Hey all,
Its almost riding time again in the midwest!! actually guys are already on the road.
I am wanting to do a bit of maint on my ride before I crack her out of the cave.  I have a 98 M750 and noticed I have Showa Forks # GD051  were those standard editions on this year and model?  I was just curious.

Post a pic just so we can say for sure, but I'm going to say those are not OEM forks.

Not stock on that bike.

M750 didn't have adjustables.

Those are forks off a SBK.

What's going on with that brake line?

I bought this bike last summer. Trying to get everything in order they way it should be. 
Sorry for my ignorance but whats a SBK?

How long should that brake line be?  It did look a bit odd but I never put to much thought into it.  Probably not to safe.

SBK is a superbike. It's a good thing. That is a much better fork than what was stock.

The brake line not so much especially since you aren't running a fender. The danger is if the line gets worn through by the tire.

You can get something a lot closer for not a ton of money.

Do a search on the forum for brake lines.

Speedo cable doesn't look right either.  The brake hose needs to be long enough not to be stressed at any point of suspension travel, but not so long it could catch on something.  A better photo of the cable and hose routing will help.

Ill take better pics in the morning and post them up.  I was also looking at clip ons but I did notice that my handle bar risers look like a doit yourself job with spacers...

did a bit of reading on the SBK conversion. Since its looking like I have different forks than original how do I determine which clip ons I should be considering. Thanks for the info thus far. I appreciate it.

Measure to be sure, but Monster forks use 50 mm., Superbikes 53.

Trust your measurement over my advice, but if it helps, the GD051 Showas are stock on my '98 916.  Any 748/916/996/998 clip-ons should work, as should the later models (749/999 and 848/1098/1198), I believe they're all 53mm.

Couple of heads ups if you're planning to mount the clip-ons under the top triple (at least the problems I ran into):
- looks like you've got coffin style reservoirs, those will interfere with the bar mount on most clip-ons
- the headlight mounting brackets will interfere with the clip-on's fork tube mounts
There's a ton of easy ways around these issues, from dirt cheap to shiny new Brembo RCS radial master cylinders [drool]. Search around a bit, there are a bunch of threads on these issues.

Thanks guys for the tips. it really does help. I did not even think of those issues.....

If you look at the pic I posted you will notice that I do not have a front fender...Now I know why...I am assuming the original front fonder would not fit correctly on the new SB forks that were installed.  I even went out and bought a used front fender for a 98 M750 and it wont fit....That is why I started thinking something had been done.  I went through a ton of  97-99 pics trying to find a picture of someone with the same style forks....

would it be a good idea to look at some fork adjusters? 

I took pics of the risers that look like someone shimmed them up but just have not gotten down to the office to post yet. And I am leaving for work for a few days. I will post it when I get back..
I would really like to replace the riser because it looks so terrible. That is why I was thinking of installing clipons I thought it might be a tad bit easier but then Doug piped in and raised a few issues I might just run into.. which I truly  do appreciate..

You can use any 916 style SBK or 99 up SS fender. You really should protect those fork legs.

I think the home made risers are to get the standard bar over the fork adjusters. If thats the case you can buy  bars which have a shorter mid section to get the clearance.
