125CC performance Scooter oil?

[ktk_ace]

HI BITOG,

newbie here, first time posting a thread, heres my scooter setup :

Yamaha Cygnus X 4V air cooled 124cc displacement scooter.

operation range 5000-9000RPM (aveage 6-8000 RPM ,aftermarket CVT kit)

ambient temps:

25-35 deg C summer

10-25 deg c winter

dry clutch

no oil filter

mostly city stop and go riding (1-30km)
.

Have used before MX4T 10W40 , castrol edge 5W50, Fina Formula racing 5W50 and motul 300V 4T 5W40 on my setup .

looking for a blend of price , performance and durability .

most of my oils get fuel diluted within 1000KM , with the exception of MX4T(changed at 1250KM). 300V starts to reek of gas at around 1250KM/3 months (1 month in summer storage) too.

Also using FP60 as fuel additive, 10 ML per 6 litres.

should I stick to MX4T (9.5 USD)or is tere any other recommendations? Amsoil sells here but its expensive (12USD) , worth the switch?

wanna give GC a try, but alas, i cant find it here in Taiwan.

I forgot to add that :

it only produces 10.3 HP so i took my chances and posted it in the small engine area.

sumps are NOT shared, no wet clutch.

mobil silver cap 15W50 is too thick, it makes the throttle response "sluggy" .

factory recommendation is 20W40 oil (eh!?)

I have a Suzuki Viva R that I run Bel Ray EXS 10W50 every 5000Km for the last 45,000Km. I also have a Yamaha LC135 that runs on Motul E-tech 100 10w40 for the last 12,000Km with a 3000Km OCI. Both of my bikes are wet clutch and the oil held up fine. If I was you I would just run Castrol 20w40 dino oil and change it every month or 500Km which ever comes first. I know a lot of people that do this and their engines last over 100,000Km. I would also look at tuning the carburetor to reduce the fuel dilution issue.

 

[tdi-rick]

If the the fuel dilution is that bad I'd be doing what azsyn suggests and run a dino oil with frequent changes too, and I run syn oils in almost everything I use and operate.
Then I'd be looking into why your fuel dilution is so bad, I'm guessing lots of short trips of only a couple of km or so ?

 

[oil_spaz]

With fuel dilution an issue, I'd run whatever reasonably priced dino 15w40 HDEO is available in your area. Change at 1000 miles.

I've run 15w40 in my Yamaha Vino 125 since new---3000 miles. Probably the same engine.

 

[ktk_ace]

as i said, my scoot hates dino oil, it makes the throttle response slow as [censored].

tried the chevron 10W40 a year ago and dumped the [censored] thing within 50KM's.

I already said i make short frequent trips and what i an looking for is a blend of performance and durability, dino oil's performance is totally unsatisfactory.

 

[azsynthetic]

Dino oil is perfectly fine for the bike. It is your driving style and your expectation of the little 125cc motor are the problems. That little 125 motor is not designed for constant 6-8000 rpm usage. The engine redlined under 9000 rpm. If money is no object then I recommend Maxima or Bel Ray 10W50 full synthetic.

 

[ktk_ace]

"looking for a blend of price , performance and durability ."

performance, i doubt dino oil can give me any. semi-syn maybe yes.

if all i want is durability, i would have used the Mobil 15W50 ages ago.

I live in a city, filtering between cars is very demanding on the whole setup , a 0.5 second advantage is very crucial for every car that i pass and not all oils meets my revving requirements.

I would love a bigger bike but it is pretty much useless in cities, its way too big to filter around.

I think its your misunderstanding that i expect too much from my scooter and blame it on my riding style while you have no idea how hectic city riding is.

nope , not same engine, that one's a 2/3V while mines a 4V .

beside the carb tuning, any way to get around the fuel dilution problem?

vent the oil after long distance riding?

 

[oil_spaz]

The short trips are the problem assuming the carb is adjusted OK. I'm not even sure an extended trip once a week would boil the fuel off once it gets in the oil. Venting the oil may help.

Tough dilemma. You may be stuck with just doing frequent oil changes with whatever oil performs the best for you.

 

[greenaccord02]

If I were you, I'd run Rotella 5W-40 and put a TC-W3 approved 2T oil in the gas at a 300:1 ratio. You might be able to get more out of it depending on conditions and the ratio of 2T in the gas.

 

[ktk_ace]

so if your assumption is right, i might only have frequent oil changes to depend on.

2T oil in my 4T gas? thats new but are you sure? Looks very risky to me and finding 2T oil with that spec might be a problem in my area too.

Im currently running very thick concentrations of FP60 in my gas, around 1.5-2X the recommendation .

Actually fairly common for a few of us on here, I've used Castrol TTS (now Power 1 Racing TTS) in the past.

I use Redline RL2 diesel additive in diesel fuel which uses a fair dollop of their two stroke oil in it, but I'd probably stick with FP60.

The whole situation with your bike is unsatisfactory, what's the factories response to any questions about this ?
If you can't get any satisfaction from them, I'd be dropping Terry Dyson a line for help.
I'm overseas too and use Terry, he works by email.

err, my scooter is a 4 stroke engine that technically doesnt need 2t oil in my gas or so the factory manual says...

I dont mind trying out new stuff as long as its not too outrageous thou... XD

whos Terry Dyson?

Modding the CVT for acceleratin voids my warranty already and the warranty period is long over (1 yr VS my scooters 1.5 year life )

You misunderstand the performance envelope of your little scooter. Your scooter is not designed for 9000rpm usage nor is it designed for 6-8000rpm average usage. Riding in Taiwan is no different than in Vietnam or Thailand or Malaysia and I have done them all. A 0.5 second gain in a scooter means very little in distance and safety. Weaving between cars at scooter speed is asking for a death penalty, been there done that and lost a few friends also. My current ride in Vietnam when I am in country is a Yamaha Exciter 135 LC4V (discretely modified to keep the police from making money from me). The engine now red lines at 10,000rpm with a Rextor CDI and the best I can do is a GPS verified 130km/h. Normal city speed for me is 40-60km/h and at this speed the engine has enough juice left for me to make a safe pass. You can check the spec but I can guarantee you that your bike is a lot slower than mine.

Im here to ask about oil, not brag about my scooter.

Anyone on the 2T > 4T fuel tank issue?

 

[greenaccord02]

Run it at about 500:1 and you're good to go. You won't regret it and neither will your machine.

And yet you refuse to listen to advise about oil for your scooter. Read post #1606402 above about real life experience and recommendation or use the scooter the way it was meant to be used. Your inquiry is about how you can abuse your little scooter and get away with it. Why do you think your oil is reeked of gas? Why do you want to compound your problem by running 2T in your gas? Good luck.

Good luck to you too.
