so i take m mc21 out today and it just seemed out o tune then when i get to 10000 rpm it flat lined straight away i thought dam power valves i only just adjusted them last week so thought i may have forgot to tighten the lock nuts but when i check them its all good so i then check the alignment marks and find the servo is not moving at all at any condition so i switch her off and move the servo by hand then start her up and the servo returns and starts working normal again all adjustment is still correct so i thrash it for most of the morning and it runs fine .
then after a quick feed and piss stop of about half hour i fire her up and as soon as i hit band in first i can tell the power valves are not working again.
has anyone seen this before or got any ideas why it would cut out intermitantly like that
cheers for the help _________________ "Batmans a scientist"
Have you left enough free-play in the powervalve cables?
It may just be they're adjusted too tightly and binding up.
I regularly lubricate the cables too. One of the cable oilers that you use an aerosol can with, works really well.
so after going over the cables twice i went to the electrics found the voltage to the servo would go from 12v to 6v every now and then and i could make it worse buy shaking the bike wiring so must have a short some were right?
so i check all the wiring no faults then i noticed it was doing the same thing with volt meter direct to battery removed battery and found it must have a short in one cell or something maybe one of the posts is corroded were it comes through the top case not sure but first time i seen one do this.
also when id pull up at lights with a blinker on it would cut out sometimes "thats fixed now to"
cheers for all the idea's
Im having the same problem right now too. I fired it up on Saturday after being garaged for about 5 mths. Seems the 'other dramas' that forced me to garage it have mysteriously gone, but the flat lining at 10k remained. It rides perfect up to 10k then has nothing. I need to go over the whole bike and check everything. If i find anything obvious, I'll give you a a shout. _________________ Winning isn't everything, but loosing isn't anything
