How Light is Your Flywheel? *PICS*

[best]

Holy sh*t? 10lbs.........dude that's like half the flywheel weight......no wonder it ran like sh*t.

Naw, it was like 1/4 of the weight, but it was mostly off the outside diameter, so it may have been like the effect of 1/2 the weight.
Shaved it just the thickness of the ring gear down to the pressure plate bolts and quite a bit off of the back of it. Like little3mil suggested to AWK08, I had to try it!

little3mil was more than a bit harsh, but it is a point well taken. Give it a try, THEN tell us what you think.
Far too many folks just jumping on a bandwagon, "YEAH! What he said!" Not that AWK08 was doing that.
You don't have to make EVERY mistake before you get a sense of how things work. Good to have a bit of experience (lessons learned) though!

So, that 289 and my KTMs that I put lightened flywheels on were freakin' sweet when they could hook up and rip through the lower gears, but I am being honest about the cost and where the advantages were. With low power lighter flywheel weight may have some advantage, especially with low gears and on pavement, but significant power usually needs some taming down unless you have great traction.

Sorry I don't have a better picture with the cover off, but as you can see I have quite a small diameter and light flywheel on my Blaster at the moment. True, my present tires are pretty crappy, but with 45-50 hp, wheelspin is a problem even at speed on pavement.

That's why you only take off a little bit and not enormous chunks out. The stock flywheel weighs just over 3lbs so taking 3-4oz out of it is only removing like 9-11% of the flywheel weight......I've heard of people taking 12oz out of Blasters before.....about 25% the weight. By comparison a YZ250 flywheel weighs almost HALF the weight of the Blaster flywheel....obviously off of a dirtbike, but for the people that have done YZ250 Blaster swaps, they don't seem to have issues. I find the stock Blaster flywheel to make the engine slow revving personally...probably the slowest revving of any 2 stroke I've ridden. May you get some wheelspin by lightening it?.....yea......maybe......but I'd rather be popping up into the powerband then being caught dead out of it for a couple tenths of a second and then falling behind because of it.

lol such strong opinions over something so stupid... im still saying its a matter of preferance and why we keep trying to sway each others opinions is beyond me.. awk hates the idea for some reason.. ok thats his perogitive. others like me think its a good idea and a great mod, i have seen multiple blasters with it and they ran great, no issues with low end or stalling. and isnt kgibson getting a lightened flywheel for his MXblaster? and again thats just MY opinion so how about everybody shuts the f**ck up about it?? haha

 

[Paulie B]

ATV's dirtbikes, cars, why don't we talk about weedwacker motors???
Here's a pic of a stock CY 23cc flywheel:

Here's a thinking outside the box extreme lightened one:

What effect did it have? Bad idle- had to raise it.
Uncontrolled wheelspin- could be a + or a - haha
wheelies, 60mph on stock gears (among the fastest on the planet), and a rpm counted verified 22,000 rpms (among the highest ever achieved)

 

[super noober]

hahahaha that is AWESOME paulie!! how 'bout a vid of that lil bastard going up the road??

 

[Awk08]

that seems to be the problem here, we have a handful of guys who think there is only one way, and what works for them, with what they're trying to acheive with their drag port based motors, and dual purpose blasters, (sometimes on the trails, but that 300 ft. time being most important), that is what is best for everyone, forget us guys who run tight trails and have no need for a high rev motor, hence why we don't run 14/40 gearing either, as top speed at 300ft. means jack sh*t,
and as soon as I, being the only one, who will question these mods as being best for everyone, like they seem to believe
they get there panties all bunched up as a personal shot at them, their bikes, how fast they are, or even their builder, which it is not
it is just to show some of these young ones, who may never even see a 300ft. dragstrip, that this mod is not for everyone and their type of riding or riding area, and not to just jump on the "drag mentality bandwagon" without being informed to both sides of the coin,
and as for the "over harsh" comments towards me......
thats daily on here from this bunch, but you won't see me pickin any wedgies out if my ass over it

I also lightened the cutch, clutch arm, and piston.

It really is up to the person weather it's a good mod or not
I remember a while back you could actually buy flywheel weights for the CR500 to make it more of a woods bike.
Someone should try that on a Blaster- like you, be the first!

 

[super noober]

OMG PAULIE THAT IS AWESOME!!!!! how fast does it go? im guessing like 70-80?

About 60 in the vid with the stocker gears (17/57's)
I also have 19/55's and 20/54's- which would prolly pull 80+
The problem is finding a spot to wind them out and controlling it at that speed.

You were the one that came in and said it was a bad idea.....we simply posed the thought and shared our experiences. I ride trails and would appreciate the quicker revving and run 14/40 gearing on fast trails and top out every now and then, but mainly because I don't feel like going through gears every other split second up and down in gears 1-3 with 13/40(or lower) gearing.....hell a couple of the guys that went on your little trip last year ran lightened flywheels and taller gearing.....did you seem to notice it? Now if it was an MX heat, that's another story. We aren't talking about drag racing, we are talking about being able to control the power and have it at your fingertips instead of waiting to get in and out of it.......and I don't care who built an engine.....if you fall out of an ideal powerband even on a 4 stroke, it kills time even for a split second. For those of us, that like to mod to improve performance, it can be a desirable mod if it fits the bill for a particular rider and quad setup.

LASX was asking about flywheel weights. I don't think he wanted to run them but was interested in them and wanted to see if anybody else knew of anybody selling them specifically for Blasters. They can be nice for some MX tracks depending on the transition from corner to corner and on/off throttle sections that aren't straight and keeps momentum, but I usually see people running lightened flywheels at tracks. Even so, that's all rider dependent and even more so, track dependent.

A 10mph gust of wind will topple it like a hurricane at 80mph.

 

[Awk08]

You were the one that came in and said it was a bad idea......

the words "bad idea" or anything resembling that were never typed from this computer, what was is that mx racers and serious, harcore trail riders
(not groomed tracks, or trails like busco, croomed, silver lake ect. ect.)
have been using flywheel weights for years. period
so the masses now have an informed choice to make, not just jump on the "only one way" bandwagon
i am thoroughly sure that a lightened flywheel is a great mod, for some types of riding, but definately not all.

when you lightened flywheel boys are tryin to clutch it, or stall it, while tryin to cross a 2 ft. high log on the trail, or 30 yard long boulder feild on the trail, and i cruised right over it with engine momentum, i'll be waitin for ya at the end of the trail

if you can't see the negative effects of a lightened flywheel on serious hardcore trails, your using your drag based tunnel vision.
for every positive effect a mod gives you, there are trade offs also, why when i point that out, do all the panties head for the hemorroids ???

Yeah you wreck at 80 you buy a new Baja.
I haven't seen the spacing of the magnets in a Blaster flywheel but if there is some in between the magnets adding weight could be as simple as wedging some material in between them with epoxy for good measure.

Why are you even riding a "sport" ATV then? Go buy a utility. This isn't a log and boulder climbing challenge. I can go throw 500lbs on a Blaster flywheel and it isn't going to be outclassing a 4x4 over boulders and logs. 8-|

There is spacing between it. I'd rather use aluminium alloy though. Epoxy would work good, but it has to be of even consistency, no air pockets, and shaved down to preference. I think there are 4 slots on the Blaster flywheel.

i outclass the utility's everyday on this mountain, the blasters light weight and my riding there for 30 years will do that to ya, same as if i come to your area, you'll likely own me.
my point exactly here, the lightened flywheel isnt for everyone, everywhere

"This isn't a log and boulder climbing challenge"

/\/\ here it is, as it is alot of places here in western pa. coal country, and there are quite a few of us from here on bf.com, sure it would be nice to have groomed sand trails to ride, but we don't, so we have to learn to ride what we have

What I meant was using the epoxy to hold the weighs in similar to what the factory used for the magnets.
