blaster enigne mods

[blasterboy427]

i was wondering what engines out of other yamaha quads or dirt bikes i could possible buy and put into my 2000 blaster, cause i really dont feel like rebuilding it and i want something with alittle more pull out of the corners. if anybody has any ideas or you have done something like this before please help me out! i would prefer a 4 stroke engine cause im sick of 2 strokes even though i love that smell haha. THANK YOU!

any motor you try and swap into the blaster is going to take a ton more work than rebuilding the blaster motor. if your wanting a 4stroke motor then sell the blaster and get a 4stroke bike.

Many people have done the following swaps:

DT200 (I'm pretty sure that certain years are direct swaps)
YZ250 (Talk to 3Wh33lRid3r, he did it and just got it running)
CR500 (Someone around here did it, use the search box)
Warrior 350

I'm sure there are more, just gotta look outside the box

i was thinking about that put there was alot of money put into this blaster before i bought it and i was gonna race it im up for the work with swaping the engines i just need an idea on what will fit in there

 

[blasterboy427]

yea i was looking at yz250 engines but do u know what i would have to do to make it sit in the frame right?

 

[Surfrjag]

anything will fit in there, you have to custom fit it. i saw a 600gsxr motor in one before. would that get you out of the corners faster?

 

[blasterboy427]

yea and prolly make me drop a load in my pants haha i dont need that much power just something i can race at our local tracks friday night

For as much money and time youre going to spend, if you dont have a high knowledge/skillset/access to custom fabrication, you might as well do a rebuild.

For 500 dollars, you can have a pretty damn quick blaster. Not to mention, if you find some random motor, you dont really know when it was last done, and they only get so much use on em between rebuilds, so, you gotta take that into consideration.

Id personally just do a top end, pick your builder, have a trail port done, put a good pipe on it (even just a cheap FMF will wake one up and pair decent with a good porting job), maybe go up to a 30ish mm carb, and get it jetted and you will be REALLY happy with the results.

A ported, 240 big bore kit properly done will make over 40hp. 40hp on a blaster is quite a bit faster than a stock banshee. 40hp on a blaster is still keeping up with a stockish piped/jetted banshee. And I guarantee you, if you ever rode one of those, you woudlnt think you need more power.

Engine swaps are cool, and Id love to swap a Honda 250r engine into my blaster, but I also know realistically I dont have the fabrication skills necessary to do it. Most people dont either. Most people just wanna ride their shizz. So, trail port with a few bolt on goodies will put a smile on your face for sure.

i have a pro circuit racing pipe on it already and im pretty sure the piston the guy before me who owned put in a smaller boring kit

What do you mean a "smaller boring kit". Most likely it was overbored to clean the cylinder of any scratches an imperfections, and it was likely overbored like... .010 or .020 or something like that.

Just sending your cylinder off to a builder and having it scoped to see if it needs overboring or just honing (in which case you can just rering it), and maybe just have a trail port done for it.

Im telling you, that will be likely be cheaper and quicker than an engne swap. Theres a lot of power to be had in these little 200 cc air cooled engines. Theres something to be said about the simplicity of them and how cheap parts are for them.

You also have to consider what class a motor swap would put you in. You might be behind the 8 ball in handling.
