Adding little 2T oil into fuel tank for 4-stroke bike and feel the smoothness

[CSV]

update on fuel consumption.

 

this time mileage without 2t, but with new EO, air filter, spark plug and retunning of carb by ah chong = 35km/l

 

but the bike power feels slightly less than before. harder to reach 110km and noisier.

 

Today, with fresh tank of Ron 92 and 2t, the bike felt slightly more powerful but i am not too sure if its the 2t or because the weather was cooling, therefore lower engine temperature.

[Hydher]

Dont know if i should cont using 2t. my plugs have never looked this bad before hahaha.

[CSV]

@Hydher, try a dry run without 2t for maybe 2k km. then check your sparkplug.

 

if its still the lower cyclinder that are fouling, could mean engine blowby. thats the best way to find out if 2t is really causing the fouling.

@Hydher

 

Agreed. You empty your fuel tank completely first, as in dont ride with the petrol, go and store it in a container or something, then change new plugs and then ride for a few full tank's worth. Then see whether your plugs are getting better. Your plugs look bad.

[Hydher]

Definitely because of the 2t. I know my bike best (:

[crazydj]

Then why you put the 2T inside the tank in the first place? Haha.

[Hydher]

Because like some things, it feels awesome when its inside.

You know its wrong but its addictive.

[naim]

hahaha! maybe u try to tune ur carb? seems too rich... maybe lean out the mixture abit... but like the others say, try a tank w/o 2t 1st la..

[crazydj]

Aiya, i predicted that this would happen to someone eventually. You know the condition of your spark plugs can tell you alot about your bike. My theory of the 2T adding to the incomplete combustion equation and all that crap. Haha.

 

But seriously, stop using that crap, get new plugs and run it normally again. Later become even worse piston jam and all that crap la huh. Haha.

[Limsteel]

If due to 2t it should happen to all the plugs not 1 sided. This is the vtwin carb not sync or unbalanced. Send to workshop for a good tune should solve the issue. Bike not using 2T can also have foul plugs due to many other reason. Pinning the fault to 2T, too bias.

[crazydj]

He said he knew his bike best... Oh well...

[ChaoPuzzy1968]

Here's my plugs after 5k of 2t usage.

Looks a little fouled to me on my rear vtwin cylinders. Top 2 are good.

My butt's dyno tells me there's a world of difference.

Well done and Thanks for the picture...so where to meet up and pass you the ten dollars for your effort?

[Hydher]

hahahaha. Wow free dough! Thanks but dont need. hehehe Just a snap from my routine maintenance (:

Well, when i changed my plugs at 5k the previous times, i'm pretty sure it wasnt as fouled.

 

To naim, tuning of a Vtwin is different.

Dont know about running rich but my fc improved from hovering from 17-22 (3L of bardahl oil when engine sump after filter change is 2.25)

to 27-29 after my previous service of Rock oil fully syn, new filter and plugs and 2t addition..

 

using royal purple now and i just got 26.. but this kinda figures gotta get mean figures.

 

like what limsteel said, could be a biased test. Could be plentiful of other reasons

Thanks ... perhaps my top cylinders are better balanced. Will look into it.

Well, if you guys can wait 3 months till another change (without 2t) then standby.......

TC-W3 oil is very popular as an fuel additives. check up this oil. Amsoil meet great oil. cost only $14 at Mxtradings. should be able to keep things clean.

 

i just finish 3 tank of petrol with Redline SI-1 which contain a good dose of polyetheramine(PEA) aka Techron. now i trying marvel mystery oil which act as UCL although not as good as 2T oil but design to clean the system as well. it a compromise between 2T excellent lubricating yet run clean. popular stuff over BITOG.

[ChaoPuzzy1968]

just pass inspection for the dr 200 will try and document usage of 2t here

[Doomxxx]

One thing for sure is mileage increase and smoother shifting gear.

That from my own experiment. For plug maybe slightly darker due to oil.

So far go good only that not everytime add 2T because too trouble some to add 2T everytime pump petrol.

[Isopropyl]

i use a little squeeze bottle. it dispense about 1ml per second. work well, fast and clean compare to the cough syrup bottle i used to add additive with. i will have given up using fuel additve if not because of it. my bike only hold 4 litres of petrol so it such a blessing to me.

wow it work out to about 20 min 1 ltre into the tank?

[Isopropyl]

wow it work out to about 20 min 1 ltre into the tank?

 

i only need 10ml of additive so it take 10sec. compare to using a bottle, i have to keep rechecking how much have i pour which take much longer. not to mention oily hand and bottle:sian: it work just great my usage:thumb:

 

1 litres of addtives??? what the hell have you been ridingo_O batcycle???

INITIAL REPORT

http://img.tapatalk.com/77387390-c507-aec2.jpghttp://img.tapatalk.com/77387390-c520-aebc.jpg

some light powder coating on the rim of the plug

 

six months of local riding without 2t abt 1k km a mth to about total of 6k km fc is 35-40km/l on an aver speed of 60-70km/hrs

 

normally 2 up of 160kg

 

bike use will be suzuki dr 200 old school

 

mixture will be at abt 5ml/ litte

 

next report will be on every 1 mth or 1k km later

[CSV]

interesting, light coating could be the carbon from 2t as that is where the fuel mixture is combusted.

ChaoPuzzy1968 showed the light powder coated spark plug before using 2t.

my bad , correct and thks

[stsoh]

incorrect, white coat on the spark plug electrode means engine runs lean.

2t oil burnt ash-less thus shouldn't be any residue.

brown or tan color if carb tune a/f mix correctly.

ash-less on your 2T oil bottle mean there are no heavy metal detergent that burn to a heavy metal salt(ash) to be use for engine with lower combusion temperature. it does not mean there will be no residue after burning. Residue and ash are quite 2 different things as it definition can be quite board.
