If ever that can help, here are 2 engine starts, the "hot" one just after a 30Km commute this afternoon and the "cold" one after a 2 hours rest! Speaks for itself...

It shouldn't - poor valve clearances are usually associated with hot engines, where the slight expansion of the valve means it doesn't seat properly and compression is reduced.
Thanks

Time for an update!
Tried the initialising procedure. It helps on the first start but then once the scooter has been put aside for a while the problem comes back again... strange!
Will definitely talk to the mechanics about the valve clearance and will let you know. Sorry for the (maybe stupid) question but how does a valve clearance issue affect the engine startup only when cold?
Thanks

Hi Guys,
Thanks a lot for your replies. It is very true that the "cold start" issues could be re labelled mid-HOT start issues since we are now experience 34+ degrees Celsius everywhere around the island...
Karl, I have tried to initialise as recommended. I have had to do the procedure twice but on the second attempt, seems to work. However I am not home right now so I will only be able to give you a proper feedback in a couple of days.
Thank you all for your help. Will keep you posted.

PS: Karl, the 250i is primarily intended for the Asian market. In Mauritius we have a (rather stupid) duty of 75% on motorcycles above 300cc. So the 350i is too expensive here and the agents that imports the bike prefers to order the 250i. We also have the AK550 on special order... but it would cost you approx. US$ 17K...

Hi everyone,
Since it is my first post and by way of introduction, I am from Mauritius and the proud owner of a Downtown 250i since October.
As from the moment I got the scooter I have always had a hard time with cold starts and always have to feather the throttle in the process. When the engine has been running for a while, no issues and it starts up just fine. The bike has 2500km on the clock now.
I have brought the bike a few time to the Kymco dealer and have had the MAF sensor changed, spark plug checked, idle speed checked, diag test machine found everything else ok. The problem however remains...
If anyone would have the faintest idea about what to look out for?
Thanks & Happy New Year!
