Got it in today. I love it do this mod.
No problem and took about 10 minutes to install dyna.
I have a dirt area I marked of that is level.
330' with gps and the results are.
With DG3 and key 54 mph@330
With Dyna and key 56 mph@330
Best top end was 66 with dg3 and 67 with dyna.
This is on dirt so there was wheel spin on all runs. I ran the dyna when cloudy and 84 degrees.
The dg3 it was clear and 72 degrees
Mods: tpi valve on air box
Mudlites 25" with tpi c series rims 5 lbs air on all.
Dg snorkel
stock jetting 138, 142
4 degree key
coolant, distilled water and water wetter.
Gas 91 octane with a little booster.
elevation 4,500 feet
rider weight 225 lbs.

Conclusion performance increase is noticeable. I think the greatest increase is in the mid power band.
The speeds are not that great but consider loose dirt elevation and rider weight. No exhaust mod or jetting mod.
The machine is running great, no knock or ping.
Bottom line a increase at 330 and slight increase at top end.

 

Thanks minimus, great post. People like you really help some of us looking for mods.

 

Yeah, 2mph is a good gain for the mod. I hope to try the cdi out in two weeks with my 4 degree key.
