Just had my 4000km service and two things have changed.
1. My bike now pulls away from the line with less revs needed (which I'm happy about) and
2. My bike now runs rough for the first 30 seconds or so from cold (which I'm not happy about!). It coughs and splutters and almost stalls. Then I give it some revs, let it cough a bit and then it comes clean and runs fine. Starts first go when warm and runs completely smoothly.
I phoned the dealer and told him it was running rough when starting cold and he said all 2 strokes do that. Funny...my SR50 Ditech only did it since the service. And I've owned at least a dozen Honda Dio's and they NEVER ran rough, hot or cold.
Seeing as all he did was change the spark plug, I checked the type NGK R CPR8-E and it's correct according to the service book. I checked the gap and it was only .55mm and the seting for a ditech should be .9mm, so I set it to .9, but I haven't noticed any difference. Bike still running rough when starting cold.
Any ideas folks?
