what does he have in his motor, i dont thinik he will its all on the rider, get to know your bike before trying to race him because your going to make yourself look like a fool if ya get it and right away race him before knowing your bike

Even a pretty modded 300 won't compare to a stock z400. Again it will depend on riders but I think this guy is in for a rude awakening.

IMO i think a 350 gthunder kit in a 300 will make the 300 keep up with the 400 until the 300 hits the rev limiter and/or the 400 will take it in 5 gear...not flaming or anything though

I rode a stock z-400 the other day and it will take alot to the 300ex motor to alow it to keep up. I think that even with the 350 kit the z will win by a long shot.

Give me few days And i`ll let you know, my friend just spent 1600 bucks on getting a 330 kit installed in his 300ex he wants to beat a stock kfx400:p I keep telling him, dude just buy the z400 if you want a fast trail bike. He`s going to be really mad when I put a pipe on it.

For the $1600 for the kit, he could have sold the 300ex and bought a used KFX/Z cash.

I sincerely doubt that a 330 ex will even come close to a stock z400. 300ex is 15 rwhp stock. Kit MAYBE adds 5rwhp and that would be a lot. That means you're STILL down 13rwhp from the STOCK z400.

People think these "kits" give machines all kinds of power. Even if you're running a wicked cam, all kinds of compression, etc....you're still dealing with a 300cc motor....(give or take) and you can only get so much out of it before you need to get beefy rods, cranks, bearings, etc.

I learned over the years: Start with a good machine and you won't spend all your time trying to make it something that its not. Sure you can make a 30 hp blaster....but for the money you'll put into it you could have bought a nice 400ex in good condition that already has 30hp RELIABLY!!!! :devil:

My friend has a 450R and runs fourstroke B and he allways tell me how jeremy benson who runs sports class on a 300ex blows by him in the open sections. i think its a four stroke tech 350 but im not sure.

That's all rider there. A 450R will smoke a 300ex by a long, long shot.

No way can the 300ex smoke the z400.......

07-17-2004, 11:26 PM
Actually billdog you can get a blaster to much more over 30 horse power without it costing as much as a used 400ex.

blasters are cheap say you buy a used one for 1500, and a 400ex used for what 3000-3500?

well blaster theres a porting company called cpcustoms, that gets there motors up to 40 horsepower with jsut porting new pipe and larger carb, all adds to a lil over 600 buks.

o well anywasy a 300 ex puts around 16hp, and i msure the bore kit will ad more than 5 hp, but still wont beat a kfx

i own a 330ex and me and my brother have a Z too, drag racing the Z will win all the time, but through the woods i can beat my brother, it just depends on the rider

I have a 250x with a 298 stroker...Yesterday at my race I beat the only 3 z-400's on the track:);)

no offense but z-400's are nuthin special on the track without alot of mods...

Billdog350

Kraz, you're looking at pure cost. Of course you might be able to mod a blaster up to 30 hp, but its not STOCK. Additionally you're dealing with a motor and frame that haven't changed since 1987...there is a bit to be desired on the handling. I'm not saying you can't race or go decent with a blaster...but I'll bet you can go BETTER with 400ex. Stock vs stock of course you can't compare. However by the time you get the proper swingarm, a-arm, shocks, axle, frame, etc on the Blaster I think you'll find that you're close to the cost of a 400ex that you can turn the key and go at the flick of a button and not have to maintain like a 2 smoke.

wrong;)

thier dead even with 14/38 gearing but, the z does have a higher top speed

this is assumingthe z is BONE stock, even with a pipe, the z will pull just quick enuff that a better rider wont make the difference

and my 350 has a dyno proven 30 horse, with plenty of low end to spare if i wanted to sacrifice it for some more topend hp. and its plenty reliable so far and i'm only at 11:1 compression right now too, might try 12 or 13:1 later down the road

and actually, you can get an easy 40 horse from a blaster that will smaoke a 30 horse 400ex, and of couse it wont be as reliable, its a two stroke

Kurt's blaster over at PB has to be getting at LEAST 40 horse out of it. That things insane.

Again, here is a quote from cpcustoms website:

"The blaster is an excellent beginners sport quad and has the potential to make very respectable hp. A few of CPC's customers have had dyno numbers in the 38-41 rear wheel hp range with a 200cc stock stroke motor. That is a huge improvement over the 13-15 stock rear wheel hp that the bikes come with. CPC can port your blaster for many different levels of performance as well as different types of fuel (pump gas, race fuel, methanol). Whether you ride trails, mx, dunes or all out drag the port work can be custom tailored to your riding conditions."

blaster i think respond so good to mods its unbeliavable, i have 1 with the basic pipes and filter, but i also got reeds and reed spacer and just putting the reeds and reed spacer in woke it up alot, im happy with it but it still doesnt compare to my Z :)

XCAdam89
07-20-2004, 04:08 PM
You can't really compare the two, because they are not even in the same "league" but they are quick bikes for 200cc.

Billdog350
07-21-2004, 11:30 AM
That is exactly what they are. They're the quickest 200cc quad out there (and the only ones that I know of) and even possibly in the 200-300 cc class they're the easiest to modify and up hp. YOU are STILL dealing with a FRAME that is unchanged since 1987. The technology on the 1999+ 400ex is quite a bit different. You can't compare the two. My point is still that you need to MOD the Blaster to match the 400ex power, and then you'll STILL be low on torque and have an inferior suspension.

XCAdam89
07-21-2004, 05:29 PM
I know your point, but you can make up for the less than par suspension with the money you save, you can get a brand new quad for 3,199, with that money you save, slap some elkas on it and your back up to par.

Billdog350
07-22-2004, 05:51 AM
I still disagree. Some $500-700 shocks won't make up for poor ergonomics, poor design, and the smaller size. To make the machine handle properly you will need extended A-arms, extended swingarm, +2 axle, etc. Look at any SERIOUS rider out there who has tricked out his Blaster to 30+ hp and you will see that eventually they start focusing on suspension. No matter WHAT parts you put on a blaster, a 6ft 250 lb person will not fit on it as well as a 400ex. Ok, so evaluate both with a 5.5 ft person? Even so, the Blaster is narrow and short for them. I agree you can buy them for cheaper and trick them out easier...but as far as a good handling 30 hp machine for a given $ amount? A used 400ex will beat a NEW or used Blaster any day.

bradley300
07-22-2004, 09:00 AM
who cares what everybody says? blasters fit me well, so well in fact i'm selling my 300 to mod oput my blaster.

in the end, if you spend the same amount of money on a 400 and a blaster motor, the blaster will be faster in the end, as for suspension, if your serious in to racing, theres nothing on the blaster that you would end up replacing that you wouldnt replace on the 400 anyway, yes the blaster has worse geomtry, but the 400ex has out dated 1980's geomtry just like every other quad on the market, its not that high tech, just a little more rake on the a-arms, big deal.

on my stock blaster, i have no problems keeping up with a lot of the b class gncc guys on thier 450rs, yfz, raptors, 400ex's. but i dont even race them, my class is warriors and smaller, and in that class, a blaster does just fine, and yes, you can make a blaster go faster than a z400 also

07-23-2004, 08:23 AM
you can make any quad faster than any other quad with the right amount of money i think it all comes down to which quad you feel comfortable on. i know i felt cramped on my blaster and that was a couple year ago. my knees were always hitting the plastic i felt good on my friends 300 but when i bought the r it was a world of difference. none of the newer fourwheelers are really high tech. (besides the cdales/atk's) i mean they are getting to the point where they are the motors are and some of the suspension are on the higher end but were just not there yet.

a 330 can run neck and neck with a stock z. ask mickey dunlap or read the atv action artice on the four stroke tech 330, i know im not the only one that saw that.

How much does a 330 that's tricked out to run neck and neck with a z cost? Used Z= $3500. Used 300ex=$2000 plus $X amount of mods to make it as fast as a z. $1500 worth of engine and suspension sounds about right.....

My 400ex will smoke a z or kfx with stock for stock bore sizes not inculding the othe modds i have to my bike but its standard bore and it rippps.

Dylan227
05-30-2011, 04:26 PM
I think its mostly the rider and a little bit part to do with the bike. 300s are decently fast stock. But agreed a z is way faster stock. But 300s can be built to be seriously fast. As in faster than a modded z or kfx 400. Its just my opinion. My 300 motor make 38.7 horses on the dyno without mrx fuel. So don't say 300s can't be built. Plus 300s are lighter than the 400. So give and take its mainly the rider. Opinion though.

I think i just read the most retard comments in my life 300ex will never beat a Z400 in any kind of racing ! even built 300exs dont stand a change ! top speed of 300ex 56mph, z400 72 mph huge difference ! cant change top speed with motor work only gearing that would slow the 300ex down too much . yes you can spend thousands in motor work to drag race a stock z but then thousands more in suspention the race it ! that kind of money you could just get 450 !

Dylan227
06-28-2011, 08:53 PM
well you obviously dont know how to mod a motor. I didnt say a 300 was going to beat a z i was stating my opnion. And motor work deffinatley makes topend higher.

I rode a blaster for 10 years, then got a z400. They're not even in the same league. The blaster is a youth bike made for kids learning to atv. IMO its a little hot for that purpose, but it gives the kids something to grow into. 400ex and z400 are adult bikes.

I just shake my head whens someone dumps a ton of money into a blaster. Don't get me wrong, i loved my blaster, but its a KIDS BIKE!

My 300ex was built by Four Stroke Tech. 345 cc, big cam, ported head, stock carb, no air box lid, full exhaust, 33 tooth rear sprocket, 14 tooth front sprocket, modded rev box, thats it! That quad run REALLY good for a 345cc, Im not saying its the most powerful quad, but it was Impressive! There many times in the 2 seasons I raced it where it was no problem to compete with 450's in the GNCC series. So yes a properly modded 300ex will out run a z400. :cool:

Has the 400ex 300ex or blaster ever win a championship against other quads NO ! Z400 has won two against 400exs,yfz450s,honda 450,s even ran and beat alot of 250r,s ! to say a 300ex modded will beat a Z400 sure a stock one once you mod Z its game OVER! no modded 300ex,400ex,blaster will out handle or out power a modded Z . The Z has proven itself on and off the track and is still far better handling/power than ANY 300ex,400ex,blaster!
