Engine 4 Strokes at Cruise

[KCvale]

Well, it's your bike, jet it all you want, but that crap exhaust you have will still be there wasting fuel and power.

KC's right about the megaphone pipe not working good on a cg. I actually like the stock mufflers since the engine runs ok and is very quiet, but I'm not digging for extra hp out of the little thing, just enough to cruise easy at 25, top out at 30+. It's perfect for that just how it is.
Light weight, too. and Free. Hard to beat.

Hay Randall. You actually did tell us you were only running that pipe for now in your first thread. Surely no harm in experimenting. That's what I'm doing.

Well it has LOTS of power when it's not 4 stroking. I wish I had a Go-pro camera mounted on my helmet
to show you and others how it does going UP my gravel hill driveway and the flats.
The "crap" exhaust is only temporary any way. Thinking seriously about getting Jaguars CDI.

To fix a four stroking problem:

• Clean your air filter to remove any blockage - this may solve your problem.
• If you've cleaned your air filter, and you're still four stroking, you will need to put a smaller main jet in your carburetor.

Jag's cdi's work real good. I have 2 of them. With the cdi and a good expansion chamber you might not need to mess with the carby.

Yeah, I will keep tinkering with it. Noob learning curve. If it needs an expansion chamber, so be it:

Since you have a welder you should try making jags pipe! I made one (not exactly to jags spec) and it made a world of difference , recently I swapped back to a stock pipe while I was adding a belly stinger to my "jag" pipe and it was total crap , engine ran terrible with no torque.

Okay, I will take a look at it, thanks.

The other thing is as far as the noise goes, in my little town, most auto drivers don't pay attention driving around and will pull out right in front of you. I have found the louder you are the more they will notice you. It'so bad here that I even had a US Postal delivery truck blow my school bus stop sign the other day. My bus has an air horn that works VERY well.
