I did see that. I wonder why they kept the fly-wheel.

Therefore the need to retain the charging system to keep a constant voltage to the electronics is imperative. With our conversion to fuel injection on the Gen 5.2 EFI, we have been searching for the lightest solution to this possible.

as for keeping the battery charged (if you go total loss)
we just plug in an optimate after every race.
we use a permanant lead, witht the plug coming out by the can hanger underneath, then you can easily plug it in without taking the seat off.
if you do a track day with, say for example 8, 15 min sessions (ive never done a track day so this is just a guess, just done acu practice days in the afternoons) if you take 2 fully charged batterys with you, you should be ok. As long as you dont leave it running for ages when its stationary, or using the starter motor for ages.
as i have had batterys be fine for 4, 20 min sessions and have juice left in em.

We've got a track and road NC35 and are taking the track bike on it's maiden outing at cadwell next month. The track bike is total loss and my plan is to swap the battery inbetween track and road RVF's mid day and bump it rather than use the starter. I'm hoping the battery should last.
I'm torn tbh between rebuilding the charging system and keeping it total loss.

I think a phone call to Mr Oliver or Chrisxr is in order tomorrow to see what's what.

I'm not convinced that there are big gains to be made from removing the flywheel altogether.
Would the reduction in crank inertia be a benefit for most riders?
I have a g-force gixxer kit waiting to go on, probably won't get around to it for a couple of months.

Hi,
I thought the ignition pickups were in the clutch cover? If they are and you run total loss ignition then i dont see why you cant remove it.
Cheers

Our race regs stipulate that the bikes must have a working charging system (hence the gixer flywheel/stator..), but I doubt you would see many total loss bikes if this wasn't a regulation.
Us Aussies are a practical sort... :D

Hello guys!
I run a total loss system on my RVF trackbike, and the batt is fine for 2 days in the track! I've used the bike to ride to the track and back 100km, and done 4 20min sessions each day, and the batt was just fine! I think you are over protecting with that!

CMSMJ1 , I know i-factory in Japan did a lighter version of the standard fly-wheel they also do an exchange service. It also seems that they machined the outside of the fly-wheel rather than the inside

they claim :RVF400 lightweight flywheel.
Price: Yen 29.400
(And processing only OK)
Extend the life of the crank, improved pickup
Suppose that's for the lightening only

IMO G-force is definitely the way to go
How much did you fork out all in for the G-force kit, parts etc ? I was a bit late to snatch one unfortunately

think I should

and see If they would make some more.

viper_biker, just to give you an idea this is the tools Royster is talking about found this a while back.

@ G-man - I have the Gsxr1000 flywheel in my road bike. It weighs feck all compared to the std one..
I will be removing the flywheel from the race bike this winter.
BTW - what is the weight on that rotor?
I am sure that I recall seeing 2 differing types in the NC30 anyways.
@ Xeno - I had a a faulty generator once and I got 20 miles out of the battery only.....can you share some more info on your setup?
