FLywheels timing and keyways

[christph]

I called the company I placed a sizable dollar amount of a order for those magnets. My guy sounded kinda quizzical about my quistion : ).
He had the info jotted down on my order alrighty, right down to custom mold specifics.
These (and basically all cycle flywheel magnets subject to high heat) are ceramic. That just happens to be the number they get "zapped" at.
Not much strength really when measured against neo-deoam (sp?) Or the sevral other types of materials that can be made a magnet and "zapped" to different degree,,,, kinda surprised me since I had these tecate magnets marry them selves together with force enough to break in half on bench (bad day in garage for sure !).
So yeah, own a mold, rights with this company for tecate magnets ~ cool. Ain't gonna be scrounging for the no longer.
I am hoping for a 5 year payback on my investment,,,, we shall see. Dam sure want to be the Tecate flywheel go too guy ! KDX bike + Polaris too.
Heck of a hobby ehh

Are you planning on restoring old flywheels or building whole new ones? Personally I like the idea of fully encased flywheels like Honda's 250R. Ricky Stator sold them for a while but ran out before I could snatch a couple up.

restoring back to usable condition, better then before IMO

Are the kdx flywheels the same as the kxt flywheels? There are some on ebay for pretty cheap:

Nice. How much weight does it add? Does it change the how the engine feels, i.e., how quickly it revs out, tractability? How much do you charge? And finally, if the magnets are still glued (as mine are), do you just add the casing? You don't pull them out and re-glue them I assume. Thanks.

3 wheel, the kdx are different timing,,,, keyway is cut different.
Kdx guys was buying tecate flywheels and having the keyway re slotted,,,, 86 thru 88 models I beleive,,,, not the encased ones,,,, don't know about those newer kdx flywheels other then they don't work on tecate.
1 year of kdx has magnets bass ackwards all together.
Same magnets though. So kdx guys have it much worst for flywheel replacement then us t-3 guys.
Here are 3 kdx flywheels. One on far right is yet to be identified. I know what it isn't (t'3).

65 dollars to clean up, reglue your magnets back in place ( if needed) + encapsulated and turned alot more true then stock,,, returned to you (stateside,,, international actual mailing cost).
Stock tecate flywheels are so FAR out of balance it's no wonder our Tecates cause hand tingle.
I add about 60 grams of material,,,, kinda varies somewhat but there abouts.
I can leave a bit heavier or lighten up some,,,, all dependent on customers wishs.
If any magnet needs replace they are 30 dollars each + 65.00 base price.

Thanks, I appreciate the detailed information and will be sending you mine in the future. Looks like you are the go-to guy for flywheels now. I called Ricky Stator a few months ago and he said it is very unlikely they will be stocking flywheels in the future. Apparently he has to buy 1000 of them and it is just too much of an investment.

Stock tecate flywheels are so FAR out of balance it's no wonder our Tecates cause hand tingle.

......And makes them 10x more reliable than it's competitors. That issue that you have uncovered could be the reason my uncle was tightening the mounting bolts before and after each race. John, have you run one of your flywheels and noticed a seat of the pants difference in vibration?

[jeswinehart]

I have never run my Tecate anywhere other then the sand dunes at Silver Lake State Park here in Michigan and to be honest, that is where I came up with the idea of encapsulation around the open magnets.
To answerer your question,,, best I can,,, mine still rattles the bars a LOT even with running one of my worked over flywheels.
But I gotta think trueing them up has to help,,,, these flywheels stock are like 9 thousands out of whack. In the picture on my lathe that is the high spot, the other side opposite is trued to zero. Kind of makes the lathe rattle about until I can get a few passes made.

[yaegerb]

Lol, holy...that's quite a bit out of whack. Yeah, it's gotta help a little. Too bad it doesn't eliminate it entirely. As usual, nice work with these flywheels!

[86T3]

Are you advertising this service any where other than here? I'd like to help get the word out for you on Facebook, I can post this thread or another link if you'd like

[jeswinehart]

The KDX forum I joined kinda sort of ,,, done one of those flywheels for a member there Joe but honestly, they don't know much of me. Not sure how best to promote really,,,, word of mouth is best way so yeah if you happen to hear of somebody needing some help please by ALL means put us in touch how ever that may be.
I don't think it wise of me to sell individual magnets on ebay due to polarity differences and human natures chance of screwing it all up
Depending on how many housings I can acquire I suppose I will have one on ebay at some point. I just like having a few on hand so I can get one right back out if need be. Some folks want their original back, some don't care and want it asap,,,, that's why I try to have some ready to ship out once I receive theirs as a core to re-work later on.

Thanks Joe, john

FLYWHEEL (FLY WHEEL) BALANCING

Now you are talking about something that I have a far more knowledge about and first hand experience with than magnetism, therefore, I can tell you that a flywheel is similar to any other type of wheel like an automotive or motorcycle wheel etc in that the center and the rim rotate around a hub that is mounted on an axle or spindle . A flywheel and flex plate on automobile and truck engines etc also work in a similar way even though they lack a "rim", and the ONLY way to ACCURATELY balance a flywheel is to put it on a balancing machine.

The best balancing method to use is the dynamic type as opposed to the static type . This means that even if Honda flywheels are more true than "The TECATE....The Most Powerful 3 wheeler In The Universe!" flywheels, it is still possible for a Honda one to be equally, or even further out of balance . This means that only truing a flywheel by machining it does NOT necessarily balance it or even improve the balance and can in fact unbalance it . It is also possible to balance a wheel that is a little out of true to close to "zero"/"neutral" balance, and this is done nearly every day in nearly every tire balance shop in the world.

OOPS....POST TO DO A POST CORRECTION CUZ I GOTS NO EDIT BUTTON CUZ THE STAFF LIKES TO READ MY POSTS SO MUCH THEY WANTS ME TO MAKES MORE OF THEM.

"...in nearly every tire balance shop in the world."

Should be.

"on nearly every tire balancer in the world."

And the wheels on the (short) bus go round and round...

If you know so much about it why wasn't it addressed during your extensive testing of these machines?
