ignition question

[wadester]

Heres a question I feel stupid for even asking but,I know the firing order on a 107'',however its got a single coil dual fire setup for the ignition,is it possible to get the plug wires switched back wrong,or does it matter?

I noticed alot of popping goin on under steady throttle and the ignition coil is the only thing I've touched so,,

Yep, it matters. From the coil, front to front jug. Back to rear jug. If this is correct, ck the coil wiring. If this does not solve the popping, ck and/or replace the rubber caps on the carb. They dryrot n suck air.

HMAN has it right. Popping usually happens with a lean condition. Check for vacuum leaks at your intake and also check your exhaust pipes are tight. Clean out your carb bowl and go through these adjustments.

Actually, on a duel fire coil, it doesn't matter which wire goes where. Both plugs are firing at the same time.

I stand corrected. Thanks Shannon

Perhaps on a dual fire they do but on a duel fire one might be faster than the other -- after all that's how you win a duel! (as well as being a good shot).

Found that out as a kid. Buddy of mine, and I switched the plug wires on his brother's Harley, to mess with him. It fired right up and he rode away. Later we asked why, and he gave me my first motorcycle lesson.
