all the above
unless they angkut the whole bike up van, might consider chain it to something big

FI means battery die cannot start
fuel pump rosak need to replace
want to mod faster also beratus-ratus
if no mod, jimat and konsisten compare to carburator

sadly foreman also dowan do carbu liao, much work and less profit.

welcome to the club

the paint is part of assembly check, means it is done torque down or tighten.
follow the service maintenance

for owner maintenance, lube the chain, check tyre pressure, coolant and brake fluid levels

There are many options to those consumable parts: oil, chain, tyres
- there are normal chains which needs more oil interval, and O-ring chains that lasts longer in between

Pay attention to brake fluid and suspension maintenance, those can cause poor handling also (means scary to go fast)

waht tyre is rear using now? How old is it?
does the rear tyre slide in the wet when u turn?

in low grip situations (rain, gravel, sand) usually we try to brake upright using the front, rear brake will make rear tyre more easily lock

I can recommend Corsa platinum series (R26, Cross etc), Battlax BT39.

My experience tells me, is the rubber compound that determines wet grip, not the tread pattern. Tread pattern determines likeliness of aquaplaning, which is not wet grip.

the two models, are the extreme cheap and expensive tyre I have tried both wet grip are good
no matter how good, can still lock so bear this in mind

as long as once u release rear brake, the tyre grip back, is good liao - u haven't seen tyre that continue to slide even after brake release, this one really really bad

existing tyre can try use slightly lower pressure to improve grip

u try shop around and see... if not buy from shopee and bring to shop pasang bagi duit upah

Long time no see....

which is? 70/90 and 80/90?

the tyre how?
I use same size as you, but they look bigger like 80/90 and 90/80... Corsa all like that, especially the Cross is even bigger

compare the sizes side by side, should be able to tell how much bigger they are
hope they are good grip enough for you

I feel can race with it... hehehe

compared to what tyre?

yeah, Maxxis if Volans also good
others I havne't try for wet grip

I would suggest to get a dyno shop to do it properly.
Coil plug, ECU and plug gap needs to match, but usually it doesn't matter.

Non-adjustable, should be lasak for many many years

I am not sure... just curious, why?

tak pasti, got ask pomen?
