Good idea ... if you have problems with the way the bike is running ... take a passenger. (You have a full licence right ??) It's always nice to have somebody to help you push it ...

I mean, are there visual cues that tell me it needs to be replaced? So far as I can tell, the engine cutting out could be anything from fuel line blockages to oil problems. It's not really that dumb a question haha

No visual clues if you can't see the air filter.

As to actual issue ... you start by checking the air filter. As it is usually the problem.

Then ... move on to the more difficult things.

With the baffles butchered ... does it still sound nice when you're pushing it ... ???

just got the filter out, it's sitting in front of me.
it's just a sponge.
what am i looking for?

and the baffles just have holes in them, they sound nicer than the bike stock. but not quite how i'd like it to sound.
Pushing it makes it sound a little muddy, unless im going slow in a high gear

The bike will feel strangled and be leaving sooty black deposits on the spark plugs with a blocked air filter, may also get harder to start.

I think you should also look at the small black vacuum line to the fuel tap on the tank (assuming it has one) and wiggle it when the engine is warm (it may be expanding with the heat and causing the diaphragm to close)

First things first, pull the park plugs and compare them with this here:

Then pull your airfilter element out, it should look like:

If your air filter has sooty or dusty crap all over it or noticeable colouring differences, get a new one.

I'd then pull the fuel filter out and check that, yet again, anything that's in it that doesn't look like it should be, replace it.

thanks man. yeah my filter has a big oil stain on the inside white rim. i'll get a new one tomorrow.

I'll check the fuel lines now, the Manuel says nothing about where my fuel filter is

You'll have a fuel filter inside the tank, you have to remove the fuel tap and it should be part of it, sadly that means you have to drain the tank

Stick it to your mouth and hold your nose. Breathe through the filter. If you have trouble doing this ... your bike will too. Clean the filter. (Unless it's a paper filter) ... hot soapy water will do. But a bit of petrol will do. Wring the filter out and let it dry. THEN re-fit it and try starting/running it.

Will somebody tell the OP where the tank is ... ??? we may be here all night ...

sounds like a fuel problem as per a couple of other replys. might be a blocked breather in the fuel cap as it fires up after a little while. check the fuel flow to the carb by taking the fuel line off and letting it run into a container, let at lest two liters run through the flow should be steady the whole time. Your bike has a vacume tap so to get it to flow you will need to locate the vacume line and suck on it to start the fuel flowing then block the line off by pinching it shut to keep the fuel flowing (or just keep sucking your choice). if the fuel stops or slows down first take the fuel cap off and see if this gets the fuel flowing again, if not its a tap or filter problem clean the filter as the earier reply or strip and clean the tap. While you have the vacume line off check it's condition as a cracked or leaking vacume line will cause the same running problems.
