New one to me. I could see moisture on the out side of the tank but not fuel.
Never heard of this problem with motorcycle tanks but only been fooling with bikes for 50 years.

I don't have this problem with my DF tank. Where does this bead of gas appear?

I did have a very slight leak where one of the mounts are welded underneath the tank which I repaired. The crack was so small that I just smelled fuel and had to pressurize the tank to see the leak.

Here is a picture of the seat issue some of us are having. Attachment 4735

The cap is vented? The venting should be to a charcoal canister. The cap should seal air tight.

I have a suggestion....

Hey All !! My name is Leo ... I've read all 90 pages, so I feel like I know you all already. I can't thank you all enough for all the great info.

I have to say ... I love my DF250RTB. I got the gloss black (just enough chrome.)

Here is a picture of my 6'3" son on it ... he wants one now !!

I ordered mine on a Tuesday from Sunny Sports ... got the tracking # the next day ... got the bike the following Thursday. I did the assembly, battery, oil change, etc. and put it in the garage. The front right turn signal was bad (tried swapping bulbs with no luck.) I was gonna call on Monday afternoon for the MCO and the turn signal, but the MCO was in my mailbox on Monday morning. I called about the turn signal, so they shipped a new one on Tuesday. Called Progressive to add this bike to my policy ($75 for liability and roadside assistance.) Went down to DMV on Tuesday and registered it without a problem.

I've ridden it a couple times and it is a blast ... except for first gear (I've just been starting from second gear.) I ordered the 35-tooth sprocket from the place barnone recommended, and some drag bars off ebay. I also plan on doing the other mods that you guys have suggested.

No charcoal canister on the DF, not CARB compliant.

Leo,
Welcome to the DF forum. All input is appreciated.

I am glad that you had a good experience with Sunny.

I could not open your photo.

Babyswiss,
Wow. Someone at DF really dropped the ball on this one. Quality control? TIC big time.
So it's the seat that is off to the left but the seat bracket/post is ok?
How about a photo showing a side view?
Thanks
