What would cause this problem I've had starting my bike?
« on: November 09, 2018, 11:31:18 am »
Once fired up it (was) doing fine. This was a few months back first half of the summer before  a mechanic messed things up(if anyone remembers). I'm in the process of putting it back together and before doing so I just want to make sure I check all needed checked before I bolt it all up. It just felt like it needed more choke I guess. So my first thought was that little fork, if anyone is so familiar, that is cam actuated by the choke mechanism opening the throttle a tiny bit. I had adjusted it a couple times I recall to get it just right and it was perfect last done last winter so I thought it strange during early summer I'd have an issue hence I'm here wondering what else it could be. No other symptoms/issues with it. I just had to crank it over a lot, like as far as warming it up it felt, then after a few firings it would settle on and run just fine.

If no other ideas I may just pry that fork open a bit again but it's setting is so sensitive that point five a millimeter too much and the engine will soar with choke. Thanks guys!

You may have a bike in your sig but thar does not mean it is the one you are working on. Make sure all the carb diaphragms are in good order and slides move freely. Dont have a manual for that one but in all the Honda manuals i have there is detailed info on setting up carbs and choke mechanisms.

Doesn't this manual covers yours? http://cosky0.tripod.com/
