Well, in my over ambition to get this done before heading back to the boat, I bent the lower triple while pressing the stem in

We're on a holding pattern.

I leave you with the mockup.

I have to walk away, I'm too disappointed in myself :-/ At least a new lower triple is cheap. Upon looking at the mockup, I fear there may be not enough clearance from the headers to the front tire as well. Solutions may involve a stepped down upper triple, or maybe what I had originally planned...triples with the correct vintage offset. This was a night of disappointment gents.

Just a setback! Good to get refocused and return with a renewed vigor.

I was wondering about pipe clearance Seth, the Gixxer clamps are 1 inch {25mm} closer to the pipe {tank, steering head}than the stock offset.... Looks like some fancy clamps may be on the cards after all...

That mockup does have the front wheel real close to the engine. Do you have a header or pipes to just wiggle in there to see if it fits/clears? Doesn't rly have to be clamped for crucial clearance measurement

If it clears it could still be a problem under brakes....

sethdhawkins · « **Reply #56 on:** November 14, 2013, 06:22:47 PM »

Understood. Either way, a new lower needs to be sourced. I'll cross that bridge when the water's lapping at my feet. I gotta throw together a stereo for a buddy tomorrow, I'll take a look at it all after. Definitely some close measurements with the suspension loaded... I think that will give me a more accurate measurement, as well as a fully compressed measurement. Time to bust out some more straps

Seth, something else to weigh up mate, there is also a small amount of flex in the forks and frame under brakes, if you abuse your brakes like I do then take that into consideration as well...good luck....

sethdhawkins · « **Reply #58 on:** November 14, 2013, 06:29:44 PM »

Agreed. I put the flexible flyer through the motions this summer. I'm not sure that the flex was noticeable, although I have gusseted the frame substantially. If it ends up being close, I'll rectify the situation. This swap was all kind of a fun idea. Should it be necessary, I can always swap the old frontend back in with less than a few hours labor.

sethdhawkins · « **Reply #59 on:** December 19, 2013, 06:51:21 AM »

Well, it's together.

Very cool bike. I also running 2,25 x 18" front and 3,5x18 rear spoked wheel. Looks awesome I think !

Where did you got the front hub ? And do you know what GSX-R the front end came from ? What year ?? I think it looks so cool! And I love you ripped of the gold, I think it's for new bikes only.

Again REALLY cool bike!

Looks really great...I'd love to swap out my frontend but I don't want to give up the Lesters

sethdhawkins · « **Reply #62 on:** December 19, 2013, 02:03:18 PM »

Hummel,

The frontend is off an '06 or '07 gsxr. The hub is from cognitomoto.com (which is now also producing stems for this swap as well). I'm running an 18" wheel in these photos, and with this tire setup, it may be a little too tall (stock on the gixxer is a 17" wheel). Removing the gold anodize really made the forks look good, but leaves the forks easily scratched

Today, I mounted all the controls and started looking at how to cleanly mount my gauges. I may just run the Acewell right in the middle and mount the AF/R gauge on Velcro, so that it may be removed when not needed. I found the gauge distracting at moments while riding. Sitting on the bike with the clip-ons, I fear I may have to make the leap to rearsets.

RAFster122s · « **Reply #63 on:** December 20, 2013, 05:47:40 PM »

If you polish them you could then have then anodized again with clear. End result will be slightly less glossy if I understand it correctly. But you have to totally disassemble the forks to anodize them.

sethdhawkins · « **Reply #64 on:** January 28, 2014, 07:21:51 AM »

I made a dash outta some 1/4" aluminum stock. I really like it. I'll snap some photos unmounted, when I throw a slight polish on it. Mounting the headlight today and then maybe some wiring.

nice!

I noticed on your fuel tank latch, you have something rigged up. What did you do? Details? I have a similar tank and the entire key lock assembly gone. And I cannot find a replacement. I would really like to know what you did.

Nice looking set up.

sethdhawkins · « **Reply #67 on:** January 28, 2014, 11:08:02 AM »

Mounted the headlight.

Looking great. Keep up the good work. Looking forward to doing one too when I finish my restore.

That GSXR front looks shorter? Is that what the possible clearance issue is due to?

seanbarney41 · « **Reply #69 on:** January 28, 2014, 11:35:51 AM »

Seth, I am about to build a tach mount out 1/4" alu. myself. I planned on roughing it out with a bandsaw and holesaws, then trimming with belt sander, die grinder-mini-flap wheel, files, hand sanding etc. You got any tips n ding this?

sethdhawkins · « **Reply #70 on:** January 28, 2014, 06:59:01 PM »

Sean,

1/4" is really thick, had I done it again, I would've gone with some thinner stock. I used a jigsaw with a fine tooth blade for the majority of the work, an 80 grit flap disk, and some 80 grit on an orbital sander, and many files. I bent the gauge mount for my wideband O2 gauge with a hammer, so it sits on the same plane as my acewell. Honestly, I really have to say I like the results. It's very surprisingly good looking, having not been milled. Tips? Lay it all out with permanent marker, then plan your cuts like a barber; you can always take more off

It'll look awesome on completion. I only wish I'd made a small bracket to relocate the gixxer brake resevoir.

Jerry,

Having measured the forks on both bikes, I can tell you this. Where I had lowered the front of my bike in the stock triples and forks (slid them up to lower the front), the gixxer forks measured the same, overall. I would say, not being an expert, that the length differences are negligible. Especially, since there are length differences in the stock cb750 throughout model years. The clearance issues are entirely brought about by the offset difference between the CB and gixxer trees; the gixxer trees being set closer towards the headstock. If the gixxer forks were mounted in a set of triples with nearly stock offset, there would be zero issue. Who wants to start a run of custom milled trees for this application?

I removed the locking key portion and mounted a hood pin (like for a muscle car hood). The big clevis pin is missing in that photo. I really like it. You have to cut out an area a little larger than the stock key latch area to make it work, out of the fuel door. To mount the pin, I cut the pin down, welded a flat washer to it, then mounted it with a thinner nut to the underside of the stock latch catch. I'd take a photo, but I'm nut sure it'd give you much perspective. If you're truly serious about doing it, I'll take it apart and show you the whole nine yards.

And we may still go that route
