Been researching my butt off as of late with 750 Turbo upgrades and mods. Looks like I'm going to need a different C/S sprocket with less offset as the turbo and NA engine sprockets are not on the same plane from the factory. Since I plan on running a cone filter right on the turbo due to the VFR speedo drive being where the turbo airbox is plus a different than stock exhaust system, I'm going to enable race mode, add a BOV and AFPR. Luckily for my tiny budget I can mock-up the engine before buying all the add-ons. I'll probably aim for 12-13psi which according to 750turbo.com is good for 120-125whp or somewhere in there.
First I need to wrap up my the side project on my Kz1000.
I forgot I made this thread but will try to keep it up to date as much as possible. I really need to read through the thread and figure out exactly what I’ve covered and where I left off.
I got tired of moving it around and got some time freed up from working on other people’s bikes so time to get back on it. I have been collecting parts since the last update and been daydreaming/scheming on how I want the final product to look like.
I had a member from another forum put in way too much work (which I greatly appreciate) shortening and threading a Triumph axle for use with a Ducati 916 rim. Both the Vfr and Triumph sprocket hub fit but the Triumph unit seems to keep the chain line straight when I have the required 3/8” offset front sprocket.
Since swapping to the hybrid rear-end mashup, the caliper bracket I made to fit the Brembo caliper with the stock VFR wheel no longer works. So I found just about the smallest caliper I could and set out to remake another bracket.
Now the back of the caliper clears and the eccentric can rotate 360°.
I bought a lightweight titanium Ladybird muffler several months ago to replace the heavy D&D. The Ladybird had a few dents and dings but was nowhere near the price of a new one. I ended up shortening it 5.5”. I cleaned up the cut end and now the only telling sign I did anything are mis-matched rivet styles.
Finalized the muffler mounting. Made up a simple little hanger. Only thing I may do is shorten the exhaust pipe itself to drop the muffler outlet away from the bodywork.
Thank you. It’s hard to believe it’s been 8 years and it’s still not done. I keep changing my mind and parts. I guess this is why people make a thing called a “build plan”.

Believe me, I understand. The Hedgehog took me at least ten years; far too long! It's funny how silly things like family, jobs, and other stuff have such an impact on something really important like bike building.
I decided that some self-torture was in order so I set about working on the wiring again. My first attempt was modifying the original harness but I abandoned that. Now I’m trying to use a Zr7S harness since it uses a newer junction/fuse box arrangement and the bikes are loosely related. I still have to modify it to adapt the Zx14 R/R, Ex650 LH switch gear, Zx12 RH switch, DFI sub-harness, custom gauges and a gear indicator. I’ll get there but it’s going to take a lot of time.
Thanks. I’ve been doing a LOT of side jobs so I was able to pay down some garage funding debts. I’ve started taking in less jobs and want to get back into my own projects.
I originally wanted a Stack tachometer with built-in digital speedometer function but after waiting several weeks with no delivery date available, I cancelled my order and went a slightly different direction. I bought a single function Stack tach but added on a Koso speedo unit. That meant re-laying out the gauges. I added an indicator light for the FI fault warning and a shift light (now needed with the standalone tach).
It’s quite bulky from my previous 3 gauge layout but it will serve its purpose well.
Set about finalizing the Ducati front wheel swap. Turned some 5mm mock-up caliper spacers since I’m using 320mm rotors from the Duc and not 310mm stock rotors. Ended up using a 5mm spacer to move the rotors out and 3mm shim between the fork and caliper bracket to move the calipers in. Rotors are almost perfectly centered in the calipers now. I have the wheel spacers turned up but I think one’s slightly too short and I’m worried about fork binding.
