Motorcycle Repair: Yamaha PK 50 stalling, repair history, hi mike

Question
Dear Mark,
My son's Yamaha PK50 starts up but stalls when the throttle is turned. Any ideas on what's wrong? I think it's a model year of 2000. Thanks for your time and help! Mike  

Answer
Hi Mike,

Can you give me any details on this? Repair history? Was it stored for awhile? Anything added to the fuel? Anything intel would be helpful. Also, need an email addy as requested. I'll return repair info files.

Respectfully,
Mark Shively
