  I wonder why your mileage is so different from mine. I only have 1000 miles on it
but generally get 70 - 80 mpg. It may depend on your commute...

  I noticed it is a bit cold blooded, will the waterpump mod allow it to heat up quicker
in the cold weather?

I'm on vacation with the family in sunny Vietnam and thought I might be able to purchase the
side body kit shown on Kymco's global site;

They work on the 50 125 and 200cc Yagers but here they don't show a Yager. Maybe
they renamed it for this market? So does anyone know which model might be a Yager?

I found a postcard for sale with Ms. Kymco's picture on it!

Hmm this guy is getting 60 MPH out of his 50cc, on my 170cc I only get 60 MPH
it just doesn't seem right...

 He's probably 50 lbs lighter, has 40 PSI in his tires, rides only downhill, uses non ethanol
gas, has an aerodynamic windshield and so on but still he should be slower than me on a 50.....

In looking around the interWebs I found this chart;


  It shows the length of the intake tract to tune for different RPM's. The tuned RPM can have
10% more flow so it's an easy way to give us a little boost. The stock length appears to be
around 22". It's a little tough to measure as it's the length from the intake valve to the bell
mouth in the airbox;


So it looks like we are tuned to 6500 RPM's which is where the torque peak is. If we wanted to
experiment with setting it higher we would need to shorten the intake pipe and put the new bell
mouth on the now shorter tube. This would necessitate an extension on the airbox to contain
the now shorter intake on the inside side of the air filter.


One problem is the bell mouth is glued to the airbox. The second is how to cover the new shorter
end into the airfilter box? Anyone up for some tuning?

I found this on a site today. It says Blade S4 Evolution muffler by M Factory for a King
180cc Kymco. I'm thinking it would work on the Yager. It talks about moving the oxygen
senser to the new headpipe. The most interesting thing is the dynochart;





53500 yen though, that sounds like a lot! ($650!) See the long headpipe? That tunes the muffler to higher
RPM's as is needed on a scooter. Most scooters have too short headpipes as the packaging is difficult.
