Yip me andSully 60 might be doing something we just in the middle of discussion

So any wanna find me a bucket i can buy?

The results are in hot off the press people.

I suspect Mr Speedpro may have done this before see the graph below for results.

The red line was basically where we started and we ended up with the blue line. The two lighter more spaced out dotty lines are the torque with values on the right, these are really big numbers for a 140 twin but remember there's no correction for the low gearing.

We did a total of about 30 runs all up, these graphs best represent what we achieved. Although this doesnt have the very first run on it, the 15.2 number came up first, and most often over all the runs, so well done speedpro.

So we didn't really make any big numbers (thanks though slingshot, oh and sketchy, you know I need more than 13 hp to haul me and the ledsled around that Slipway) The different runs produced some interesting numbers one run we managed 15.7 right at the top like the red line but higher at the end. Another run which was more like the blue line ran to 15 at the bump at about nine grand and waved around 15 all the way to the drop off about 11500. Both of these runs were the run before or after the consistant runs like the graph without any changes made. So it pays to be a little careful with how you interperet the figures.

Rode it up the street for a we test run and race launched it and boy it feels phat now!

But there's a long way to go as I have only just started to develop this engine.
Stay "tuned" for regular updates.

Ive got a few bits n pieces we could cobble something together. You might have to fight Ivan for a twin motor, it would require a lot of work though, just the thing a young man like you needs!

Aparently there's some interesting R&D involving high tech gp chassis technology going on in the quiet rural environs of the South Wairarapa. The shoehorn may be getting dusted off for some serious cubic inches in the engine department and the quiet country lanes will reverberate with the roar of a high revving parallel twin. Rumor has it there may be a challenge ready for the 2010 SCS bucket Championship with a view to making it down to the BoBTT in 2012.

Watch this space. But don't hold your breath.

Sounds like fun

.
Although i dont have a great deal of knowledge but theres always time to start learning

Why didn't you buy TeamCudbys one? http://www.kiwibiker.co.nz/forums/sh...ad.php?t=55696

Lol the shoehorn had developed a good engine and was all in until you came along with another idea,

Now Im just waiting for a response from you young man

I sold a FZR250 ignition to a mate who fitted it to his 125T. It immediately went from 12hp to 16hp so it was $50 well spent. All you need to trigger it is a little round thing bolted to the crank with a little sticky-outy bit, you need to take off the alternator rotor, and a little bracket to hold the trigger coil close to where the sticky-outy bit goes round, hook up a few wires to coils and battery. It was a while ago so I can't remember the exact details but we made absolutely no other changes but gained 4hp, plus it revved cleanly to whatever the mechanical bits would handle.

Lucky guess with the hp by the way.

Faster than a standard CB125T !

Anyone know how much and what weight fork oil I should be using?

You really need the specs from the workshop manual and start from there.

The factory "setting" of forks for bikes like these aren't really cut out for the hard braking and cornering forces encountered in the swirling competitive world bucket racing.

But really with forks like that try 15 weight and start with something like a 125mm air gap (this is the distance between the oil and the top of the fork stanchion with the spring out and the slider at the top of its travel). The actual volume doesn't really matter just use this as a place to start and add or remove oil to make changes to suit .Making the gap smaller by adding oil will slow down the compression damping and conversly taking oil out will allow the forks to compress faster.
This is a simple but effective (read: cheap) way of tuning basic forks like those to some degree.

**Skunk** · 18th October 2007, 21:55

I've had different advice... 5 weight and 105mm above the damper rod with the spring out. But I'd follow advise Sully's in this case.

Anyway - as he says: set it to a known value and work from there.

Would this be based on your forks with the emulators?

The thin oil works in this set up with the enlarged damper rod holes at the bottom and all the control done through the emulator shims. Forks like Slingshots rely on these holes being small but this offers limited control. Thicker oil will slow the rate the oil flows through these holes.

BTW: Slingshot have you sorted out seals yet?

**Ivan** · 19th October 2007, 11:24

Would anyone mind if I come over If im not going to the trackday to the bucket building session?

Ill bring my boy Race car and hopefully fit a GP chassis in the back?

If its ok,

Ill let you know ok.

I was thinking I might leave the fork seals alone at the moment, I think the issue is probably with the volume and weight of oil so might try and get that sussed first...plus I've now only got a week to get it sorted and back together.
