Hi there. Currently my bike have some sort of losing power like loose clutch on gear or sudden lost of power when riding at cruising speed 100km above. Is it auto clutch problem? I already change to ikr (not sure the brand) cdi since the mechanic say it is the ori cdi cut off. My bike is 2 years old but already travel 30k km.

QUOTE(thianz @ Jul 31 2014, 09:02 PM) mean u pusing more minyak ... bike xboleh bla ??? Bike running well but can feel some kind of pausing during 100km or above like something choking the carburettor (already clean the carburettor).how long u din maintain ur bike adi ???  Normal maintenance. Every 3k will change the oil filter and engine oil(15w-40 or 10w-40). Every 6k will change the Plug. Every 1 year change the air filter. Sprocket and chain usually last me for 8 months before change. Is this anything to do with the air filter? After the last cleaning the problem start to arise but already open and change to k&n high air flow air filter but the problem still persist.

QUOTE(alexei @ Aug 5 2014, 07:22 AM) Very decently maintained. Better use 15W-40, higher film strength than 10W-40. Feels like the second one engine jerk when the throttle at the same position. Carb still the original one. using LC 135 V2.Which version of the carb is yours using? VM or BS carb? I worry is the BS carb, that the diaphragm may start to have problem. But, if it's the VM carb, let me ask more questions: - is it like throttle choke when you increase throttle? - or, is it like engine jerk when you keep the same throttle, while the bike accelerates steadily, and suddenly it happens? |

QUOTE(alexei @ Aug 7 2014, 06:13 PM) I think the diaphragm on the BS carb needs to be checked. I see. Is there any recommendation shop around gombak? I do ask the mechanic nearby my area to clean my carb but did not notice this problem. A reason I think of, is when the speed increases, the diaphragm supposed to go up like opening throttle. But, instead, it probably juddered and caused a choke at a certain engine RPM. Otherwise, if it does not cause too much trouble to you, you can safely ignore it.  |
