People 150 - no spark, new plug and boot assembly - any ideas?

Hi - we called the Kymco place, talked to a mechanic, and they suggested we do an online search for an answer (sometimes I wish we had bought a HONDA!!!)

Any ideas what the issue could be?

SORRY - this is what happens when the wife types out the message - it's a 150, not a 250 as it used to say in the subject line.

A bad attitude?

Seriously... could be the ignition coil, CDI or something else... in that order.

No doubt the attitude sucks at this point  - after a lot of frustration and nobody around who knows the machine! He's worked on bikes for a lot of years (wrenching makes him cranky but he still insists on doing it) and this one's got him stuck.

Thanks for the suggestions.

Well, the basics are spark, air and fuel -- if you have all three (in something approximating the proper amounts, at the right time), you have a running engine. If it's narrowed down to no spark, it's a process of elimination in the ignition chain, eh?  It shouldn't be too difficult to pin down, really. Check the ignition coil, first. If it's good, check the CDI, next.  One or the other will be the culprit in 98.7% of the cases, if you've ruled out a bad boot connector, already.

Thanks again - I'll let him know. He's got a  friend who's an airplane mechanic coming over tomorrow so I'm hoping it'll be resolved this weekend. The weather's way too nice not to get to use my scooter!
