my 250cc is over a year old and has had starting issues, since day one but it has ALWAYS started. now after a good rain or cold start it won't. that is until i take a blow dryer to it the metal stuff (not mechanically inclined) and heat it up... then it starts and stays running like a champ. i've changed the auto choke but still no avail... any help, sugguestions?  attached is the bike image!

What do you heat up with the blow dryer? Any motorcycle or scoot do not like to get wet. Water causes shorts so if it is left outside best you can do is get a cover for it.
Also when was the last time the valves where adjusted on it? The valves could have tightened up and that causes hard starts.

Oh my! Haven't heard from you since the old SD site. As usual oop is probably dead on with the valves. Fortunately the adjustment screws are on the outside of the motor, so it's an easy fix. (When I first read the posting I thought the Znen Roar's infamous starter clutch had gone out.)
JR had this in our files. You can also use the manual (in the files too) and adjust them with the engine off and cold.

[replyingto=alleyoop]alleyoop[/replyingto]Hey...yeah i've been offline for a while... all was WELL! ok this the is full story: 1) no garage but i do have a cover and use it. the bike started having trouble starting this summer after the major rains we had in NC. i would rain for DAYS almost 7 days a week. i noticed a lot of condensation in the speedometer after starting it and warming it up back then 2) the blow dryer is used on the carb (i think) the metal directly under the seat. in the late summer (65+ degrees in the am) the bike still won't start (rain or shine) i use the dryer for no more than 8mins... the bike starts  3) changed the auto choke...no change in starter issues 4) another 250 miles and it's due for another valve adjustment. my mechanic did find the vacuum wasn't sealed properly and fixed that but no change in starting issues i just find it WEIRD that the blow dryer is the only way it starts... i figured that out after waiting for the rain to stop and leaving the bike uncovered in the sun for HOURS and then trying when i get home in the pm... HELP? |

When was the last time the carb got a good cleaning? As I'm wondering if gummed up parts are being temporarily freed with the application of heat and kept working by the increased engine temperature.

ok so i'm probably the only one entertained--

Dang, thought I might have had it. Now I'm wondering if it is't the carburetor that is being affected by the heat at all but the nearby starter relay and any number of other electrical components located right around the carb.
P.S. under the tupperware on the right side.

You don't want to go through all that trouble and find it wasn't the problem. I was wondering if your mechanic might have one (carb) to test if that is the problem before you buy? |

May I ask what are your blow drying on the scooter....kinda strange.....it is not that hot, I'm in Texas and it does get hot here.. I have no probs....keep trying and maybe you will find the culprit....enjoy your ride...Which engine do you have...the 244cc Honda clone or the 257cc Yamaha clone....  |

i'm not fimiliar w/the engines... it's 250 cc Znen, its no Yamaha or Honda (at least to my knowlegde). today was 58 degrees this am so i had a heater under the bike and blow dryer at the top... it took 15mins but she cranked. Spandi... the starter button worked w/o applying the brake so i know the heat is affecting some other wires (not sure what though).... when cold i need the brake to make it attempt to start. but atfer the dryer no brake needed. this is like the blind leading the blind...  |

We need more information. Does it turn over (stater motor runs) and just won't fire? Or does it not even turn over? It's not real clear to me right now. It is likely not the carb. People on here for some reason like to replace those as their first guess but it would have to some how be physically damaged in order to be bad. Answer the questions above and let us know if you did adjust/check the valves in the last 1000 miles or so...

Hiya Honeybee, It's hard to figure out what you can't see, but it seems to me more and more like some type of electrical issue. In the area that you are using the blow dryer there are a number of components and wiring that I'll bet are being affected by your application of heat. BTW, the engine is a 244cc Honda clone (I have the same model as you) I found CF Moto stamped on some of the parts. Even though you said the valves don't need adjustment for another 250 miles I'd still recheck them. (hope you solve this "mystery" ) |

ok to respond to the last two... the bike wants to start but just doesn't catch. you can hear it trying but w/o heat it just doesn't start. the bike is closer to the 250 miles for the valve adjustment so i left the bike at the shop for that. but i don't think the valves have anything to do w/heat. i think the heat is causing something to connect that allows the bike to actually start, but i'm NO mechanic... i'm a fashion designer...so this is literally Greek to me.... we'll see what the mechanic says... i instructed him to let the bike cool overnight and see if it can start. since my bike stays outdoors (under a cover) i hope the indoors of the shop doesn't change the problem overnight. |
