570 injector malfunction woes.
So Ive been having some trouble with my bike for a while. I managed to track the problem to the injector because as soon as I took the injector out it ran good for like ten minutes and then back to mrs grumpy, second time it was out I had it professionally cleaned, but same result, ran ok for ten minutes.
Symptoms would be it takes a dozen revolutions for it to start warm (anything but stone cold), bogs on low revs and engine sound slightly cracked up (lean condition). I hooked the lambda up and it would start at ok AFR but in a minute or so it would gradually go leaner and leaner. So its not clogged it just wont deliver fuel as it should.
Today I fitted a brand new injector and now it runs well all the time
*sigh of releif*
Just a heads up.
Edit: I also replaced the male fuel connector with the equivalent KTM part (77707010000) that has a filter in the connector, this part fits the OEM female.
Im going to fit a golan filter eventually, this was the quick fix and I like the idea that the filter is easily accessible.
