Engine bogging down.
2020 Kpm200 question.
4600 odo Bogging down when riding at steady speed. Seems to happen more so after fill up. Any ideas? |
Bogging how? Like it's losing speed gradually, or suddenly losing speed and picking back up?
Are you going uphill? Even slight hills cause these to slow down a bit. |

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?

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. |
I had a question on the chain (turner performance gold chain) when I go to purchase a chain it asks me how many links should the chain have? there are like a million options. from from 78 links to 142 links.. thanks for the help

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. |

Toying with my exhaust, measured everything in hopes of helping others in the future.
Stock OEM black exhaust: Pre-cat pipe size: 35mm OD Cat area pipe size: 44mm OD Post cat pipe size: 35mm Replacement Stainless manifold from Aliexpress, eBay, Amazon, etc. Front header pipe: 36mm ID, 38mm OD Rear header pipe (slides over Front header pipe): 48mm ID, 51mm OD. |
I'm running this setup on my KPR. $160 shipped including the muffler from eBay was too great of a deal to pass up.

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. |

Had some spare time today so I made a laminated quick reference sheet for the bike. probably tape on on the inside of the battery panel, and leave the other one in the tool box
