Project Z going well

[Pancakes]

Nice work Zed! will the Nissan computer have the tuneablity you need or are you going to piggyback an Apex'i handheld or similar? I've always wondered why people don't use some of the car aftermarket computers available, motech etc for worked bikes. Seems the way to go with how flexible the plot points and everything are. Will be watching to see when it's done and all the steps along the way!

I will try it with a piggy back first and if thats not good maybe a standalone like the microtech, I will chat to the guy that modified the turbo to suit the engine and see what we can come up wiith. I was thinking about incorporating a tilt sensor to limit the boost when your leant right over

Bike weight matters, but horsepower matters MORE. I have known DUCATI owners reporting 1600 km's per set...evenly worn. 7 or 8000 km's aint bad compared to that.

Variable vane or standard?

................tilt sensor to limit the boost when your leant right over

Wouldn't the bike frame be constant in regard to the angle of greatest force (it's late but I hope you follow) ie, in a corner where the cornering force is 1G (and downward is of course 1G) it is leant over 45 degree's with the force still going down in relation to the frame (but at say 1.25G's)? You'd need to house it in a gyro or something? You obviously know more about this than me but I'm curious to see what your thinking when doing a build like this.

Couple of guys made one at uni that outperformed a motec, they were looking to market it so will have a hunt around and see if they managed it.

hi classic zed, good to hear you're getting on with your project!
i felt a bit sorry for that pile of bits sitting in the corner of your workshop, collecting dust, when i last saw it.
your "poor old girl" surely desires a company of a turbo charged "big brother" parked next to it

I was thinking along the lines of something that can sense and increase on the downward "G" force as that would be the right sort of direction to measure. As you corner the force pushing the bike onto the road should increase hopefully giving you something to measure, its all theory at the moment but worth looking at.

The guy that built the turbo is developing a system that is giving good results so I will chat to him, but any other options would be good to see too.

My thoughts exactly and I feel the need for a second bike too, it gives me options then,
1, go for a nice cruise
2, go out and rip the streets up

Thats what popped into my head first but I can see you getting G's at the bottom of a hill and then as the load (and traction) comes off the rear wheel boost comes back! I have put a micro-switch on a rally car (well, ex rally car I thrashed around) that locked out high boost in 1st and 2nd so it would hook up on the street. Just a thought.

[classic zed]

Right, its not too pretty but I managed to get it into a sort of rolling chassis and get it to the City of Cycles show along with the road bike

Quite often I'd say, my standard Z1300 has chewed through a pair of tyres in 7,000km, mind you I dont "nana" the poor old girl, I like to wear out the edges of the tyre as fast as the centre. Not much point having a bike if you cant run it hard through bends.

Having said that Im hoping to shed quite a bit of weight from the bike.

The ZX12 rear wheel is away being adapted to take the shaft drive so I can try a 190 or 200 rear tyre on it to see which one works best.

I plan on using a Nissan Skyline Injection system as its already designed for an inline 6 cylinder Turbo engine, everything is timed from the camshaft so I can drive that unit from the original place on the engine that the stock Z1300 pickups are mounted.

Check out these guys... http://www.swingarm.com/ ...they do swingarms for all sorts of things, in all sorts of sizes - including a swingarm for a 'busa that'll take a 280 tyre! I've been eyeing them up for a new swingarm for the Duc - mine's got a bloody crack in it - and while I could get it fixed - there's apparently several other places that they crack also, so proper fix is replacement.

BTW - I like your project! Sweet! I've been thinking of something along those lines, but with a newer bike (ZZR1400). Get a turbo kit from US, and bolt it on... Even got permission from the missus (as long as she gets to have a ride too...). Now we just have to sell my mothers property (6 hectares near Hokianga), and I'll have the cash as well... ... I hope.

.......................Now we just have to sell my mothers..................

Yeah, I would too for a sweet bike but you think she might catch on if you post it on the 'net?

SNORT! Nah - she passed away over a year ago. Tho she might be rolling over in the grave, given I spent some of her money on a bike (PW80) for my 7 year old... And will be spending some more on one for the younger lad, when he's got the art of riding on 2 wheels sussed (just starting to transition from trainers to 2 wheels on pushbike...). She was always anti-bikes - not that it stopped me - gave her a choice between me getting a bike (YZ125A - '74... a long time ago) or a hang glider! Guess what won!

Strange thing was - her parents generation were ALL into bikes... Go figure...

[classic zed]

I checked the steering head angle again now that its on the floor and found it to be 31 degrees

The standard setting for a Z1300 is 26 and a ZX10 is 24 so Iv modified it to 26, hopefully it will handle nicely, quicker in the bends and stable on the straights. The new frame tubes are incredibly strong, after cutting the lower tubes even a ratchet strap couldnt pull the wheel back so I had to cut the top ones too.

It looks so much more aggresive now, Iv cut the guts out of a standard tank to make it fit and once I have the look right I just have to make it hold petrol again.

Nice work there!

I did read how you had changed the angle of the forks. You did not mention anything re trail considerations. I am sure I am telling grandma how to suck eggs here, but just in case, have a look at this as there might be something useful.

Looking forward to following the progress.

If you haven't alreadydone so, have a look at Tony Foale's site and some of the software therein
