Shit , how much better could it get Shocked
I went for my first solo squirt on the Rosso on Sunday . I'd ridden through town with Jan after the recommissioning - with the factory map , usual hiccups but not too bad. Uploaded roller mistral map a week ago and only got the chance for a ride first thing Sunday , What a different bike, I'm only comparing with the flat tappet engined GRiSO , but Goodness Me what a difference, just a slight crack of the throttle , it wants to pull my arms off. And you've improved it from there ???? WTF

Say goodbye to your arms. They will ripped out and flop uselessly to the ground with the new map.

Oh fuck! I'm riding down to the coast tomorrow and yes, I'll be putting this map in before I go.

Wish me luck.

Mark doesn't disappoint.

Oh yeah, the latest roller maps have a rev limit of 8750 RPM. If you end up with a rod up the chuff, or get done doing 250km/h, tough titties. cheers

OK Mark, that raises a question I raised some time back regarding the safe limit for these engines. If you remember correctly, mine is limited to 8400, and I asked at the time what a "theoretical" safe limit is.

Any clues, or are you plucking a number out of a darkened place?

3 reasons:

1. Roper hasn't blown his up yet.
2. I set 8750 on the roller maps when testing/building them so I could get better readings at 8500. I didn't blow mine up (yet).
3. Roper hasn't blown his up yet.

Since there hasn't been any issues, and since most riders don't visit 8500+ often, I left them there. My shift light is still set at 8500, so when riding for reasons other than map building, I'm inclined to shift just before the 'blurp blurp blurp' when the fuel cuts out.

They may even go to 9000 without issue.

I wouldn't do it on a flattie. A pushy like yours? Fuctifino. There's only one way to find out.

Cheers mate. Just as I thought - FIIK either. It's a moot point anyway as I'll leave mine where it is - just curious. 8400 is still not bad for a pushie, though

Pick Me cheers ,
also in the market for another Hi mistral pipe for the track bike build. Or do you think a different pipe might avail some more ponies ?
Tony , Are There any aftermarket push rods for your engine, titanium maybe, 9000 rpm easy Very Happy

Ron, I don't think 9k is too far off what it can do now. However, longevity is more important to me. When I was doing tuning runs, I had to go through the rev limiter to see what the AFR was - the old girl had no hesitation going through that limit, and I often saw 8500 in the logs - also showed no signs of running out of puff - just curious of what a theoretical limit is.

Obviously the factory does not have an issue with 8400 and they play if super safe.

The Carbon Hi-Pipe weighs less than 2kg, so it would be my pick. Chuck in the Arrow Ti headers and mid pipe. Pull the dBk to move the peak torque up the rev range and tweak the map a bit to get a few more ponies. Who cares about tractability, if you're gonna be spending all your time above 6K?

Now Ron, if you leave it looking close to road legal and store it at my place. Archerfield airport is 5 min from my front door. Fly one of your little hairy plains down in the morning and bring your rego plate with you. I could even bring you a hot coffee.
We can be on the Oxley before dark...........................

OK, not time to cover everything due to limited innerneck but brief spurt to 8,750 seems fine but I would hesitate to hang out there for more than a few seconds. While immensely strong the rods are quite heavy. There is a lot of mass flopping about in there even with the super-light *Modern* pistons. Add in the fact you're using beehive valve springs and you may end up snapping a spring if you poke the badger too hard.

Tony, for what it's worth my old 'Little Hotrod' I built in the early 90's used a 70mm crank with 4mm overlength Carilos. It had a shitload of other kit in it but it produced 84 RWHP @ 9,750 on a conservative dyno. That was indicated by the 'Vagueliar' tachometer mind so it probably cracked 10! The problem was that it ran its big ends regularly due to oil pump cavitation. While this is less likely to be a problem with a Gerotor type lil pump it's still a consideration.

The limiting factor with the 2V is always going to be valve and port size. Yours at a guess is making between 78-80 HP at the rear wheel. Getting more will be a matter of incremental improvement and the costs will mount up quickly and reliability WILL be compromised. In all honesty if you're happy with the mapping? I'd leave it alone. If you really want more? Buy a different bike.

Anyone want to go shares in a Tuono? Surprised

Pete

PS That was from 891cc.

Arrow Ti headers are on their way ( but I want them on the Rosso Viva la Fiesta )
So a mistral Carbon high pipe it is then, Does anyone have one kicking around ?????

Megaphone map updated. Interestingly, the Black-X and Megaphone will run great on either map.

Also released US versions. They have a tamer ignition curve, to prevent pinging with crap ethanol fuel.

They all have the 8750 RPM rev limit. Use at own risk.

Yep. Did it fit alright? I have a Ventura rack holder on so you may need a 2mm or so washer between the muffler bracket and the underside of the guard. Keen to hear your thoughts on the difference to hi and lo mount. Cheers.

Hey Beetle. Thanks for the work you do. A few months ago you sent me the Mistral High Pipe dbk map for US. If I recall you hadn't yet finished the non-dbk map. Now I see you have updated the map!

Can you please send me both the latest hi-pipe dbk and non-dbk US versions? I sent some money to contribute to these efforts - just let me know if you'd like more prior to sending out a new. Could not be happier with your maps. Excited to see what the new does.
