Thanks ,, it's been a fun project and the bike is a keeper.
Even thought the bikes are virtually identical in o.e.m design,
I prefer riding this bike over my 220. I'd say the suspension
settings are closer for our type of terrain. And the motor is so smooth with good power. :nod:

I'm always tinking or trying something new.

I made a reed valve spacer out of 1/8" aluminum and
it did make a difference that you could feel.

Was it night and day , NO , but added a little more bottom.

Just a little fine tuning as it shows how sensitive 2 strokes
really are.

HOW BOUT ALL THIS CHATTER ABOUT THE 2 STROKE COME
BACK !! nod: :) :nod:

The other thing we're doing is to stiffen the bike back up for a more aggressive riding style . The .35 fronts with a 4.6 rear gave the bike a good balance for a beginner rider but after riding my 220 which is fairly stiff , we're putting .37 front springs in along with the
factory 5.0 rear. Should be much better :cool:

I didn't realize how much this bike wallowed in the rough untill I put the stiffer springs in ,,,, what a difference. I also tightened up the dampening some. :nod:

I've settled on a 12/49 gearing for our type of riding , good responsive low end but too short legged.
