It looks like some kind of recirculateing system for emissions. If this doesn't hurt anything I think I am going to get an aluminum hose and run it down.

it is the secondary air injection, make a plate with a gasket and block it off.
Air injection for what? It went into some kind splitter one hose went no where the other back in the intake.
Hey guys, I've been reading all over this thread and have obtained a lot of really useful information. I live in Texas, and I'm currently saving up to purchase this bike from Scooter Depot.
Barnone, I have a question for you. How exactly did you rejet the carb? Did you just switch out the 88 for the 100, or did you switch out any other jets? :P
Oh, and what top speeds are y'all getting with your bikes? Can it go at highway speeds?
Mine has a top GPS speed of 65 with a 100 jet, 35t sprocket and that hose I still don't know the name of off.
Was that the only jet you switched out? Is it difficult to switch them out? ...and one more question (lol)... do carb jets need to be regularly replaced, or is it essentially an "upgrade"?
Mine came with a 105 jet, which I an going to switch back. It is just an upgrade thing. You should not have to do it again.
Yes that's the only one I did and it Is very easy.
I just need to be sure that I can travel at highway speeds, so anything that can up my top speed would be great.
top speed at close to 70. secondary air injection is for emissions. i have read here that eliminating it gains around 1 hp & makes the motor run slightly cooler.
Put a 35t sprocket on today. Much better. I've also got a 520hd repair kit I can't use due to barnones
Post. Oh well, I'll use it one day maybe. Jets coming this week. Bike still runs good. Still waiting on MCO from Chad . Really annoying waiting on the paperwork.
Barnone, where did you get the block off plate for the secondary air injection? thanks
I made the block off plate out of 1/8" aluminum plate using the gasket as a pattern.
The Secondary Air Injection (SAI) pumps air down stream of the exhaust valve to help burn off gas to reduce emissions. Removing it should reduce engine temperature some but should not improve performance.
call,
I replaced the main jet with a 100. My DF came with a 88 size but others are reporting different sizes so I would look at what is in the carb before ordering jets.
I put a washer under the needle to richen up the mid range.
When i had it open i was getting better performance. I don't know what will happen blocked off.
What do you call highway speeds?Quote:

IMHO, on the interstate you need at least a 500cc bike. Plus remember these are hard tail bikes so the handling is compromised.
BTW, I am getting PMs from Heist owners that are having problem getting their bikes to run properly with the carb mods that some are doing including the Weaver carb. My advice is to run the stock bike for a while and then do the mods one at a time to see what happens. Don't shotgun a bunch of changes.

Barnone,
Nice one! I was joking, my fault for not checking it first myself. Maybe I'll upgrade to a 520hd later. I didn't need the kit anyway, took a couple links out and used the orig master. So dont worry, I'll be fine. Took off the sai also. The motor runs smoother, especially on deceleration . I'm not gonna mess with the carb for a while cause she's running good right now. Take care Vince.
Anybody know of a larger aftermarket gas tank that fits on this bike?
I don't know of any larger tank that will fit on the DF without mods but should not be too hard to fit one. The stock tank holds a little over two gallons which gives me a range of 150 miles or so.Quote:

Got my DF250 a week+ ago. Damaged in shipping, lights/blinker not working, broken turn sigs, oil leak (slings from chain onto frame and rear tire) and other problems. Already spent $100 to get the lights looked at, and my mech can't do anything about the leaky seal without a replacement seal.
They just drop ship from Sunny Sports and I can't get ahold of them...715-345-0453 no longer a working number. Tried many, many different ways...even got the owners number from Sunny Sports but just leave unanswered voice mails.
Anyone else having problems with finding neutral? Or is this yet another issue with my bike?
Seems like I'll pull up the shifter, wiz right past neutral into 2nd, then push back down and skip N for 1st. Got to hit it just right...and by that time the lights have changed.
BTW
Barnone:
How are you adjusting the seat suspension? and re the saddle bags you got off bay are those the soft or hard sided ones?

I had a problem with neutral also. I changed the oil brand and it has improved. It will go in neutral easy 9 out of 10 times after the oil change. Sorry to hear you had problems with your bike, I had a few myself. Luckily I was able to fix mine without having to call, and there are a few issues i should call about like a leaky tank and ripples in the rear fender. I just don't feel like waiting on hold for 20 min and having one of those rude ladies answer and tell me it's my fault.
It will require some modification and fabrication to work. I'm fitting a Gilera tank right now and the two issues I needed to address are the horizontal tabs for mounting the stock tank (I bent them up against the backbone) and the voltage regulator (which I have to relocate and shave-down the mounting bracket. Both were interferring with the tank's tunnel, not allowing the tank to drop down far enough. That's all sorted now. I only need to media blast the tank and do a little body work before painting.Quote:

No problem finding neutral for me.
The first time I adjusted the seat height I took the bolts out of both ends and took the spring to my vise to break it loose. After that I could just take one end loose and turn it to tighten the spring to raise the back of the seat for my weight. I now have the preload to the max for my 210lbs. Lighter riders might not need as much preload.
The saddle bags are stiff synthetic material made to look like leather. I got them off ebay but can't find them anymore. Sorry.
AKA what oil brand and weight did you end up using that solved the elusive neutral issue?Quote:

I used castrol 4t motorcycle oil and have no problems with neutral.
The ccw/pit motors site has the heist style gas tanks that will fit this bike if you like those.
Gump out.
A Gilera tank! WOW. Need to see some photos of your DF with the tank.Quote:

i know i just threw a lot of questions at ya'll but thanks for any replies
Well I've got 40+ pounds on you barnone so I guess I'll have to pre-load it.
Shame about the saddle bags as I like how yours fit. Have to start searching around or have some made. Know if they were made for a specific bike/style?
I'll have to get a seat cover too. Left her out in the sun for less than an hour and just about burned my ass (wearing jeans) it was so freaking hot...like sticking your ass up to a fire for too long.
Finally heard back from extremescooters.biz today so we'll see if I get the needed parts.
Anyone in Austin,TX should take their china bike to bad boyz cycle. Great guy (Mike - Owner) that doesn't mind working on them. Did remark that he thought the frame was well put together and that it was fun to ride. And he a Harley guy.
Still in the engine breaking period so I'll switch oil after that and see if neutral is easier to find...might have to put some hair around it.
