Question about 1986 Honda NS 250 R

1 Answer

Unsure about gas setup

Hey .. i just picked up a honda ns250r 1984 .. can you tell me if the gas mixture is premixed before i put it in the tank or will it mix itself... ps it is two stroke..and what oil do i use?... That was some very good info......I too have a 86. It has been re-sprayed before I got it but the front forks are red, so maybe...maybe was a brand new import??
Anyway, Im lazy & new to bikes so Im going to have to ask a really stupid question....I need to top up my gear box (?) oil (its on the right side but Im meaning where the kick start is) I use any old tranny oil or what?
Cheers for your help chief.........

Hi and welcome to FixYa,

It would appear that there are 2 questions/users on this post. Still, on your bike, normally, the tank hold plain gas, not premixed. The 2-stroke oil (2T) has its own reservoir attached to the right side, on the frame. The filler would be exposed and relatively easy to access and fill up.

On the Gearbox oil for 2-stroke engines with a wet clutch, SAE 10W40 is the standard.

Good luck and Thank you for using FixYa.

Oil to fuel ratio

Many of the 2 cycle motors use a 40:1 gas to oil mix. There should be a label on the motor that tells what the mixture should be. You also can buy a premixed container that has the gas ad oil mix all in one can. Just pour it in the gas tank, then pull the starter cord.

What is the correct mixture for eb7000 blower? it ran perfect until i put in a mixture of all ratio oil mix gallon of gas to one oil will run it all... now it boggs out and sputters then stalls...

50:1 is the correct mixture. Every company has an oil they would perfer you use. Namely, the one they make. I would imagine that if it ran perfect before you put that premix in there, the premix is your problem, assuming no one "borrowed" it and straight gassed it. It also sounds like once it gets warmed up, it begins to fail. I would do a compression test once it gets warmed up. Also, you could pull the spark plug, grab a flashlight, and see if you notice any scoring on the cylinder.
Here is a link for the manual, in case you lost yours.

Gas oil mixture

The header says that it is an electric saw which would only require bar oil. A 2-stroke gas engine, however, does require fuel mixed with a modern saw oil at 40:1 ratio plus bar/chain oil in it's own tank as well. Always premix the fuel and oil in a separate can and shake well even before filling the saw. Hope this helps!

How do I remove the false gas tank on a 1984 honda goldwing

You can pick up a complete owners/service manual as well as the parts manual on cd. I got mine for my GL1100, then when I upgraded to my GL1200, I picked up another set from the same person.
Contact Wanda G at I believe she still sells the cd's for around $7.00 including the shipping anywhere in the US.
When I got mine, she included both the owners/service manual and the parts manual. Pretty big to download, at around 200mb.
Manuals are good enough, I just rebuilt my engine, and all 4 carbs and I'm no mechanic.

Unsure about gas setup

 It has auto lube, the oil bottle is under the seat. Use any full synthetic 2stroke oil. Some bikes may have been modified to run on premix and this would be worth getting checked out by a bike shop. If its been sitting for a while its a good idea to put a tank full of 40/1 premix through it anyway.   Look after your bike, they are becoming very rare and many engine parts are no longer available. The NS was one of Honda's premium products, hence the "R". It had hand matched engine parts and was very expensive to produce.  There were only 35 new red/white bikes imported  into NZ in 1986, removed from the Japanese market  to make way for the NSR. All other NS's imported, blue/white, were second hand imports.   I have had mine from new and it was the first sold in NZ, prepaid before it landed. I have a factory Honda manual for the NS250R. I'm happy to help you with tech info you need. Just post your Q.
