If the light does not come on in N then you have a wiring problem or the bulb has blown. Have you tried changing the spark plug and checked the fuel filters are not clogged up inside the tank. take the fuel tap off (2 screws) and check the filters.

fosdyke Posted July 21, 2007 Share Posted July 21, 2007 Ok you know the drill - its those 3 things 1. Spark 2. Fuel 3. Compression If you've got all of these it should run (unless your timings miles out!!) If you are new to bike mechanics but reasonably handy try this website http://www.dansmc.com/ You don't have to agree with the guy's political sympathies but his 'online course' is simple and methodical - it's got some of my bikes going just through a process of logical progression. Good luck Link to comment Share on other sites More sharing options...
stephe51 Posted December 3, 2007 Share Posted December 3, 2007 I've posted this same reply in another thread. However, for tyonek's sake, I'll do it again. I think it's flooded. It happened to me so many, many times without me knowing the cause. It happened always when I let the bike tilt on its stand. The carburetor overflows and floods the engine. When I let the bike stand by the wall and is almost upright, it does not happen. What I did was I adjusted the float and it never happened again even if I let the bike stand on its own and the tilt is great. To make sure that it doesn't really happen again, I installed a new fuel switch and I switch off the fuel line when I let the bike stand. Link to comment Share on other sites More sharing options...
