It could all be in my head but I think the engine sounds louder. Not like an loose exhaust or anything. Just a little louder when riding.
If its not all in my head what could be the cause?
I've been thinking its the weather changes throwing the carb off
I ride it like its a getaway bike(After warm up of course)
No running problems just seems lightly louder all the way around. Not a specific section or part. No shaking or vibrating.

It's possible one of the baffles in the muffler broke off, this can allow more noise to make it's way out. However, if you are not experiencing any performance issues, I would treat it with the tried and true method of if it ain't broke, don't fix it!

It could also be the packing around the core is pretty burnt up they do not last forever.

is it a stocker? Look for soot on the rear wheel.... On my 10" scooter, the weld broke on the back side of the muffler and opened it up a little. Made the bike a little louder... worked fine until the muffler finally fell off.

one time i forgot to reattach the hose under the valve cover. it was very loud. check your exhaust and pair system hoses for any leaks.

So before going to work I inspected the cvt and found nothing wrong. Well the spring to the kick start broke but it still works.
I then checked the exhaust more thoroughly and noticed it was cracked at the mounting. (Its getting bad fast)
I have a plug designed to dissipate heat and its cold outside so its not overheating.
I'm not replacing this exhaust and i'm buying a pipe for the performance muffler I have in a month.
Can I just up jet to compensate? Haven't done a plug check to confirm a lean burn yet but i'm sure it is.
Also when I started the bike leaving work it was smoking like the rings were blown until it heated up.
Rings are more prone to blow at high rpm with a lean mixture right?
Oil was also black.

It does sound like you might have bad rings, though it's not definitive at this point. Lean conditions can cause all kinds of problems with the piston, rings, and valves. Only a plug chop can tell you for sure if it's lean, best hunches are never the answer. With 6g slider weights, you shouldn't be hitting too high of an RPM. Did the smoke come out of the exhaust, or does it appear to be burn off from something spilled on the engine? How many miles between oil changes to make the oil black?

The scooter revs high, like really high. Maxing out going down hill, it was running so good I thought I was going to blow it. If I were to change the final gear ratio I don't think it would happen.
The smoke was from the exhaust, When reved it produced more.
I don't ever count miles I normally just check it randomly or when I think i've been riding alot. positive it never goes over 100miles though.
If the rings are going, thats fine i'll just rebuild. I ride hard so its to be expected.

Letting a motor rev really high especially going down hill with no load is really bad for motors. You will be rebuilding and or replacing motors that way not to mention what will happen if it blows and locks up at those speeds.

Alleyoop I know, but its like its at constant load the whole time though. If I were to let off the throttle even a little bit down hill I would instantly notice it. Downhill speeds at close to flat speeds. Is that bad? I'm far from done tuning and testing the engine, it just accelerates fast and has a good top at the moment, and is reliable. I'm buying a new 150 to ride and upgrade in the next two months and I have enough spare parts to fix this one if anything happens. If it were too lock up I could handle it, just don't know about the cars behind me.. |
