Full Service for Engine

[MonoWorld]

My TA150 has traveled more than 81,000 KM. Is it necessary to do the full service for the engine such as wash the piston, block, head etc?

 

So far, there is no problem with my bike. Engine condition is still good. However, I heard from my fellow rider colleagues that doing full service when there is no problem, will invent new problems. This is the reason why I put off doing full servicing.

 

Please enlighten me. Thanks a lot.

No problem don't mess with it. Just do the usual maintenance on time and don't cut corners on essential things like 2T, sparkplugs etc. 2 strokers can be one of the lowest maintenance, but neglect it and results can be disastrous, usually piston jam.

Ya, you are correct, don't go and let any mechanics open your engine unless really bo pian. The parts in the engine are sensitive, and those bikes you see with white smoke are most likely 'operated' by mechanics who don't really understand the engine. There are only few countries that knows how to make engines, eg. japan. If it's so easy to open and put back, we (singapore) would have our own factories and a new brand!

So my advise is not to 'service' the engine, unless really necessary like piston jam. Honda/Yamaha etc engines are not fixed overnight, and they pay thousands to their engineers.

Dont need to do unless u wanna spend money n find trouble lo,.haha

"If it ain't spoilt, don't fix it"

 

This term IMHO is outdated already. All of us want to keep our engines in prestine condition, but not by not letting anyone opening it. Preventive maintainence is always better than corrective maintainence, most of the time less costly as well.

 

Many people are afraid of letting mechanics open their engines, why? They have no confidence in the mechanic? In this case, why are you still going to that mechanic? Experience is not gained by just looking at an engine, its gained by disassembling and reassembling it over n over again.

Engineers in Honda and Suzuki only design engines, they don't repair them. That explains the poor overall structure of the the engines when it comes to removing certain parts, top up coolant, take out carburettor etc. They make it easy to fit onto the bike as a whole but they do not make it easy for people to access the common components. Present designs are getting better but take a look at the older bikes and you will understand. Repairs, ease of accessibility of components are not on the top of their list.

 

That said, many people out there are unaware even when there are problems in the engine. why? mabbe cos they are new to the bike, mabbe its been like that since the 1st day he got it. mabbe simply cos he is not attentive enough. Why wait till your timing chain snaps, piston jams, valves go completely out of specs, cam shafts get worned out, con-rod snaps etc before you are willing to fork out the dough?

 

A yearly or once every 2 year check on the engine might save you alot less injuries and money in the long run and keep your engine running happily.

i agree..

[ANR Impex]

There is a distinct difference between opening the engine for preventive maintenance (valve clearance, cam chain replacement) verus stripping everything apart to "wash the piston, block, head".

 

So far, there is no problem with my bike. Engine condition is still good.

 

So why mess with it? Nothing is improved but there is everything to lose if something is not done right.

 

Besides, MonoWorld's TA150 is a 2 stroke, there are no camshafts to wear out or cam chain to snap. That's the beauty of 2 stroke. Put in petrol and 2T, it will run until it billows smoke, lose power, then you know it is truely time to recon the bore, change piston and piston rings. Regular maintenance of a few things will keep things running in both 2 and 4 stroke. The premature failure (under 100K) of most modern engines (Italian jobs aside) is either abuse or neglect.

strongly agree.. dont wait for problem come den fix.. u shld prepare for problems instead of wait for problems to come..

thx for all of the replies. really appreciated it.

 

mentioned above, what are the engine preventive maintenance for the two-stroker like my TA150? i mean not spark plug, 2t, etc but those inside the engine?

 

Thanks and would appreciate me if u enlighten me.

[ZXr400]

Use the right amount of 2T lo.,.,a

if u are concern about inside ur engine... do change ur engine oil (4T) often... n use gd engine oil... it this very very important regardless of 2 or 4 stroke...

AGREED!

[KeraKing]

if u want to do full service, i suggest u check out the piston n piston ring's conditiion.

 

for piston, its normal if the top part is black, as long as its smooth.

for piston ring, it needs to be measured to know properly if its worn.

also check the engine block's inside walls

once opened... change rings...

[wilson tan]

hmm..dun mind can i ask..

my rvf FN plate..milage ard 64k pluz..need to go for overhaul..??

valve clearance..?? any realli costs a bomb de service..??

[dinie]

u also need to check the cylinder liner if its scuffed or scratched.. even though it mite sound like the engine's working fine, ur well on ur way to a piston jam if either ur wall or piston's scratch.. so im gonna have to go with yes to going for full service annually even tho there's no prob.. jus open the top block only.. and change the gaskets and rings..

What's the average price of a full servicing?

[SlowButSteady Bro]

I've learn to basic servicing of my trustworthy RXZ engine from a senior mech during an emergency at night.The things that i need to buy is a piston,piston rings and con rod.With that i've managed to save on labour charge provided you must know how to tighen and loosen the screws.There's a tactic.

[Jehuty]

Full servicing of engine, isn't it the same as full overhaul?

[Eno]

What's the average price of a full servicing?

 

I give u the average price for JB workshops..

 

About RM40-50. Wash block, piston, carb. Doesn't cover changing of worn out parts and EO oil, spark plugs. (This is the price for bikes like rxz,125z)

 

For KR,SP or bikes with valve and radiator, its about RM80.

 

For SG, its about $100-140 for KR. Cleaning of block,carb,valve,piston,flush coolant. Doesn't cover changing of worn out parts, EO and Spark plug.

 

Full servicing of engine, isn't it the same as full overhaul?

 

Nope. Full servicing is actually called top servicing. Just service the top part of the engine. Usually done like 6 months once or more. Overhaul is like taking out your whole engine, wash and most importantly replace the worn out parts at the bottom part of the engine. Usually cost a bomb.

Just use OWS 3 in 1 engine and performance restorer. Problem solved

In the 70's they believed taking LSD would solve the world issues. And we not talking about the typical junkies, they were doctors and scientists.

[swashylahs]

Hey guys just curious, does full servicing actually prevents a bike from getting piston jam? Or only overhaul prevents that.

[ahkiid]

whr can i get to cheap replacement of piston n piston rod cames w bearings foir sp?does this counted as overhauled?
