I recently replaced my points/condensers. Sadly, they were Daiichi (made in Japan, not China), even though they were being sold by some other company (forgot which atm).
When gapping and timing them, I had to advance it nearly all the way to get it dialed in. I know that was an issue confirmed by HondaMan with the Chinese points, but I haven't heard anything about the Japanese points.
At first they were performing adequately. Only problem was ill-tuned carbs. Rode about 100 miles with them no problems. Well, on a ride yesterday, I started getting bad throttle response at low RPMs; stumbling off idle, can't get a smooth ride at lower throttle positions, and eventually started popping and farting and backfiring at WOT. Those were the same issues I had with my old points when they were gapped wrong and eventually just plain worn out.
I haven't been outside to check anything yet, and probably won't until later this afternoon.
I know someone is going to suggest electronic ignition. I don't have $300+ to spend on that right now, unless someone would like to sell me a used one.
