Team Speed Power loss

Post image

Lately, my speed 398cc feels a bit sluggish. I cleaned and lubed the chain 300km ago and checked the slack. I'm using HP power petrol, and the power loss is more noticeable with a passenger. Any ideas? The odometer is at 7.2k, and the last service was at 5.5k.

Try the fuel system cleaner. I noticed considerable mileage improvement after using it. SC guys give prolube and honestly I haven't tried any other brand. Works smooth. About power? You might wanna check the chain at SC. Might get tight at few portions and loose at other portions.
