Airsal vs Alukit

Is there a difference in top speed with the 70cc Alukit reed kit vs the 70cc Airsal reed kit? Or are they both the same top speed? Treats was sold out of the Airsal kit so I ordered the Alukit reed kit

Re: Airsal vs Alukit

Apple to oranges...

Reeds vs PP.

Reeds setups offer better power bands.

PP is more simple all around.

Reeds you can get some great torque and speed out of after some modifications.

PP takes a little more finesse to get the same gains out of and require more specific clutch tuning.

I have owned plenty of PP kits and have been happy with them. With reeds there is just one more pieces of the puzzle to go wrong and cause problems.

It is really about preference between those examples.

Now if you were talking arisal vs polini, or Gila for reeds. Then it would be plini/gila

If you were talking alukit vs metra for PP. Then metra for sure.

Why are you bringing piston port into this, homie's asking about the difference between 2 reed kits

Thank you!

So ya the Alu isnt cast as well, its porting is decent but not as good, and most importantly the Alu has no boost port in the piston, long story short the Airsal is a superior kit

Re: Airsal vs Alukit

but OK, the airsal is 44mm vs the 45mm for the alukit.

if you get the 45mm alukit, it should have a window in the piston or maybe you got the sick hi-rev 1mm single ring piston, which i hear is pretty badass and chill.

so alright, i pulled the micrometer out and got a reading of 43.2mm from the top of the cylinder to the bottom of the exhaust port, that's pretty fucking chill for a kit thats supposed to have a 43mm stroke.

i got a reading of 28mm from the top of the cylinder to the top of the exhaust port giving EX timing 160º of duration.

This is pretty close to the 163º of duration that the airsal kit gives you, but with tighter clearances as far as setting squishband goes.

The 45mm alukit also looks to have a bigger exhaust port, width wise then the 44mm airsal kit, making it suitable for a bigger chamber.

I didn't bother measuring anything else because i didn't really want to. ¯\_(ツ)_/¯

So is the reed Alukit faster than the reed Airsal on top speed/rpms or nah?

Most likely , just like anything else , it simply depends on the tuner and rider .

Re: Airsal vs Alukit

so ok, here we go.

Max power RPM is a derivative of exhaust duration and exhaust tuned length.

Assuming you use the same tuned length exhaust with the airsal and the alukit, the airsal kit should rev out a little further on the stand or while actually rolling as long as the gearing isn't too high.

if the gearing is too high for the airsal kit to pull, the wider exhaust port and extra 1mm of displacement might allow the alukit to pull the higher gearing, resulting in what some might think is "higher top speed/rpms"

Ha I read "arisal" not "arisal reed kit". My fault.

Re: Airsal vs Alukit

Thomas Peffer /

Okay thanks a bunch. I appreciate it. So I'm putting a new piston and rings in the Airsal cylinder. The cylinder was in decent shape, only very minor scuffing that cleaned up good. It was the top piston ring had gotten stuck in the ring groove on the piston and was causing blow-by and gradual power loss due to an air leak at the reed block that has since been corrected. The air leak had caused the piston to get too hot causing the top ring to become stuck. Plus the piston had score marks along the sides possibly due to the resulting soft seize. New piston/rings are being installed. All should be good now. (edited)

Re: Airsal vs Alukit

♣Slew Foot♣ /

Same piston thing happened to me. After 3 seasons the ring was trapped by the mushrooming of the ringlands.

The heads matter I was running a modded puch 70cc

head. After I swapped it out for the Metra/hero Puch massive cooling fins for the win.
