250-500cc Just bought a 2014 WR300. What carb/jetting?

I've thought about the cable. I'm sure the draggy clutch adds to the idle. But like I said, It's only been a problem once since 2011. I've also found that certain gearbox oils all but eliminate the clutch drag. Out in the dessert, never a problem.

On Saturday, I ordered a JD Kit for my '08 WR250. I rode a WR300 on Friday with one and it was a huge improvement. I have the Terminator clutch cable and its money well spent.

If anyone needs a cable. I have one and other things I am going to post in classifieds since I am Huskyless.

I like mikuni more than lectron. Lectron has cheap aluminiun slide what wears out quite soon and fine tuning is very difficult.

Lectron. 110% Lectron.

I had less than 100km on my WR300 when I bought her, and the hard starting and off jetting immediately drove my insane. After spending a couple of weeks researching on here I bit the bullet and ordered a Lectron. Less than an hour to install on a bike I'd never taken apart before, less than 30 minutes to get set up, "jetted" and ready to ride and give me a plug reading I was very satisfied with, and gave me a great boost in power over stock jetting and rideability. Simply cannot rate highly enough.

I don't get how you guys are reporting a 50% decrease in fuel consumption. Isn't that also a 50% decrease in engine lubrication? Why would the Lectron allow the engine to run that much leaner, and still be ok?

Its called atomization..

Does atomization somehow increase the amount of oil going into the engine?

Well, on the first page you said:

32 from 22 is 45% more...

That picture of your plug looks great for sure. I just don't get how it's possible! If you're using 50% less fuel, you're getting 50% less oil, period! Does that mean we could all go from 40:1 premix to 60:1 premix on normal carbs? Maybe, I guess that wouldn't be too crazy, plenty of people run 50:1...

Of the fuel you're using the same oil ratio applies. Even a gas powered string line trimmer is now reccommending 40:1 where other brands still say 50:1 on these small air cooled motors that run high rpm. I've rebuilt bikes using 50:1 with good jetting and found zero oil buildup beneath crank. IMO that's a bad thing for longevity. I use 32:1 with jd jet kit and have similar looking plugs and no spooge if on correct needle clip.

32/22 = 1.45455 = 45% more?

Probably not worth arguing about this...

Kyle, you should ride my bike again now that I sorted out the power issue (flywheel weight related). I still have recluse, so it does takes really sharp edge off, but than bike is sooo smooth.. and I am still messing with powerjet to see if I can get more.

Sorry. 50% better gas mileage, you're right, that's 70% as much oil. Not as bad as I thought, but still nontrivial... My bad!

Obviously these things are working for you guys, I have zero doubt about that. I just wonder, with the fuel mileage gains, are there engine longevity tradeoffs that are coming with them? Hopefully not!

whoa im confused^. 32mpg is 45% better mileage than 22mpg(33mpg would be 50% better)! i can see your point Kyle but most economy woes i guess are to do with jetting & set up(overlapping circuits as stated, unburnt fuel, leaking breathers, float too high, too rich in general). either way im happy with my lectron & bottom end had plenty of oil in there when did 165 top end a month ago! at 32:1 with good oil i reckon it be sweet but yeah i guess its getting less oil per mile?!

I cant tell you exactly what mpg I get now with lectron. But let me put it this way...I am now pissed at myself for selling my stock tank. The ims I have now is overkill. There's always gobs of gas left over now as compared to before. I usually do 40-60 mile trail rides.
