Author Message   Kinder Posted on Friday, April 01, 2011 - 01:40 am:        K, it's late, I'm tired, I donated blood and my head is sore from trying to figure out why my CR pulled like a lame mule on a dyno today. Bike is due for new plugs (20000km) and sure it had fuel stabilizer in it and maybe the batt was weak but really? Would these things make that big a diff? barometer: 881 hpa Temp 22.2 according to my watch. Pull 1: 103.75 Pull 2: 103.77 Pull 3: 103.48 Correction factor: 1.13 Altitude: 1179m   Firemanjim Posted on Friday, April 01, 2011 - 01:49 am:        Ouch-what were the AFV's?   Kicka666 Posted on Friday, April 01, 2011 - 02:21 am:        On what type dyno, they all read differently.   Alex Posted on Friday, April 01, 2011 - 02:38 am:        Dyno probably measured in Kilowatt. Multiply by 1.36 If the bike feels really powerless while driving forget what Iīve written above.   03fatboy Posted on Friday, April 01, 2011 - 07:36 am:        And also if you look at 1179 meters altitude that is 3867 feet above sea level, that will rob you of a lot of HP. And even more so if it is humid and hot.   Kinder Posted on Friday, April 01, 2011 - 03:41 pm:        AFR's were spot on. Haven't ridden bike since new harness and stator were put in. Altitude should only affect things by 9-11%. But thats what correction factors are for right. Dyno jet dyno. No forward facing fans.

Bike wasn't strapped down in rear though. Would that make a diff?   Carbonbigfoot Posted on Friday, April 01, 2011 - 04:29 pm:        Oh, heck yeah. I bet you were spinning. R   Jules Posted on Monday, April 04, 2011 - 05:42 am:        Bike wasn't strapped down in rear though Any ideas why he didn't strap it down? When the operator was tying mine down i was almost scared he was going to snap the damn thing in half he was pulling so hard!   Alex Posted on Monday, April 04, 2011 - 07:52 am:        Itīs a 1125, not a 160cui dragster. If You have a good dyno You donīt need to strap it down. If You strap it down heavily You will loose power by deformation work of the tire.
