&%$#@!...in my post related to the dynos you guys are reading, i saw that most of you reached 42 and even more hp at the wheel. My bike was dynoed with cams, powerbomb, doma, high compression piston, modded jetting and one run with the airbox with the bafle removed and another run without the whole airbox cover. CAN SOMEONE TELL ME WHY i`m only seeing 38.5hp at the rear wheel??? The f"#&... dyno must be dead or something. That dyno belongs to a friend of mine, its a dynojet model 150. It can calculate the power available at the clutch (or is it at the crank ) by reading what its called "negative power". Now, the rear wheel hp and the negative power should be added togheter to reach for the engine hp. Why (according to this) does my engine reached 64 horses (wich are 3 more than a CR500r) and only 38.5 horses make it to the rear wheel??? Where are my 26.5 horses??? :D Wich seems to be the problem here?? Thanks.
