could it be cagiva mito ? haha.

[lacrimosae]

Btw, anyone has any idea why most of the time, some of you guys throw the balance gear oil away??

 

What difference / effect will I get if i kept the spare 400ml for next round?

 

I always keep the balance to combine with the balance of the next oil change. Can keep for the subsequent change. 5 years, and no problems so far.

 

But could be because I change gear oil so often, I can't really tell if using leftover new gear oil actually is detrimental to the clutch. haha

[yongboyboy]

my rs 125.. die off very easily..

eg... my rpm always stuck in between 5-7..

very hard to go up.. but when i manage to bring it up to 9. the whole bike just dies off.

 

next.. during normal riding.. the bike will die off on its own at times..

 

when to planet ytd. was told maybe the piston got something wrong.. valve might be broken...

 

any ideas?

he suggested that i put my bike there.. might have to change the whole block.. and overhaul

Yes I had a niggling suspicion that 'babymitto' might be the Cagiva Mito. But why call it a baby? Because it's only 125cc? And what's with the additional 't'. -.-

Haven't you noticed that the general population are no longer able to spell in emails, SMSes, and on instant messaging like MSN?

 

I type my SMSes, emails, and MSN messages out in full sentences, but I don't know of anyone else who does, save for myself and circle of friends.

wahahahahahhaa!! reminds me i taking O'levels last 5 years, history.

all write in SMS.. LOL!. 20mins ending, i do my last check. knn! horror!! i notice write in SMS language. LOL!

Valve broken???

Change the whole block??? (wow, what a crock of bullsh*t)

 

LOL

 

Check your valve yourself. Don't take someone else's word for it. It's broken, or it's not. There's no room for 'maybe'.

 

This is happened to me a number of times, and the following causes were to blame:

 

1. water in carb (caused by an open airbox that drew water in while riding in the rain).

2. water in carb (caused by a defective tank cap which leaked).

3. spark plug was loose (absent-minded hence didn't tighten spark plug all the way after servicing), so gases from the combustion were leaking out from the spark plug port. The vibrations damaged the thread.

4. spark plug was not firing properly (fouled due to overly rich carburetion).

5. spark plug was not firing properly (kept using a 1-year old spark plug due to pride and for bragging rights that my bike is so well jetted I can use plugs for years).

6. just plain ol' bad jetting, which is a common compensation by mechanics in Asia.

7. a leak in the extraction system (ie. the exhaust is not tightly/properly fitted; or corrosion may have punctured the expansion chamber or stinger of the exhaust pipe).

 

It might also be loose piston ring, but that will make the bike difficult to start, and it doesn't seem to be one of the issues. If it is the rings, just change them and it'll be fine.

 

In any case, none of the above requires an engine rebuild or changing the block that will cost you a lot of money. However if you feel generous and wish to fatten the coffers of the bike shop you patronise, then it is your prerogative.

 

Isa, tknge, any ideas?

Indeed. And it's painful to think that with the current popularity of Google and the abundance of online dictionaries on the Net, people still can't be bothered to check the correct form of spelling for whichever word they're going to use.

 

P.S. Even the 'Cagiva Mito' thread in this very forum should give one a clear indication of how it's supposed to be spelt. So I still don't understand where the 'babymitto'(ugh) came from. Pulled it out of someone's ass?

 

Besides, there's also the term 'BabyBlade'. And maybe, soon, we'll see 'TeenageBlade', and even 'Grown-upBlade' threads popping up all over this forum!

Alright. But to leave the balance 400ml over a month.. Hmm..

Apart from the suggestions above, for what its worth, check the fuel line too..

Law - Just got back. The stuff ordered from UK is with me. Only 2 sets of balance gear shaft was sent (as opposed to 3). Can spare you one. Call me when convenient for you to pick up. Hopefully once i replace it, my bike can be up and running like new again.

 

Macarena - how was the last track day? Miss me or not? You up for practice this Sunday? Anyone else interested? My preference is to head over on time for the first session, finish up and depart for home before mid-day.

Mi did not go becoz mi sick. Very sick. Bad gastric flu, keep on laosai and laosai and sneeze and fever....now still sick..damn jialat, this time kena one realli powerful one..

This sunday ar? hMmz.. tempting.. okay i tink canz, if i feel okayz after recovery. Keep mi informed okie?

This is bugging me, so I'll be direct - What's your point?

 

I apologise for I can't stand beating around the bush and I've read and re-read your post and I can't seem to see what exactly is the point you are driving at. Is the humidity or air temperature a concern... or something else?

 

Maybe you read an article on engine oil degradation after short-term exposure somewhere, in which case, I am very interested to know about it because I haven't heard of anything like that before.

 

If this is new information, I'd like to know. After all, I'm not some encyclopaedia who knows everything.

 

I've just ran a search on Google, Yahoo, Alta Vista, and Wikipedia, and have found nothing on that, so now you've gotten me a little curious about this.

 

Share please? [state article, author, source and date of publishing if possible]

Thanks!!

To a fellow cynic and skeptic, don't apologise for being anal.

Sure mate. Just let me know how much it is including the shipping and I'll pick it up from you when I'm next in SG. Cash upon collection. Thanks again!

[IZECUBEZ]

Its not that law, I'm trying to find the reason why some of the members here throw out the extra 400ml of gear oil whenever they swap out the old/used oil.

 

I was wondering what effects does it have on keeping the balance 400ml for the next change. Like as though the oil will get mouldy like what happens to bread when being left out for a long time or what not

[lacrimosae]

Hi IZECUBEZ,

 

Found an article of minor relevance, thought it might be of interest to you. Since it is written on diesel engine oil, I will only include excerpts that a relevant.

 

The following is written by Jim Fitch, on the Four Lethal Diesel Engine Oil Contaminants, Machinery Lubrication Magazine, May 2007:

 

Some contaminants are important to monitor and analyze because they are root causes of premature oil degradation and engine failure. Other contaminants are symptomatic of an active failure condition that requires a response other than just an oil change. For instance, seal damage leading to fuel dilution or glycol contamination cannot be remedied by performing an oil change or switching to a better quality lubricant. Such symptom-based contaminants are also root causes that enable new failures to occur. The value of oil analysis in detecting problems early goes without saying.

 

Any one of the contaminants described below is capable of causing premature or even sudden engine failure. I've left dirt contamination off the list because I covered particle-induced engine failures in a previous column. It is worth noting that problems are more pronounced when contamination combos exist, such as high soot load with glycol or high soot load with fuel dilution. There are numerous failure pathways and consequential sequence of events. Thousands of diesel engines fail prematurely each year aided by the presences of glycol, fuel, soot and water in the engine oil.

 

1. Glycol

Glycol enters diesel engine motor oils as a result of defective seals, blown head gaskets, cracked cylinder heads, corrosion damage and cavitation. One study found glycol in 8.6 percent of 100,000 diesel engine samples tested. A separate study of 11,000 long-haul trucks found severe levels of glycol in 1.5 percent of samples and minor amounts of glycol in 16 percent of samples...

2. Fuel Dilution

Frequent starts of an engine, excessive idling and cold running conditions can lead to moderate fuel dilution problems. Severe dilution (excess of two percent) is associated with leakage, fuel injector problems and impaired combustion efficiency. These are symptomatic of serious conditions that cannot be corrected by an oil change. According to one reference, 0.36 percent of total fuel consumption ends up in the crankcase...

 

[removed due to irrelevancy]

 

3. Soot

Soot is a by-product of combustion and exists in all in-service diesel engine motor oils. It reaches the engine by various means of blow-by during engine operation. While the presence of soot is normal and expected for a given number of miles or hours of service on an engine oil, the concentration and state of soot may be abnormal, signaling a problem with the engine and/or a need for an oil change. Following are some issues related to soot contamination:

 

*Combustion efficiency is directly related to the soot generation rate...

 

[removed due to irrelevancy]

 

4. Water

Water is one of the most destructive contaminants in most all lubricants. It attacks additives, induces base oil oxidation and interferes with oil film production. Low levels of water contamination are normal in engine oils. High levels of water ingression merit attention and are rarely correctable by performing an oil change. The following are some additional notes on water contamination:

 

*Long idling in wintertime causes water condensation in crankcase, which leads to loss of base number and corrosive attack on surfaces, oxidation of the oil, etc.

*Emulsified water can mop up dead additives, soot, oxidation products and sludge. When mobilized by flowing oil, these globular pools of sludge can knock out filters and restrict oil flow to bearings, pistons and the valve deck.

*Water sharply increases the corrosive potential of common acids found in motor oil.

 

Failure Development Period

The failure development period can vary considerably for these contaminants. Most sudden-death failures from moderate levels of contamination will usually have one or more aggravating factors (the combo effect). Conversely, massive concentrations of one or more of these contaminants can result in sudden-death failures unaided by an aggravating circumstance. There are dozens of other aggravating factors that can drastically shorten the failure development period as well. More typical is when a moderate problem goes unnoticed and develops over time. This can shorten engine life from say, 750,000 miles to 300,000 miles.

 

The cumulative effect of oil contamination on engine reliability, fuel economy, exhaust stream emissions and maintenance cost of a large fleet is massive. There are no motor oil additives that control the damage caused by these contaminants. Therefore, proactive maintenance and oil analysis are critical strategies to counteract risks.

hmm.. where can i get the air filter element? (call it the mesh or foam or sponge? i dont know x=)

 

about how much will it cost? i may want to change mine.

Orh....

 

Maybe they are worried that the high humidity in SG may contaminate the oil.

 

Oil contaminated by a large quantity of water emulsifies to become a milky, creamy liquid. It loses it's protective, lubricating properties and causes a higher wear rate.

 

But as long as you keep them in the bottle tightly capped, it's not going to be contaminated. Maybe it helps that I keep my oils and spare parts in a large air-tight container with silica gel to remove water vapour.

 

Engine oils are designed and formulated to last as long as possible in the worst engine conditions (high stress, high pressure, high heat, friction and shearing), with as minimal degradation as possible.

 

In fact, we are not allowed to disposed of engine oils (both used and unused leftovers) into our waterways, sewers and soil because without proper chemical processing, these oils will remain in its original form for decades and will never break down. Pour them into the soil, and they will remain there forever unchanged, rendering the contaminated soil toxic.

 

Keeping unused leftover gear oil won't be a problem unless you leave the cap off.

 

So chill, bro, and hoard that oil! The money you save can go to replacing spark plugs, brake pads, tires or even new bling, like digital speedometers. heh heh

Can get a Twinair sponge from WEDA for S$16 I think. Pretty decent, good flow, easy to clean and oil (just get K&N filter oil and cleaner), I love the color too! - KTM Orange! haha!

okay thanks lacri.. i read somewhere about oiling the filter.. and someone used 30w. which is i think engine oil.. wonder if its abit thick ??

okay thanks lacri.. i read somewhere about oiling the filter.. and someone used 30w. which is i think engine oil.. wonder if its abit thick ??

 

Eh? Engine oil? Sounds like a miracle oil!

 

Not only is it formulated for 4-stroke engines, it can be used as gear oil too, and now oiling air filters, and who knows, maybe tomorrow, it will be a healthier substitute for butter!

 

Really! Because it has zero cholesterol, and zero trans fat!

 

(Disclaimer: Improper use of 4-stroke engine oil may damage 2-stroke engines. The above post was for comic relief, not to be taken literally. Please use gear oil for 2-stroke clutch, and filter oil for air filters.

 

The butter substitute is real though. No cholesterol, no trans fat!)

[Jiro]

haha.. butter..=x but 30w used for oiling the filter i did seen somewhere before.. but must squeeze and only allow minimum oil in the filter.. if not the oil will be drawn in during suction of air.

 

well.. so maybe this week im heading down to WEDA to get the filter.. still learning parts by parts to DIY myself (:

[IZECUBEZ]

Now who would do such a thing like putting droplets of water into their oil.. Thx lac..
