Falclimber on the dyno (with link pipe mod)

nod Jay

the figures I quoted were aprilia's official figures

I would expect some degradation due to time / age etc

I would also expect some differences with different machines and dyno's

Any bike can wheelie easily, just needs technique.

Easiest bike I've had to wheelie was the GS1200, power output on that is 108bhp (IMSC), it weighs around 227Kg, and you only had to twitch the thottle to get the front wheel 2 or 3 foot off the road.
Personally I prefer the wheel on the ground makes for faster getaways.

Post of the thread...

All this virtual willy-waving does get a bit tedious, especially when most (if not all) of the figures quoted are wishful 'guesstimates'. The only hard numbers have been provided by Ben.

And dynos (as others have said) are notoriously variable. It's all down to correction factors, and how dyno operators apply them. The trouble is that not many people want accurate figures; most people are after bragging rights and aren't too fussed about how the numbers are arrived at, as long as they're big.

For me it's not the absolute values which matter. On my hillclimber it's comparative gains from my start point. If a mod doesn't increase torque or power, or decrease weight then it doesn't get fitted!

I've seen good gains with the rene airkit, link pipe mod and a skilled dyno operator spending a lot of time custom mapping a PCIII (the autotune tool on the dynojet does a pretty good job at achieving stoichometric but it's a good tuner who knows just when to dump a bit more fuel in, or take a bit out to get good throttle response that is worth his salt - and they're few and far between).

Both of my Falcos make about the same power with chip, airkit and cans (the *same* chip, airkit and cans transferred from bike to bike - yes, I have spent a LOT of time on the dyno with Falcos).

At the end of the day, I have 117bhp against the tuned big bore 1080cc TLs with 145bhp. Can still take it to them though. That may be more difficult at the more open tracks this year as one is now building a stroker big bore 1180cc motor which should punt out over 150bhp and a boat load of torque. Meh.

Come along to a couple of rounds this year and see the Falclimber take on all comers!

I'll post the dates up for those who are interested.

That was a cool thread grenade L-R-I threw in!

Pull pin, lob grenade, sit back and watch the carnage

How long do those big-bore TLs last, Ben? Are they still reliable, or prone to grenading? I bet not many of them still have the 'revolutionary' rotary shock absorber...

The 1080s are very reliable - easily do a season of racing with no rebuilds. In fact, one of them was stripped and checked over the winter and is good to go for another season.

The 1180 is a development engine my mate is building, so reliability is yet to be seen.

Rotary damper? Erm... no.

I had one out of the first shipment of TL1000S back in 1997. It was a top piece of kit, and the engine (certainly for the time) was a monster. The suspension (and to a lesser extent, the chassis) was a LONG way behind the quality of the engine, though. I'm glad that motor is still punching away in competition, although I'd prefer it to get beaten by a Falco...

Is it the S or the R engine that's being used by your competitors/mates?

BenWah · #39 Post by **BenWah** » Fri May 11, 2012 8:14 am

They use the S motors - they're lighter apparently. And they do go well.

Last year the Falclimber had them beaten and it'll still go well at the slightly tighter tracks but there are a a couple where brute horsepower comes into play (Shelsley Walsh, Gurston Down) which the Aprilia will struggle at - I guess I'll just have to ride harder than them. That's what I did last year, so don't see any reason to change the formula!

Good luck Ben!

must piss them off that the falco beats them....

9Obviously the rider has a major impact as well but!)

Yes, as Pete has pointed out, a well butt is probably a help .... though an unwell one may give extra incentive to reach the finish line quicker .......

.... and, indeed, well done - keep whooping those suzukis
