Yamaha V-twin diesel bike

Here we have my Yamaha v star 1100 which has been converted to an 875cc v twin diesel engine with variable belt drive/ cvt.
Bike frame is a 1998 Yamaha v star 1100.
Engine: 875cc twin cylinder yaikin, punsun, winsun stationary diesel engine.
Drive system: Comet 94c ribbed duster clutch with 90d driven unit. 25.4mm keyed jackshaft.
Fuel efficiency: approx between 3.0L and 3.3 litres per 100km. These are testing figures with alot of heavy acceleration.

Nice build !
It looks like factory !
i have a pair of Fiamm horns like yours !
Maybe you can install a mini 12V fan sold in electronic shops to keep the CVT belt cool.
Great, just great !

That’s a good conversion, looks factory, well done for persevering and finishing this so well. Cvt is a great idea but looks like the torque is overcoming the belt, hope you can get a decent gearbox as it’s going to unleash the potential.

That bike sounds amazing!!! I want one!

Man, what a clean conversion. Untrained eye (I mean non-biker) might not even suspect that this is far from typical motorbike :)
Holy shiet. Even some not so seasoned bikers might not notice two unusual things (diesel & CVT). Awesome.
And it sounds amazing! Very industrial, almost brutal tone. Love it.
Not to mention the consumption is probably laughable ;)

I have a very similar project... a 912cc diesel on a Road Star 1600cc frame

[karlalton]

Very nice job dude, looks like a factory bike attention to detail Awesome 😁😁😁🤘🤘🤘🤘🤘

Nice bike. I've been thinking about doing something similar, I've got a 1992 Kawasaki VN-15 rolling chassis at home, it's just missing an engine.

Well you basically solved the belt issue right there, cut some vents. 👍. CVT:s are really inefficient so they create lots of heat but they work really well. Really nice build! Big thumbs up! 👍

[garykeenan]

Looks really good, I like it a lot; probably rides just as good!!! 👍✌️

Assuming you have you read Paul Carters book "is that thing diesel"? Well done on your bike it's an engineering feat by the looks of it!

Some 2 stroke snowmobile CVT clutches can handle 150+ hp, but might be hard to come by in Australia, I'm guessing. Good luck.

[simonbertioli]

Nice, and a well thought out build...
Impressive, but yet cool..😅

[formerice]

My Arctic Cat diesel has a blower on the CVT. They use a Rule Bilge blower for a boat. Maybe you could adapt one to keep it cool?

[dannewburry]

Great job, wondering a year on how you finding it

[chevy]

What about baker transmission or something separate like on a Harley?

[richardcormier]

That cover you wanted to chrome why not modify a front disc brake chrome cover off a Honda gold wing it's slotted with a vent scoop for cooling

[davyr]

Amazing !!! I have been dreaming of such a build since forever ! Scared to take up the project, worried I wont be able to complete it. Can you please answer some of my questions - 1. Why no transmission ? 2. My research result is that engine needs to mount hard on to frame, no soft bushings (Harley death wobble) - did you consider that? 3. Whats the top speed ? 4. How much does the motorcycle weigh ? Thanks for the video !

[SpencerHHO]

What state are you in and what was the engineering process like?

[PeckhamHall]

Nice job. Maybe changing the gear ratios could help with the belt slip. More teeth on the back sprocket or something. Also, make sure the swing arm doesn't tension the chain.

[jontwofeathers]

I was going to say put some vents in it
