im trying to improve my old 2002 850 kancil..
somehow i find it consume more petrol than usual..
got any comments on that?
A few things u can do is check your plugs(how long it's never been changed, normal copper plugs are good for around 15,000km, u can change them after that, i would recommend normal copper plugs as at least you won't feel hesistant to change them when due instead of those expensive plugs, think the normal copper plugs costs like RM16 a pack of 4)
Change your petrol filter, if your air filter hadn't been changed for a long time, change it as well.
Also get a good can of carb cleaner(i'm using CRC CLEAN-R-CARB, very effective, you can also use WD-40 but it disolves the dirt slower, the carb cleaner just needs a few spray and it's done) , remove your whole air filter assembly(the whole thing, u need a number 10 spanar or t-wrench to complete the job) and see if there's any dirt clogged around the carby's "mouth", you should see only metal inside the mouth, anything else that appears blackish should be dirt.
Here's a timeline for things needed to be changed regularly that most people usually neglect
- Plugs: 15,000km
- Air Filter 15,000km
- Petrol Filter 20,000km
If you don't travel much and won't reach that kind of mileage within a year's travel, change them after a year anyway, all these don't really cost much, air filter is only RM8 from Bosch, plugs are RM16 for 4 pieces, petrol filter is RM5, it does help in some way to keep the engine in tip top condition.

when u mod ur carb eng, like change UFO airfilter n exhaust system, sure more fuel consump. Changing sparkplug, put earth-grounding n volt stabilizer, will make ur car smooth n better (fuel consmp doesnt changed). Change to 13' rims n lowered abit. Sure u can clock better speed at the corner.
But for me, 660/850 carb kancil eng r not worth to mod. Plz dont waste ur money. Just go for L2 or L5 as this eng are not very exp. Around 3k should already in ur bay.
There's no point in using "UFO air filter" on the stock engine, stock air filter changed regularly would be good enough. Like I had mentioned, if the mod isn't too hard/expensive to do, it's worth to increase the response, of course if we are talking about modding fees touching RM1k and above, probably not worth it.
One thing I regret in doing is to change to 165/60R13 for my Kancil, it seemed to increased too much of a contact patch(no doubt handling is better) but the increased contact patch increases drag and increased the fuel consumption, probably the better idea is to get 155/65R13 as it will remain the same contact patch as the 12" tyres which is 155/70R12, i'm pretty sure it wasn't the increased weight of the 13" wheels as I have weighted both the stock 12" wheels and 13" wheels and they weigh the same as I'm using original Sparco NS-2 wheels, thus lighter in weight than most locally made 13" wheels.
