I can handle the bumps with my back. But for some odd reason sitting on uncomfortable seats hurts my back.
They get over 75 from the 130lb Chinese test rider and the downhill ride for them. Lol. Honestly I have no clue, but either of those do seem plausible.
the speedo said 73 but the gps said 63.
AKAsam, did you put on a 35t? Anything on the front? I was just getting ready to order a sprocket for mine if it ever ships, but didn't know if I should go with a 35 or 38. Do you lose a lot of bottom end?
no change up front, just the 35 in the back. I didn't loose anything on the bottom end. It actually rides better now, smother, less vibrations. This bike should have come with that sprocket. Before 5th felt like the main gear, but now 4th is and then you are surprised you still have another. Best buy for this bike so far. The Link Barnone posted was were i got it and it fit just right.
I do have a problem now with the spacing of the tire thought. I will have to add spacers so that my chain does not hit the frame and the brake bracket does it the rear rotor.
You need to change the main jet to at least a 100 and add a least one washer under the needle to improve the top speed. The stock jetting is very EPA lean.Quote:

Barnone: Did you have any spacing or chain hitting the frame issues when you changed the rear sprocket?

You can't change the front sprocket without doing some grinding to get clearance for a bigger front sprocket. The chain is a 520 and I guess you could go to a smaller 428 chain like the Heist has and then a larger front would fit but why go to the trouble.
AKAsam,
You must have put the wheel spacers or the sprocket on wrong. Did you leave off a spacer or get them mixed up? The sprocket has to go on the same way as the one you removed.
Post a photo of your rear wheel as it is now installed and I will compare it to mine.
I got the sprocket changed at my local motorcycle shop. I don't have a chain tool and it only cost $20 to get it done there. After taking everything apart i realized that he did not put the sprocket back in the rim all the way and he also got the two washers mixed up. It is all good now. While i was dirty i went ahead and took the carb apart and to my surprise i already had a 105 main jet in there. I bought a 100 so it didn't make any sense to change it. I did put a small spacer on the throttle needle though. Will see how it runs tomorrow.

I have a chain breaker from Harbor Freight which I have used for years. On sale for $10. Good for my needs.

Don't understand how your DF could have a 105 main jet. Did you buy your bike used? My DF came with a 88 and I put in a 100. I think the 105 is too big and the engine is not going to rev out properly being overly rich.
You might try the 100 if you still can only get GPS 63 MPH. I'm not sure what my GPS top speed is but I would guess maybe 70 MPH.
I got it new, right out of the create. I changed the jet just to see of it would make a little difference. I took it back out and the sprocket started rubbing again. I took it back in a realized that the sprocket was backwards also but then i notice that it looks like there is supposed to be some kind of clip that hold the sprocket to the rim and i do not seem to have it. Barnone can you check and see if your has a clip?
There is a very big c-clip that holds the sprocket on which the mechanic that changed your sprocket must have left off. You should be able to see the groove that the c-clip fits in when the wheel is off. That clip is a bitch to remove and replace without large c-clip pliers. Harbor Freight has an inexpensive set that will make the job easier.
Very dangerous to ride the bike with out the c-clip because the chain or sprocket could jam causing a rear wheel lockup.
Maybe you can go to his shop and find it?
Weird about you DF coming with a 105 main jet. TIC (this is China) at it's best.
when I changed out my sprocket there was only one large washer & one large c-clip
My DF came with a 88 main jet while AKAsam's had a 105.
Can any other DFers report on their stock main jet size?
Might be wise to check your stock size before ordering new jets.
Just a reminder that when you put the float bowl back on make sure the accelerator pump is set so that it still works.
if I remember my main jet was a 100
Barnone:
I saw you mentioned a chain breaker. Can't you get the rear tire and sprocket off the bike without seperating the chain?
When you drop a sprocket 10t like I did the chain will be way to long
What is the final decision on the rear sprocket? 33,35, or 38 tooth? I weigh about 240 lbs.
AKAsam answered the question. The chain breaker is for shorting the chain.Quote:

I tried a 33 but it was too tall and then I went for a 38 for here in the mountains but I think the 35 is probably a good choice.Quote:

How many links did you have to remove with the new sprocket? Since it has a master link can you just use a chain breaker to remove a few links and then reconnect it with the master link? Also, was it tough to realign the rear wheel after the sprocket replacement?
Yes you can reuse the master link but some recommend that you always use a new master link.Quote:

Also nice to have the kit in your tool bag.
Realigning is easy since both sides of the hard tail have good alignment marks. Also it is easy to sight down the chain to check you work.
Barnone: Thanks for all the links to the parts websites. I thought you mentioned earlier that it was a 520 HD chain not a standard chain?
Good catch. I need to go back and correct that post. It's a standard 520 chain. What post number please.Quote:

Thanks. I corrected the post.Quote:
