I just did a60cc kawi 72 Kitty cat had same problem. Mine was float height in carb.. I would check into an air leak aswell. If you don't have a leak tester there's an ole trick (soapy water) squirt it around ur gaskets if u see bubbles forming guess what... I'm only saying this Cu's its worked for me a few times when I would first start the engine up Cu's if its to hot it will obviously just boil off but like u said as soon as u start it than throttle it bogs. And its a smaller engine so you should have enough time to do a good look over b4 she gets hot. 1more thing make sure u check crank seals.

Shouts air leak, or poor fuel supply, running lean and hot.

A 2 stroke plug normally will be oily when you pull it out.

Is this motor oil injected.

yes it is oil injected, i run motul 2 stroke injector oil

Is it getting enough, there should be traces of oil on the plug unless it is running extremly hot.

Yes it is. Or should we say it used to be. Is there a spot for 2stroke oil that u can see.. I cant see it being blocked off like a blaster but its possible.

What plug are u running?.

 

[89blaster89]

yeah i think its getting oil, it leaks black crap at the header and put out slimy stuff out of the exhaust, theres a tank you pu the oil in on the side

 

[89blaster89]

im running a bpr4hs in it, its the correct one

Is air filter clean?. Try it without it n see..

 

[89blaster89]

yep filters brand new and oiled, i tryed without also and nothing

Has it been flipped or laying on its side for a period that could have caused an air lock in the injection lines.

Is it possible to do a leak test to confirm that it is airtight.

Is the pipe leaking, I mean blowing out exhaust gases, this will cause a lean mix.

Taking the air filter off could cause a disaster, it is already running lean.

I think u can cleannthe silencer on them they clog. There should be 2 screws on the back I think. What kind of slimy stuff Lol ... hmmm dry plug but slimy stuff out the exhaust.. id start with leak test.

 

[89blaster89]

the thing is, it ran fine and good for a few days, and yes the bike sat outside for 10 years unridden and it had old oil in the tank, i cleaned out the tank and put fresh oil, but it sat on its side when i was bringing it home in the truck

 

[jus_me]

Run a lil oil in with your gas.

We had a little 80 that died in the A a while ago, removed the muffler internals and she ran like a dream. I could be stuffed up with goop.
