Lightened flywheels - group buy?
 

I've been in touch with Millemille regarding getting my rotor/flywheel lightened.


He needs 5 people to be interested to make it worthwhile doing another batch.


Anyone else interested?


I'm waiting for a cost at the moment, just trying to see if this is likely to be a go-er.

Re: Lightened flywheels - group buy?
 

Just had a cost from Mike (Millemille), it's £145 for an assembly with steel bolts, and £185 for one with titanium bolts, both prices are plus p&p.

Re: Lightened flywheels - group buy?
 

For pointy or curvy?
Does he need my current flywheel or can he source one to lighten or even do the ride in/out service he provided previously with a deposit of course?

I'm unable to provide my own flywheel as my L2 is a daily runner but I would still be interested and just need to know what needs to be supplied.

Same price for curvy or pointy.

I need a flywheel from you, whether it's your current one or one you source 2nd hand, and it'll be about a 2-3 week turnaround.

Not doing the ride in/ride out unless you happen to be in the Peak District/Derby neck of the woods...

Re: Lightened flywheels - group buy?
 

Thanks for the reply, as above I'm interested but will need to source the parts. Keep me posted :)

Just for clarity you need part #2 for this?

Yes, part 2.

I can vouch for the work and the quick turnaround

If anyone needs a bolt to remove the flywheel, I have one to sell

And the starter sprag bearing housing as well...

So this whole assembly contains the necessary parts?

Yep

Re: Lightened flywheels - group buy?
 

Splendid, thanks for being patient with me :)

..plus you're going to need a new gasket for the generator cover when you come to fit it (just ordered an OEM one myself at a cost of £23), plus engine oil, and probably an oil filter.


Thanks Mike by the way for answering Grim-Lock's queries, much better than doing the old Chinese Whispers by me taking it away and asking you and then posting back on here.

Is there any real benefit to this?

Re: Lightened flywheels - group buy?
 

That thread seems to be split more towards the mod but general consensus seems to be no real downsides apart from throttle control and running in gears you ordinarily did not with stock?

maybe i did not read deep enough though

Re: Lightened flywheels - group buy?
 

Gives the crank an easier life, certainly an advantage in a race engine

Re: Lightened flywheels - group buy?
 

And the rods, which apparently are the weak point in a curvy.

Yeah, you sure see those things being reported as failing on the regular haha

Just wondering what the point in spending money on the flywheel is, when you could put it towards making the bike actually faster in one of a few ways...advanced rider training (the bike's faster than you, most likely), better suspension, better tyres, better brakes...so on and so forth.

Just my pessimistic 2p worth ;)

Re: Lightened flywheels - group buy?
 

Well, i've already sorted the brakes and suspension on my build, but the advanced rider training was something i was intending to look into. But that means i'll have the training AND a lighter flywheel. Demi-god status maybe?

You'll be chasing down Rossi in no time!

You've got a GSXR front on your haven't you? Thought about getting the forks sorted by Maxton or K-Tech?

Re: Lightened flywheels - group buy?
 

Suzuki chose to fit the SV650 with a heavy flywheel assembly; made of the flywheel itself and the starter sprag bearing housing.

The Curvy has a very, very heavy flywheel. The Pointy slightly less heavy, but still not light.

Suzuki did this to make the bike novice friendly because the rotating flywheel assembly has massive inertia; so the bike is difficult to stall, easy to launch from a stand and reduces engine braking.

But this has several drawbacks;

It give the crank a very hard time, particularly at high rpm, because every time each cylinder fires the crank is trying to accelerate but the inertia of the flywheel assembly resists this and is trying to twist the crank. This can lead to...

It blunts the performance and character of the engine because the heavy flywheel assembly is slow to accelerate and slow to decelerate.

It slows the bikes ability to change angle of lean (roll) because you're trying to effectively move the axis of rotation of very heavy gyroscope.

It makes it easier to lock the back wheel of down shifts if you're a bit clumsy with the clutch and revs.

Re: Lightened flywheels - group buy?
 

I've had the forks rebuilt with ohlins springs, i'll see how i fare with them, not expecting to be pushing any limits any time soon

I may be interested in doing this - when would you need the flywheel? Bike is down in Spain at the moment, hopefully back about 10 April.

I believe 650 means to suggest getting the spring rates and all else set for you and your riding preference

Front and rear have been sprung for my weight

I meant more revalving the forks, I can't even tell you the difference it makes to any fork setup. My VFR750 has standard, non adjustable forks that were revalved for my weight and riding style. I've not ridden any other bike (and I've owned/ridden a fair few, believe me) that handles as nicely, it is quite literally on rails. You think were you want it to go and it just does it with no hiccups. Best money I ever spent on a bike.

I'm seriously contemplating having it done to the GSXR1000 forks I've bought, but as they cost me a fair whack...I'm thinking I'll put it off until next year and make do with them as-is at the moment. I've asked Maxton for a quote so I can update this here once they they get back to me.

Anyway, completely off topic - nasty looking pic up there!

Re: Lightened flywheels - group buy?
 

Just dragging this back on topic!!


So far, interest is;


me - Biker_kev
Grim-Lock - assuming he can source a spare flywheel
Sheepshagger
DS77 - maybe?


Anyone else interested?

Re: Lightened flywheels - group buy?
 

We need 5 people to be interested for this to be worth it as far as Millemille is concerned. As far as I'm concerned I'd like to get this done asap, as I'm prepping my bike for the season, and I already have an offset woodruff key to fit, and an oil change to do, so thought I'd do them all at the same time, and I was hoping to get the bike back on the road for early April. I'm happy to hang on till the 2nd week in April though if you decide you definitely want to go ahead, and anyway there will be a 2 week lead time from sending off your flywheel.


Of course, if we don't get 5 definite yesses this may well be subjective!

Re: Lightened flywheels - group buy?
 

I'm in, just waiting for delivery of the assembly

Re: Lightened flywheels - group buy?
 

I'll try and find out tomorrow when my bike is likely to be back and let you know asap

Is it a simple job to get the bits off - are there any special tools required? Bike is an 08 pointy.

Re: Lightened flywheels - group buy?
 

Only the big bolt to remove the flywheel itself, everything else is normal sockets

If you're careful you can remove the cover without damaging the gasket.

Re: Lightened flywheels - group buy?
 

Cheers, do you know what size the big flywheel bolt is? My Haynes manual is down in Spain too!

I'm hoping to be doing brands on 24th April so will see if the dates will work.

Re: Lightened flywheels - group buy?
 

I may have 1 customer on another forum, I'll find out shortly. If they want to go ahead then the 4 you've got are enough...

Re: Lightened flywheels - group buy?
 

I have a spare one

Re: Lightened flywheels - group buy?
 

Assembly arrived and seems to be in good knick

Hi guys, i've just checked the spare F/W i have and 2 of the magnets are loose :(

Is this something that can be addressed with epoxy or similar, or is it fubar?

Re: Lightened flywheels - group buy?
 

There are reports of magnets being glued back in with 2-pack epoxy. Me? Given the consequences of a magnet coming adrift when the engines at full chat I'd not risk it.

Are the loose magnets next to each other?

Re: Lightened flywheels - group buy?
 

Yes, typically.
