First 2-smoke, first Gasser, first ride, first PICS !!!

[Jakobi]

I'm with Trev. The 09/10 headlight and fender tickles my fancy most. When I get to fitting the 2011 plastics I think I'll be leaving these parts off.

[sevenfourate]

Are the later ones THAT bad.....Or are the earlier ones just a little more eye-pleasing ?

If i post a picture up, can someone else with a later model do the same ? Its all new to me......

Just google different years and you'll get the idea. 07 was a bit chunky and agricultural looking. Then they were like yours through till 2010, then went to the more ktm style light.

I can Google as easily as the next man........

(It was to get a discussion going really !).

Never mind.............

He's now offshore for 3 weeks, but i believe its just about finished !

I'd love to meet up at Thetford sometime. My friend with the trailer has a Gasser 300 EC too - so that would make 3 of us. Almost a "Club-meet" in these remote parts ! I'll PM you my mobile number in a moment.

And interesting about more oil - and jetting to suit. Thanks to Houndog too for the write-up and explanation.

Anyone of you UK'ers know any 2-stroke 'specialists' for carb setting up in the East ????

If you need any help at all with jetting etc give me a call. Been working on vehicles since I was teenie, working on bikes since I was 17, I don't think a day goes by where I don't tinker with it a little bit. I've got tonnes of jets too.

http://www.ebay.co.uk/itm/stage6-Kei...-/400591612142 - set of pilot jets

http://www.psntuning.co.uk/scooter_p...hp?prt_id=1637 - set of main jets (check, you might want a set lower than this!!)

If you have a look of spooge, it is ALWAYS down to rich jetting, low compression or right hand crank seal. As mentioned, I am running 32:1 with no spooge whatsoever, personally I would just try putting in 32:1 for a start, this will lean your jetting out slightly, it may ride better or worse (if it is still rich then you will have a surplus of oil, the bike will load up).

How well does the bike idle?

Im mechanically minded - im an Engineer by trade. However; im not an automotive Engineer and im definately not a carb expert.......Especially on 2-strokes.

I had a play with jetting on my XR400 (successfully i might add) !, just about got there on my WR250F, and also sorted a TPS problem on my KTM 500. But 2 strokes is all new to me right now.......

Im trying to get my head round 32:1 being a leaner mixture than 50:1 ! So your saying the mixture with more oil in it, is leaner as it has a lower percentage of fuel in it and therefore burns hotter ?


Bike wasnt very that easy to set-up to idle - I did read-up something about the pilot jet is too small (?) as standard, and the air mixture screw is almost all the way in, but actually idling wise now its pretty clean and strong. Never stalls and doesnt hang and the choke works fine...

[djroggen]

More oil means thicker fuel, and that equals leaner jetting. Less fuel can make its way through the jets.

Thankyou. Does that mean an offset of running say 36:1 compared to 50:1 would be better MPG ?


All the info i can find says fuel tank capacity on a 2006 EC 250 is 9.5 litres.

As my tank is completely full right now (I mix up 10 litres at a time with 200ml of oil) this means theres approx 190ml of oil in there @ 50:1 ratio. Few quick calculations show:

50:1 = 190ml of oil for 9.5 litrres
36:1 = 263ml of oil for 9.5 litres
32:1 = 296ml of oil for 9.5 litres

Wonder if i should remove 73ml of fuel and then add 73ml of oil to get that tank to pretty much 36:1 ration to see how that runs, and see if i get less spooge, and if its a little 'crisper'..........

[motopsycho87]

I just do mine at the pump, if I put in 2549ml then 2549/32 = 79.65 or 80ml.

Personally I doubt changing the premix ratio that little will do much, you are talking about a 1% ish change, you can't buy jets that are 1% different to eachother (there is always an argument that changing premix changes your jetting, but if you do the math, it's crap).

Answer these questions and I should be able to help you out. (the more information the better)

How well does the bike idle?

How does the bike ride up to mid throttle?

If you hold the throttle still at mid throttle, does the bike lurch and sputter a little from the exhaust?

At full throttle, does the bike rev to the moon or appear to lose power before it feels like it should?

When warm, does the bike smoke at idle, full throttle and anywhere in between?

When you decelerate do the revs 'hang'? (take a long time to drop)

After a nice long run, does the bike's idle drop significantly compared to cold?



And if you do know them

What pilot jet?
What air screw setting? (turns out from stop)
What needle and what clip? (clip from top, top=1 bottom = 5)
What main jet?


You've said the idle screw is almost all the way in, that denotes lean idle, thus adding more oil will make it worse. You can pull the choke slightly when the bike is warm to see if it helps the idle, this will 100% confirm lean idle.

That being said, if you are getting excess spooge, then perhaps the needle has been raised to compensate for a weak bottom end?


And yes, your statement "Im trying to get my head round 32:1 being a leaner mixture than 50:1 ! So your saying the mixture with more oil in it, is leaner as it has a lower percentage of fuel in it and therefore burns hotter ?" is 100% correct, the difference to viscosity is negligible.

I love your rear light, don't suppose you know where it is from?
