i was told NOT to do this

here is what you should have to put on a new sprocket. the 2 top rings are original parts, the bottom is a shim i made. whatever you buy determines the thickness of the shim you need. i bought a shim washer, made the middle bigger and slotted the outside for the nuts with a dremel.

when you take off the wheel, you only need to lift the entire sprocket configuration out of the hub. you do not have to loosen the nuts first to
take it off. the whole thing will slide right out. so never mind the new
hub first. park it first and rip it down. if you can get a spacer in there,
that may be all you need. but do it now.! good luck. dont give up.
just do what the other guy who sold it to you didnt do.
congrats on df250rtb ownership. the bike is the balls.

Thanks for all the support! Much appreciated ! I hope this fixes the problem.
Ill do everything I can to get this fixed. Ill be replacing the sprocket with stock one n do exactly what u said to do

original sprocket will let you go about 50mph. that is why everyone is changing them.
'old bike barn dot com' has a sprocket for cheap. the
tooth count is a personal decision. i went with a 38t. yours will have a number
stamped on it if you like how it goes use the same.
then go to your local honda dealer and get the bolts. here are some #s.
i got these from dandaman. very happy with the parts he recommended.

sprocket= JTR27938t. for a 38tooth. the last #s are the tooth count. (36t,or??)
bolts= 90128-382-670

pictures as requested. It's not 100% perfect.. but remember this was done with a rattle can and not my HVLP. I used 2 cans of rustoleum Satin black between the tank and fenders. I could have used less than half of one can.. but I wanted it layed on thick. After the paint was dry.. i used 2000 grit sand paper with spray wax as the lube. Then I used some rubbing compound, followed by a quick finish of spray wax again.

It's more of a matte/satin than a flat which I like. It's a a bit deeper than the stock color and much more resilient. A little spotty in a few places but I cleaned it up nice. Also this paint is an exact match for the stock frame color if you need to do touch ups.




btw idk about yours.. but the bottom of my tank was nasty RUST orange primer. I didnt bother painting this area, as I will re do the paint correctly with my HVLP gun at some point, but it looks fine for now

hey man where did you find that seat ? its nice. im looking for a new one myself

Rode my bike to work today in 40 deg weather 12.5 miles each way. I cant get this thing to shift properly, it locks you out of ALL gears while in first at a stop. So, if I come to a stop at a red light and down shift with the clutch held in as I approach the light, once in first and at a complete stop you cant shift anywhere! Anyone have any luck or instructions for syncing the trans? How would I check if the shift linkage is properly adjusted? I need some help here guys, as I am a b-i-c-y-c-l-e mechanic. Any PDF's or web sites would be helpful OH, and here are some freshies of my mistress!!Attachment 10776Attachment 10777Attachment 10778

hey man my question is where did you find that seat ???

God Goodbar, started the bike up today, 70f here today, put it in full choke cranked. fired and idled like a baby to open. Course I had to take it for a spin just to take advantage of those cylinder break in strokes. Got the new carb filter and I know you think a little thing like that won't make a difference but being the optomist that I am the thing made a great difference. Just looking inside it you know you got a big lean down. More power, less pop and more thump, just great. Was kind of bummed as it didn't clamp down good at first and was interfearing with the throtttle assembly. I took it over to my CNC bench grinder and ground down the connecting flange and put a little negative rake into it ,works great now. Drove by a guy on a Harley, I thought he was going to get a broken neck. So little flash , so much class. As promised:Attachment 10443Attachment 10444Attachment 10445Attachment 10446Attachment 10447 The last pic is my cnc grinder after the flange mod.

JD630, regarding the seat in bobthebobbers picture, that is the standard seat on the 2012 edition of the DF250rtb. You can get one at the scooter depot but it attach's differently so your in for some modifications if you do that seat. Here is a link for the filter.
