HI Tristan Good choice of motor I’ve converted seven Honda superdreams using the z482 engine ,four using the Comet / Axiam CVT . You’re getting lots of good pointers and I'll add my money’s worth ! The CVTs I built I opted for gearing them for approx 65mph at max rpm . I used a toothed pulley rear d...

I sure you've all ready spotted this one but if you haven't it's Ruggerini 2 cylinder in a generator for spares listing no 252393138039 , Could be a cheap engine as it has issues https://www.ebay.co.uk/itm/252393138039 .

Cheers Tim

Hi there
Sorry for the slow responce !
The Driven pulley is 200mm Dia the Drive pulley is 192mm Dia and the belt circumference is approx 920mm ,.I also have a homemade jack shaft that fits the Driven pulley which takes standard flange or plummer type bearing blocks.

Cheers Tim

Hi
Any one riding up from the South West to the BK ? Shout out as it would be good to team up for the ride!
Cheers Tim ( near Yeovil)

Hi Your both right ! I was concerned with possible issues of pulsing using small engines with turbos . So you quite right about using the intercooler to increase the plenum chamber volume between the turbo and the inlet valves. In deed still at lower rpm the gauge needle tends to fluctuate wildly . ...

image.jpg image.jpg I spent some time playing with the design for the cover , 3mm expanded foam was strong and impact resistant but I couldn't get it to form any reasonable definition so I opted for thinner high impact polystyrene with a metal bracing frame underneath. The 3 cylinder is a definite ...

I have the same fender clearance issue on my bike. I would imagine your Kubota is heavier than the original Honda lump. I built spacers out of pipe and stuck them in the fork tubes under the caps to preload the front suspension springs to compensate for the extra weight. It worked. My spacers are a...

Possibly it's slipping on the engine side when you put more power on it. The way it behaved when standing still and opening the throttle it didn't sound like it was putting on much load. Any change in power into the c.v.t. should result in a feel of power on the road. If that's not synchronised you...

Heavier fork springs and a less "boxy" mudguard?? The only other option might be to rework your exhaust in a similar design to your inlet manifold which would be a shame after the work you put in. With your CVT I would go back to standard to see if that helps. Possibly your changes have m...

So the weather was nasty but the excitement won the day and the MK 5 went for a very short test yesterday ! I love the sound and feel of the 3 cylinder engine but the cvt system isn't changing up correctly and the radiator is leaking for a tapping point . The front mudguard hits the exhaust when bra...

meez and ol Curtis been going round and round last two days via the net about side load on the crank bearing of the Kubota diesels. Basically there is NO end crank bearing. Just a bush and an oil seal. Thus for longevity in reality with these Kubota engines we should all be using a roller bearing s...

In addition I didn't want the shape of the belt run ie crank , alternator and pump triangle to dominate the looks of the engine . I do like the clean and uncluttered look you get on that end of your engine Tim. It's unfortunate if you have to bring back the water pump. My solution was to utilize 2 ...

Hi there The thinking being the bowl shaped pulley they use effectively adds around 80mm to the width of the engine at a point that stcks out visually . In addition I didn't want the shape of the belt run ie crank , alternator and pump triangle to dominate the looks of the engine . I have added a pu...

Hi Alex I am a sado fair weather biker so subject to weather I aim to bring the turbo MK 4 and the 3 cylinder mk5 bikes and if rebuilt in time the original mk3 Kubota engine bike to the big knock . I did rebuild the top end and assessed the bores as being in really good condition , maybe the rings a...

Are you certain you need that silencer Tim? Sounds awfully nice straight off the header pipe. How about a video or 2 of you accelerating through some turns without the silencer? That my friend, would be pure auditory porn. I have a straight pipe on mine. It sounds really nice, but its very loud, se...

Hi Yes I agree with your reasoning. The cvt in an overrun situation will try hold the engine at a constant rpm regardless of speed. If you encounter a very very steep hill it increase the speed of the bike but keep the engine rpm constant . On a slight hill the effect of the good engine braking will...

So the maiden voyage of the turbo mk4 was interesting , the handling was appalling but I found front tyre pressure at 10 psi and the top yoke nuts were loose. The turbo makes a wonderful wheezing noise when it starts to spool up but I didn't push it very hard as there were lots of hot smells and sm...
