Not updated for some weeks now, to be honest turbo's have been a drag lately. My new forks and wheels on this project both took a turn for the worse ... delays after delays and additional engineering...... then my turbo failed on the Paxo Turbo bike I have ....... simple fix ...yes... but I asked for ceramic coating on turbo , headers and stubby exhaust... when they came back ..... the headers had several small scratches ..... :mad ........ awaiting their return from rework .... I had to take some time away from the garage for my sanity ... :cry

I did mange to dry fit the new rear set on the gear side , will need some adjustment & probably a GPZ750 NA sprocket cover ..... will post pics

I had good news today , my new hybrid forks are closer to being finished ....taken some months to get to this stage and I will soon be the proud owner of an Evergreen billet special turbo :rock

Good to hear gpzfan. I am sure you will be happy with the new turbo from Charlie, and when forks and wheels come together, Happy Days.

Understand about the scratches, sometimes hard to find good work these days.

Looking forward to seeing it together.

It seems this project has been a bit of drain on my enthusiasm , its certainly taking longer than expected..... having done several I should know not to expect anything easy :mad

Those are beautiful, agreed it would have been worth the wait.

Know your feeling, about enthusiasm, I am at a stand still right now myself and am really not liking it.

Keep at it, beautiful work.

This rebuild / freshen up is not all about the bling. I got round to replacing the switches and the pilot cover over the weekend. I had some NOS parts I bought some years back. Not sure if the switches are "100% correct" but the wiring block match and they look way better than the tired old units I had fitted

Despite having ZXR750 yoke I was happy to keep the pilot cover rather than finding another way to mount the lamps. The ignition barrel does not sit right but I like the idea I can look down and still see the old bike DNA

I had some parts printed up just to close of the side opening as the cover sits on the ZXR yoke and not over it as per the original set up

So, if you have been following this thread, you will have detected I have been some what pissed with this build. 1st I had big issue's getting the forks how I wanted them. Turns out my original set were bent .... so I had to source another set from Germany.... all the classic racers were buying old ZXR750 forks for racing .....additional cost and additional weeks delay. When I got them it took months to get them sorted . Previous pictures show they have turned out nice

2nd big issue's to cause me to loose faith were the wheels, I bought some Dymag wheels for the ZXR750 at a great sales price (it came with ZXR750 running gear according to the advert) . Some 8 to 10 weeks later they turn up, all nice and shiny .That's when I realise the wheel has a larger axel than fitted to my bike. I realise the arm fitted to my bike is from a ZXR400 so its a 20mm axel not 25mm as on the Dymags.

That did not seem a big issue, I could add a sleeve over the axel I was thinking. I recalled having an old (2015) email from the original bike owner in Germany who had the mods carried out (I'm the 2nd official owner). He took a week to reply and when he did he said he had also skimmed the sprocket holder by 5mm ..... :shock: ..... shit !!

I had to send the wheel back to Dymag to reengineer the wheel to suit, this took a lot of measurement, back and forward discussions etc. This was more complicated than I expected, in the end I opted for the hub rebuild ....... again this took weeks to resolve and I was loosing heart ( I can't fault Dymag, they were helping me out )


I got an email last night saying the wheel was shipping and would be with me today !!!! :rock

I spent an hour in the garage tonight doing a dry fit

I now need to do a proper chain alignment check (advice accepted) and I think I will need to machine some material from my Motogpwerks caliper bracket ...... but it seems things are suddenly moving after months of stagnation

Some expensive lessons learnt :beer
