Poor gas mileage 2013 christini 300 with gasgas ec300

[lneil06]

Rode 53 miles yesterday - rolling into the gas station with a dead bike - ran out of gas - it took 2 gallons. realistically 26 miles per gallon.

The bike power was good - burned relatively clean - only a little oil on the muffler. Had to adjust the rekluse - was slipping a little bit.

Blue Needle - slot 2
40 Pilot Jet
172 Main
Float height 9mm

that is 11km/l which sounds about right for a 2t - sounds like the christini tank is smaller than the standard GG tank - i think my tank is about 9l wich is about 2.3 litres

my 2014 christini tank is only 2.2 us gallon or 8.6 litre or so the old clear tank were a tlittle bigger at 2.5 gallon witch is close to 9.5 litre...if anyone want to sell the old tank i will take it as it is better than carrying fuel in my back pack ...

Looks like a 100% improvement in fuel economy, not bad for a needle and jet change. I'm not saying it's perfect, but that's much better than it was, right? I think I get 60 miles with my 2011 stock tank, maybe a touch more, but I have a Lectron, which is supposed to be a bit more economical than the Keihin.

i wish i was doing 26 mpg i am going to do same set up as you for my jd jetting (i cannot remember what altitude you riding but i have everything to gain for trying ) also maybe you mean you were on reserve as steve said that the old tank like yours were holding 2.5 gallon ...
and good news on you mpg improvement ..also what type of oil are you using on you recluse as mine slip too

Oil wise - I'm using the Rotella 15W40 Triple T Engine Oil. I was using full synthetic and it was slipping a lot. It was still slipping a little bit Sunday - I backed off the Rekluse - and it was much better. I take it out of AWD on the road - and put it back in when the trails get bad - which should help a little with gas mileage.

I emailed GasGas and they mentioned 60 miles was a stretch for them - the Lectron SmartCarb would help a bit - but not a TON.

Pick up the external tank. I wouldn't buy the white tank I have - especially if it's only .2 more fuel - not worth the extra cost.

Now you have me thinking about my stock tank - I need to check the size of it as well.

well install jd jetting
2-3 th gear 1/4 throttle noting heavy
450 ft elevation
blue needlle-- second clip
175 jet (i dont have 172 on my kit as i have (165--170--175--180)
40 jet
i did 60 klm (37 mile) before reserve ,,then 72.5 empty (45 mile)
tank hold aprox 8.2to 8.7 littre (2.2 us gallon)
Its like 23 mpg i am getting now,, not the greatest but better than when i started that journey (14-15mpg)

going to pull plug and post picture as i am no expert and you guy can tell me if i should go 180 or 170 to get better millage as it seem to be again way too rich
thanks

At 1/4 throttle the main is not in use, the main jet usually kicks in at 1/2 (half throttle). So if you want to go leaner at 1/4 you have to play with the idle jet and needle (the needle barely is in play at 1/4 if at all).

However even if you go a tad leaner on the idle jet (let's say a 38, witch i am using in the summer with the JD kit even tough they recommend the 40) i don't think there will be a noticeable increase in mpg.

I'm no expert in jetting, so take with a grain of salt and wait for the experts to advise.

I have the clear tank on the Christini and it doesn't hold when I ran out of gas it only took 2 gallons - and there was just s little in the right side pocket.

I will be trying a lectron carb once I get my forks back - I'll keep you posted.
