Re: Project Yamacati
Ernest built the first yamacati I've seen..then I saw Targets which is a very nice example too. I look foward to your build. Ernest had a YZF750 frame, 1183 stroker motor, Ram SSSA and A LOT of trick ass bits.

Re: Project Yamacati
Hi, have you got any links to Ernests build? I'd love to see that.
Yes this is a great forum, i've learned a hell of a lot since coming here, totally priceless info when you're doing a project.

Re: Project Yamacati
It's been a while since my last pic update so here goes.
As mentioned earlier i managed to fit the 5EB R6 swingarm very easily, on a 3TJ all you need to do is shave down the pivot point on the arm, ream out the chain side bearing hole a little deeper and insert new bearings, after that the stock 3TJ pivot bolt works, it has the same OD as the R6 pivot tube ID. As mentioned elsewhere you need to remove more from the chain side of the tube to keep the wheel centered on the frame, but it really is nothing hard.
You can see my alignment laser hitting the center of the back tyre and the centre of the shock/frame.
I have used the ZX6R sprocket on the front, thanks to advice on this forum the chain alignment will be perfect, here is the laser on the sprockets...
I had to notch out my frame a little for good chain clearance, this will be running a 525 chain...
For the shocker i had planned on using the R6 shock, but it was just way too short and would need a hell of a lot of modifying to work, so i fitted my thundercat shock and made new bones for the pivot. This needed spacer tubes on the swing arm and it needs tidying up and dressing, but you get the idea, this is just the mechanical mock up before i tear everything down for final assembly.
Also in this pic you can see my R6 speedo sender, i drilled my trans casing and made a mounting boss for the sensor, then chemical metal'd it into place, it seems to be sealed pretty well, we shall see.
My R6 clock conversion, everything works, the fuel light works too which has been a problem for others, i just fitted the R6 sender into my 400 tank, job done. The tacho will be sorted when my signal divider arrives, i found this part of the conversion very simple, it only took a few hours to wire the whole unit.
My 996 mirrors and screen now fitted, everything needs painting and i'm going for a tint on the screen.
Just need to plumb the rear caliper, it's all R6 back here...
So the project is coming along nicely, well chuffed with the rear end now...
More updates coming.

This is a link to some pictures I found online

Heres an a little from what he said when i told him how much I liked his build on another forum, we were talking about the YZF 750 6 speed swap..
"Yes, that is my 94 yzf 750 with a 1183 cc, titanium rods, super big vavle head. The front end is off my old 94 SP that has been gone through by Olhins. The swingarm is a one off magnisum RAM swingarm. They don't make it for the 5 valve motor bikes. That one is up to 2 inches longer than stock. It is all 916/ 996/998. Gauges, tail section, and all dymag carbon wheels with titainum sub frame."

Very nice and knowledgable guy. Builds some seriously SICK bikes.

Re: Project Yamacati
You're not kidding, that thing is amazing.
Re: Project Yamacati
The next mod for this bike is fitting a Thundercat fuel tank, the FZR400 one is just too skinny on this bike. Believe it or not the TC tank fits the frame lines better than the stock tank but there are mods to do.
Stock airbox is a no no and even with these socks fitted it comes close. The rear mounting point doesn't fit at all so that will need custom fab work. Today the best i could do was create a space for the tank, so i had to relocate my rectifier upfront and reroute my harness to leave a suitable gap for the TC fuel cell.

Re: Project Yamacati
Another update, i got the Thundercat tank mocked in place, it still needs the rear mounting sorting and a few cosmetic details but it fits the frame much better than the stock 400 tank did.
Looking forward to getting everything into paint now.
Also got my Acumen digital gear indicator in place.

Re: Project Yamacati
Hey looks awesome ,Is the tank from a yzf 750? If it is and does fit well I'm going to get one for my bike .The r6 tank I got looks like it's going to be a real hassle
Re: Project Yamacati
It's a Thundercat tank, and fitted the frame better than the original FZR400 tank did, it just needed a new rear mounting bracket making which was very simple.
Re: Project Yamacati
Sorry for the lack of updates, been very busy with other stuff.
The bike is now 100% finished in its fabrication stage, R6 swingarm/wheel works well, as do the R6 clocks, everything now works as it should, so before tearing the bike down for its final paint i rode it today to make sure everything was ok and i'm pleased to say it's all perfect.
Next time i post it up it will be in its new colours and i will have finished all of the little jobs.
