I finished my bike yesterday and went for a few rides and everything ran great. I returned from a long ride and it wouldn’t start so I let it rest and it started and when on a long ride, now it won’t start, it sounds like it is going to start and bucks and engages a little. It seems like maybe clutch is slipping? Photo:
Won’t start
- Thread starter Mark W
- Start date
If it's brand new, the first thing I'm noticing is that you already have a lot of wear on the clutch pads!!! You're probably taking off from a stop without pedaling the bike at all!
Thank you, I will pedal more before releasing the clutch and continue to pedal. But first I need to get it to start. I expect a NGK B8HS-10 spark plug to arrive today to see if that would help . Would additional pictures, like of the spark plug or a video of how it sounds when I am trying to start it help?
New spark plug did not help.

#8 is way too cold of a plug... Use a NGK-B6HS (or a #5 because winter is here)
Install a new plug & test for spark

That spark plug you had pictured was very wet with gas,,, The spark will travel through the gas (& not jump the air gap).
Try the same test with a new (dry) plug.
Also... try spinning the rear wheel fast (& don't just walk the bike).
Another thing... tape off that white wire so it doesn't ground out.
