SBF Kymco Downtown 125/200/300/350i Cafe 2013

Yes, agreed to a certain extend.

EO don't recommend to use 2T as the grade is usually too thin like 20. I am still confuse as to why new cars can run 30 oil. Less drag, good fuel consumption but protection also good too it seems.

 

As for smaller bike don't need to use good oil is a matter of preference and application.

Most small 4T bike also subject to the same torture as a bigger cc bikes.

 

If one uses mineral oil and changes regularly is as good as using synthetic.

 

Now the question is this scooter 125cc although small is subjected to high rpm constantly say 6000rpm to 7000rpm average riding. If it's a normal 2B motorcycle with gears will have lower rpm with same average road speed. In another words, it's about protection not performance. I agree that it will not yield better performance but better protection.

As for spark plugs and fuel, I agree that it's not about better performance also.

For spark plugs, I use iridium for efficiency and longer service interval.

 

Leaving everything stock is the best for reliability.

So the focus here is if it's about performance than no point.

If it's about better protection and longer service interval, then it's well worth it.

 

Ha ha, after explaining, I now understand why I did all these things.

 

hahas, yea..0-o..my 2t actually refers to my 2 stroke bike ehs..bought from spc and bike shop..really can feel difference..but..spc the nice nicer..lavender de..

[velocity325]

Oh well. So I shall stick to MS first then.

 

See how's their oil. If good, then I shall stick to the brand. Or else, I'll try OWS the 2nd time round.

 

actually you can just visit a bike shop and save the hassle of thinking where to dispose the old EO..won't want a nea officer walking past you seeing the oil into the drain..it can really be a hazard..bike shop normally have simple packages like EO and SP as low as 12 dollar to fifty over dollar for a 2b bike that normally requires less than 1L of EO..

[velocity325]

btw parotae, you've any recommendations in mind, which type of grade of EO should i use if i do drag my gears that cause EO to leak a little by a little..?

[parotae]

Wah lavender smell?! Wait fall asleep ha ha. Lavender smell aids in relaxing or sleeping.

 

I guess you ride a 2 stroker. Don't think oil will stop the leak if there is a leak already.

Must find te cause of the leak or where the leak is from. Usually oil seal or a loose joint for 2t oil.

Thicker oil can slow the leak. 2t (20)oil very thin thus flow easier than normal 40 oil. 2t bike cannot use normal engine oil, too thick, cannot flow and mix properly in the carburetor.

Higher rpm creates higher internal pressure forcing the oil out through already weaken, blown, harden oil seal.

 

Is yours a 2T bike.

What rating oil you use for your gearbox?

err, yea mine is a 2t bike..cause i visited my mechanic..and also read up on the internet..leaking of EO from the exhaust most bottom part closet to the ground is due to high revv which is kinda healthy for the engine..but i find it funny..and also sometimes 2t when my 2t is topped up too full..so was actually thinking issit because my EO is too lean thats why..

[parotae]

Too much 2T. You open the pump too much. 2t ratio should be 1:50 I think.

Meaning 1 bottle 2t 1 liter to 50litre of fuel. If 1:25 then 1 liter add to 25 liter of fuel.

If your bike recommend 1:50 mixture than for every 10 liter of petrol you must mix 200ml of 2t.

That is if you mix it with petrol in tank.

 

If you use 2t pump then you must estimate that for every 5 times you pump with 10 liters petrol each time, your 2t must use only 1 litre. If before 5 times fuel pump you put 1 liter 2t then your 2t pump must turn down smaller.

 

In this case of the oil from your exhaust, it's normal. The extra oil that cannot burn will be collected at the lowest point of the exhaust. The oil got no where to go so leak out. If your exhaust is very well seal then all the oil will be collected in the muffler until the bike no power(exaggerated here ha ha)and the oil will spray out from the exhaust.

hi all...

may i know whats the rough fc of the downtown 300i?

the underseat can fit 2 FF?

any idea the current price?

[topgearalwaysrock]

The DT300 now should be $12k OTR.... w/out Ins though.

 

and yes, underseat can store 2 FF if u squeeze lah.... Haha

 

But 2 half face definitely no problems.

 

FC about 27-30km/L....

 

I'm riding the DT125 though, am getting 30-35km/L....

WOW, THANKS! omg, what you riding?

[paithorn]

I think 40 will be better also but since recommended 5W50, I better stick to it until I know why Kymco recommend 5W50.

 

They recommended 5W-50? also you know why? Can share with me?

[topgearalwaysrock]

Or is it because those are the only type of oil they carry?? Lol!

[paithorn]

I meant Kymco - Mechanics can tell me all they want, I never listen....

[velocity325]

I meant Kymco - Mechanics can tell me all they want, I never listen....

 

positive mindset..strong determination..prevents mech from doing this and that ending up to pre mature failure of certain parts!

[topgearalwaysrock]

So how? Haha.

 

Best is to service the bike on our own??

[paithorn]

I meant Kymco - Mechanics can tell me all they want, I never listen....

 

I meant KYMCO recommend 5W-50? Where did parotae read this? Can share with me?

 

 

Mechanics in Singapore generally I dun trust.

[parotae]

I read it in the owner's manual.

They also mention if this rating oil is not available.

The others can also be use.

There is a graph/picture showing the range of oil that can be used.

[parotae]

They recommended 5W-50? also you know why? Can share with me?

 

I don't know why? Ha ha still looking for answer. I asked a mechanic friend ( ha ha can you trust him) that the reason for using such thick oil could be because of vibration. Vibration also causes wear. Thicker oil act as a damper and cooling.

[parotae]

WOW, THANKS! omg, what you riding?

 

Use to ride Gilera Runner SP180 2 stroker.

Now riding Downtown 300.

awww..two stroker kinda fun..heyss..next time if i need any help i pm your ar :D

[parotae]

If I can help, sure no problem ha ha.

[synman]

FUCH.

 

Filter can buy at $15. No point changing filter when you not changing the oil. You contaminating the filter

 

Try the 5W-40. The 15W-50 is too "thick" for Singapore. You will feel less power for your vehicles. My personal "feel" I am no expert.

 

Agree man, it is all about preferences at the end of the day. If I feel I'm happy with the current EO (Moty's), then I won't really bother changing

to another one plus the value I got for it is really reasonable.

[synman]

Just now ask my friend why my old skipper recommend 5w40 but Kymco recommend 5w50.

 

He says could be due to vibration to prevent premature wear.

Hmmm... Till a certain extend, sounds credible.

 

Thicker oil do act as a damper for noise and vibration I guess.

 

But they also recommend others if 5w-50 is not available.

 

They also said they are going to resolve the vibration issue too.....

 

Actually, 10w-40/50 should be good enough in Singapore for a new bike.

 

Was waiting to try the 10w-50 from Moty's which is for performance bike, but Firesaint don't have any

at the moment.

Dr. Pulley HiT clutch on it's way from Taiwan, I had enough from the stock clutch.

From what I've red the clutch I am getting comes with 6 springs which makes it special, the tricky part is to get the weights right, it should come with some spare springs. Unfortunately there is not much information on what is the best combination. I can see that on one of the forums linked by Parotae there are Nikita owners that have installed it but Unfortunatly is in Chinese .

 

If anyone has come accross experiences with this clutch I will be really grateful if you can let me know what will be the best combination of springs to get the most out of the clutch and get rid of the clutch slippage when pulling away from stand still.

 

Thanks!!!

[parotae]

Hi Juan, wow 6 springs.

 

I guess you have to fix it first to see at what rpm it engages.

 

If it engages at 3000rpm with vibration ( just an assumption)

 

Then may need stronger springs to get it to 4000rpm to engage and test again.

 

It really depends on your preference.

 

I've read on the Taiwan web site about the shop installing the clutches for different owners and diffferent owners have their own preference on the engagement/biting point. Some like higher some like lower.

 

So fix to see how the clutch behaves and decide if you want it higher or lower. Hopefully there's no adjustment needed.

 

Will keep a look out for hit clutch adjustment/settings.

[parotae]

This should be an interesting read about clutches. (Dr pulley Hit Clutch but same theory as conventional clutches)
