Smashed exhaust bike running lean

Recommended Posts

Hi I just bought a crf 150r and didn't notice till I got home that the exhaust silencer was smashed in. I rode it. It seemed fine. But I noticed that the engine was too hot to touch when I was done riding around the block. Seemed like it is running too hot. I checked the plug and it was white and slightly tan. Running lean. Do you think the smashed exhaust is causing this? Thanks so much for any response

You cannot read a plug that way, or on pump gas. Ignore the plug color.

The engine will always be too hot to touch after 3 min of running

If the silencer is restricting the exhaust flow, it will run hotter than normal
