Heres my dyno, whats next to get it better?

So i got my aerox dyno'd and heres my graph...




As you can see im getting max power around about 9000rpm, but yet its still revving up past 10000rpm, the person who dyno'd my bike stopped at 45mph as the revs just kpt on creeeping up and he didn't want to blow it...

Since the bike was dyno'd i swapped my 4.1 gram rollers for 3 4.1 rollrs and 3 4.5 rollers, this helped a little but i still dont think its producing peak power and is still revving like mad past 45mph...

What can i do to help this get a lttle better ??

What i',m running...

Aerox 2003
Polini Sport 70cc
Hebo Performer Chrome Pipe
Standard carb(96 main jet)
Open Polini Air Filter
Standard clutch with polini springs
Top Racing Torque Spring
mix 4.1 and 4.5g rollers.
Polini Speed Control Variator And Polini Fan Pulley..
And i thinkkk thats it ...

 

i can't see it cratch:

 

me either

 

wasn't sure if i posted it correctly lol, heres a link to the graph...

crank and cdi mybe?

 

thing is i want to keep revs down, and power up.. max power is being made around about 9000rpm so theres no need for the revs to be much higher, and if imnot gona be going over 10000rpm, do you really think im goona need to upgrade crank? if i was to add a crank i would go for a new crank, cdi, primary gear-up and 19mm carb... but i was looking to tune my set up down to keep max power through out rather than go along the line of a high rev set up. not paticulary looking to splash out the money on the crank + fitting..

 

hmmm cratch: in that case im not sure mate

 

have you tryed heavier rollers like 4.5g - 5.0g?,,,

heavier roller will help to bring the rpm down

 

thing is the polini cast iron is a relatively low revving kit, its more a low to mid range
torque monster than a screamer....

I would say a 21mm carb would be the next logical step, and should fatten up your power curve...

i got a noticeable increase in performance when i changed my std carb for a 21mm, back in my old polini cast iron days :grin:

 

thanks for the replys, as soon as i go a tad heavier in rollers i get a nice big BOG about mid-range.. i also thought the polini kit wasn't a screamer, which is why im trying ot keep revs down and power up! i dont think the hebo performer pipe helps to much as it's producing peak power 9000rpm, but i didn't think that was TOOO high. i think i've got a 22mm lieing about, i'll give it ago n see what happens cheers guys... keep the ideas coming in..

 

thats exactly what i found on mine m8, i had a leo vince zx on my polini cast iron, and it went really well, considering....then i changed to a Laser x-pro, did a shit load of messing around setting it up, but i never thought it went as well as the zx cratch:

and we all know how crap everyone says the zx is :lol:

The morale of the story is, the cast iron suits a low revving pipe...

you could get your cast iron ported, to bring the timings in line with your pipe :grin:
just raising the exhaust port 1mm and opening out and matching the whole exhaust tract would do the trick

 

i'll give the 22mm a try and if not maybe look into getting the kit ported thanks for the help..

 

why dont you fit a gear up kit this will help you go higher speeds with less revs

 

Gear up kit and a 21mm carb with air filter

 

i got told too use half a gram heavier rollers and put a very thin spacer between fan pulley and the bellt on the variator, and i did so.. the revs dropped a little, and picked up alot quicker.. he told me to put the spacer in so the revs don't shoot up towards top speed, he only took my bike to 45mph as the revs shot up after 45.

ive now added a 22mm carb, and are considering a primary gear up kit, do i raise the chance of blowing the crank if i add a gear up?

 

yes, if i put lighter rollers in it does exactly the same just revs higher before dropping off the revs and dosn't make as much power! i have also tried using different clutch springs in the past and have found that the ones that came with my speed control kit have been best.. and for fueling i had this checked and it was fine, and also got my new carbs fueling checked.

i was just wondering as there will be a higher pressure on the crank as it has to turn over bigger gears rather than turning smaller gears at faster higher rpm and was worried that this will add more stress to the crank.
