Thanks mate, I bought it as a crashed wreck, the PO is a guy called Ken Piper who is an old race-bike builder and mechanical engineering lecturer, who crashed it at 60 MPH and destroyed pretty much everything except the frame, engine and triple trees.

He'd done a magnificent job machining the billet triples for the Yam forks, so I just found a straight set of tubes and re-used them. The bike had done several somersaults, destroying the forks, headlight, gauges, bars, seat, fenders, fuel tank, oil tank, handlebars, levers, switchblocks, footpegs etc. I found the speedo needle under the cam chain tensioner! Ken tore off both of his kneecaps in the process, and when I bought the wreck, he'd only been walking again for a few weeks after almost a year on crutches.

So my contribution really was just a cosmetic resto, the only bits I machined were the brackets for the front fender. I did do a GSXR front end conversion on a Suzy GS1000 a few years prior and that worked well, especially after I had some special screw in fork tube extensions machined to lengthen the forks by 3 inches.

Here's a couple of pics I took when I picked up the bike, that's Ken sitting on it with his newly repaired knees. Cheers, Terry. ;D





I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Terry, 'Golidie" looks amazing and goes as good as she looks I'm sure. Well done sir!

Seth, your build is looking killer too. I'm in the midst of a front end conversion myself. I have to wait on the spoked front conversion though, I'd like the Cognito hub setup laced to my stock front wheel but it's steep pricewise, for me anyway. So I'll be running the stock mag wheel this season. I know, I knoowww..... :( LOL

This is how much I bevel the edges on a stock boot to install the RS34's.

They're in! Much easier with a friend. I just about gave myself a hernia putting them in solo :-/

Those Mikuni's really are sexy looking carbs, I wish now that I hadn't pulled the trigger on a set of CR31's for my bike after I had a biatch of a time with my CR29's, but the only good thing is that they're much easier to install and remove than the Mikuni's.

I've just received a set of OEM K7/8 rubbers, so when I get around to it I'll install the CR's and hope they're easier to tune to my engine than the 29's were. Cheers, Terry. ;D

I've often thought about grabbing a CR rack for comparison. Anybody wanna send me a set to check out? ;) I'll send 'em back to you with a six pack after I've made my conclusions. I wouldn't have been able to fine tune my carbs as much as I have, without the use of my wideband O2 sensor...it's almost cheating.

It's a black pearl (literally black pearls in clear). I certainly can't wait for the candy apple red.  I'm debating a silver pinstripe around the edge. Any thoughts?

I'd encourage the silver pinstripe to separate the red and black. Else, the 2 colors will always "bleed" together visually. Needn't be wide, just 1/16" or so. The shadow is very nicely done.

+1 Seth, that will look brilliant! I've got a "laced" tank in my garage that my son painted for me a couple of years ago, I just need to seal it with POR-15 so I can put it on my bike. Cheers, Terry. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"
