Hi It nearly starts, then a very loud backfire. Does this indicate a timing problem? Many thanks Simon
your starting fuel enrichment device (choke) system could be clogged. drain the float bowls and try again. and how long since your last ride ??
Thank you for the replies 5th generation 1998. Things are getting worse, I have no fuel pump sound now when I switch the ignition on. I’ve checked the fuses around the battery area and all ok. Is there any other fuses anywhere?
With no fuel pump noise, that is the first place I would start. Doesn't matter what else works, but if the fuel pump no worky, then bike no runny. Get out the ol' multi-meter and check voltage at the pump.
