Lightened flywheel Idea.

He my friend lightened a flywheel for me and it worked BAD AZZ! He basically took some material off the edge so where the magnets are is now the edge of the flywheel. My bike gained 500 RPM unloaded and about 350 RPM loaded. I used a GPT tach for all my testing. And best of all you can now set your coil gap VERY EASILY. since the edge of the flywheel is no longer there to hide it. Heres some pics incase you guys wanna do this to your flywheel. i'm sure anyone with acces to a machine shop could do it.

what happened to the other post to did on the flywheel?

were doing that now on a race motor and are trying to get even more material off. For someone who has lots of time on their hands could remove material from the top portion of the fins

What if you cut out every other fin?

i guess you can do that but the fins are there for cooling...ive never tried it to see if it hinders performance or cooling so maybe you can try it

lol @ Chris pretending he's busy. btw, you got that dyno yet? We really have to get the temp probes out and do some measurements before and after these flywheel mods.

that yours bleh? i have snowboardgeeks motor maybe ill test doing that on his

kool....thats what i was wantin to see....but i think the other mention is what made the other post vanish...umm...sorry.....but i think i will put it in the mill and try sumthin a lil different too.....

oh yeah.....how much shorter are your fins now from what they were

I think "THE MAN" sent it to another dimension. the top of the fins on my flywheel weren't cut that much maybe 1/8" - 1/4".
Than "no fin" flywheel looks sweet. But definatly have somethin to moniter head temps when testing it.

i did this on the cag about a year ago. i use a 650 starter motor to start my cag ..i have recently have modded my x7 with the josh head i had lying around for months didn't like much for a cag ....

Can't really tell what i'm looking at? did you shave off all the fins, take the pull start off and make your own cover? what kind of flywheel is that it don't look like a stock one.

everybody scratches there head when they look at it LOL ,it is like the pic blan has (it was a stock flywheel) but i modded it by removing the catches,fins, and machining the OD down and machined a cone for the electric starter.

when you say josh, you are referring to the infamous ip2, correct?

yes ip2/josh all the same guy.these heads have been around for some time now.the same one bad *** has.to make it clear it is the head thats on the mid bike x7........the other one is the one i made over a year ago for my cag.

did you use an old scooter head for the cag? i've found that honda spree nq50 heads have the same bolt pattern.

no i made it ,it is a two peace head

thats a watercooled flywheel lol no fins needed...

It was made for my motard, it's got a big scooter head, runs on methanol and the cylinder is turned 180 degrees so the exhaust header is not heating the air before it hit's the head, still i would not stand around idling else it would get hot fast.

fixo, i like the cone idea, what compression is the head running and does the starter start it easy?

IDEA!! Remove all fins and weeld bigger "fins" on the cylinder

i'm running about a 15:1 .yes the starter works well, i use a ford relay switch on the back of the starter and a micro switch to activate it.....my main problem was early on, the stock pull starter was a peace of shi& and also stuck out on the right side which made it easy to drag a peg on right turns. i'm now able to bring in the peg tighter to match the other side..i made the over size head to be able to eliminate the fan and lighten the flywheel my next mod is to adapt a polini pull starter ...i speak up on some of my mods because most of what i have done is being made in the after market world now...i have adapted a ysr style reed block and mikuni 16mm carb and works well. i'm now working on a new reed assembly and a new and improved head...
