2 stroke oil

[antbliss]

hello i am a new member so hi.
i recently went to watch some 2 stroke bikes racing at silvistone,
and they give off a very nice smell,i asked a mechanic at the track
and he said it was castrol r40 that gives that nice smell.
but then i asked someone els there and they said its silkolene pro 2.
im wanting to know what one is it that smells so nice as id like to get some for my kx 100,
i know it will be abit of a wast on a mx bike but i want to maintain my bike as best i can,and also my grandad likes the smell too

They might have been running race fuel, which tends to smell quite nice when combusted.
To be honest though, any 2 stroke smells pretty good.

[antbliss]

no they were running normal fuel,
i no 2 smokes smell alryt as it is but i just like the nice caster smell but dont no what oil it is i need.
i just want my bike to have that nice smell and be different from all the other 2 stroke mx bikes

I know my freind runs 2 stroke, that smells of strawberrys. Really strong :L I dont know if its just coincidence, or if they are 'flavoured' but have you tried google? I can find out what oil hes using if that helps?

I've been wondering this myself as my 2-stroke doesnt smell like one and I wish it did. Mine doesnt smell of anything or even smoke that much except on start up! Damn modern oils!!!

Bought some expensive 2t oil in halfords- not sure what it was because my oil tank lasts about 500 miles, thought is was Castrol something but it doesnt smell

Castrol TTS doesn't smell as much as some oils do. Usually the really smelly ones are vegetable based oils like Castrol R etc,

yeah its castrol r40 iv been told but it says Never mix Castrol R40 with mineral based or synthetic crankcase oils and i dont understand that as the gear box is separate

isnt tts a scooter oil?if not are try that
so if i was to use castrol r40 would i have to change my gear box oil?
i wont be mixing 2stroke oils as its pre mix so i just put the oil in with the petrol
but by crankase oil dose it mean gearbox oil as i always thought they were separate thats why the gearbox has gear box oil in and then the petrol has 2 stroke in,
so i carnt see what it means

You can use Castrol R40 as a gearbox oil, use it in my TZ, that will be why they say don't mix it with other gearbox oil.

Most people I Know use Castrol 747 or XR77 in their fuel, both smell nice.
Another good one is Silkolene pro 2. These are all pre-mix only, put them through an injector system and you WILL f**k it up and probably seize the bike to boot.

The best thing for your mx bike is a fully synthetic race 2 stroke oil,
The reason I use Castol 747 and R40 is because that's what the bikes always had and it has been reliable. A change to something else would mean a very thorough clean out.

I didnt know about pre-mix and injector 2 stroke oils? Guess I got lucky running Castrol TTL through it. Why would their still be many premix versions about? My bike was made in 1980 and uses an injector, surely the H100a cant have been at the peak of technology

well my kx 100 is 1989 so an old bike,
if i run it out of fuel,so theres no old oil left(silkolene comp 2)

then can i mix the correct mix of r40 in with my petrol
and i already use 10w40 as gearbox oil and will continue to use that as its cheap and if i put r40 in as gearbox oil its to expensive

i had a look at 747 and xr77 and they dont sound what i need as it says for multi cylinder engines at as low as 40-1,atm im running 50-1,i was wondering could i get castrol r40 and use along side of my current oil silkolene comp 2 by just adding a cap full of r40 to make it smell nice but still using my normal mix of silkolene
