engine cuts out with even the smallest use of throttle?
Posted: Sun Nov 13, 2016 1:04 pm
Hi guys, excellent forum you've got here!
Hoping somebody's gonna be able to shed some light on my issue, I'm assuming this is gonna be a carb problem but not 100% sure, I am a fairly new biker. Basically the bike starts (using the choke to get it started - it's getting quite chilly out..), and then runs smoothly with choke off. However when i touch the throttle (at all) the engine immediately dies? I've had the tank off to see whether the throttle cables are free & clear - they are.
Any ideas? Have done some reading and I'm thinking that when i open the throttle valve more air is getting in but not enough fuel? What can I adjust in the carbs to get more fuel in too?
Context of the issue is that I recently replaced the downpipes, the OEM ones were rusted to hell with holes in them, the new ones are stainless steel 'black widow' pipes, but they're pretty much the same pipes so I understand that if they're similar enough to the originals that a rejet isn't absolutely necessary to make the bike run?
Regardless, any help would be very much appreciated!
