Actually, carburetor syncronizationproblems can cause a knock in the motor like the one you describe.
What's going on with those motors...it's really hard to tell. 24 years and how many owners?
Have you looked at the front of the engine to see if thereare pulse gens up there too?
Oh, and welcome to the forum.
Thank you so much for the welcome. I confess we've been lurking for a while. There's just soooooooo much wonderful information here.
Here's a bit of an update.
We figured the extra pulse generators dangling from the front of the motor in the '86 bike meant that the pulse generators were mounted in the back, like the other motor. Since my first post we have confirmed the motor on the bench that's going in the bike, truly is a 1984 motor.
After taking the timing covers off the motor in the '86 bike we find there already are pulse generators attached around the crankshaft. Interesting, because that means the wiring harness literally has two sets of pulse generators wired in. Both have the same length of wire, and both fit perfectly into position around the crank.
Bill, who's looking over my shoulder while I type, says he's wondering if one set is for the carburetor and one set is if the engine were fuel injected. It makes sense that Honda would make one universal wiring harness for both the carbureted Interstate and the fuel injected Aspencade. Am I making sense?
Thank you for the help and thoughts.
EDITED: Corrected from 1996 and 1994 to 1986 and 1984.
