Two Stroke Engines & Refuelling

they break down if you look at them the wrong way, forget about compression, and don't worry about being a noob, a 2 stroke will make you a mechanic after a week anyway.

Usually the oil and petrol are kept in seperate reservoirs and mixed automatically by the bike.

If you must go 2 stroke, get an Rs-125 Aprilia or something. NEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!!!!!!!!!

Judging by your other thread asking which bike is best.

The reason i chose the cbr250rr over the slighty better power to weight ratio 2strokes is not only are they more reliable but also far less maintenance.

You will be pulling apart a 2 stroke twice as much. But if you have the time/patience/money/dedication and another form of transport go for the 2stroke, it will be a great leaning experence.

I would always take the cbr on the long jurneys where you need to be somewhere but you can cancel all appointment riding a 2stroke!
That said, they are awesome fun!:headbang:

the nsr oil res will last about 2-3 tanks so no, you dont need to pour oil everytime.
bottle of oil will cost as low as $9 for a litre and will last about 5-6 tanks of fuel.....

you dont need to do oil changes on the two strokes, only for the gear oil.........

id go the cbr........

Yeah, 2 strokes are "fun" but that fun comes with a price. 4 strokes, namely the cibblet are much more fun with a lot less time involved.

2 strokes make great alternate transport

Alot of 2T's are unreliable comments here.. I say BS and just that you need a little more knowledge, get your jetting right and they will last.. Let's not forget people, there are less moving parts in a 2T and that equates to less problems that can go wrong, potentially less money and easier to work on when something does go wrong..

Considering it takes 2.5 hrs to do a full top end rebuild on a 250cc 2T, that is not very long the bike will be off the road for maintanence.. How's that compare to doing a top end rebuild on a 4T??

Don't go 125 or 150 2T you will be disapointed get a 250 2T..
However, 2T's require a certain riding technique for the road, for ease and pure lazyness go a 4T..

the 250 smokers usually arent lams approved though if you are still on l's....

Also, as far as the OP...

Some run on premix, some have an oil pump. The reason they have oil in the fuel is to lubricate as far as I know. They are much more simple in ways than 4 strokes.

What is the LAMS limit??
I know for a fact the NSR250 is 45 ponies,std..

However by simply cutting 1 wire and splicing it into another wire you will get another 8hp or so.. Then if you wanted to spend another 2G's you could get it up to around 70 RWHP..[hr]

The NSR150 has a 1.2L oil res tank, an owner should be able to get about 8-10 tanks per top up..

The oil in the fuel is to lubricate the engines moving parts, get your jetting correct and it will last..

The NSR, RGV and RS are specifically excluded from LAMS. The power/weight limits only apply above 250cc. All bikes <250cc are LAMS by default, apart from the exceptions.
