Everest 900 - 900cc 4cyl RV Teaser / First startup (flywheel problems) 

Lol

eamh2002 day 200 about 4,486,397 pull and it started

Ha

Ain't that the f*+-* truth lol

Hi! Once in a week yes i agree...but try to drive a 2 stroke 50cc everyday and you will change your mind about the smell...try long drive and you will change your mind about the sound! I have now a 4 stroke scooter with a big bore and a few change and I go faster than any motorcycle or any thing with 2 wheels in town and between here in France because it is smaller and speed limit is 50 km/h so about 32 mph and there's radar everywhere so agility torque and a good eye are what makes the difference not horsepower!

logan leborgne that I totally agree with but where a track is concerned, give me my CR500 or KX500 over a 4 stroke any day

@@shaunpc2512 🤩👍🏻👍🏿👍🏾👍🏽👍🏼👏🤝🖖🏼...a totally different world...I agree! Now that I think of it 2 stroke vs 4 stroke is a consideration of the past now!!! Have you tried any electric motorcycle or scooter? I tried a few and the last one I tried was a "50cc" whose speed is 50kmh or 32 mph but with an internet app it go 100kmh so 63 mph(there is an USB port to charge a phone but if you do a manipulation it double the speed but it work only once you have to do it every time you start the scooter so in case the police arrest you they can't proove it!) I try an e-bike with the same kind of modification but build in no app needed...wow it was fast and very nervous...it can burn out...and it wasn't that big...maybe kind of 400cc...the day they will built something who equal a 1000cc it will be crazy! There is e-bike who have the same acceleration than your CR or KX(I use to have a kx 80 an YZ 125 then 250! Long time ago)now but maybe not the same sound 😉 and you will need a lots of battery!

wond if there is a way to form the rotary valve or shape the intake side of the "block" to drive( or create a negative pressure) the fuel mixture into the hole.. even better, a standoff injector just in front of the rotary valve (Renault did this in F1, when their wide angle block had resonance problems in the intake , as a result of high vibration, and electronic noise bugging the injector sequence.. perhaps combine a carb for low end throttle, and a standoff injector comes in only on the pipe..if one could get around the oiling problem..may clog the injector.. would make for a wacky fuel deliver system .... Never understood positives a rotary valve give's you.. what's the reason they were chosen in liue of reeds.. ?

Stratification people!

Franco Barone eklkkkk rekkkk rekkk rekkkkkkkkkk 😂😂

It was a lot easier to start when the ignition problems were solved ;) but yeah an electric starter probably wouldn't hurt. He's working on it.

@steelmesh heck yeah they do, fuel injection is much more efficient and an overall way better system

It is! I'm a bit jealous really now that's it's finally nearing completion... But not feeling too bad about not having to build 4 pipes for it ;)

They both had aches the day after ;) my excuse was I had to hold the camera :)

Very cool! This one is made from 2 454s.

@Simon Roscoe flywheel was at the wrong point on the crank and was firing too early which is why it only ran at high rpms, that's my guess

Problem is it wasn't 100% functional :) the flywheel taper was damaged a little bit and it was moving every pull (recoil starter drives the flywheel), screwing up the timing. We adjusted timing several times but one pull later it had probably moved again. It starts first or 2nd pull now that that's fixed :)

This particular one has 180 degree timing so it kind of sounds like a 4 cylinder boxer. Cylinders 1 and 3, and 2 and 4 fire at the same time.

Yeah the TZ750 had a 180 crank with 1 + 4 and 2 + 3 firing at 180 of each other. Sounds nice.

Those were the days!

Yeah I gave up on dirt bike riding when most manufacturers went to shitty thumpers. Long live 2 strokes! Glad to see some manufacturers are bringing them back. 4 strokes just aren't the same, & in my opinion are only good for road/trail & long distance cruising. For tight, technical, jumping & pretty much any hard riding 2 strokes are king. Plus their power delivery is way more fun.

Dankje!

He made them himself, I think the pipes were about half the work put into the whole machine. I guess a warm butt is an added benefit but there's a hole in the chassis underneath the radiator there so it gets cooled by snow while riding.

That is funny mate

Or he could of just got a power drill and started it on the crank pulley. Also heating up the engine would of really helped.

@@ACplanet no you invented a spinny thing.

Ye mate

It turned out to be a problem with the flywheel. It usually starts on first or second pull now (with choke).

Yeah, too bad I had to take care of the filming so I couldn't help with the pulling, real shame ;)

They are 2 2-cylinder engines. The 4 cylinder crank has an extra "center piece" out of a 3rd crank between cylinder 2 and 3.

n00bkill they need to just have an option for a nut on the flywheel for an external starter with a socket like a Briggs 3hp setup with some handles... Still can’t get over the fact they would make something so beautiful and put it on a fking snow mobile... if he would have made a V4 and throw it on like a 99 TL-1000 frame.... He probably could sell it for $30-$40k +

+Alexander Jäderblom He started almost 2 years ago ago I think, can't remember exactly when. It was first supposed to be done last winter, then last summer, but now it's finally getting close :)

The flywheel taper was a bit damaged so timing kept moving on every pull, we adjusted it a bunch of times while trying to get it started because we thought we probably just didn't set it up correctly. It starts on first or second pull every time now after fixing that :)

@@Hollaendaren that's fantastic 😀 I have been enjoying watching you builds they are very impressive 👍 Cheers Mark

People hand start worse than this :) but a starter motor probably wouldn't have helped this day, it was a timing problem. Now after fixing that it starts in 2 pulls usually, a couple more if he just rejetted and the float bowls are empty. He hasn't dynoed it yet but hopefully later this summer. I think he would be disappointed if it has less than 200 :)
