This is a classic sign of plugged tank vent, or in this bikes case a possible failed plugged EVAP system. The lack of air being allowed into the tank is preventing the fuel from flowing. Next time you go on your ride, carry both keys with you. 1 to run the bike, the other to open the gas tank cap to allow the tank to vent WITHOUT shitting down the motor. Ride as usual, when it bogs down, pull over, open tank, reclose after 1-2 seconds, and continue your ride. Report back if the bogging went away for a few minutes.

No hills
No; flat grade, uphill, downhill, happens when holding steady speed.

Has anyone replaced or cleaned the air filter yet?
I started taking the sides and seat off, but couldn't figure out how to get the air cleaner out. Has anyone here done it?

Just some more info for you. Yesterday I had a fuel smell whenever coming to a stop. Last night, I saw a video on youtube from a gentleman who had a confirmed fuel leak. He ended up tightening the fuel pump bolts. So today I checked my fuel pump, and each bolt took another 1/2 to 3/4 of a turn before hand tight.
1. Do you have a fuel smell once coming to a stop, from a higher speed / revs ? 2. May also want to check your fuel pump hardware. The pump is located under the tank, right behind where the speedometer gauge is. You do NOT have to remove any panels to get to the 4 bolts on it. |

Count what's on your bike. The easiest way is to count the plates between the links, and multiply by two.

Post #85 in this thread states what the chain is.
The rear sprocket on the 2021 KPM200 has 49teeth on 428 chain, and is off set (dinner plate shaped) so I couldn't find any other sprockets that I could safely switch to. Front sprocket is 16 teeth on 428 chain, this front sprocket has a 20mm shaft hole with 2 bolts and a small gold ring. The chain is 428 chain 128 links long, if you buy a replacement go with the o-rings |

![]() I agree 100% that it's easier to ride in lower gears. Lost about 2-3 MPH at top end going slight uphill, BUT it also less buzzy up there. IMO the 17T sprocket is what the bike should have from the factory. |

I had a similar problem with a CX500 with 650 motor I built. I put a high front fender on it, and that blocked air flow to the radiator. I didn't notice it until the radiator fan blew a fuse (my fault, my wire wasn't properly heat-shrinked where I soldered a splice). The fan was on 100% of the time, and when it failed I overheated. I ended up fabbing some wings to draw the air in from the sides. While you solved the problem, your fan may still be kaput. It'd we wise to check it. Also, while this was a simple fix, USUALLY rpm-related overheating is due to a bad head gasket. Combustion gasses leak into the water jacket and superheat the coolant. Charles. |
