Just wonderd what others use in thier petrol mix and how many cc's/ml to a litre you add.I have been mixing 200cc's to 5 litres for my 414 Montesa Cappra.

[Montynut]

Yep 25:1 (200ml - 5lt) Castrol TTS oil 98 Caltex fuel in all my Monties & KTM. VG414, VF250, VB360 & VR250, '84 KTM MXC250

32:1 in the trials bikes 349, 242, TY250

Hey Montynut,

its a personal choice, but out of interest.

i used to use TTS for 20+ years till 2005 then i switched to Motorex when i bought a KTM300, i now run it in all 4 of my 2st.  i wouldn't go back, is there any reason you still prefer TTS or just that its tried and proven in your bikes?

[Montynut]

Tried and proven really never had any problems with it in all the years and relatively inexpensive. Easy to get and everytime I pull the bikes down everything is clean and well lubricated.

Lastly never really thought about changing.

There was a thread on here about a year ago and went on for 20 pages or so but was very informative. From that I also could see no reason to change particularly in the old bikes. Now if I bought a mdern KTM, Husky, Gas Gas 300 or one of the modern Gasser Trials bikes then maybe (well probably) I would change as well.

The previous owner of the '84 KTM was running TTS at 30:1 but I just stick to 25:1 its is easier

yep fair call, why change when you have no issues.

i was the same. the only issue i had with TTS was the power valves in my 86' CR250 used to gum up a bit. i always ran 40:1 TTS.

i have noticed now i use motorex that they rev cleaner much quicker on cold start with the modern oil.

if i didn't buy the KTM i would still be using it too as i don't change much. i tried it to keep my warranty  and used up the TTS and then tried it in other bikes and just kept using it.
