377cc Rotax Bombarider Ski Doo snowmobile powered Twister Hammer Head buggy custom

[Dave72mph]

Kinda sluggish

[mikeyr260]

yeah the trottle helped haaha

[MrScotty2469]

ctrl w to get rid of adds

[jewsychicken]

thats slow

[nitrokid99]

how is the secondary clutch moving and the buggy staying still

[nexaura]

it never had a 6.5hp briggs engine @ asssface2000, it came with a 150cc GY6 chinese engine- i am building the same 4 wheeler right now with a Yamaha 538cc Electric start snowmobile engine, that should do it , lol

[asssface2000]

that thing was faster when it had a 6.5 hp briggs and stratton in it!

[t11d9t12]

That's fucking sick man! AWESOME job!

[matt90679]

nice NOS energy drinks

[tacticalkid2468]

u said it was spitting out oil and it wasnt running right check the crank seal mine whent out and it spit oil out of it a lil and it wont run right if u dont have it

[NRKaudio]

ur a bitch ....rotfl

[origionaldz]

@NRKaudio Why am I a bitch?

[NRKaudio]

@origionaldz the dude behind you said it and i pointed it out...i was funny..love the NOS cant go wrong lol

[FrenchValleyAirport]

@origionaldz the guy in the video said that... hes just repeating him

[bRitttttx33]

@NRKaudio y is he a bitch?im curious

[NRKaudio]

@bRitttttx33 idk thats wat he said in the vid



[richardarichter123]

how fast does it go top speed going to build snow kart

deciding on an engine

[cruesader12]

tighten throtle smaller exause end for lound and ubnoxios fun and better fennders

[MrAaronroy]

i have a rotax 377 plane engine that has been siting for about 5 or so years what would we most likely need to do to get it running.

[03arcticcat]

looks like the head will hit the frame when the rear suspension compresses?

[oddyextreme]

clutching is way off 

[graci67]

snowmobile engines are a pan in the ass but are funn

[Chumbbo]

do you have overheating problems

[origionaldz]

@Chumbbo Nope its fan cooled

[Chumbbo]

@origionaldz yeah i ment in the summer, for my go kart im putting some sort of tube from the fan to the top of the cart to force air in

[paratrev]

@origionaldz yeah but even then, it will blow up from overheating because its meants for winter. i dont care if u rejeted the carb, eventually it will fuck up a rig er two

[origionaldz]

@paratrev Been over a year, still running fine. The only thing this gearing does is put the engine into power band earlier, which means the engine isn't struggling as hard to move the weight.

[fastass73]

@paratrev this dude has no clue what he's talkin about, we use snowmobile engines all year for ultralights and yes they are air cooled with no issue as long as there jetted right

[TanSnipes]

needs a paint job, and ittl be sweet.

[462ccLiquid]

as a proud owner of a 377 that thing should have ALOT more power! but unlike "calholli" said, a CVT system isn't meant to feel like there are gears changing unless there is a flaw in the clutching system. I have never experienced that even with 4 wheelers (yes some have a CVT), I've driven old sleds that have been properly maintained as well as some right off the show room floor and still never experienced that. And yes as everyone said, fool around with different prockets.

[origionaldz]

@462ccLiquid It has a lot of power and it still does have some speed. This video in the backyard doesn't show it stretching its legs. If we wanted more speed we would play with the gearing. But it goes through the mud and up hills so the power/speed is a tradeoff.

[woah4]

Lovin the nos bottles Lol good job guys 5 stars

[origionaldz]

@woah4 LOL thanks. The NOS bottles are meant to be a joke, some people that don't know a lot about it thought they were real lol. 

[calholli]

all you need to do is put a smaller sprocket on your axle.. or a bigger one on the other end of the chain.. OR BOTH.. whatever is easier..... . your almost there.... that thing could really fly with different sprockets...... the clutch system on the engine will act like it is shifting gears as you go faster... . you want your chain sprockets to be about the same size as each other!! . try it, it will make all the difference in the world... I promise you

[technigogo]

I bet the neighbors "loooove" you.

[origionaldz]

@technigogo Eh, we just built it I wasn't just gonna look at it in the yard lol.

[Skid00everest340]

sounds even like a snowmobile. i got a ski doo everest 340 snowmobile

[Softairguy]

a rotax 377 hasn't 377cc but 368

[origionaldz]

good job

[Cringle84]

Good but needs better gearing, or else put a motorcycle engine in, takes away all the complexity of worrying about a gearbox. a 2 stroke 250-400cc KTM YAMAHA or whatever engine... mmmm.... doughnuts.

[JimJaySon]

nice , but needs better gearing.

[420witchdoctor]

Cool flywheel.

[kinellfire]

that is a great project. how does it compare to the original in terms of speed and handling?

[origionaldz]

Handling is still the same as the original. We did put shocks off of a raptor 660r on the rear to help cushion it a bit. But the power ohhhh man it takes hills so much better and takes off instantly.

[OffRoadKartsRule]

ha I like the buggy Im pretty sure this was the kart i got my engine out of. I had my go kart at kidnmekarts and i blew my engine and some guy didnt pay for his so they kept his kart so they game him my engine and i took his. After the engine was out Mr. Tom gave the kart away.

[elced22]

I would not have used a fan cooled engine because it will run too hot and won't perform as well as in winter cold temperatures.

[origionaldz]

Well, being that it is fan cooled means that it WILL be cooler running. You should probably tell homelite or sthil or echo to stop making fan cooled two strokes because they may run too hot in the summer too?

[Hawkster0001]

@origionaldz well yeah it wil stil perform fine, but what i think hes saying is that you lose some power. but its hardly noticeble considering its more efficent with ptting the power to the wheels, so its an even tradeoff

[Garrettfootball]

wow, 15mph

[origionaldz]

Wow, looks like you don't ride at all?

[bigorangetrucker]

i used to have a 89 Safari with the 377. cooked a piston in it doing donuts on the ice, put in 1 new piston and rings. was a great sled until the throttle cable got stuck and I ended up rolling it on the ice. broke the hood all to shit.

sold it for $300.

RIP safari

[origionaldz]

Had a similar experience with this safari, was rolled so many times the body and all just broke down but the engine ran great. This engine has never been opened up, still runs great.

[xmxcubedxmx]

good job! that bomber box is originally geared to run a snowmobile track... i would pick up a odyssey 250 gearbox and toss that in there :) that way your power wont go to waste... imagine riding a ten speed in high gear.. you are peddling really really fast with no resistance.. but the bike doesnt move.. better gearing and the motor will do less work.. and you will have more power to the wheels! :)

[paskracing77]

if you don't get that geared better your going to end up blowing the engine you almost have no load on the engine, i,ve built a couple carts with sled engine and had them so they will do 100km your not even getting 50 it seems

[origionaldz]

Trust me, the way it is now it has plenty of power and speed. It walks right by other buggies. Power band doesn't really kick in till about 5-6000 rpms anyway.

[mothombo]

your probly gonna have to get a bigger sprocket welded to obtain the wanted speed and take off.... if not you wont be really useing your powerband very well and it will just rev out

[yannobos]

sled engines are ment to rev out, they have a centrifical progressive clutch so that the higher rpm, the more speed, its like the gearing on a mountain bike when you get going faster you shift to taller gear thats what the clutch is for
