hi guys. i gave my bike to a friend and he drives it every day. however, he said that the motor got mini mini problem.
when i ride it today, I feel like it lacks power even though he just serviced it last week with 5w40 fully synthetic oil.

problem I found:
1. when full throttle, it is slower than say 80% throttle.
2. the engine is rough and vibrates slightly
3. the meter glass/plastic cover vibrates quite noisy ketak ketak ketak sound when driving
4. the gear is not smooth i.e. when I wanna enter 1st gear, sometimes it wont click until I release clutch and press again. it is better if I don't use the adjustable clutch to shorten it but it still happens occasionally.

any idea what's happening with this bike? he did raise this issue with his regular workshop but they are not so familiar with this bike. any recommended workshop around old klang road, bukit jalil, or sri petaling?

thanks yo

is that the only service done to the bike?

what else need to service?
air filter? this motor no oil filter.
brake oil?

wow, this is where the problem starts
the bike is neglected
google also can find this bike has oil filter

search a bit lah, regular maintenance stuff... oil, air filter, spark plugs, head service etc

neglected.... ok...

can u find me the oil filter for this bike?
regular maintenance stuff every 6 months by motor kedai. air filter changed once. spark plug still ok. what's head service? cabut and clean the carbon? on a 1k+ mileage bike?

enlighten me. thanks ya

Oh, it's a brand new bike? should go to SYM service center, right?

problem I found:
1. when full throttle, it is slower than say 80% throttle.
- it's a standard bike, not tuned to utilize max throttle

2. the engine is rough and vibrates slightly
- no idea, send to SYM

3. the meter glass/plastic cover vibrates quite noisy ketak ketak ketak sound when driving
- send to SYM, under warranty?

4. the gear is not smooth i.e. when I wanna enter 1st gear, sometimes it wont click until I release clutch and press again. it is better if I don't use the adjustable clutch to shorten it but it still happens occasionally.
- maybe the new oil is not suitable for the bike

its old 2018 bike but very underutilized that's why i gave my friend.
1. i dont remember it feels like that
2. yea sending to mforce seri kembangan
3. also ask sc to help check
4. using yamalube now.

tbh I can't help much
I googled VF3i oil filter, and can find it. Under a metal cover, paper element looks like.

some of the items are due by time, not only mileage - plugs and tyres are some of them

clutch can be mechanical or unsuitable oil, if you feel the problem arose with new oil, then change it. I've encountered many cases of poor match between oil and clutching, so each of my bikes use different EO

good luck

pomen told me dont have. i find youtube change oil guide also dont have.

another one inside oil drain plug

prob 4 sounds like you didn't fully disengage the clutch
clutch cable is wear and tear item
if not lubed regularly, it will stretch faster so you need to pull the lever more than when it's new

wow need to remove the engine cover to change the oil strainer inside? how often u guys do that? every oil change?
no wonder my pomen said no oil filter outside

sending to sym to check

The video did not show that they removed the engine cover. Just the oil plug to drain the existing oil. Oil strainer is replaced every oil change/service unless it is the reusable type.

u r looking at youtube vid. that's the normal service thus surely we will wash the oil strainer and the magnet.
look at the TikTok video instead

first time hear that no oil filter. if u refer maintenance manual booklet, there is oil filter location. it is even stated in the maintenance schedule.

ive clarified with my pomen, he said no replacement filtrate which is normally disposable. only for cleaning just like stated in the manual
