[QUOTE="DEANSFASTWAY, post: 640300, member: 31309"] Hi Rich , Hi Nestrick : I really hope this is not youre problem but it could be . If the intake and exhaust springs are swapped into the wrong places the longer springs could coil bind and cause valve noises and much much more parasitic mechanical drag than if they are properly installed and may drop and hit the piston.. The exhaust valve springs are about 10mms longer than the intake springs which are designed shorter since they sit under a bucket lifter assy. I think the stock intake springs have a white paint stripe on them and the exhausts have blue paint or something like that.If this is the case though you probably would have dropped a valve the first time you rode the bike . To be safe Id have someone in the know check it out further . Actually the first time I had one apart I mixed up the springs and didnt notice it until reassembly . Not to mock the guys at the Honda dealer because I know its hard to work on Goldwings and adjust valves on 929s 954s and stuff,those bigger four cyls have 16 valves and you can hardly see them let alone pull up the cams and swap shims, I know Ive been there. Well, maybe they just overlooked it Warranty work new bike preps and problems and stuff Id make sure If I were you my friend . You might just have a maladjusted decomp lever like others said though.You know almost every time I get involved with a tired CRF or one with tight valves the customer has already installed a new piston kit and usually doesnt understand the valve adjustment deal.Usually the last bike they owned they mixed gas and didnt have valves.With stiffer valve springs correctly installed there may be a hint more resistance to rotation but the amount would be negligible espescially on a single cyl ,I doubt anyone could ever feel it by hand maybe like turning with an inch pound torque wrench or something .But i bet if there were HD springs in the wrong spots it could cause a shakeup . Good Luck and let us know what you find out. DEAN [/QUOTE]
