My cousin has a blaster and he's thinking about getting it bored to a 240. I have a feeling he'll be outrunning me. What do you think?

does he have anything else done to it? or is he just gonna bore it out and other than that its a stock quad? or does he have pipe, reeds, filter, proper jetting, and all the other stuff/

I don't think so.

The stock 400ex I think is faster than a stock 250r. And hes just gonna have a 240 blaster.

Maybe I'm just being bias cause its a lil blaster. Possible if he had v-force valves, a larger carb, porting, a Vito piston, and the head milled. but I don't know thats askin alot out of a blaster.

Definitly, I'm not just saying this because I have a Blaster either, but it's a proven fact. My Blaster with an FMF Gold Series Fatty Pipe, Powercore II Silencer, Boyeson Power Reeds, Wiseco piston, UNI Filter, airbox mods, etc. already has out-run a few slightly modified 400ex's. I just got my motor back from a new company called Hollywood Dirt Productions. They bored it .20 over, shaved the head, port & polish, and gave it a carb rifle, I will definitly stay ahead of most 400ex's with these mods. Although... a Blaster will never have the low-end and handling of a 400ex. -s0

I think he is also gonna get a Fatty Pipe for it (I think FMF or something makes it) and a k&n filter. All I know is stock vs. stock I win but there is no way I can leave him. I get him through every gear but not by much at all.

a stock 250r does around 72 mph. a stock 400ex does 60mph
stock vs. stock a 250r will EAT a 400ex!

a stock 400ex definitely goes faster than 60mph and a stock 250r does not go 72mph and if a 400ex does by some minute chance go 60mph I know it could pull another gear if it had one. And its stupid to compare which motor is better by its top speed anyways. I think it would take a lot of motor mods to make a blaster beat a 400ex mainly because it has to more than double its horsepower just for the top end hit and the gears are really close together and could probably only top out at 60max unless you put wider gears in the transmission or change the sprockets which just makes all the gears taller.

i dont know about stock but my piped 250r hit 74.8 mph in the 1/4 mile with stock gearing and original tires. i have the 86 which has the higher 5th and 6th gear though. i think a stock 400 is around 64-65. i think a 240 blaster has a very good chance of beating the 400 if he gets a pipe also. he wont beat u on top speed but he will beat u up to his top speed. even if the 400 has more hp than the blaster u need to remember nausty that it has a very quick shifting, close gear ratio transmission, plus its alot lighter than the 400ex. i remember the days when i wanted to put a 240 kit on my old blaster.... but then i said screw that ill just buy a 250r. now when i ride my old blaster i realize just how big of a turd it was. one day in the future if honda comes out with a 450ex or yamaha comes out with something fast and dependible i might switch to a high tech 4 stroke but i will never get rid of the R i have become way to attached to this thing to ever let go.

lol I dunno if I wanna sell the yz80 and a guy is wanting to buy it. I think i'm kinda attached to it also I lived in a apartment during the week for my dads work and the first thing I would see when i woke up was my yz80 in front of me and when i went to sleep it was the last thing I saw. I would take out a chair and just sit there and stair at it and look it over and clean it and give it a little love tap before I went to bed.

i have a blaster that is pretty much stock, it has pipe, silencer, reeds, and reedspacer, and a filter, and i keep right up with 400s, so i dunno about a 240. my friend with a blaster puts out 40hp. thats alot for such a little bike, and he says he bashes on 400exs all the time, sometimes even slightly modded ones.i dunno

yea...hahaha...Matrix, your stupider than you look, if its possible.

CT Racing sells a billet blaster 240 head that puts out about 40 horse. There are a ton of them in oregon around florence and winchester bay. They run damn good. They run right with the piped shees because of their weight. With like delta v-force reed valves, carbon fiber reeds, bigger carb, port, 240, lots of compression, and the right rider he will eat your 400 like it was a 300...

06-22-2002, 02:33 PM
When i all i had was my K&N air filter in my 400ex it went over 70mph, 60mph!? your real smart ha. Screamin shee is right, they do have blaster doing over 40 hp

I agree. Why do you people care about speed? Damn 65 MPH is fast enough for me. All im saying is be happy with what you got, ride hard, and enjoy what you have and not worrying what quad will go faster than yours! So what, maby a Raptor might be faster than my 400ex, BIG DEAL! My 400ex goes as fast as I want it to. You tell me where you can get a quad up to 75 mph on trails and such? What im saying is speed does not matter, its also how the bike handels and performs, etc. Its like somebody said earlier, a Blaster MAY go faster if its modified, bored over, etc. but it will never have the handeling and performance and reliability of a 400ex!

Personally, whoever has the Blaster thats getting bored over, I would just sell it and get a 300ex/400ex/Banshee/250R/etc. Blasters are too small and short and have poor handeling compared to the other quads I listed above. And if you STILL want more power or whatever, you can always slip on a pipe, throw on a K&N filter, Jet it, and bif bam BOOM, you got speed....!

If your going to compare the top ends between the 2 and 4 strokes, why don't we just compare the bottom end pull between them while we're at it.

heres the dyno on hte blaster for all u non believers

Yep is true, a 240 blaster will walk all over a stock 400ex. You gotta think of the power to weight ratio.

06-22-2002, 06:21 PM
It looks like I'm gonna have to get a little faster. I mean come on guys, I can't have a little Blaster walking over me on a 400.

Have you ever seen a 400ex, do 65 mph around a mx track...
i didn't think so (unless it has a lot of stright aways), the only way to find out is put the friggen thing on the track or trails and see who will out pull who in tight corners or jumping.................

i highly doubt the blaster will keep up, unless it is stuck in a 250r frame like rath did with a blaster, with pep shocks, axles, a arms, other words i don't think that the blaster will keep up on a track or trails....

240 blaster will smoke a stock 250r according to ct racing i think maybe it was duncan racing...i dunno where everyon gets the idea blasters are slow

06-23-2002, 12:19 AM
well, first off, how many people race or hav stock 250r's??

06-23-2002, 01:02 AM

ok this is just a question but isn't there 2 differant techniques to dyno'ing because i'm assuming that little line in the dyno with the 18.9 was the stock blaster hp and in most of my mags it is usually 13.9 and I have, cross that, had a blaster and that seems about right compared to the power of my 400ex but a while ago this question came up on the hp on the blaster and one mag said it was 18 somthing and a bunch of others said 13. somthing and somone mentioned how they usually put it in 4th gear and leave it because thats usually when the motor is on a 1:1 ratio sept on a blaster its really 6th if I remember right and I don't remember how the other way they did though.

Nausty
06-23-2002, 01:41 PM
ok here is the gear ratio on the blaster it should of been done in 5th gear then right?

EDIT: oops I just noticed I forgot to paste it if any doesn't beleive me I could find it again and the link but 5th gear had 1 to .995 ratio if I remember right.

i've raced a 240 blaster... 1st time i raced him i ran 18 tires with a 16t sproket... almost the same as stock gearing of a 400ex... he had on 22 tires and 1 tooth up sproket for more speed... outta the holeshot i pulled him by 4 bikes till i grabbed 5th topped out and he ran right next to me after that...

went back home switched over to 20 tires wit my 16t front... went back up lined them up again walked all over him... i pulled 5 or 6 bikes the whole time...

now all u people that say u race theses modded 400ex... what gearing, what size tires, and what where thses supposed motor mods!!!!

11-30-2002, 09:01 AM
dude of course gearing and tires count in the race btw he runs wit 14/40 gearing and 18 inch rear tires:D

Stock 400Ex= 60mphs. Ummmmmmm. No.

All 400Exs are different. I don;t care what anyone says. It all depends on how it was broken in, who put it togeather. Where and When it was made.

I know that my stock 400Ex when I got it was hitting 70.53. If i can find the ticket and the read out from the computer at D and D cycle Iwill post them.


And right now my 400 only does about 60. Forget top end. It is dumb and usless. gear as far down as you can and feel the power down low. and then go race MX.

well i have both bikes..look in my sig..and ive got mx's on the blaster with 1 up tooth on the front sprocket and well the blaster is a lil faster on top.. a few bike lenghs only both its extreamly fast for a blaster

I doubt it, they handle like crap and the gears are so close together hes gonna be spending half the time shifting. That and it may have a little more hp but the 400ex will pry have a lot more torque and a lot wider powerband.

Well if you go back and check the date I originally posted this, you will see it was a long time ago. Things are worse now, he sold it and got a banshee.:devil

My neighbors all have blasters and they are all decked out. The one I usually ride with though has reeds pipe and all and I think his my be a 240 not sure, but before I had my mods for my 400 I could still blow him out of the water. Remember a lot of it is the rider. hope i could help

Ryan

Well now that he has a banshee you could say goodbye in a drag race. On the track its more the rider but the 400ex is put out for the track better. As far as for the blaster with a 240. I have a blaster with FMF Fatty pipe, Power Core 2 Silencer, Pro Series Power Reeds, Bored .10 (Melted the wall so had to bore it) K&N Air Filter, Wesico Piston and whatever else I got. (Holeshot XCT tires). Last time I raced a 400ex it wasn't bored and I needed a top end, I dragged a completly stock 400ex and right off the start he beat me but once I hit second gear I was coming up right aside of him. He still beat me but there was good competition.
