I think you would be better of checking the ignition pick-up located on the right side engine cover. you may want consider searching for info on the ignition pickup, as apparently it is a weak link on these engines. That was the first thing i repalced when i got got mine as it had sat for a while.

If you did not completely disassemble the carb and remove all jets/emulsion tubes/needle valves then you did not clean the carb adequately. You could try adding either Seafoam, the Yamaha CARB-CL-EAN-ER, or Techron fuel system cleaner in an auxiliary gas tank and running the engine for a short while to ensure the mix gets into all the nooks and crannies. Let it sit for a couple hours to do the work, then drain out the float bowl, hook up the bike's gas tank and see what happens. Otherwise you need to remove, strip, clean, reassemble, and reinstall the carb.

SOURCE: how to drain fuel from carb bowl?????

there should be a screw or a larg looking bolt on the bottom of the float bowl (carb) remove it and it will drain use a rag to catch it and drain your tank add fresh gas (if it dose'nt run right you may have to clean the carb)

You can fail emissions on a bike in arizona ? Wow i thought california was bad....anyhoo let's get to your concerns....All those srews should be very close to the same setting....rule of thumb is start at 1and1/2 turns out on each screw, almost any gasoline engine will run at these setting then you can fine tune from there.....no wonder you had bad idling problems...Good luck to you friend....Tim

it is possible that th eplugs might be fouled but it seems unlikely after only two weeks running-my fzr would foul plugs but it usually takes months not weeks-also the engine would start but run on2 or 3 cyls. I found using one heat range hotter than standard plugs helped,esp. around town you seem to have been fairly methodical on your troubleshooting-if you have fuel and spark the next thing to check is comp. -if the plugs are wet it is likely fuel not oil-when I first bought mine it had sat over winter and would not start -it turned out that the valve clearances had closed up enough that it was low on comp. when ridden frequently it was ok but as soon as the oil had drained off the cyl walls it would not start-squirting oil in the cyls. would get it started but I pulled the cams and set valves to solve problem-starts ok now but I don't use the choke-you could lift the cover and check your valve clearances -it would be a good idea on a bike that you just bought-don't give up -be methodical and check one thing at a time-when you get it going it will be worht it
