compufire question

[Guest]

The various threads and the input of my mechanic have me very confused on the compufire RR install. I have a 78 gs1000E.

I took the compufire unit to a mechanic and gave him the appropriate write up links and asked him to install it while he was doing a valve job. He returned it saying my bike has a 2 phase system and the compufire is a 3 phase so it wont work.

I am under the impression that he is either incorrect or at the very least the compufire unit is supposed to correct a poor design from suzuki and I should go ahead and install the unit.

Is there something I am missing?


thanks

You're just missing a thinking mechanic! Your old bike likely has a seperate rectifier and regulator- your mechanic just saw the regulator (with two wires) and was stymied. The compufire replaces both the regulator AND the rectifier.
P.S. I'd probably check his valve work

I agree, you are missing a good mechanic.

Is the "valve job" that his is doing a complete rehab of the cylinder head or just an adjustment?
Either way, I would also question his work.

Your not missing anything. Your bike has a 3 phase charging system.

thanks guys.

that is what I thought. He was recommended to me by a few people who have older bikes. He was doing an adjustment and a few other minor things I didnt want to mess with. I got it back in worse shape that when I took it to him. Lesson learned.

Find a new mechanic.

It's critical to rewire the charging system if you want the bike to be reliable. The stator must be wired directly into the R/R, bypassing the factory harness. Make sure the R/R is grounded to a solid frame point or the battery. Not to the electrical panel or battery box. Lastly, the R/R power output circuit, feeding into the fuse box, must be checked for resistance build up in the connector terminals and cleaned appropriately. All this is critical and must not be deviated.

Good luck

Don't wait until the valves burn up to recheck them.
