gutter ). From what I have seen others attempt, the sportbike stem is too short for the KZ neck, and I can use regular KZ bearings which I need to replace anyway.(I make it sound like a piece of cake huh lol).

What are the chances that the KZ stem will fit correctly into either the top or the bottom gsxr triple? I'd say 0%. You'll probably need to either have spacers made or drill out the triples, probably the former.

you might try the lower triple from a zx instead of a gsxr (the fit may be similar for in-house brands)

Look, I can appreciate this. I was young too, I felt just like you. Hated authority, hated all my bosses, thought they were full of shit. Look, it's like they say, if you're not a rebel by the age of 20, you got no heart, but if you haven't turned establishment by 30, you've got no brains.

Why not have a machinist make a new stem for the triple and the proper diameter for the bearings?

This is the route I went when I put Mille forks on my SuperHawk. I used the 'Priller triples and had a guy make me a new stem. Cost $100 or less and turned out very nice and bolt on with no jabogey spacers or anything.

Good Luck.

Life has no instruction manual. Parts and labor can be impossible to find. Many go down the road with parts that are in need of service. A breakdown is eventual.

Nope.

Sorry. It made sense in my head

Doesn't really matter.

It's never as easy as it seems it should be.

The troubles I've faced are the stem Dia. and frame Dia. might not come as a set standard.

A bushing to fit between the stem Dia. and the larger bearing I.D. Will offer more options.

I do like the kaw front end idea though as you might get luck as said above.
