When You Fransesco come to Finland with Your 907 and i check it, then maybe You have very long lesson about those "naughty words"... :funny: :funny: :funny: Ok, that was only joking... i know, U keep Your bike as clean, as i do! (at least near...) :laugh: :laugh: :laugh: PERKELE!

I will come in Finland, Antti, but by plane

I'm using my 907 only to take a few short ride :funny: :funny: :funny: :funny: :funny:
No matter, I clean, oil, cuddle it....
Ciao

U are not welcome WITHOUT 907IE to Finland !!! I have visited many times in Italy with my Pasos and U dont come to Finland with 907????? Is that fair???? NOOOOOOO...... Btw, IF U COME WITH 907IE, then we have plenty of FUN here with driving around thousands of lakes together in twisty / good surface roads!!!! U need ONLY to follow me!

Do You want to feel heat of Fin Sauna and taste of Koskenkorva after that "very wet race" ??? HA!!! If so, then You are welcome here! :funny: :funny: :funny:

Ok, ok!
I'll come with the 907.
But, don't you want bring me on thousand frozen lakes with the snow tyres :rant: :rant: :rant: :rant: ? I've learned to ski only last year :funny: :funny: :funny: :funny: :funny: :funny: .
I'm a man of the sea!!! Mediterranean....
Really, I want to feel the heat of Fin Sauna and taste the Koskenkorva :lick: :lick: :lick: :lick: :lick: if I'll be still alive after a "very wet race".

No matter, You are always welcome here in Rome to enjoy the Italian way of life.

Ciao

Maybee this helps, from and older topic:

Before fitting the 150's Reyer fitted the 140 with 750 Monster settings (found on the internet). With CO measurement equipement making the best setting.
Them Reyer took the Paso to a dynorun

With tis as a result:

Reyer thinks the engine still run to lean. So he will put back the 150 jets and tries to solve this. 65 HP on the backwheel must bee possible.

Nice to see 750 Paso dynorun charts

, but WHY Km/h down, NOT RPMs ????

All i have seen, have RPMs down, not speed... What, if sprockets have been changed? It would be nice to see, in what RPMs U can get best torque/power... and in what RPM area engine function best.... etc....

Antti

Unless you are measuring at the crank surely you will still have the effect of sprocket changes ?

Rpm can be worked out though if we know the final drive ratio

In the UK nearly every tuning place will dyno in fourth gear unless asked otherwise or to do an "In gear" run.

Why they run in fourth gear I don't know - perhaps for ram air bikes this gives the best "average map" and for some bikes like TL1000's it avoids the artificial timing retard but for carb bikes why fourth gear ?

If they show MPH/KPH it usually means that they didn't have a place to hook up the sensor for RPM or they just didn't do it. In my area you can get an el-cheapo dyno run like this for 10 bucks. Very little set up but not much useful information.

They use 4th gear so that the engine has a nice long pull for the dyno to measure.

That's an inertia dyno so I'll take a couple guesses at some of the questions asked:

Plotting the output vs mph saves them from instrumenting the bike or having to get any data from it, such as gearing or tire diameter. Note that knowing the final drive ratio isn't enough to know what the corresponding rpm would be. Take that, measure the tire diameter, and you've still missed the tranny's gear ratios and the primary drive ratio.

MPH can be taken from the speed of the roller - that way all instrumentation is on the dyno itself so there is no added set up time or complications getting a tach to work (accurately) on different vehicles.

They might run it in fourth gear to keep the rear wheel from spinning under power. In any case running it in fourth gear makes it a little less violent of a test. In 4th they aren't going to spin the roller to 200mph nor are they going to go from idle to redline in half a second.

EDIT: Yeah, what he said. I guess I type too slow! :laugh:

Your answer must be better, you used 2 times as many words!!

Great minds must think alike!

I think they pushed it to the limit: 10.000 rpm. So 100 km/h = 10.000 rpm.
The bike runs better now with 150 jets. But still there is a gap around 4000 rpm. In the city it runs supergood, better then my Palls Monster. We still need to finetune it for the highway. But the nice weather is gone here. So maybee that will bee next spring.
Jon, the cost were € 30 thats around 35 dollars
