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 ! ........and 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 ! Trinidad & Tobago. West Indies.

[@piearm1271]

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.

[@superturboawesome1]

That bike sounds amazing!!! I want one!

[@S42069]

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

[@korzbro35]

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 ;)

[@alc7505]

Thanks mate! Your right, very few ppl think its anything from a normal motorcycle. But when they're cluey enough to work it out, they want to spend all day checking it out!

[@karlalton3170]

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

[@marting.4505]

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.

[@roblandis]

Awesome build

[@CedarAshCanvas]

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

[@garyhooper1820]

Awesome project !

[@dank5432]

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!

[@jric5097]

Thanks for the book recommendation! Cheers 👍

[@johnanderson6566]

Diesel motorcycles are rare cool bike

[@onkelt2624]

It looks perfect.

[@garykeenan3724]

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

[@AutodidactEngineer]

Sounds better than most harleys lol

[@korzbro35]

Not really :) but it does have very interesting and "raw" rumble.

[@muhammadabrooramrullah996]

If you mean harley EV... then yes

[@thehaze1972]

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! 👍

[@simonbertioli4696]

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

[@endruewbatista2433]

10:18 thank me later

[@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?

[@ItsDaJax]

Hell yeah.

[@johnparrish9215]

Nice job

[@easy_._rider]

Чувак, ты крут! Моё почтение!

[@richardcormier4561]

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

[@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.

[@alc7505]

Thanks for your comment! Ive got it geared to do a maximum of around 110km/hr so there isnt much room to add more teeth on the back sprocket without making it a town bike at this stage

[@АлексейВальков-ю9г]

Wery good! Whot is price?

[@hankcuccina5260]

Very clever.

[@chevy6794]

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

[@dannewburry2919]

Great job, wondering a year on how you finding it

[@alc7505]

She doesnt get alot of use, but when It comes out it is alot of fun. No issues other than cvt shifting issues, mostly at low speed. Upgrades coming soon

[@RegiPavan]

😎😎😎😎

[@davyr4302]

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 !

[@alc7505]

Definitely took alot of commitment to finish this project, thats for sure! Used a cvt because it was easy, cheap, plus at the time it seemed like it would work well with the low revving diesel. However I do experience belt slip alot at high speed and have decided to attempt to remove the cvt and fit an enfield 4 speed gearbox to get rid of the power loss. Will be interesting to see if i can fit it in there! The engine is mounted on bushes directly to the frame only and the factory suspension is 100% original so there is no rubber mounting to influence the rear swingarm. Everything runs really smoothly regardless of speed. Top speed is only about 120km/h. Sits on 100km/h fairly well but im hoping with the correct final ratios in the new gearbox and no belt to slip that it will get the power to the ground more efficiently and sit on the highway easier as well. The bike is almost exactly standard xvs1100 weight, cant remember off the top of my head but between 250-260kg I think.

[@jontwofeathers]

I was going to say put some vents in it

[@Conradchristopherson]

Your clutch needs more air.

[@SpencerHHO]

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

[@SpencerHHO]

Nvm, saw the qld plate but would still like to hear about your experience engineering it.

[@alc7505]

Pretty easy. So long as it is built well, similar weight to original, less HP and emissions of the new engine comply with regulations of the year build of bike used. This build would not be possible on a more modern motorcycle due to nore strict emissions regulations. Also if you cut/ extend the frame it pushes costs through the roof as you have to get frame twist tests done once modified as well as brake and suspension testing.

[@hugomunoz956]

DOPE

[@kevinhkirkpatrick6155]

Turbo?

[@alc7505]

Chitty chitty Bang Bang!!!

[@peterklein4349]

a shame there was noone to assist you , with this video. It's now only technical explanation, less to see or hear

[@sukhjinderpk77899]

How many price

[@Artus6114]

d'ont existe for buy or....?
