quicker response and more engine braking, I only cut the flywheel on mine like the American guys but its noticeable

The engine braking is a weird one. You don't notice it so much at lowers speeds but it's highly noticeable coming down from higher speeds, especially on motorway type roads.

it revs up quicker, but the main thing is that in midrange the thing takes off better. Be careful though as mine took some getting used too, i followed Lloydie but he lost me, now that I've got used to it, its great. Engine braking is better coming down the box at speed. Mine does occasionally stall after a fast deceleration though. Ive got used to it so give it a quick blip with the clutch in when rapid slowing down.
Its a great mod.

Flywheel all done to rogers specs and put back together , fired up first time as allways but the engine sounds a little different , and when revving it seems a bit more sprightly :) just got to test ride now and see how it goes :0)

Just been for a test ride and im amazed at how different my bike is after the flywheel mod , no lurching power , all smooth delivery and when your in around 6 7 8 grand the thing takes off , its awesome , its like a newbike , the engine braking is very mild in low revs but that makes the bike ride so much smoother , very impressed , thanks for all the help :)

Bit of an old thread but here goes.

This sounds like the type of mod I've got to try, just got my hands on a spare Varadero flywheel & will be having a go at lightening it myself with the use of a mates lathe, he has 3 & 4 jaw chucks so we should de able to do it.

How are you guys are holding the flywheel in the chuck? My first idea was to machine down a knackered crank for the taper & mount it :eh: for the perfect job, that way you can go nuts machining, as all faces/areas are accessible. Or has anyone done it by holding the bowl?

Holding it in the chuck with the bowl sounds the easiest TBH, & I like easy.

I plan on following lloydies method of just taking the disc down to 125mm by holding the bowl in the chuck :thumbup:

Also got my eye on a lorry bolt (Cheers Cybercarl, top tip) for the removal process & will grind a hex on the end so it fits my 1/2" Chicago pneumatic impact gun.

I had a listen to cybercarl's Firery Dyno Run vid :thumbup: I love/want that snappy reving @ 40 seconds in, how quick is that :beer:



Any help, do's & don'ts appreciated.

The only advice I can offer is, to make sure you don't get carried away and machine off the face of the flywheel, the bit with the timing marks on, leave that there as a lip,

Chris.

Sorry I can't help with the machining side as I have no idea. I can't take credit for the lorry bolt either. Mr Mon came up with that one many moons ago.

Hi carl,

Also sorry Mr Mon, flicking back'n forth on various threads confusion.. :oops:

On the YouTube clip I copied, what was the weight of the flywheel you were running? Love the throttle response.

Just to give me an idea what to expect once I get it machined :thumbup:

Extreme and experimental. They can be taken too far to point that it's no longer a benefit. I think Rogers specs stop at this point and any more taken off is kinda a waste.

See the following thread for more info. Lots of info in posts regarding lightning flywheels.
