It is very similar to a supercharged two stroke, a design I've always liked.

    I thought that there's a lot of stuff going around and around and a few more valves etc. Like the regenerative braking stuff (cool gaining something from waste energy) - bet it's got pretty good engine braking...

    In the video there's only 2 cylinders making the power with two compressing the charge. Is it actually making the same (or more) power as a normal 4 cylinder with the same capacity? I may be simple but I'm struggling with that bit...

    yeh, not sure how effective the regen braking would be, depend on how heavy an air tank you need to haul around. There are flywheel kits out there that are relatively bolt on, and manage to store around 60hp for 30 secs and only 50kg or something...

    yeh would be the same (or close to it) as a 4cyl, as the power pistons are firing twice as often, and compression ones not at all, so same firing per revolution.

    Ah, that's what I missed - the firing twice as often bit.

    Yeah, I see that Porsche have come up with a racer with a flywheel powering a couple 'letric motors - from memory an extra 200hp for 5 - 10secs after hard braking. Wait, here's a linkee:

    using the flywheel like that sounds like a bloody good idea. There another car that does similar (may be the civic hybrid) and an added benefit is that it acts as the starter motor as well.

    Ok just got my hands on a set of L brackets for my bike (which is good as I found out that they're out of stock at Ventura!) and think I've figured out how they're attached(came with no instructions). Only problem is that I will need two threaded bolts that are an extra 18mm longer. Anyone know a place in Palmy or in area that can help with this?

    I use milson metals, tremain ave near the hospital. They won't have the proper MC flange bolts, but cap screws are just as good (higher tensile strength too) just get zinc plated ones so they don't rust.

    The length has to be right as the bolt on the bike is secured at the end with a cap and not a nut. Sorry but what is a MC flange bolt?

    hmmm, could be difficult if it's not a standard length (multiples of 5mm generally), motorcycle flange bolt, normal bolts don't have the round bit between the hex head, and bolt shaft, looks fugly if you use a normal instead of flange on a bike.

    In hindsight I proberly should've taken a couple of pics to show where and how the bolt goes on bike but the light bulb in garage decided to crap out on me.

    Anyhow I should find out if these guys ca help when I take one of the original bolts in. Still at the end of the day I got a good bargin paying only $13 as opposed $150 new which apparantly is now out of stock.

    So, I had a peek at the pilot screws, went to adjust them and number three screw is....screwed.


    On the plus side I had another go at the fork legs with more AutoSol and some 1200 grit sand paper, taaaasty.

    Fuck, I knew there was something really wrong! All four are pointing the same way too, what the fuck is that all about? No wonder it sounds like a sewing machine.
