bike servicing
-
can somebody tell me when to go for full servicing and its cost... and when to go for overhaul? under wat circumstance need to go for tat?
my normal servicing now is only change spark plug and engine oil only. enuf? wat else is needed?
sigh... realised tat my bike now ride not so soon oreadi lei... very slow pickup... not as nice to ride as in the past... tinkin of goin 4 full servicing... -
remember to check your brake pad and clutch... dun need to save this kind of money....
if u want fast, then go service valve lor...

what about phantom eh??? i only change like spark plug, engine oil and clean cabarator..some more what eh??
btw how often do we need to change break pad?? 1 year, 2 years???
And how often do we need to service eh??? -
oh yeah one more thing, how much does it cost to service valve eh?? what is valve btw ??
-
correct me if i'm wrong....coz your valve after riding for a certain mileage...there'll be carbon deposits/dirt...thus affecting the performance...thus u'll have to service/wash it...Originally posted by kokomo:wat does service valve means?

a valve is a device that allow air to flow depending on rpm....when combustion increased ur valve open thus air flow is more and much faster!certain bikes valves open according to rpm(eg 6k open, abit 8k open more).
some bikes have their valve suddenly open at once.
some bikes have their valve tried open(meaning open all the way even at low rev!!that r the racing bikes!!!

hi
i know of full serive abt 70 bucks for washing piston/block/car/vavle.i think if u love ur bike do it every 10 000 km.
I have done it once and i dun realli feel the diff but definately vavle opens more easier.
my two cents worth.
cheers -

best is that every 5k go for normal service and every 10k go for full service ...
that what i done to my SP last time -
other den looking at ur RPM, hw u noe when the valve opens?
can u actualli feel it (as in u feel ur bike goin more smooth" or something? -
pipe sound changes...i think??Originally posted by snowball72:other den looking at ur RPM, hw u noe when the valve opens?

for yamaha 2stroke bikes wif ypvs u can hear the valve working.. -
I have posted this before but i cannot seems to find it...
I try to put my 2T on my phantom 150 and it was like so difficult to put the bloody 2T inside..I had to pour a bit and then had to shake my bike to let it flow down..Had to do this until i so many times..Sian eh??
Do all phantom 150 having the same problem or is it me???? pls advice or tell me the situation of your phantom bike.....thanks everyone!!!!!

you will have a feeling that the bike has a sudden increase of power ...Originally posted by snowball72:other den looking at ur RPM, hw u noe when the valve opens?

Where is it that you service for onli 70 bucks?? can give address??Originally posted by tzm^21_shoei:hi

to add on, this so called valve is the "power" valve for 2 stroke engines, located after the exhaust port. not to be confused with air-intake valves like boyessen reeds.Originally posted by tOngEh:a valve is a device that allow air to flow depending on rpm....when combustion increased ur valve open thus air flow is more and much faster!certain bikes valves open according to rpm(eg 6k open, abit 8k open more).

4 stroke engines have an exhaust valve that closes completely to allow compression of the air-fuel mix as it enters the engine. 2 stroke engines have no exhaust valve to do this, only an exhaust port, that is open and closed as the piston goes about its cycle. it's a little hard to visualize lar...
2 stroke engines compress the air-fuel mix by use of back-pressure from the combustion wave. at low revs, the power valve is "closed", but in fact it is only half-closed. this helps charging of the new air-fuel mix for the next engine revolution. it is at this time when carbon deposits (due to incomplete combustion and 2T) accumulate on the valve. given that the rider doesn't "open" the valve every now and then, the carbon gets caked up, and jams the valve. aggressive throttle action does help prevent this jam, but doesn't prevent carbon altogether.
race bikes can afford have open valves at all rpms because race riders maintain a high rpm most of the time. an open valve provides the maximum power (among other things working together), so they get the best out of their machine at all times. for us, it's not practical because we have traffic lights.
honda's RC valve (the one on SP, dunno about other models) works by rotation, so it's not so easy to break lar, as compared to aprilia's power valve.
hope this helps...

clean carburettor also? must ask the more experienced ones when to do this. but sounds alright to do together with the engine oil and plug change.Originally posted by kokomo:can somebody tell me when to go for full servicing and its cost... and when to go for overhaul? under wat circumstance need to go for tat?
my normal servicing now is only change spark plug and engine oil only. enuf? wat else is needed?

overhaul got a lot of definitions leh... full overhaul means changing engine block, block cover, piston, con-rod, crank-shaft, bearings etc. aka full engine rebuild.
top-end overhaul means to some changing piston or piston rings.
er.. in most cases, "overhauls" are done when your piston jams. depending on the extent of damage, the mechanic may suggest a few things to change lar.

i dunno the names of these gizmos.
at the root of the needle, and another spot inside.
before that, bike was not ridden for 1-2 months.
