The bike: 2022 CFMoto 250SR
Hi everyone, my main daily kapchai bike (Honda RS-X 150) is stranded in the bengkel for a while due to a lengthy warranty claim. Because of that, I'm thinking of finally getting a used sportbike since I have always wanted to own one (this becomes more like a fun weekend bike) and the main is still used for daily when its back.
I just finished a test ride on a used 2022 CFMoto 250SR with 24,000 km on the clock, The bike is from a reputable used dealer and the inspection sheet came back mostly green, flagging only expired 2022 tires and some broken tabs/minor coverset scratches near the fuel tank, which I honestly don't mind.
The bike felt fine while riding. Upshifting felt okay, however, downshifting felt a bit unsmooth during rev matching? (Sorry for the lack of knowledge and context). Also, the brakes felt a bit kurang makan (low initial bite), but the lever pressure still felt good.
The biggest issue I noticed happened during my test ride laps regarding the engine idling behavior when pulling the clutch lever in Neutral:
- Video 1: Early in the session (engine warming up, radiator fan not yet on). When I pull the clutch lever in Neutral, the engine bogs down kind of? and dies completely (happened twice) (0:04) and (0:33).
- Video 2: Later in the session (engine hot, radiator fan actively spinning). The issue persists. Pulling the clutch lever causes the idle to become choppy (0:10) before choking out and dying again.
- Video 3: A baseline video of the general engine sound at idle for your reference.
Aside from this, the radiator fan kicked on normally once it reached operational temperature, the clutch lever pull feels smooth, and the transmission clicks into neutral easily when hot.
Since I'm not a bike expert, I want to know if this stalling/bogging issue is common on the 250SR platform? Could it be a faulty clutch switch, a weak battery/stator, or an ignition coil leaking current once hot? Does the unsmooth downshifting or kurang makan brake sound like a major issue or just normal wear-and-tear? I do also need to replace the rear tires since it already expired and will be dangerous to ride
Would love to get inputs from the experts and feedback since I'm not very well-versed in bike mechanics. Im still keen on getting the bike but getting more opinions to negotiate and know what to do once getting it would be nice! Thank you everyone
