Dong Fang DF 250 RTB Bobber Information

[GUN ROD]

Keep it up until I have a hundred miles on it right. Sit back and relax to some good eating. Then I can go a little faster. 50 mph. fluctuating the speed. Then the next day ride it like I stole it! Sound like a plan. Or do I have it all wrong?

This not a cooking forum, but what is a Boston Shoulder? Sounds good. Your procedure should break in your love just fine. Just listen, don't push and you will have a trusted friend on dark roads coming home in the future.

Gun Rod,

I believe the procedure is the same , we just use our recommended specs per the DF manual.

EXCITED! two birds today. Adjusted valves to Alley's Heist instructions, split the difference on gaps. Found factory settings way too tight. Sounds different but smooth. Replaced oil with Royal Purple 10/40 for motorcycles (wet clutch additive) & adjusted clutch cable, guess what? NEUTRAL upon request!

70+ tommorrow, wonder what I will be doing.

It's the shoulder off the biggest fellow you can take down that lives in Boston.

I would try to always stick to our manual as a final spec number since we don't have a workshop manual. The Heist has a Lifan engine, very close to ours, but some specs are different. I did notice on my bike that even to oil level affects finding neutral (weird). I have also heard that different oil brands make finding neutral easier??. How much adjustment did you have the make to the clutch? Just curious since I'm behind most guys here as far as time/miles.

Yea, its starting to look like motorcycle season!

I may try the rear sprocket swap this weekend. I have my tools, sprocket, 520STD master link kit. Anything I need to watch out for? Also what number, if any, did you guys torque the axle nuts to?

Foot control bracket at motor adjusted toward rear slightly. Clutch cable adjusted to max pull. First time too much. Backed off a little, now sweet. Syntetic oil helps too, i'm sure.

Adjusted valves at .006 ex, .004 in ( blended formula ). Start up very easy now, no long warm up needed. Very different sound.

with the valves at 6 & 4 do you have alot of rattle when engine warms up. reason I ask is that at that cold mine sounds good, but at running temp it sounds like it has way to much rattle.

The blend is tighter than our manual specs, but allot better than factory settings ( 0 gap both!)

No rattle noticed, can't explain sound difference, lighter, not as deep.

Secure bike well. Weight of wheel will surprise you. When it's released the bike's balance will change & if not secure it will end up not were you want. Factory sprocket has a rim not found on the JT version. Note studs use the rim to secure. I was able to figure out how to use new sprocket with original fittings. Once assembled putting wheel back on, you would benefit having a second set of hands. Due to lining up brake pads as you put the bolt back in, is an ackward moment.
Torque unknown. Note adjusting bolts should be set evenly (they alline rear wheel as well as set chain length).
Most important tool for the job is the spring washer tool. Sears sells, get the large one.
