Was going off to work today all happy after I sorted few more things on my bike today all for another issue to arise, but this time worried it may be something serious.
Some background info first.
Day Prior,
Things I did prior to the ride today,
I tried being descriptive as possible and please ask away for any questions, any help would be appreciated, also I am new to all this so please go easy on me.
Some background info first.
- Engine is on roughly 300 KMs (+-50KM) .
- Stock kit NT Carb, no aftermarket parts yet, apart from changing out the magneto that got rusted out by water 2 weeks back.
- Exhaust never cleaned.
- 66cc/80cc engine, model ZB-80JET-SR, recently put together 2 months back.
Day Prior,
- Clutch wouldn't randomly engage, had to quickly tighten it as I needed to get back from the store and need the bike to head to work an hour later.) Bike been hesitating to idle since then from a cold start (Choke 50%), but idles normally once I turn choke off and engine is warm.
- Ran out of fuel 10m from my home and just turned engine off after I noticed I was losing power
Things I did prior to the ride today,
- Replaced Fuel lines mainly because it already started to harden, discolour and more importantly the hose wasn't a straight path downwards to the carb.
- Seal fuel inlet port threads with teflon tape (Found out later fuel was actually just coming out air filter, but more than before strangely)
- Refuel with 24:1 ratio mix of fuel (Previously had 20:1) used 160 mL of Engine Oil and 4L of Petrol this time.
- Loosen the clutch one notch as I tighten a bit too much the day prior, noticed the bike would creep a bit with clutch completely disengaged.
- Going to work full throttle, maxing out at 41 kmph, all of a sudden the power just drops to the point I feel like I applied the brakes when I didn't and goes back up again (Plus new rattling noise of sorts, not sure where it's coming from, but I checked the bolts with my finger and they were snug).
- Happened few times on the way to work (4.5KM ride) ended up peddling half way being too worried (Went back home with the engine on uphill, happened again, but this time just twice and avoided going above 60% Throttle)
- New noise that goes away after turning engine off and just coasting down hill (Noise still there when clutch disengaged and engine on)
I tried being descriptive as possible and please ask away for any questions, any help would be appreciated, also I am new to all this so please go easy on me.
