I own a 2007 model Honda unicorn. I am having an issue (releasing clutch and bike accelerates very horribly) at every cold start. I have to heat the engine for 2-4 minutes and then it is ok to accelerate the bike. When the engine is hot this issue is almost not existent. I checked the air filter, spark plug, carburetor. Carburetor slide shows some signs of wear (piston shows smooth shinning surfaces).
I tried to find carburetor side for Honda unicorn having part number 16111-KSP-912 but all in vain. Where can I find this? Please help me and let me know if any HERO motorcycle carburetor slide can work.
Also, please tell me what might be causing the issue? Spark plug is ok. Air filter is new. Clutch plate is ok as this issue is only dominant at cold start.
