    As the title goes, lots of projects...

    building this turbo bike, kawasaki turbo motor taken out to 810 with forged wiseco pistons, manual camchain tensioner and a garrett T3 turbo, this is what the plenum was for in the alloy welding thread I started :-
    [​IMG]
    I promised lots of people it would be finished this year, but Ive just accepted a new contract that takes me away from my workshop for 3 months solid.

    My "standard" gpz turbo, lots of modifications that are hopefully undetectable to the untrained (wifes) eye as Im supposed to be not modifying this one as it was such a clean example of a original bike. Im taking it to the dyno and expecing about 140hp at the rear wheel so the cat may be out the bag shortly concerning lots of parts I needed for the resto... The exaust system is the easiest to spot job on it, once that shiney tailpiece was a alloy downspout on our house guttering so I span it up on the lathe to clean it, turned a endcap and welded it in place, and the rest of the exaust was homemade too. It will always be a project, since Im always in the process of modifying yet another part or designing the next tweak. At the moment its in pieces getting a bigger diameter charge transfer pipe and a O2 meter. Its needed for security and to make the engine last longer if she reads this, honest..

    This is my other beastie, it was once a 1977 gs750. I fabricated the frame apart from the headstock and front frame loop (keeping them all important numbers..) and pretty much everything has been changed or modified over the years, each piece undergoing evolution as it were. It went through stages of big carbs, turbo + fuel injection and today she stands like this, Id say about 70% through the current rework. But I did get a bit carried away. Its difficult to see from the shot, but wedged in where the airbox once lived is a SC12 supercharger from a MR2SC Toyota, with all custom fabricated manifolds. This feeds a air-air intercooler taken from a landrover up front, which feeds a custom fabricated intake manifold, in fact this is what the current job is. The drive is taken from the left side of the engine, with custom end cases, and uses a intermediate shaft to narrow the drive so I dont have to ride with my knee out, like I see in so many other s/c bikes. The inner drive also drives a gsx-r alternator as the top idler pulley on the belt run to give it a decent length/radius so it can stand 12000rpm lunacy.
    Again fuel injected, using a megasquirt homebuilt fuel computer this time round. Ive taken the motor out to 838, but Im probally going to take it to 911cc because I can get low compression forged pistons easier in that diameter. For power, I doubt it will make anything like either of the turbo's but I dont really care, we've come a long way baby through the good times and the bad as the song goes.
    Im sure when I pretty it up after the work itll be nice, Ive been told by two magazines to get in touch with pics when its shiney once again...

    Besides that I have a xt500 supermotard thats a wip, but no pics, and Im reworking a nova/sterling but throwing away the beetle chassis and fabricating a tubular spaceframe myself. Engine is a RV8 3.9 (but always looking for a 4.6 for the right money ;) ) with a 6-71 blower to go on top (its too big for the 3.9 hence wanting to go to a 4.6) mating to a renault un1 transaxle. I have ideas to make it lpg only as lpg is 120+ octane.. Oh and Im restoring a vw bay window camper for my wife.

    We have some normal vehicles too thankfully. I even take my wifes mondeo to the garage for them to fix mostly...

    Good work man love the look of a well put together street fighter.

    Bet that supercharged gs750 sounds the nuts on open header and the blower spinning up...........:D

    Wow!

    Where do you find the time to sleep? The bikes go over my head (other than realising they don't normally have superchargers), but I'm familiar with the Nova. Hope you've fabricated your own suspension as well as the chassis if you're planning a supercharged 4.6. But it's the way to go - I have a stage 1 and a bit 3.9 in one of my cars and it's not quite frightening enough. To be able to spin the wheels in any gear at any speed - that'll be fun. Love to see pics of that one.

    Is it possible to lower a street bike like you do with cars??

    Malcom:-
    I tend to work 3-6 months a year then take the rest as timeout, so I try to get all my sleeping done when Im away working, plus when Im at home our 20month old son tends to get me out my pit at around 7am :)
    As for the nova, well, at this moment in time it just looks like piles of spares and tubes as the chassis is not welded together (its why I want the tig so much), but Ive got a shot of when it was vw chassis'd. I had put a 1600 ford cvh motor in it onto the vw transaxle, but even that modest lump was too much for the handling and brakes really. I loved the pose factor, but I hated the running gear..

    suspension yes, its to be classic double unequal length wishbones with suspension rockers etc ala gt40 kits and some espace uprights. Transaxle strength is of course a issue but derek bell does a upgrade to make the renault box take 500hp and v8 torque, so when the time comes, and you can easy get adaptors to run ford granada halfshafts on the renault box, which are much stronger than even the renault v6 turbo ones.
    I know what you mean about the v8 being a bit underwhelming (even more so on lpg with a otherwise stock motor), I have as my daily driver a 86 rangerover classic, and although it makes all the right noises it doesnt really like to rev freely. Ive been told by Mrs F to keep my grubby hands off it apart from the usual mot repairs every year so its still std though. Im hoping the cam will wear out soon and the headgasket start leaking (might as well port it a bit while the heads are off..)

    MIGMAG :-
    Yes, it depends on what you want handling wise, lots of clearance makes the centre of gravity higher which makes it twitchy but lets it get right over in the corners but change line mid corner to catch it when things go wrong.

    In the past I had a ft500 honda (the factory flattracker) and that was too low, I got sick of it grinding out and wearing the edges of my boots out in corners. Great for hero stories but a pain to live with and you loose the ability to easily change line mid corner. And we wont mention the time I fell off it because the road lifted my foot into the gearchange and it changed up at exactly the wrong moment. That bike was a abject lesson in how to take a exciting concept (lightweight big single 4 stroke flat tracker) and tame it and sanitise it until it became so boring you could fall asleep riding it.

    I have a ktm duke at the minute its a total hoot to ride but was wondering what it would be like if I dropped it on its ass.
    I dont ride that fast and anyways it doesnt like being layd in the bends its more slow in and fast out.
    Or I could cash it and get one of those 500 rapter quads on the road and drop that.
    wadya think Mr fluff???

    I love them ktm dukes, in fact I was in a showroom at a ktm dealership with money and the intention of buying a brand spanker one to ride to work on. Until the question got round to my then weekly mileage which at the time was around 1000+ miles a week. The dealer advised me the ktm wouldnt last very long doing that sort of trek the way I rode. So I bought two s/h big jap 4's instead so one could be in the dealership (no time to work on them myself back then) while the other was in use.
    They do go right over since Ive been trailing one watching it grinding its footrests off on some long sweepers and in the racing they grind the swingarm! but the guys who I went out with had soft supermoto tyres on their bikes and 6 pot calipers gripping huge discs (and lots of motor tuning..), and down a twisty lane they are bloody mental in the right hands.
    Dunno about the quads, I steered clear of them since every time I seen one crash it ended up trampling the rider too and when we used to go motox we often had to lift one off the top of its rider when it all went wrong. And having ran a sidecar outfit (you may snigger but it ran a 14 on the drag strip) on the road for a bit I imagine day to day its a bit like that, in that when it rains you get wet still and you still get stuck in traffic because of the extra width...
