Bike Pulsing


Guest Anonymous

Recommended Posts

when tootling along through the gears my bike runs sweet as a nut.. but.. as soon as u het to higher speeds.. 90 plus.. my bike seems to start pulsing... like its starving itself of fuel... like there a load of clag causing a slight blockage


am thinking along the lines of either flushing carbs out... getting it re-dyno'd an checking jets, and or new fuel filter



anyone have any other suggestions..?

My FZR 400 did that a couple of weeks ago!!


Turns out one of the HT leads was loose and it only showed itself at higher speeds....

....worth a check!!!!


Good luck!!

 


Will have to have a nosey at that, :D

I thought I had a similar problem when I first got the Blade, it was fine accelerating but trying to hold a steady speed it was jerking like mad. It was because I was holding the throttle too tight and as the bike is so responsive, it was going on/ off the gas all the time. :lol:

take a look at the chain tension/condition


one of my bikes once did that and it turned out to be a tight spot in the chain


i adjusted the chain using the tight spot was a bit better but benifitted more from a new chain


might be worth a check

i'll be buying a new chain come the end of the month so should be an all round improvement there anyway..


i stripped the bike down last night.. checked all breather pipes.. HT leads cleaned air filter.. etc.. so need to take it out for a run this evening...


see how she performs...


n if need be.. dig out the haynes n eliminate every possibility..

Thinkin' of fixing my FZR4 and getting rid of it!!


Had enough of all the small things that go wrong with older bikes!!


Think I may have fallen' out of love with her a bit!!


Had her 5 years tho', so not bad for me!!
