NQ50 Bad Bystarter?
Posted: Wed Jul 15, 2015 2:14 pm
Hello everyone,
Backstory:
I bought my 86 spree two weeks ago, it wouldn't idle and i found that the PO had replaced the bystarter, left the extra tail of wires on rather than cutting it down to size. The extra wires came loose, contacted the exhaust which melted the insulation and shorted out the bystarter. I trimmed the wires and soldered them together, readjusted the idle and air screw to manufacturers recommendations, and the spree ran like it should.
Now:
Two days after the fix, the spree would sometimes idle really high (to the point where the transmission would engage and the bike rolls around 2-3 mph), I tried bringing idle screw out but it didn't do anything. After high idling a while (sometimes 30 seconds, sometimes 1-5 minutes), it will gradually rev down to a normal idle speed. Today, the scoot wouldn't start, it would turn over and over. Finally i bought some starting fluid, sprayed it into the carb, hit the starter, coughed twice and fired right up. I drove it around town at mostly WOT to clear it out, and every time I stopped, it seemed to alternate between the high idle and the normal idle.
Sounds like the bystarter is bad to me. Input? Also, is there any instances of people replacing the bystarter with a manual choke to avoid the issue?
