Bucket update

[koba]

Use a large truck engine. Custom shaft running in ball bearings clamped in the last two main bearings in the block. Bolt the truck flywheel to a flange on the shaft. Use the standard truck clutch, bell housing and gearbox primary shaft. It's pretty much all done for you.

You do need to count rev's pretty accurately though, if you expect the sort of resolution likely to "see" the typically small improvements from minor tuning changes. Counting is easy, just a proximity or magnetic switch stolen from an automotive rev counter. Plotting the trend accurately is the tricky bit. That and the sprag clutch.

More info on the dyno idea...
I really like the idea aye but there are compelling arguments between either intertia or brake dynos..

I think a dyno would be the bestestest thing for making buckets go good.

That or getting Ivan to build them for you

Was it something to do with Ivan?

Only ever used a big water brake dyno, not familliar with bike-specific ones.

One advantage of the brake dynos is you can take steady state readings, you can hold an engine at a certain load/rev and mess with it. That's very handy when you're working with simple adjustment settings because you get data in real-time. The main disadvantage is that all brake dynos make heat, and that affects the load and has to be compensated for, our one had a table of offsets you needed to apply but less ancient ones correct automatically.

Inertial dynos like that flywheel concept would be easy enough to construct, but you'd have to take accurate data snapshots as it spins up. The larger the mass the longer it'd take, and the less accurate you'd have to be with timing. The only real downside seems to be it's inability to hold still while you mess with things.

No no ivan hasn't touched this bike. Ok he rode it up and down the street actually.

The powervalve actuator wasn't even connected to the powervalve's properly... Its something ivan would probably do tho!

Ahh, I do remember the manual saying to use loctite (or the suzuki official equivalent) on the grubscrew that locates the fork bit on that arm bit...

[Ivan]

Fuck off, I wouldnt even fuck round with powervalves and whats thatgot to do with buckets any way lol

Why not, they are extremely simple.

This wouldn't be the first time there was an post in this thread.

Has the next bucket meeting been confirmed?

[Ivan]

I ride 125's no powervalves in that sucker haha

Well since we getting offsubject I am going to have my 125 engine checked over and might even run a faster 125 at Puke if I am able to suss it out

[Skunk]

Finally got the 17" wheels on the bucket so we'll see how it handles at Taupo. Can't test it here as the fancy new disc for the brakes is waiting in Hawkes Bay for me.
Here's a computer rendition from the CAD file.

What you mean faster? Your one is fast as, faster than mine anyway. With you on it you wouldn't need a fast bike anyway. Going fast at puke is all about rider skill, something you have plenty of....

[Ivan]

Yeah my ones cool as and I love it and all that but,

My brother probly aint riding his 98 at Pukekohe and it got better suspension, Ported cases etc its awsoem myne is good it depends,

Most likely I will be on my 96 tho...


Should be fun

Het AJ,Remind Luke to bring my back protector to the next round of Welly buckets, I didn't remember till I was comming home. What happened to the 150 he was riding' the last I saw was him pushing it off track at Taupo?

Lukes bike seized. He has the back protector in the van.

Shame about your bike mate...
