fly wheel lighting how much

I believe it helps throttle response, less rotating mass. Which leads to a little more HP too. I'm pretty sure either Kennedy, Wildcard or Flotek can do that.
It makes your motor spin faster and rev quicker. I dont know how much I would ask a mech. on here flotek wildcard or kennedy power
When I was at Kennedy power for my engine work we talked about lightening the flywheel he does not reccomend it at all.
I wouldnt do that ivv seen a lot of people having problems after doing this well like 2 outta 20 blaster owners I know this happen 2 when they do these type of mods, they where build this way for a reason
Yup, it is possible to lighten a flywheel, but its not a good idea in my opinion. I'm no professional engine builder, but from what I know, attempting to lighten a flwheel can upset its factory balance, and this vibration may cause it to fly apart at speed. Just what you need, a grenade waiting to go off down between your legs. Also, a flwheel which is too light will interefere with the engine's ability to idle, and low-end torque will suffer a bit due to the less inertia present in the smaller rotating mass of a lighter 'wheel...
very well said....you know your sh*t man always there to explain things very well...have some rep
well i guess all of you will be the first to know when mine so called "explodes".....and yes it was rebalanced
so how did it effect starting out in first gear and when in tight woods?
alot of guys with yz250's set up for the woods use fly wheel wieghts to help keeps from stalling out and mellow out the hit.
I would think lightening the flywheel on a heavier machine would not be so great and make it more sensitive to gear selection and having to be more active with the clutch.
i havent run it yet.....but yes i was aware of those exact syptoms when my builder explained it to me, i have spoke with many guys that have this mod and it does take a little getting used to as far as learning to clutch diffrently, but the gains far outway the "scares" for my setup and and the type of power im looking for
alot of open running, hill climbing, almost dune type riding....im planning lotsa trips to rausch creek in pa.....thats kinda why i went so heavily modded, i can really let loose there........but i should also not have any probs in the trails either....itll take some getting used to but no prob!
Mine's lightened, been running it for about a year now with no issues. Runs and idles fine, and it's nice and responsive. But yes, you kinda have to learn to clutch a little differently from a dead stop, probably wouldn't recommend this mod if you ride a lot of technical type trails.
Well, it's not so much that your clutch feels different, it's more like you'll be working your clutch a bit more. The best way I can exlpain it is that your blaster will feel more like a 125 than a 250. That's a very extreme comparison obviously, and it's not like your losing hp or anything, it just kinda changes the characteristics of the powerband. If I remember right, I paid $40. Flotek did mine, but I'm not sure how much weight was taken off of it. Talk to one of the builders here and let them know what type of riding you do, they know more about it than me.
Blaster flywheel can be safely lightened. Already been said, call sum builders. It's just not really necessary unless you're lookin for that shred of advantage over the competition. If yur not racin it really ain't worth the trouble & price. IMHO
Apples & oranges.
My YZ250 flywheel = 35.5 mm x 100 mm @ 766 grams
My Blaster flywheel = 45.5 mm x 117.5 mm @ 1389 grams
Blaster has much bigger dia & almost twice the mass.

We have run a lightened flywheel for years and have not had one come apart. I lighten all flywheels on the engines that we build, it makes good sense. Our 3mm stroked 200 motor did not run a counter balance either. I have only seen one come apart, this was due to the guy had no clue what he was doing when it was lightened.
We charge $25 for the lightening plus shipping back to the customer if anyone is interested.
