I use Lucas semi synthetic high performance oil in mine and have no issues shifting. I am due to change it now but have been too busy with other things. It works well so Im sticking with it.

maxima premium 4 motorcycle specific 10w40

cheapest unleaded , 10/40 w car oil , loosen the clutch up a bit helps with nuetral it comes a bit tight , but nuet still finicky

Rotella T 15w40 heavy duty diesel oil in my bikes that don't require synthetic.It has zinc add to help with the clutch.Car oils have friction modifiers that will cause clutch slippage.Ask me how I know.:rolleyes1: In my bikes that require synthetic,I run 20w50 Valvoline 4T.This stuff makes transmission silky smooth,but at 11.99 it's pricey.It does help with fuel mileage on my bigger bikes.

Wish i new this this 2 hours ago, for I looked high and low for the 15-40 SE the manual called for. Went with Castrol 10W-40 4T for motorcycles, being Castrol treated my real car nice for the last 17 years. Also it was the only SG, rather than SJ/SK/SL that everything else was; but this leaves me really concerned.

First ride, twice I couldn't even find gears on the way up. Top that with the stock sprocket and the cars behind me were pissed.
To make it worse, I believe the manual asks for no more than 25% throttle for the first 150k.

Well all this is fine with me as i get used to the bike. Now I dont have any experiance here, but I think these springers are very tricky. I only have my NSR to compare with but with the lack of damping I really have to be on the look out. I can imagine going for the brake and/or clutch, hitting a bump, and the bike jumps out of my hands...

Anyway, ask me again in 500 miles when this is old news...

It sure looks cool though...

Hey, is this the stuff??

thats not diesel but rather "Engine Oil"
< $42 for 3 gallons if you subscribe, (you can cancle the subscription anytime)

Under 4$ an oil change seems a pretty darn good deal

this bike is kinda pogo sticky on the road and the springer could enhance that, or not, i dodge anything not smooth looking. here in las vegas 95% of the tar is very nice. the rest is only real nice. the bumps are mostly melted tar at red lights from where cars sit and wait
to go or speed bumps and/valley gutters(cement drain ditch in your path) or cruddy finish jobs around a manhole. i avoid it all. all motorcycles seem to jump off the road to give a good thrill at some point. the only one i had that did not do that was the road star, and the morphous. they suck up the road real nice. but this df is an all'natrual born jumper,being all rigid 'n all.

38t eh? how much do you weight?
Im almost 160lb, and I almost feel like i could just throw out 1st gear, if not 2nd also...
I also find myself constantly find myself looking for 6th and cant believe its not there...
a sprocket change is all but necessary, after i get comfortable on this thing.

Speaking of which, I find myself clenching the grips way hard subconsciously fearing the front end to buck. You really feel everything with these springers.
Honestly I don't think i like it so far...
I dont recall feeling on edge when riding my NSR it was always a pleasure.
But i dont know if it is maturity or great wisdom but i cant let myself feel quite that relaxed anymore, and I believe its the springers are a major reason for this....

Im a noob biker so I used to do the deathgrip thing on my DF as well. Messed with my hand as I lost feeling and my hands would fall asleep. I loosened up a bit and problem solved.

Your not new to bikes so I feel better about my own mistake. But just FYI, foam grip covers are almost a must on this bike. Best upgrade so far and I wish I had them a year ago.

axa only said search for a dealer , if there isnt 1 there isnt 1 , but dong has quite a few " physical address's" around the US (all scooter depot) and a 1/2 dozen websearches willl tell u if 1 is "local"(in state) able to do all the paperwork for ya

I dont know where lower hudson valley is , or id search u state n post the drop shippers I find , matter oh fact that be nice if all would tell wer they got there bike n how hard it was to make highway legal
