[Technical] Queries for TA150

Knock his head and ask him go fly kite.

 

knock your head, not his head. by right you shouldn't add water. should add coolant with the proper mixture.

 

also, if the coolant system is still good, ie no leaks or overheating etc, you shouldn't be needing to top up coolant. keh kiang top up will only lead to it overflowing when the bike comes to full operating temperature.

well overflow feauture means cap is in top condition...i wouldnt worry too much about it...if dont overflow i will be worried.

sounds like your speedocable needs a lubrication. take them apart, put them on a "drip", and you'll have a nicely lubed speedocable.

 

 

do mean after i lubricate my speedo cable, it will be fine? i ask a mechanic to inspect for me, he took out the cable and used a flathead scewdriver to turn the gear, needle jumps around while he turn the gear and he told me the unit is faulty. just wondering whether it is possible to repair the unit? wanna avoid changing the whole unit if possible.

Must well knock yours also. The prev owner is implying that there is no need to maintain/check the radiator status.

What are your chances that the radiator is in perfect condition and requires no top up from time to time? Even so, are you going to take his word for it and not bother about?

Not forgetting the convention of flushing the radiator yearly. Don't say old bike like ta150, even 1, 2 year old bike like mine I check from time to time if any fluid levels need topping up.

 

That said if you are so confident about your machine status, I guess thats your gain, but I'm not going base confidence on what some one else say

[newcomer]

Chill bro, why u getting so worked up. Where is it stated that the previous owner implied there is no need to maintain/check coolant status? I also din say anything about not bothering coolant level but it seems you implied so...

 

He said it is not necessary to top up coolant, and rightly so. However, it is mandatory to check coolant level occasionally to make sure there is no leak. A working cooling system, not necessary perfect, does not require topping up. If you find that you need to top up your coolant every month or so, you will need to bring it to a shop and have it checked out. It could probably be due to water pump mechanical seal, hoses, cap, head gasket, cracked cylinder, etc. Not doing so and falsely thinking that this is normal for an old/new bike will only exagerate the problem in the future. The worst case is for the coolant to leak into the engine.

My bike which is more than 10 years old does not need topping up at all for the 1 year that I have rode her. I changed the coolant after a year and the level was only a few milimeters below what last year was. I guess this can be accounted by evaporation from the once or twice engine overheat I experienced in jams.

Topping up of coolant is only temporary so that you may drive/ride the vehicle to a workshop or emergency when the coolant level is suddenly below the low level mark. If you're not familiar with the type of coolant you use, I wouldn't advice topping it because topping it with tap water will only dilute the coolant. Tap water is also known as hard water and they can corrode your cooling internals severely, and I have seen it too many times. Unfortunately, ppl still use hard water. Even with soft water, it should still be propotionately mixed with the same coolant in your engine.

Hope this clears up the confusion.

haizz not worked up, just stating my pov.

Whatever floats your boat bro...

thanks for sharing. i learnt smth. even with batteries =)

[mepkoh]

;5535235']its not for fuel.

 

if i am not wrong, its for EO or 2T.. ( i cant remember.. but i think its for 2T)

 

how to check if its working? mine nv once light up during my 3 yrs of ownership.. maybe coz i topup 2T regularly and service my bike when its due for servicing.

is it the orange indicator??t his is the eo low pressure switch for the engine.

it should light up when u turn on the power via the igniton switch...once the bike is started the pressure build up with turn off the orange indicator.

 

if it lights up while u are riding...u have to immediately stop and top up the EO...(proceed to the nearest shop to buy some eo)..if not damage to the engine is a high possibility. if top up eo doesnt work..proceed to the workshop for trouble shooting..

it is best not to ride if the orange light is turn on....or else risk damaging the engine..

Glad to be of some help

[ahcaibiker]

Hey, need help from anyones' helpful inputs. i've just discovered a minor leakage around my TA150's 2T reservoir area. i mean minor cos a puddle does not form at the btm of my bike after parking at the carpark overnight but i can see drips of 2T on my engine side cover.

 

On cold start, the exhaust tends to produce quite abit of white smoke but not enough to feel the carpark with white smoke and the white smoke gradually decreases as the engine warms up, when the engine is warmed up, when i open my throttle big big while on neutral (stationary), i can barely see the white smoke, can see but really very minimal. My 2T consumption rate is very low, top up a few weeks ago but still got at least 3/4 in the reservoir. It seemed the leakage have been going on for quite some time as i saw quite abit of dried 2T mixed with dirt on the inner side of the chrome oval cover.

 

May i ask is this normal? im very paranoid about piston jam as the repair costs gonna burn a big hole in my pocket is it really does happen. i wanna spend as little as possible on this bike as im saving up for a 2A bike.

 

Can anyone share abt any valuable info on how to look out for signs of piston jam so i can prevent it from happening before it's too late. many thanks.

just a add on. if i see white smoke emitting from exhaust it means the 2T is being pumped and mixed with the air-fuel mixture before being ignited in the engine right? so does it means my 2T pump is working fine and there is no cause for alarm? I know 2T helps lubricate the engine and w/o it, a piston jam is very likely. thats the additional trouble 2 strokers has. should i add 2T manually into the fuel tank every time i top up as a precaution? i see my friend's who rides a wr200 add 2T into his fuel tank everytime he top up fuel. and how much 2T should i add for every litre of petrol? pls help. thanks.

[mepkoh]

white smoke...this is a sign of trouble...water leaking into the cylinder a high possibility.

suggest u confirm whether your radiator is loosing water..

another source coilud be eo or 2t.

2t mix ratios??

 

if u are a hard rider..

 

i would use 1:50..or20ml/L petrol

which means 1 L to 1000km ride(at 20km/l)

 

or 1:75 for a normal ride.

hey bro, i studied automotive technology back i was in ITE, i can apply for a job to be a mechanic with my cert. i have basic knowledge how a engine work in theory and practically. my radiator is working perfectly fine. it is common knowledge that having white smoke emitting from exhaust is a sign of 2T being burned. if u say having white smoke is a sign of trouble then all the NSR 150, KR 150 and RXZ 125 on the roads all having serious trouble... i've seen a kr that produce so much white smoke that it can blanket the whole multistorey carpark like a smoke grenade. not trying to flame you or anything. i thank you for your input but pls refrain from misleading people who don have such knowledge. No offence, thanks.

anybody can give any reliable info on how to detect piston jam? i mean the telling signs of an impending pistom jam. this will help me and others who dunno to prevent serious damage to the engine which requires a major overhaul, and that is not gonna be cheap.

 

i just located the source of the 2T leak. it is the right at the bottom of the reservoir. there is a rubber hose connecting from there and it links to the engine. it is oozing out 2T even though there is a rubber hose retainer on it. do i need to change the hose?

What he is saying is that even if you are riding a 2 stroke and your 2T mixture is set correctly so that if doesn't produce excessive smoke, if suddenly your bike smokes more than usual, there are possible causes that require your attention.

 

In actual fact, 2 stroke engines should not smoke so much, and if it does, it is either due to a problem, incorrect setting, or the rider just thinks he is a lacer and overdose the premix.

 

No one is saying that you are unknowledgeable or anything, and no need to use your "certification" to prove that another is intentionally misleading others. He is likely to be speaking from experience and giving his honest opinion, just as you are.

 

peace out

[Wizard]

is it the orange indicator??t his is the eo low pressure switch for the engine.

it should light up when u turn on the power via the igniton switch...once the bike is started the pressure build up with turn off the orange indicator.

 

if it lights up while u are riding...u have to immediately stop and top up the EO...(proceed to the nearest shop to buy some eo)..if not damage to the engine is a high possibility. if top up eo doesnt work..proceed to the workshop for trouble shooting..

it is best not to ride if the orange light is turn on....or else risk damaging the engine..

 

Hi there,

 

bro hamsterwhale have already replied earlier correcting that it is an 2T indicator. Means the TA150 is running low on 2T and need top up.

 

and anyway from my understanding, the use of EO on a TA150 is for gear change only..

 

so i am not sure if we are talking about the same issue here.. this thread is mainly for TA150.. so perhaps we should be more focused.

There are no guarantees in this world and the best any can tell you about the contents of a black box is only a best guess, just as your "certification" may help you to understand. A probable sign that a piston jam is about to happen is lots of abnormal engine heat, lost of power or greater than normal engine braking. As you can imagine, when there is little lubrication left in the cylinder, the amount of friction between the piston and the cylinder wall is greatly increased, causing overheating and severe loss of power. And when the engine finally stops the piston jams and refuses to move until either it cools down and lubrication is restored. This kind of piston jams are usually recoverable unless there is damage done to the piston or cylinder walls that causes the chamber to be unable to contain compression.

 

But more often than not, things usually function just fine until wear and tear finally weakens it to the point when stress reaches a certain threshold and the component just breaks, causing a total failure to the engine. This can be experienced either by the presence of loud sounds, loss of power or rear wheel skidding

yea in 2 stroke engines, the Engine oil (or gear oil) is only for the gear box. The piston, crankshaft area is lubricated by 2T

[newcomer]

Aiyo you guys should relax a little la. I do admit Snapei your snappy reply to ah cai is rather heavy handed and might come off as offensive to others. After all, everyone is here to learn. Good write up on the white smoke thingy. 2strokers do emit a plenty bit of white smoke when cold or hard revving - it's quite normal.

[Wizard]

I agreed that ta150 does indeed emit white smoke.. but its minimum compared to most if not all the 2 stroker sports bike (at least on mine)

 

when i had my ta150, the amount of white smoke is not really visible unless you have a vehicle headlight shining behind you.. or when just the bike in the morning..

it could also be due to i nv tune the 2t mixture too rich..

[rafaeltsp]

Hm, I've been experiencing white smoke too. A lot of attention sial. Previous owner accidentally put too much 2T...

 

Anyway, is the rattling sound normal while riding?

change the hose if its a crack too far up...if not u might juz wanna cut off the potion thats slightly towards the end, but then again, ur prolonging the inevitable only....

i dun have a proper education cert so does that mean my reply all this time in the forum was worthless???

piston jams cant and will not possibly be foreseen even in the last 10secs of the working life of the piston....what u've basically mentioned is the last 1-2 seconds of the ending lifespan...if a piston jam can be foreseeable, i doubt piston jams would even happen in the 1st place tio boh???

what rattling sound???very vague cant really diagnose for u...might be a loose nut or the IU or someother things loose, maybe u can help by looking out from the general direction of the rattling sound, from there u can narrow down where its coming from...

oh btw wat bro mepkoh has highlighted is indeed a true proper working 2-stroke engine, what u've seen at ur mscp is a work of a mat rempit, or 'boy racer', 2t valve open big big big, when they whack the bike sure confirm plus chop no piston jam...

 

and may i bring ur attention to another thing, if hypoettically what u say is true, then why would LTA, NEA or TP even bother to book those 2 stroke bike emitting excessive amt of smoke(S$700 fine)???even by law its allowed to emit smoke???

 

nonetheless, as wat bro mepkoh has mentioned earlier, i might need to correct what he pointed out, water getting into a chamber of a stroker engine is only by fuel contamination, or 2t contamination...

 

i dunno if u know that a 2 stroke engine crankcase is only seperated from the radiator water by an only 5mm aluminium wall, and that theres a shaft travelling from the engine crankcase thru the wall which in turn drives a impeller that pumps the radiator coolant...theres a water gasket there, if its broken it'll leak water into the transmission fluid(aka engine oil) and the EO will turn cloudy like limewater reacting to carbon dioxide ( this is none related to wat u ask, but its juz a spare info)

 

Cheers!

Ya la... its like asking, where got TP, where got road block, if we know all this, no one get booked liao

 

Taking preventive measures is better than always having to react to circumstances.
