kancil 850 ex old model

[trxx]

my kancil 850 manual its lagging and slow when in gear 1-3 thats y is that ? is it because the stock parts in it or the stock factory tuning ? whats the correct gear ratio for this engine ? i will notice the diffrence when i accelarate cause even the 660 will start ahead of me bout 5-8 sec others car with higher cc sure go far better . it makes no diffrence when i press to full throtle.

any1 can explain this situation ?

gear ratio? the standard gear ratio is already correct by factory standards.

oh! u mean compression ratio kaa? no idea.

i suggest u change all these items and go tune back the carburettor.
1) Spark plugs
2) Air FIlter Element
3) Fuel Filter Element
4) Engine Oil (with bettery viscocity maybe..)

u may also need to adjust the valve clearance if necessary.

gud luck!
