Cold Start issues. By thomaspm (Read 640 times)

You all helped me in the past so here goes another question.

On my Jonway/Roketa 250 cc with the CF Helix engine when I start her in the Morning she runs very poorly that unless I keep my hand on the throttle she will stall out, once she is warmed up no problems what so ever.
Can someone please point me in the right direction what to start looking for.

Thanks in advance.

Check to see if the enricher/choke is working. You might have to richen the mix a bit by turning counter clockwise a half turn or so as well.

Might need valves adjusted too. I know mine runs rough in extreme cold temps. I have the Helix engine too. But mine started in 26 degree weather rough and 40 degree weather starts fine. I don't know what to cold a temp for riding is.. It might be 30 degrees. The 20's might be pushing it..
