working on a friends foreman 450 es, only the front tires were getting power? its solid shaft in the rear with shaft drive. so i started at the rear end, figured it might be that rear transfer...? all looked good, spacers, bearings, axle, all the splines.. so then im thinkin its in the motor, so since its shaft drive, the shaft goes through the swingarm, so i remove it to find bad swingarm pivot bearings, those were a b****. got em changed tho, and figured the power issue was still in the motor, except, i lifted the wheeler and started it, the output shaft spun, so im thinkin, well what about when its under a load, i put a 24" pipe wrench around the u-joint on the output shaft (so i dont screw up the spline), started it again, put it in gear, and all is great, awesome power comin out, even under a load... but when this machine was all together, pull it up to a tree, and only the front tires spin, no power at all to the rear end. im puttin it back together tomorrow, because i dont see a thing wrong with anything, theres power comin out the rear of the engine, driveshaft and splines are all great, bearings are good, rear transfer works properlly, and the final drive axle is good too with good splines everywhere, its all direct drive sh**.. i dont get it, im stumped, ill put it back together, if anyone has ANY idea what is actually up, pls reply, something electrical? no blinking on the dash, that i noticed, i've just been reading about all these codes n stuff for the foremans? also i signed up to hondaforeman dot com, and i cant even post on there, site sux far as im concerned.. i own a 00 440ex.... but i've been a small engine mechanic helping my uncle for over 10 yrs now and this is just retarded.. thanx in advance for any help.. sry for such a long post
