100 cc motorized bike slow

Just to emphasize my point...


Now, like most people here, I rarely ever look at the side of the post to look at the location. My entire focus is on the text of the conversation itself. You can't blame us for automatically thinking in our own native measures.

WHAT???, your NOT an all knowing and all seeing mind reader extraordinaire???...lol...lol...How you disappoint me...lol...lol.

My engine has 150 of compression.

150psi - normal.
150 Torr - most of the combustion chamber is gone. (2.9psi)
150kpa - rings just stopped existing (21.7psi)
150bar - entire engine just vaporized (2,175.57psi)

Not trying to prove a point, but I am...

I am just more naturally talented at it, I reckon. You didn't seem to notice that I was also being wise ass.

I just know that your jet lagged, tired, having allergy attacks where your at right now in Texas, etc. etc. etc.

ok i think i found the problem just went on a ride today i was good for 15 minutes while riding and when i got back on it, full throttles good for 4 seconds then the motor starts popping and i saw smoke coming out of the intake or close to it do u know how to fix it it might be the fuel or maybe i put to much oil lmk

...as a good place to start check for an air leak. Spray carb cleaner or starter fluid around the intake manifold and where the carb attaches. Also like I mentioned before your carb may need adjustment. Sounds like it's probably rich.

That's because that particular pipe, the F2 Thrust, is just a piece of funny shaped pipe and not an actual expansion chamber. The MZ65 is an actual expansion chamber, but isn't really optimal for these engines, but somewhat close so it still works decently. Nothing will beat a properly designed pipe for the exact engine, but people either lack the skill to make them or don't want to spend hundreds to have somebody else make it for them.

There are a few other off the shelf pipes that are pretty decent with a little modification/welding. The Jog pipe being a very popular option.

Can you tell me more about these jog pipes?

Can you tell me more about these jog pipes?

It's a pipe for a Yamaha Jog 50. People buy them and modify them to work with their engine at the head flange side so that it bolts on and fits on their bike.

This is a typical example of what people start with. https://www.amazon.com/Performance-...732686878&sprefix=Jog+50cc+exh,aps,138&sr=8-3

If you need more detailed information you will want to do some searching. I have never run one personally.

Dude, I was just looking at that one! I was considering an mz65 but the power curve I've heard of is pretty nasty and only picks up at higher rpm. For my style of riding I think I'll need something different maybe with more low end gains. I've heard these jog pipes improve all around or at least mid to high. Thinking about buying one off amazon.
