One of the first upgrades you should consider is replacing the carburetor. The stock Keihin PE 28mm round side carburetor is outdated and can lead to bogging off the bottom. Instead, we recommend updating to a Keihin PWK 28mm carburetor. This will give your bike stronger acceleration right off the bottom end and help you push it to the limit. Plus, the fact that this carburetor is standard on other 85cc bikes is a testament to its effectiveness. Don't settle for a less-than-optimal performance. Upgrade your RM85 with a Keihin PWK 28mm carburetor today.
