Re: Adding Turbo

I wonder if you could add a mixture lever, and nudge it back when you're not doing high speed. Mine just slows down when I get to the end of a tank and the fuel line fills up with bubbles, so cutting fuel might be hoped to do the same - rather than run lean and melt your pistons...

Round our way the delightful kids often burn stolen bikes. I would like to have been there if this lot tried taking the cap off and throwing a match (or 6) in :) Glad you got it back.

That's the only kind of CAD I'm into - Cornflakes-box Aided Design :)

I'm enjoying your thread. I'm jealous, really - I think you're exploring a really interesting balance of power, availability and cheapness of ingredients (and weight!). I'm keen to see how it comes out.

Re: Could this be the start if Sluggy II?

Turn the tapered part down to the largest cylinder you can get away with and then press-fit a plain shaft over it, to size? Weld it though a hole, or pin it, to withstand the mighty torque... :) At least it would all stay true.

Re: Finally I can start! Aixam+CVT based build

I don't think my mate's Guzzi V50 / Z482 does more that 60mph. That's through the guzzi gearbox / final (shaft) drive - he's used the best set of ratios he can find, but maybe you'll have more flexibility. It's not the fastest bike, but good on fuel, and very reliable. Engine spares are easy to find...

Re: Adding Turbo

I'm using a Daihatsu Charade 993 turbo-diesel. It's built into the exhaust manifold and it's really close to the head - I guess where the exhaust is most energetic. I think that's where you need to be, which means making a new manifold / downpipe and arranging clearance for your front mudguard and r...

Re: Frozen coolant

Bad luck!

I don't understand why if there was only a bit of water in it, ice did not expand into the air spaces in the water jacket. Seems odd that enough pressure developed to blow a core plug. When you ran it - did the water jacket pressurise - is that liner crack an issue yet?

Re: Turbo's on singles - effective or not?

I don't know the correct terminology, but I guess it depends on the input impedance (ratio of pressure divided by volume flow) looking into the cylinder when the inlet valve opens. If the input impedance is low (large flow) then all the pressure built up by the turbo / supercharger will collapse wit...

Re: yanclone (DEK) 418cc not running to well

I use a see-through plastic 2-port fuel filter, and see-through plastic tubing. If you try that, you can see whether there are any bubbles floating around. From my experience (Daihatsu 3 cyl) you might need a lot of bubbles to notice it running odd, and it sets in first at larger throttle settings, ...

Wow, that's a lot of work gone into that.

I've only killed one puck in about 2000 miles, and that was in re...

Enjoying catching up on your thread now I'm back from holidays. Ural bevel drive cover gaskets play a similar role in regulating backlash - but on those, you can shim the pinion in an out as well.
