Looking for Dirt bike or ATV engine!

[Bamm-o]

Hey Giants. I am looking for a Dirt Bike or ATV engine around 150cc-300cc size. I am hoping to find one that runs but if it needs little work I am still interested. I am also interested in other engines like a 250cc snowmobile engine etc etc..

I am building a Drift Go Kart and I need a good engine with good power to fry the tires for drifting. an I.C. engine with a centrifugal clutch won't cut it unless there is a centrifugal clutch out there I don't know about that grabs well?


lemme know if any of you have any and wouldl ike to sell it.

I have been racing Karts for many years, with several National Championships to my credit. Maybe I can help. Here is what I ride for fun now. My wife has an 80cc modified Kawasaki KX motor with 6" wide x 5" rim tires. It won't cut it, though it will be fast(90mph). The most common class with moto engines are the 125cc jobs. I run 8" wide x 6" rim and they will only slide in 1st and part of 2nd. I have run 5" wide tires on it, and it will most certainly roast 1st, 2nd, and some of 3rd. The 250 Hondas we have will roast all 3, but nothing in 4,5,6 gears with 8" wide tires. The 500cc Hondas I have run on Karts are such a pain. Hard to start due to compression and just raw size. They break more stuff than it is worth.

Can I say this much? Having driven several D1 competition cars, and logging a ton of drifting hours in various cars, it is going to kill a 2 stroke. You will have to spin it so hard to keep them spinning, you will eat con rod and main bearings like they are candy! Wet tracks and rain in karts proves this.... you just can't brutalize a 125cc moto motor. They are 12,500 rpm peak motors, not sustained. A 4 stroke would be a great motor for this, but again, this stuff is so hard on everything. A real D1 car will eat a motor in 8 runs, or, 500 miles of track use at the same rpms, it's just not the sustained rpms of drifting. I don't want to discourage your efforts, just know that you WILL spend $2200+ on an old kart and motor and constantly fix major stuff. Axle's, motors, clutches, etc.

I have a '94YamahaFXR1000. Crank has been lightened and heads are polished. I have dynosheets showing 130HP on the rear wheel. It's been parked since 2002, when I bought an '02R1, so carbs. need serious cleaning. You can have it for $1,500.00 if you want.

thanks for the info Gremlin! wow I never knew these things. hmm... well I was talking about a four stroke dirt bike or ATV engine but ok Two strokes are out of the picture.

BUT I am designing my own go kart chassis and probably just gonna buy some parts from GoKartgalaxy.com (Axle, bearings, etc) I just drove a Race Kart yesterday and got the feel for a kart that is super WIDE and short. it was to twitchy....

I'm going off of Spidercarts.com 's Recluse. I didn't order the plans but I am taking the chassis design and modding it a lil bit and stretching it. I was planning on using 6" rims with a 4" width with slicks.


My main goal is to make a go kart that can drift. I watched a movie from like the 60's called Bikini Beach, and a guy was driving a vintage go kart and he was drifting! (at that time I bet they only called it power sliding) but I was like YES it can be real! (drifting a go kart) I'v noticed from vintage racing karts to now adays karts that the vintage karts were narrower and longer. now aday race karts are short and wide. plus with these super WIDE tires it would make it impossible to drift.

all and all I just am going to try every way to make a Go Kart drift. if plan A is to hard to drift I am going to plan B and going to figure out how to put some ABS tubing over the tires to make it slide just like a RC drifter.

a little to big lol thanks anyway.

My dad has two drag bikes. one with a Kawasaki 1300? or some thing big in that range and the other a 750. my first idea was using that but trying to keep it a Go Kart lol

Oh yeah, 3" wide Carlisle tires, twin US 820's and 60% nitromethane... they drift. The olden days of Karts were more fun. They made them with too much grip these days. With a proper data system we spike 5 g's no problem, and sustain 4.2 all day long...

bringing oldies back! yeah. when I was racing that Race Kart yesterday if I was gonna ride alone for a good 30 minutes it would have gotten boring but then the clutch broke. but I can see racing against other people on a track... now that may be fun! Moroso Motor Sports park 5 mins from my house they just built a new Go Kart track. every time I go out there its pretty cool to watch em' race. be even cooler if they were drifitng around them courners...

who knows.... this may start a new level for Drifting...

Any one know how the Lifan engines are? probably the same engine as my Pantara dirt bike I had. it was a peace of junk but I also ran it hard for $350 thats not bad but if it will break like my Pantara engine did. not good.

If I were to build a drift kart( no way), I would use a Honda CR 250.... lots of torque, on't have to rev the snot out of it, and you can get parts for them easily.

Fun stuff......... When I was still SCCA Autocrossing, my nickname on the discussion boards was/is Oppositelocksmith. I'm sure GremlinX gets the meaning of it...... LOL

Buahhaha, yeah... I know what thats all about... I imagine that 1100 cc nasty cycle motor on there is about a poor handlin' machine!
