2 stroke autolube - What is out there?
Permalink  

If one was to be considering a 2 stoke green lane machine, which wouldn't require premixing of oil and petrol..... what would be one's options?

Old, new, cheap, expensive...all considered.

All suggestions welcomed smile

I got this from CLICK HERE

Oil Injected Dirt Bikes

The first was Yamaha's DT line beginning in 1968 and running through 2008.

The DTs used Yamaha's trademark AutoLube. Jr. dirt bikes or "mini-bikes" picked up the system out of convenience and insurance that a kid wouldn't forget to premix the fuel and promptly seize the engine. In addition to the small displacement Yamaha DTs, Yamaha's PW series 50 cc and 80 cc are oil-injected and still manufactured today.

For a fairly contemporary, adult-sized dirt bike, Austrian manufacturer KTM used auto-lube in some of their EXC200s, though it's not an option on new EXCs and you have to check the specific model, as some came with auto-lube and some didn't, even in the same year.

If you want a brand new adult-sized dirtbike, Kawasaki's KDX 200 series is a well-reviewed dirt bike and it still uses auto-lube.

Honestly it's not too much of a ball ache if you have an oil bottle marked up with different mix ratios, why narrow your options of bike ?

See link to mixing chart (modern machinery), the most important part is to know what RATIO OIL TO PETROL you engine runs on.

I just know nothing about owning/running a 2 stroke. Is it a case of adding oil everytime you put petrol in the bike, and obviously dependent on how many litres of petrol are put in? How much woudl I be looking at for say 1L of 2 stroke oil?

I still don't get it.what happens if u need to top up when you're on a ride? Do u just add some oil from your tube in your bag to the petrol in the tank?

I run the GasGas @ 50-1, the bottle I have is marked in 1 litre amounts and holds enough oil for 12 litres of fuel.

put 3 litres of fuel in = 3 marks on the bottle

Spot on, that makes more sense. I agree I could live with that. I guess with a 2 stroke you're just more limited on single trip distance with only a small tube of oil. I don't envisage doing anymore than 100 miles total in a day though whatever I was doing.

I have a KDX220 that runs pre-mix and a 220SR that has auto-lube.

Running a pre-mix petrol/oil ratio of 40:1 means for every litre of petrol, I have to put in 25ml of two-stroke oil.

I don't want to carry a large bottle of oil, and setting off with a full petrol tank means I'll only need to splash in 4 or 6 litres of fuel during a full days ride, so I use 100ml bottles, which don't take up much space in my Camelbak or tail bag.

Not knowing what type of rider you are general a auto lubed engine is down on power compared to a mix-it jobbee thats not altergether a bad thing as as again generaly auto lubes motors develop smooth power and are generaly older scoots ? the modern KTM 250exc etc can be tune very easly to have high or low power runs cleaner and develops more bhp to play with +tune plus sus brakes will be better and the bike will be lighter of course ? yer pays yer money and takes your choice best of luck lost

 My 2T 250 EXC will do about 80-100 miles before I hit reserve (11L tank). My bike runs on 50/1 so I need 100ml oil for 5L fuel.

Therefore with my little 100ml tub I have a 'range' of about 140 miles which is more than enough for a days ride (as I have had enough well before that wink)

It's never been an issue in 3000+ miles smile

Thanks for all your input you've made me a lot more comfortable about considering a 2t for my next bike. It won't be buying for another 6 months or so but my requirements will be something light, and not all 'top end'. I'm a relatively novice green laner so could use a bike with lets say 'forgiving' power delivery. Having said that i still want something which is going to put a grin on my face!

I love my DRZ but I do find it a bit rotund on the trails. I'm a short arse too which is a considertion with anything I look at. I've gotten by on the DRZ by getting a Suzuki gel seat which is about 1.5" lower than stock.

Taking the GasGas (ec300) down Bodmin for a new piston / rings - peace of mind only, bound to have 2012 gassers in the show room........
