How a "PowerBand" works on a 2 Stroke

[White trash]

Right-Oh n00bs, here's the skinny.

On your two stroke motorcycle, under the tank you'll find a dense little black cylinder, approx half the size of a red bull can screwed firmly to the frame by a couple of bolts. It will have a couple of little skinny coloured wires going in one end and a big thick one out the other end and going to your spark-plug.

This is the coil.

It does however, also contain the PowerBand which is why it's so dense if you remove it. The PowerBand is similar in its design to a golf ball. Essentially, there is one of those really thick rubber bands wound up tight as all hell in there. This rubber band if removed and stretched out would be about 30 feet long so leave it in there. You can, however, make noticeable changes to your 2 strokes power by fitting the PowerBand from another model. Suzuki A50 PowerBands fitted to my VJ21 RGV250 made it wheelie off the throttle in 3rd gear easily. I also removed the mufflers to aide performance and you can easily spin the wheel out of turn 1 at Manfeild once this has been done.

Hope this helps in your "Google Quest" for PowerBand info retard.

[Latte]

The A50 had the red powerbands right?

[White trash]

The A50 had the red powerbands right?

Mine were grey but maybe, yeah. It's worth mentioning that you need 2 A50s to get 2 powerbands. Unless you want to just replace the one RGV item for a little less savage power delivery. You need to add 1 HT lead to the A50 if you do this as the RGV only has one coil, 2 leads.

[onearmedbandit]

Will my powerband wear out over time? And if it does, could I just cut the outer shell off a golf ball and put the rubber banding inside in as a replacement? Should that be the case, could you recommend a suitable golf ball?

[Crasherfromwayback]

Should that be the case, could you recommend a suitable golf ball?

Yep...you'll want a 'balata' type golf ball for a nice soft powerband, or a top quility 'distance' ball for a hard hitting powerband that goes the extra few km's

Nice. Kiwi ingenuity at it's best again. We'll show the world!

...thanks for clearing that up for me....is their a way of shielding it from your body when it winds up... is it likely to make you ill if constantly used....when I first started racing it was two strokes...then I changed to four strokes...now its just constant whacking it all night....could this be a result of too much tension in my coils...

[yod]

I had the limited edition HRC powerband on my NS back in the day, so small you could barely see it......

it was teh awesome!

[rachprice]

Apparently I have to spread it first

[Ferkletastic]

Could I stick a 2 stroke powerband on my 4 stroke?

Would it then be a 6 stroke?

Cos I'm pretty sure that would be the coolest thing ever.

Actually harder than you may think. You have to fit a 2 stroke head to your 4 stroke to make a 6 stroke. Ask Shervin, I think he's doing the conversion on his ZX10........

Thinking about it further, I'm sure if you fitted a powerband backwards, the power would diminish with revs. I'm sure Honda do this on purpose in order for their buyers not to get scared of the potential when riding.

Wait wait wait, I'm getting confused. How many golf balls do I need?? Come on guys, I've got the cams out of the stinkwheel and my engine builder is waiting for me to get this sorted so we can decide between a peripheral port or a j-port. God damn, even google is no help. Wish I'd never opened this thread now.

You wanna be a bit carefull here Fraser. Add too many golf ball inners and you're powerband will be far too savage. Not being disrespectful but only holding on toone bar when that puppy kicks in could be disaterous. You've been warned big fella.....

We all used to think he was crazy, but now I understand him.

[Edbear]

Now I know where I've been going wrong all these years! You mean Golf balls! Here I've been mucking around with all these Goofballs! :facepalm:

[avgas]

Your full of shit.
Power band is the thing that holds your testicles together.
2-strokes have a very tight power band, so you can hang really big balls off them. As you get older your balls begin to shrivel up, so it is recommended that you change your bike to first a very peaky 4 stroke. This has a slightly wider power band, so you can flap you sack in the wind and feel young again.
Then when your balls are tiny you need a very wide power band - so you change to a Harley, a diesel or similar. The wide power band, and the small balls means you can tuck your nuts into your socks.
It is a good idea to ride in groups at this stage, as all your tiny balls add up to one big set - and you can scare off predators.

[schrodingers cat]

I hit my powerband the other day and it threw me off.
Is it possible to get 'beginner' or adjustable powerbands?:facepalm:

[Str8 Jacket]

I am more confused than ever now. I was told that you couldn't replace a power band after I broke the last one. I had to buy a whole new bloody bike!

Beware when fitting different powerbands....I used a YZ 80 one once and it was darn viscious. Darn near threw me off the back. Them ones are not to be messed with.

Take one golf ball as a bored child, go to your fathers extensively stocked workshop, place golf ball in vice, grab one of your fathers saws that isn't suited for the job, and cut the shell off the golf ball. Initially you will find lots of rubberbands, and after removing what seems like a mile or two rubber strips, you will find the bounciest ball in the world.

Oh how so many of my fathers golf balls would go missing.

If anyone is interested I have a set of new, old stock powerbands for an H2R Kawasaki 750. As you can imagine if you are aware of the legendary H2R powerband, these aren't small so won't suit sub 250cc bikes and may be a tight fit even in some bigger bikes.
At this stage looking to sell as a set, but may consider separating them if I can find buyers for all three.
Attached is a pic of the neighbours kid holding one so you can get an idea of size. Note that it is still in it's FedEx wrapping from when I purchased them (ex-TKA), all three still have intact wrapping and are ready to bolt on and go. Expressions of interest invited. Genuine buyers will be aware of the value of these hard to find parts. Be warned, these are not for the faint of heart.
Wrapping is signed by Kork Ballington, Greg Hansford, Murray Sayle and Neville Doyle and as such are collectors items in their own right.

To be honest I'm not sure, perhaps a question for a Kawasaki anorak type?

....if it were a 117A or close to that , it may just do...I was keen to go with the golf ball inner solution but it seems the waiting list for the top notch balls is ridiculously long,,,the only other option for high tech balls is on the black market and honestly, Im not keen on handling black balls...just waiting on a call from a kawakoozi boffin...let yer know...

[schrodingers cat]

It is commonly known that from time to time manufacturers stumble across the perfect mix and a batch is produced that is superior to anything else on the market.
When this happens the manufacturing mafia come knocking and the recipe is 'improved' to bring things back in line.
Think Castrol R. The old stuff was magical.

Anyway, this has happened with golf balls. A previous poster has been wise enough to preserve three and knows their worth. But. There is an untapped resourse.
Golf courses around the world have water hazards which are full of these old wonders. Naturally because they were so much better a light putt sent them streaking across the green and into the water - thereby driving up sales.

SO time to plan an assult on your local course. It will be cold. The older better balls will be down in the sludge and muck. It will be dangerous. You will need to dress in foolish clothing to blend in.

I however wish to offer the services of faithful Scuba Hound. Especially trained to sniff super balls even under water.
He costs 4 steaks and hour and my commision of a large bottle of Jack Daniels.

I've just failed my WOF , he measured 1.23 jigawatts on the powerband and states the legal limit is 1.21 (although he measured this inside the workshop which may have affected it), I'm told it's too peaky, and can probably get a wider, flatter one. Has anyone got a spare I can borrow, or should I stuff some steelo pads down there?

....pretty cool bit of thought gone in there ,BUT....if we are to lead the world in this technology, we need to sort out a system for balancing the balls to each specific POWERBAND requirement ...whether the manufacturers of the high end golf balls would agree to this stringency in their approach to regulating ball inspections in the workplace and ensuring a completely uniform ball left the assembly line is doubtful....it will in the end be left to the individual to decide upon which manufacturer they choose to go with....in the end the golf ball manufacturers tussle for track supremacy will probably end up with MotoGP being dominated by very small capacity TWO STROKES and a demise of the DUCATI marque as a serious bike manufacturer...
