Getting around 45 mpg, avg...much better that the 37-40 I got when it was stock. What makes you think your's is running lean?...mostly they are over-fueled.
My experience with bikes built to meet the emissions requirements is that they all come lean from the factory.
But the Drifter is the only Fuel Injected bike that I ride, my VTX1800 has a Cobra FI control and it runs great but I don't ride it yet, it is a project bike.
My other bikes have carbs and all of them needed jetting and tuning to run better.
Good question, why do I think it is lean, because it doesn't have any symptoms of lean running.
But it doesn't have any symptoms of being rich either....
Maybe I will try the right side filter mod...
Last time I checked I was at 38 mpg on the highway.
Thanks!

- July 24, 2020, 19:49:37 PMI agree with Troll....had a fuel controller on the bike when I got it...V&H longshots and Big Thunder Air kit....well the fuel controller went bad and started dumping fuel through the injectors and dropped my mileage to about 10 mpg...could keep enough fuel in the tank to get anywhere! Yanked out the controller and everything runs perfect....getting 40 mpg and runs smooth...

- July 23, 2020, 23:27:41 PMHi Troll, I have a question...
I haven't done the air filter mod because it will make the bike even more lean running.
Did you add an aftermarket fuel booster (Cobra, Power Commander, etc) or adjust the FI temp sensor?
The stock intake is very restrictive but more air in requires more fuel too.

- June 24, 2020, 16:19:40 PMOk, so this might get a bit complicated, but here goes. The air filter is small, and is on the left side. The crossover tube between the cylinders has a silencing baffle in it, and it restricts the total amount of air going to the engine. This is on purpose, to operate in concert with the mufflers to decrease total sound. The less air in, the less noise out. IF you take the r/s airbox cover off and ride it a bit, you will notice the exhaust sound is quite a bit louder. More air in, more noise out...I made my own airbox backing plate for my drifter a decade ago, right around the 58,000 mile mark. My fuel mileage went from high 30's to sometimes over 50...plenty of power, and the stock exhaust has more than enough "rumble" for me. The same thing with my W-650..did a "shelfectomy" to the air box and now it's other wise stock exhaust is quite loud. I had to put a jet kit in afterwards, as it was running VERY lean, especially above 4,000 rpm

- June 24, 2020, 12:58:01 PMright side is fake....for looks only. the left is the actual air intake....same on all the 1500 and 1600 engines (I'm pretty sure). If you get an air intake kit you remove both sides and install the system on the right side. You can then get a cover that goes on the left in the area vacated by the air intake...

?
