How To Maintain a 2 Stroke ???

[Stuster]

Hi all,

I have just baught my first crosser style bike, I have very briefly owned 2 strokes in the past but never really kept one for longer than a month or so.

I have recently baught a Yamaha DT 125 (87) and am planning on keeping it as i have spent quiet a bit getting it road worthy....

I am looking for some tips on how to run the bike properly and keep it running nicley. Seems a daft questen i no but i hear that the 2 strokes can be a pain if not maintained properly.

Thanks in advance for reading this post and your replys

Keep it topped up with the best oil 2 stroke oil. I'd recommend Castrol e.t.c and try and avoid your supermarket branded oil.

Every few thousand miles its advisable to "de-coke" the engine,
eg pull the head off remove all the carbon buildup on the piston and around the rings, and also the head.

De-coking the exhaust is always advisable at the same time,
either by burning the carbon out or chemically removing it with a caustic soda mix.

And thats all the maintenance you'll probably need to do.

I have a 2 stroke and personally I would rather have a 4 stroke, but hey that's just my opinion.

the dt is probably one of the most/more reliable 2t's (as compared to rs's,mitos etc) & dont really need rebuilding that often, so as above : keep it topped up with TTS, keep an eye on compression & as soon as it starts to drop, fit new rings.
de-coking the spanny is a good shout though.(keep caustic soda away from anything you dont want melted - including skin,eyes, aluminium etc)
thats about it.............enjoy.

Dont let it run out of fluids, clean it once a month (with fine tooth comb) and dont crash it.

Waarrrmmm it uuupppppp before going banana sandwich with it!

I'm keeping my NSR for a fair while and by the grace of god it refuses to pull through the power band untill its warmed up a little. By taking the first few miles gentile untill its warmed up you will be saving lots of maintinance (people say leave it to idle but i can leave my NSR to idle for 5-10 minutes and the temp doesnt budge).

If you are interested in good, fully synthetic oil at a good price i would suggest ordering online. My last batch cost me about £40 for 5 litres delivered, its a little hassle with it being in one big 5 litre bottle but its awesome oil and for 7 bucks a litre, not going to complain!

Warm it up as stated.

Shouldn't need de-coking if its running an oil pump.

Rebuild every 10-15k miles as above ^

For me, my old Derbi used to eat plugs. I would probably change them every 1k miles, but I shouldn't have needed to. For the sake of a few quid though I always think a plug change is worthwhile!

Hope that helps

Hey guys, thanks very much for all the helpful advice.. I have had a top end rebuild done this week and had new fork seals..... the only thing i am not to sure about is the oil. the last owner topped it up befoure i left with the bike and i am pretty sure it was crappy tesco stuff.....

I am pretty concerened about people pinching it too haha, thats why its in a locked garage and a massive chain around it too.

Thanks again for your helpful advice

If you're that concerned about the oil, then take it out through the vacuum hose.

Then top it up with some new oil and away you go.

If necessary you may have to bleed the new stuff through the system, but I think you'd only have to do that if the engine decided to seize.
