I have had my bike Dnyo 4 times because mods done to the Eng and its more then just getting alittle more hp it also makes sure your air fuel ratio from idle to wide open is 6,000 rpm is correct so there are no lean or rich problems .Also if the person doing the Dnyo knows what he is doing it can be done in 3 to 4 runs to 6,000 rpm . Its just my 2 cents
I would be curious to know what mods you did that required the bike to be re tuned again four times. Can you post the figures you got from the retuning each time.
I will try to find all the info on each dyno test. The first was just slip ons and air cleaner adding a power commander . The second dyno is having the heads done by a speed shop .The third dyno is adding high compression pistons 9 to1 went to 10 to 1 .The fourth was adding cams .I know the last dyno the readings were 89 hp and 92 torque and when my bike had the first dyno it was 63 hp 67 torque .I will look for the other test and post them .
