RPMs increase and decrease with blinker?

[Kentman7]

It was a bad voltage regulator!

*@%^$*@%^$*@%^$*@%^$ing Christ.

I switched the voltage regulator to a new one and it solve all the problems on this thread. Even the supposed “carb problems”.

the bike is idling and throttling great now!

Great Kentman, Glad you're up and going and pretty sure if any of us confront these problems in future, we'll remember what you've shared with us... Congrats and thanks... Though I still don't see how spark has anything to do with raising rpm,

I’m hesitant, but I’ll ask before anyone else does. What new voltage regulator did you use?

Luckily, when I purchased the bike, the previous owner had an extra one laying around and gave it to me. It was in the bag with the tile and registration.

Looking forward to seeing your results.

Is the charging system all stock still? Maybe any load on the electrical system causes the voltage regulator to let too much current through overloading the system. It is common for the regulatorsto fail, but usually results in a cooked stator and overcharged battery, not what you're describing.

You were right!

thank you for your help.

I really appreciate everyone’s help in this issue. Thank you all!

Kentman,
Good to hear you figured it out.

That's great, Kentman, how weird though. Like Rich asked, which regulator did you use? There are a few that will work, some (or one in particular), are better than others.

So glad you got it running!!

So basically what was happening is the voltage regulator was not working. Yes. But why were the RPMs going up every time I engaged and electrical system on the bike?

I think what was happening was when I tried to throttle up the bike, the coils and spark plugs weren’t receiving enough voltage to increase the RPMs. But, at the same time, the bike was still getting adequate fuel and air through the carb.

When I engaged the brakes or the blinkers the voltage would increase to my coils and spark plugs and cause RPMs to increase and the engine to rev up ( or in case of the blinkers, rev up and down).

But it wasn’t just the coils and spark plugs receiving the extra voltage that increased my RPMs, it was also because my carb throttle valves were adjusted to idle in high RPMs.

so, when the voltage increased, the system had enough fuel and air mixture to increase the RPMs.

does that make sense?

You need a bigger explosion in the cyl. to make the piston go down faster, to increase the rpm. I've always thought all the spark does is ignite the fuel, once the fuel is ignited, neither a weaker nor stronger spark would affect the speed nor power of the combustion of the fuel air mixture... Heck, you could put 5 spark plugs in a cyl. to ignite the fuel but I don't think it would affect the speed nor power of the combustion... Kind'f like putting 4 blasting caps in a stick of dynamite, the explosion would be the exact same as when using only one.

?

That’s where I was trying to go, especially when I noticed that the R/R and the ignitor shared the same ground.
