Well, It's been a while since I posted. I was out of the country working. I changed my mind about the front end. I decided to go with a modern GXSR front end instead. I really like the look. Added were:

GSXR Front End
Benjie Oil Tank
MAC Exhaust
Joker Points Cover
Joker Clutch Cover
Joker Side Mirrors
Dyna Electronic Ignition
Rick's Rectifier/Regulator

Very nice bike and good work.
Will like to see it painted.

What did you do to convert the steering stem from the R6 to fit the Honda?

Thanks Rocket..... the stem is a tad bit smaller. I placed a shim in there to make it work. Its in there pretty tight.

Cool, i didn't need any shims, just a decent press to reinstall it. Whats your rear rim size mate.? 17 or 18.?

There was a member here who heated the stem and stretched it to fit. I wanted to do that too, but I don't have that kind of heat and tool to do that. I couldnt find anyone here in AZ to help me either so I had to shim it. The rear is a stock 17, I wish it was an 18 though. I don't like the way it looks.

I actually like the 17 on your bike because you've managed to find a higher profile tire to fill up the rear of the bike, looks good.

The bike is pretty much done except for paint. I've been overseas a lot. I replaced the seat with a seat I ordered from the boys from Dime City, also added a new headlight. I had some issues with the carbs leaking and not running smoothly. So I ordered bigger jets and new gaskets. The bike runs pretty good now, but it needs to be fine tuned. I don't know how to sync carbs so I'll have to take it to a shop. I also have to find a way to mount a steering stabilizer on it. I want to thank this website for all the info. I've learned so much here.

Donny,

Compliments to you on the build.  It looks great and the GSXR front end looks awesome.  You will love those radial mounted brakes!
