Hey Guys, Got a quick question, cause I'm a little bit lost. Recently had some timing issues and what not but they seem to be sorted, however now it seems when I sit in 5th gear and cruise at around 80kmph for an extended period of time, the bike starts to stutter and I lose acceleration...

Hey Guys, I've hit a massive wall with my 1975 Honda CB125s. It won't start! I've been riding it for about 2 weeks and was running perfectly, then I parked it up and went away for 5 days and when I came back.......nothing. I've checked the spark against the engine and it's sparking strong...

Ok so last night I was riding to my friends place on my 75 CB 125. When I stopped at the lights, I noticed that it was loud and then to my horror discovered that my exhaust had come away from the cylinder and little flames were coming out. I immediately turned the bike off and pulled over. I...

SO CONFUSED! Bike is a 75 Honda Cb 125s. Current jets are stock Main 105 Pilot 38. Runs perfect for around 30 minutes but then starts to bog a little on full throttle and then spark plug gets sooty (dry carbon not an oily wet carbon). Figured I needed more air to lean it out (ie go down some...

Hey Guys, My Cb125 has a 6 volt battery system and I'm having major troubles keeping the thing charged. First, I thought it was the Rectifier, or Stator so replaced them but I'm last night my battery went dead. Now, it hasn't been ridden in about 2 months since the new battery went in, but I...

OK so I'm pretty sure I've got this right but just wanted to check with you experts before I spend considerable time tooling around. I'm tuning my carb on my CB125s and I got it to a nice point and was just tuning the Idle when my spark plug fouled (it was a NGK D8-EA) I had a spare plug the...

Hey Guys, Basically finally finished my build and have found that after an extended period of riding the bike starts to die when I use the indicators or apply brakes. 3 questions: 1. Is this because the battery is draining? Or am I looking at a different problem? 2. If it's a battery draining...

Hey Guys, Long time reader so thought I'd post now that I've started doing some work on the bike. 1975 Honda CB 125s with 4*** on the clock. Not bad, pulled it out of an old blokes shed. Works: Drag Bars New flat seat Expose orange tank. Carby Clean. New Indicators Tail light. From Sydney...

Hey Guys, First build and I've hit a stump. Basically, the bike wont idle anywhere below 3000 RPM. Did have it idling around 1200 which is where it should however just put in a new battery and now i can't get it to ideal. So I turn the idle screw all the way in turn her over and she idles high...
