My quad project...with pics, sorry no turbo :p *lil update*
 

Well guys this evening I started on my quad project. I have a 350 warrior but was unhappy with it. So i traded my father for his honda 250x.

Anyways I'm stuffin my dad's dirt bike engine in it...he used the bike for ice racing. Its a 360 bored 110 over with a weisco piston, milled head, port & polished, stronger rod, larger carb etc.... Anyways I'm hoping it will be a nice sand dune monster when I'm done.

Here are the pics

1987 Honda 250X frame

This is the 360 Yamaha motor.... I cut the frame on the bike a few years ago to save it. I was going to put it on a gokart originally

Well the engine is in the frame. The very rear bottom bolt lined up perfectly but the other mounts I will have to alter. I had to remove the carb, a spark plug and the chain guard just to fit it in. Its a tight squeeze, when I'm done just to change the plugs I'll have to remove the gas take. I suppose I'll make it hinge with a wing nut on one end for an easy lift or something....

Ok, here's the problem. The engines sprocket sets in about an inch and a half from where it needs to. I'm either going to have to move the mounts over or extend the sprockets shaft somehow. I beleive I'll try to extend the shaft first since the engine already mounts nicely where it is....

I was really expecting it to fit as easily as it did. The task should be easier then expected. When its finished I will swear that its a 250X... stock ;)

I know its probalby common to most but I'm enjoying doing this. My dad is excited to see his old race bike engine fired up again...and to up my life insurance along with it.

Geez 32 views and no replies.... I suppose this is one of my shitty posts. Assholes :p

I figured at leats Dr Boost would appreciate this lol

I'm just pissed I don't have an ATV yet, in the next couple years I'll get one, after I get my truck though...

Re:My quad project...with pics, sorry no turbo :p
 

Haha, I just saw this post. I dig it. I want to do some hybrid action to something, I just don't know what yet. ???

If you extend that front sprocket out too far it might compromise the integrity of the shaft. I'm sure it will at least blow the seal eventualy. It might be a bitch, but you're better off moving the motor over a bit. :-\

You're going to clean that motor up a bit before you fire it up right? It looks like a small forest inside the intake. :o

Also, you might want to shave the "Yamaha" off the side of it. ;)

Yeah I was thinking the same thing about the shaft...I thought it may even bend. I can move the sprocket on the spline out about 3/4 of an inch with a spacer on the back of it. Then I'll try to move the rear sprocket in a lil bit and see if i cant "compromise" something. If that doesnt work I'll start making all new brackets. I was just so happy that it fit like it did that I wish not to change it.

Yes of course I'm going to clean the engine. Once I get it fit up correctly I'll remove it and clean it all up. I'm not shaving the yamaha anyways though, I'm more of a yamaha guy then a honda boy anwyays.

Re:My quad project...with pics, sorry no turbo :p
 

You should send some parts off that my way to powdercoat, it'd look sick... HMT xmas special, just cuz I want to see that thing look as sick as it should.... and now I've got a month of school

Re:My quad project...with pics, sorry no turbo :p
 

i am currently searching for a quad frame to insert my heavily modded kx500 motor into, im looking forward to building something else insane

Re:My quad project...with pics, sorry no turbo :p
 

that reminds me heh heh heh my and my friends are putting a 650cc motor cycle motor on a go-kart lol it is going to haul ass if we ever get it done, also we have to make sure we dont kill ourselves cause we aremaking a custom frame and everything. when it is done though it will be cool.

Re:My quad project...with pics, sorry no turbo :p
 

Well Dr. Boost you were right, I decided just to move the engine and make all new mounts. Here's an update because well I'm bored :p

looking good man, keep up the effort and it'll be turbo in no time...

Re:My quad project...with pics, sorry no turbo :p *lil update*
 

Damn, you're a motivated mo fo. I didn't expect you to just go do it. Nice work. By the looks of it you'll have that thing running in no time. What other obsticles are in the way?

I can be motivated at times. I spent the weekend with my girlfriend so I didn't accomplish anything more yet. I didn't move it just because you said so. I looked at my options, it was really the only one so I figured I just better do it.

I still have some things to overcome though. I still need to make a couple more brackets which wont be hard, no more welding them anyways. The Hardest problem will be the kick starter. On a dirt bike you kick backwards, on a quad all the kickstarts are rigged to kick forward. I'm going to have to move the rod forward and bend it out so I can get a full kick without hitting the frame or plastic fender.

Actually the hardest problem will be the exhaust. I have to make the stock expansion chamber work on there somehow, I'll be cutting and welding it in where i can. It'll get done.

I have some other work to do but nothing much. I have to get the chain setup which wont be hard. I need to make a kill switch, run all of my cables (i'm converting to a twist throttle which I took off the bike). Lets see what else... Thats really about it, besides running some new fuel lines and such.

I broke this little plastic piece on the motor that had a rubber line attacted to it. I need to find a new one of those :( Wish I had not broken that but I did it while I was cleanin the darn thing.

Re:My quad project...with pics, sorry no turbo :p *lil update*
 

I know nothing about ATV's, but it looks very nice ;D

Re:My quad project...with pics, sorry no turbo :p *lil update*
 

Lol, I know you didn't move it just because I mentioned it. :P

Looks good so far. That kick starter is going to be any ugly mo fo. :-X The exhaust might be tricky. It should tuck pretty close to the frame thoguh, right? Is it hitting ---- or will it hit ---- if you tried to mount it stock?

Keep up the good work. :)

Yeah I know the starter wont be pretty. I'll probalby at lesat paint it or make it look better somehow. I'm more about effectiveness rather than how it looks.

When I'm done the exhaust will hang close to the frame. Currently the stock on has the bends in it for the motorcycle frame, which obviously dont match what I need. If I mounted it stock it would interfere with the plastic pieces...I'll try to take some pics later to show it.

I'm really excited to get this thing running.... its definitely going to be faster than it used to be by far.

Re:My quad project...with pics, sorry no turbo :p *lil update*
 

Hey do you have this thing running yet? I use to own a 250X, 300Ex, and a Warrior (not all at the sametime) Haven't had a quad for awhile now though. But I must saw the most amazing one I ever rode was the Banshee, it was insane and I loved it, don't think I could ever go back to another four stroke after riding that. Still hope to pick a Banshee may be after the car is paid off.

Re:My quad project...with pics, sorry no turbo :p *lil update*
 

Wow,

talk about back from the dead... Anyways no its not done yet, I honestly havent done much work.

As you can see the coil on top of the jug in one of th pics is pretty ragged. I'm having a problem gettin spark. I had it then i soldered the wire back together and then i lost it..... anyways that kinda sucks.

Once I have spark though it should be running, I'm hoping to work on it a lil this weekend between other projects. When I'm done and riding it in the spring I'll have some nice sand dune pics.

I'm hoping for it to be able to eat banshee's...its over 400cc and fairly built.
