I have a 4 stroke engine kit I bought off of ebay. It worked pretty well for the first couple of rides. I loved it, I had to just modify it right away of course. So I bought a Sick Bikes shift kit for it and liked it for the most part. I did get stranded out on my first ride though because the chain wrapped around the crank sprocket. There is a lot of moving parts than can potentially malfunction here. I also ordered the high flow air filter to squeeze out a little more power. Before the bike reached a peak high speed of 38.2 MPH, but with the new set up I could only get up to 35ish. The problem was when the bike got really warmed up it would run to lean, to the point of the bike only going 32 MPH. So I read up on jetting and happened to have a .028" drill bit so I drilled out the jet. That was pretty much the last time I really rode my bike. It ran kind of rough, from idle and I couldn't tune it with the low jet screw. So I probably went a little too big with the jet? This is what happens, I can do a 200ft lap in my yard, I would make about 1 lap but then it would stall out and die. It will start right up and will do maybe a ½ lap then die. Maybe its got something blocking the jet? Maybe its not getting fuel? After it dies I close the pet cock to see if it will still run the same? It doesn't start as well and sometimes it won't go 2 ft and sometimes it will go 100ft. I open the bowl and a good amount of fuel comes out? Ok so I'm going open it up and clean it out. I did see one speck of something. I repeat this procedure several times. I happen to have another identical motor kit, so I put in the stock size jet assuming I will be running like I did before but at least running. It ran a little better but still conks out after I back off the throttle then put it back on. I'm like screw this, I'm putting on the brand new carb and the stock jet! Along with an inline filter. I'm like cool its running great, I'm on my 4th lap and then BLAH! It sputters into a stall. WHY!!! I've tried countless runs each time trying to adjust the low idle jet from 1-4turns each with ¼ turn increments.
Whats the deal here people! I'm usually pretty good at getting small engines to run well, what am I missing? I filled the tank completely full but, but. did notice some of the black paint softening up where there was some overspray on the first ¼" of the inside of the tank. I did not see any debris inside the inline filter and fuel was getting inside the bowl everytime. PLEASE HELP! I really want to ride this bike again.
