2002 blaster with a yzf 600 motor?

[mrtwelvevolts]

I got an 02 blaster for $200 and the tranny is locked with a cracked case. I have the option to buy a wrecked 07 yzf 600 with 91 miles on it for $500 good motor and the parts to make it run are good. Is it worth doing the swap? I am good with a welder if needed but dont want to dump a ton of money in it.
any advise would be great.

I'd buy the bike for that much regardless if you're going to use the engine in the Blaster. You could easily make money on it.

 

[darederek]

yea i would definitely get the bike then look at the mounts and make a decision. you will b able to make money or make one sick ass blaster!

UPDATE Re: 2002 blaster with a yzf 600 motor?

Well along story short i got the 600 motor and sold it within two hours for 1300 to a guy for his midget car!
I decided to take a closer look at the blaster motor so i pulled it! It appears that the stator was f***ed and locked the flywheel. I pulled it all apart and the gears and piston move freely. The crank case is busted as you can see in the pic and i found one on ePay cheap.also needs a new flywheel and stator. My big question is the piston has some nicks in it should i replace it? the cylinder wall looks good so can i just get a replacement piston?? any help would be great.

last pic i had to upload.

sweet deal. with 1300 repair the case and then don't worry about the cylinder and piston just big bore that thing!!! or fix it and make some money (less fun) just my .02

 

[mrtwelvevolts]

I want to ride and enjoy the quad for a little while before i sell it and i dont want to sink alot of $$ in it doing a big bore. should i replace the piston or just reinstall it and hope for the best?

 

[mrtwelvevolts]

hell so many piston kits on epay??? i have do not a clue on what i would need...I guess i am a little outa my sand box!

I would hone that cylinder and put it back together and run it till it drops, or you sell it.

 

[mrtwelvevolts]

Thanks but i own a company that installs security cameras so i should not mess with a hone! I did find this though....What do you think?
600cc late 90's motor for 150 or best offer, low miles comes with computer and radiator and all other componets there too. Should run with tlc been sitting for awhile but motor turns over tries to fire. Will remove listing when gone thanx for looking

I'm confused, what does that have to do with a hone? Also if you pick up the motor you would have to fab up custom motor mounts and mounts for the radiators and everything else.

It was suggested in the thread that i hone the cylinder! I can weld in some mounts and wire tie a radiator to the frame. But honing a cylinder and matching the piston and rings then jetting the carb to match???? not really my cup of tea. I just want to know if i should replace the piston and rings or use what i have? it is a simple thing to swap parts but one you change the factory engine parts set up from stock you really need to know what you are doing. i.e i can bolt in any running engine and make it work but anything beyond that i need you guys!

it really reminds me of my old neighbor who could not get his chevy truck running...NO Compression!! He ran a hone through it for hours with no luck! I know i have one cylinder and a cheap quad and he had 8 cylinders but i am sure i have no business honing cylinder walls! any good mechanic reading this would appreciate my honesty.

id throw it back together the piston dont look bad. mine had a ton of dings in the top from the rod bearin goin, n it still flat out f in ripped

Thanks dude! Thats what i will do!

 

[blasters/banshees]

ivv had pistons with cracks in them and it still ran put that one back in and run it

I can tell ya, fixing the air cooled 200cc yamaha blaster engine is WAYYYYYYYY easier than fabbing up everything needed for an engine swap... especially a 4 cylinder engine swap. Most of the race bikes (CBR, YZF, GSXR) use downdraft carburetors (or downdraft throttle bodies for the later models with fuel injection) and ram air pressurized airboxes. The airbox can be modified so that it's not ram-air (you'll lose like 4 hp off of the top end) but getting around the downdraft carburetors is TOUGH. They go right where the bottom of the fuel tank is...

Unless you have plans of drag racing this quad, there's no need for anything more than a decent running blaster engine. They put out PLENTY of power for playing around, trail riding, or even (in class) drag racing...

If you're concerned about your machining skills, take the cylinder to a local machine shop and have then power hone it for you. They'll charge a few bucks and you'll be back up and ready to go in no time.

Order a set of cylinder rings, move your carburetor needle 1 clip down and begin the break-in procedure.

You'll fall in love with 2 stroke power before you know it.

Best answer yet..Thanks a lot.
I found that the motor is not seized, The flywheel was locked up against the chewed up stator. I am looking for a good deal on a stator flywheel combo on cl or ebay but they run kinda high.
once i get those parts i am going to throw it back together and use it as a lake toy. I am also looking at yz250 or other dirt bike motors to pop up on craigslist because it is my understanding the most of them will almost bolt right up. lost of people on cl are basically giving these old dirt bikes away and they just have a gummed up carb.

 

[brandoz28]

almost bolt right up isn't right, they do bolt right up after you put in all new motor mounts though

Stators and flywheels arent cheap in my experience. I was lucky and got one off someone on here for cheap, but most the time theyre pretty pricey.

What sicivicdude said is pretty much what Id say though. Honing is cheap and rings are too, easy to put in, and jetting is easy too.
