How big can a Blasty engine go?

['00 WO-YA!]

Alright, I'm trying to gather a lil info. How much displacement can be had from a Blasty engine? I've seen bbk up to 265 & I've seen +4 stroker kits but I've never seen a bb stroker. I'm sure a custom piston could be built but I'd like to know what's off the shelf? Also, if it is possible, is it necessary to use a shim between the base & jug? In most applications the wrist pin is just moved in the piston but it seems to me that a shim could be used to keep port timing correct & still use a typical bb piston with the stroker. Hope I communicated this well enough, Lol!!!

this opens up a whole can of worms!

if you're wanting to go big, I'd go with the LA Sleeve BBK and a hotrods +4, but have the rod replaced with one that measures 115mm center to center. and have the custom machining/porting done to really make it work together.


this is IMO the ultimate blaster powerplant that keeps with the original blaster motor. This is going to take a pretty big budget, but it'll be a great, rip your arms off powerplant.



In any way as I have said over and over, build the suspension first, then work on the powerplant.

Depends on your budget and what kind of power your looking for.

IMO if I had no budget I'd go with a DT200 swap. Go DT240 big bore, ported and matched to the +4 stroker.
Makes 33 HP before the BB, porting, stroker.

LA sleeve BB cyl with the +4 ported and matched would be next in line.

Haven't seen a 265 in a while, pistons are on short supply for 240's so i doubt itd be easy getting one for 265 let alone an overbore.

(They made 310cc BB back in the day too)

where do you get the 310cc kit?

Was it reliable or a race it rebuild it type of setup?

^ Sexy machine in that sig! Back on topic, I'm 6'2" 230lbs, I've got a coupel of toys that I'll post up in the sig & Had a '95 Blasty (Purple/Black/Yellow) back in the day (wish I had it back)!
Anyway, with my size my Warrior fits me good & I have a spare Warrior chassis, my only gripe with the Warrior is it's underpowered, granted with a lil work it can pick up but I'll always love smokers. So, Blasty engines are plentiful & I was thinking of trying to build a big, nasty, large displacement setup that'll move the Warrior chassis. I honestly don't currently have a Blaster but I've been workin with the 2 that my 2 cousins have ALOT lately & I just have a hoot with em, hands down, Blaster is the best bang for the buck in the ATV world, jmho!

Thanks bro appreciate it!

Id go a little more balls out if i was going to swap a 2 stroke in your warrior and look at maybe a dirtbike engine swap.

plenty of ridiculous power to be made with most of them and you will need it since the warriors quite a bit bigger than a blaster.

 

[brandoz28]

a stock yz250 motor may be a better choice than a built blaster motor

 

[Budget_Blaster]

f it were me though id probably build the 350 thats in it.

Most of those 4 strokes run a pretty tame cam profile and a cam swap usually is like night and day.Then if youve got any other mods they are usually complimented by the swap.

I dont know what kind of riding you do but a simple sprocket swap could add a little pep in your warriors step too.

Arent the warrior 350's the same as raptor 350's?

trinity racing used to make them, they also had a 265,285 and a 350 bbk.

That was awhile ago though.

i run a +3 stroked airsal bbk, but the displacement only comes out to 237.5cc with the 71mm airsal bbk. IMO the +4 crank is overrated.. both of these blasters are powered by vitos +3's and there aint a +4 that can touch em. size dont matter (lol) quality porting and proper setup is where u make power I:I

I'd really like to come across another YZ465 parts bike with a running engine or atleast a repairable engine. I have an '80 that's a pretty good solid bike but I really don't wanna pull the engine from it to put on another project. I've thought about a YZ250 engine but some people even say they think that's a lil on the small size. I figure part of the Warrior's weight issues are the engine itself man, it's huge, side by side on the floor with a Blasty engine it dwarfs it, gotta have atleast 20lbs or more on the Blasty engine, not counting the starter & stuff. I have some stuff for the running Warrior that I have, cam, springs, etc, just need that jug bored & gonna go 12:1 with it. The plans I'm talkin about in this thread are for a spare chassis I have.

 

[blasty 95]

Yeah yz 465 needs to stay together would be cool on quad but I like the dirtbike its cool an vintage!! Man u should look for a blaster roller we got rims wiring coils stators haha arms swinger etc...

 

['00 WO-YA!]

I might have to do that, I'ma see how I like yours with the swinger & then maybe try to find me a '03-'06, somethin with hydro's to slow my chunky butt down, lol! + I kinda dig the "Predator" alien look, lol!

 

[blasty 95]

Not a four stroke!!!!!! Get a lt 250 trx 250r anything lol jk man scoobs banshee would spank dwyanes a** all acrossed the yard an his predator is decked out..an if ur going to pay the money for the predator man get a carb yfz 450

a yz250 motor will put out the same amount stock as your usual built big bore blaster motor. then you can start modding it up and have a really killer motor. I think that for the money invested this may be the best way to a killer yami-mutt

 

[96MXBlaster]

if someone does a yz250 motor swap i might try it if it doens take alot of modding

there are a few threads on here detailing the swap. it's a lot of work and a lot of fab.

 

['00 WO-YA!]

+ for me I'd be doing the swap to a Warrior chassis. It might have a lil more room to work with but for sure it's still gonna be a handfull of work.

BLASTY 95, I wasn't referring to the Predator 500 Polaris, I was saying that I dig the "Predator" alien look of the '03-'06 Blaster machines, it's really grown on me & I like the fact that Yamaha upgraded the brakes on those models, other than that, same great bike!

 

[blasty 95]

Ohh lol the different hood duh yeah I like it but no purple ones some I'm stuck in 1994 lol na I don't mind the purple now that its getting a little faster!
