got the cylmer manual, did the trouble shooting and by process of elimination, the reason i am not getting any spark is because the ic igniter/ecu/cdi (part # 21119-1408) is dead. Team Mancuso powersports is asking $400+ for a new one; is there anywhere (in town, preferably) I can it for waaaaay cheaper?

Holy cow!

This thread is all over the place. Now I understand why people pay me so much to work on their carbs...... too much bad info out there.


Maybe you diagnosed it correctly but odds are against you on the cdi being the problem. Put it back together & try a short burst of carb cleaner or starting fluid into your airbox while its turning over. If it fires off & runs for a sec then your cdi, coil, & pick up coil are good & its a fuel problem and your're back to needing a carb clean. If it doesn't then you have to narrow down why you don't have spark.

Start with spark plugs, spark plug wires, then the pickup & coil. Work in order of expense. Not only are they cheaper to replace, the cheaper the part the more likely it is to fail.

Anything you put in the tank isn't going to do you any good. That's more of a maintenance thing than a repair solution. When bikes sit up its typically a combo problem of slightly fouled plugs combined with stale gas in the carbs. Sometims just getting the bike to fire for a sec with a shot of carb cleaner can clean it up & get it running. If not generally you should replace the plugs & you shouldn't need a very thorough carb cleaning (clogged pilot jets). Let me know what happens with that & I'll try to walk you through a little.

Not in the fuel line

You're going to spray it as an aerosol. either into the airbox or directly into the carbs if you have the airbox off while you're turning the engine over. This will take the place of the fuel/air mixture the engine is supposed to be getting if the carbs are working properly.

If the engine fires up, you will know the carbs are dirty & you're not getting fuel. Word of caution....A VERY BRIEF SPRAY is all you need. Less than a second worth. Its very flamable & can harm your engine if you abuse it.

You will hear the engine trying to combust when cranking the engine.


If that's the case, the ignition is confirmed good and you have a fuel issue. Drain the tank, clean the carbs. Otherwise you're trying to patch the real problem w detergants.

so you spent several hundred on a new cdi after getting advice not to?
The same money spent at a shop would've had you riding right now.

So what does a spark sound like anyway?

i checked the spark plugs today, they are fine. i put gas in it and tried to start it, one spark and that was it.

2 theories:

1) ignition coils might have been miswired (i checked those a long time ago)
2) pickup coil might be gone
