Otischop Posted December 21, 2020 Report Share Posted December 21, 2020 Hi all, Brand new to the trials world and looking forward to getting out on my "New to me" 2016 Beta Evo 250. So just two things, probably mentioned loads here already but really would like some reassurance on Petrol/Oil Ratio, some say this, some say that. Just don't want to wreck it before I start. So 1 litre of Petrol with 20ml of Oil? that be fine or maybe 25ml? Just not sure. Also I noticed that the rear brake light didn't come on, opened up the cover and to my surprise no bulb, not even the housing that would hold it or wiring... Is that right for this bike? Thanks, Looking forward to asking more dumb questions as I venture into the world of 2 Strokes :) Otis. Quote Link to comment Share on other sites More sharing options...

darrensn Posted December 21, 2020 Report Share Posted December 21, 2020 Had 5 betas and ran them all at 75:1 1000 ml super unleaded fuel : 13 ml two stroke oil. They all ran clean with no issues what so ever. 1 Quote Link to comment Share on other sites More sharing options...

Seams so many use the 5 litre ratio as the guide. Ta, Quote Link to comment Share on other sites More sharing options...
huski Posted December 22, 2020 Report Share Posted December 22, 2020 If you use super unleaded it doesn't go off,just mix up 5 litres and use it when you want 1 Quote Link to comment Share on other sites More sharing options...
totty79 Posted December 22, 2020 Report Share Posted December 22, 2020 5L is 2 to 3 trials or practice sessions, and it'll easily keep over 3 months. Anything in the range of 70 to 80ml of Synthetic 2 stroke oil is fine, best to pick a number and stick to it. Either trials specific or something with a low burning point ideally not a "racing" oil or you may get spooge. Take a look at the clutch thread particularly the shim and gearbox oil recommendations, a dragging clutch can really hold back your learning. 1 Quote Link to comment Share on other sites More sharing options...

Ta, i always do the 5 ltr then just fill up the bike when i go out .sometimes its about 6 months before its used up 1 Quote Link to comment Share on other sites More sharing options...
pindie Posted December 22, 2020 Report Share Posted December 22, 2020 (edited) Get yourself a 5 litre can of Exol Optima fully synthetic 2t. It’s usually around £30. Should be on eBay. It’ll last a life time. It’s excellent clean burning oil that works perfect in trials bikes or any 2t in my experience.
