Ok, here is my 1 year old dyno run. I also have 2 other quads but i will save those for tomorrow.
We had to reduce the smoothing as the dyno was removing 2hp with it on. Dyno guy said normally you see less than .5 hp lost in smoothing at the most but when a spark plug gap is off you will see larger peaks and valleys. So, i guess i forgot to gap the plug. oops smile.gif


here yah go tim and john!!



Oh yeah, its also good to note my cam timing. I didn't know they were that far off but the exhuast was at 114 degrees. i don't know about the intake though. I only remembered to measure it after i had the intake off.

Oh come on Happyboy,you can do better than this.You had some grade school kid with parconsons draw this up. Just kidding it actually does exist. Sometimes the leads where it clamps on the wire vibrates agains the frame and causes this too.Nice afr can you say flaaat.

Except for the smoothness thats not a chart for you to be ashamed of. The cam timing and torque results are interesting. Why do the runs start at such high rpm ? You should go right off a rolling idle in as high a gear as possible to get the most accurate data.
