Maybe another stupid question, but I looked at this thread about carb adjustment and cannot figure it out. The idle screw is very obvious, but I can't find the fuel adjustment screw. I've looked by the air intake boot, felt around and cannot for the life of me find it. Do I have to take off the left side panel (above the footrest) to gain access? Thanks for the help.

You don't really need to remove the panel to adjust the air screw, although that will work too. I got to mine by unbolting the underseat bucket (open the seat and remove the four bolts holding the bucket to the frame, and then CAREFULLY lift the seat and plastic bucket out of the way. Once the bucket is removed, you have access to the top of the engine). The air screw is on the left side of the carb. You can fit a stubby screwdriver like this one www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=35437 between the carb and the side panel and adjust the air screw that way.

"buckybuck" thanks for the help, I appreciate it. I went out and looked again and finally found it looking through the opening where I had taken off the battery access panel. One more problem solved. Thanks again.

Good to see experienced Xingyue rider helping another out. Just reporting my summer without cage: over the weekend did the 4000 mile oil change. Nothing to report other than the heat shield(chrome piece) on the muffler has crack about 2 inch long at the back. It's buzzing at certain rpm but not enough to bother me. I messed with the fuel sender arm out of tank and indexed per original, now it seems to read accurately, almost to the tee. Ran out of gas on the way to work and had to push the scooter 2 miles to the next gas station. Got my workout of the day right from the morning. Now I know when the fuel gage is 50% or less I have about 25miles to empty(totally empty).

Well I am impressed. After sitting for more than 6 weeks unused in the garage I decided on the spur of the moment to use my wife's Xingyue to work this morning. We have had very cold temperatures lately, coldest -6degC, this morning 10degC and the scoot gave a few coughs after the 3rd 3 second crank. fourth it ran a short while and on the fifth she ran with some nursing. No problems all the way to work. They really are great little scoots.

It's too much coincidence that I ran over a pothole(while leaned over) and bent the rear wheel. Didn't notice it for a few days until another cyclist pointed it out. In my case the 'wheel fall off' point may come sooner than expected! Little sadden by the incident as all was going great at little over 4000miles on the odometer.

I'm back again with an idle question. I have looked at all the posts, I think, and it appears there are two idle adjustments. One is the idle on top of the carb and the other is the brass screw on the left side of the carb (sitting on the seat). I just read a post about intake air adjustment and am not sure if this is the brass screw or not. Is there a third adjustment I'm missing? I've finally gotten it to idle, but after multiple turns both ways with the brass screw it still idles rough. Is it normal for the handlebars to shake at idle? I have no miles on this thing and will be doing the hard break-in shortly, but I've only just gotten it to idle. Does breaking in help the idle? Thanks for the help.

david, the one on top is the idle speed control, the one on the side, brass color, is the idle mixture control. You use the former to set the speed to around 1900rpm when warmed up. You use the later to set correct mixture at idle.
Correct way is to close down on the idle speed control so that you block off the main air path. Then the engine is pulling air through only the idle air path which the brass screw controls. Do this once engine is warmed up.
Once the engine is idling stable at the lowest rpm, this means the brass screw is in the correct position, you can use the idle speed control to bring idle back up to practical level. This is around 1900 rpm. Too high of idle and you engage your clutch pack at rear wheel which may wear out. Too low idle and you will stall when stopped. 1900 - 2000 rpm is good compromise between the two.
Once broken-in, I would change the oil and adjust the valves. This helped with my idle stability. Btw, I did the motoman break-in and never looked back.
One more; I did the 4500mile oil change last night. Went back to using the Rotella 15W-40 from Rotella 5W-40 synthetic. No special reason others than what was available.

To dtwscooter - thanks for the help. I followed what you suggested, which I thought I had already done, but finally I have idle with a cold start. I have tried doing this four times before, I would get it to idle and then the next day it wouldn't do it and I started all over again. I was getting ready to bring it to a mechanic. Thanks again guy, I really appreciate it.

No issues, David. Not sure if you had already swapped out the jets or not. I did upjet from factory originals to 40/115(I think. It's listed in earlier posts on this thread) That also helped alot with the idle issue and cold start. I start and take off in the morning within seconds after the engine fires and it idles rock solid at stops.
I do have in mind to down jet the main however after pulling spark plug recently. I'm thinking perhaps 110 or 112.5 would be better for unmodified intake as is in mine. If I do make the change I will post the results.

Ride report: Yesterday coming back home from work it rained hard. Didn't know at the time but the storm blew gusts upto 40mph winds and in some areas upto 1 inch hail. I rode through on my Xingyue - such a trooper LOL.
Looking back here are some highlights: * traction wasn't a problem, though I didn't test the limits I didn't detect any slippage * wind, side-wind, was biggest issue. I was moving about a yard side to side leaning into the wind and than leaning out after the gust * waterproofness of the scooter was not an issue even in down pour * waterproofness of my riding gear however left a lot to desire, I wore the mesh armor jacket and put on rain poncho underneath - poncho didn't have sleeve protection ! I wore rain overpants and came home dry below the belt * I plan to wax my helmet visor with Pledge so it sheds water easily. Same with windshield and mirrors
I gave my scooter pat on the back once we arrived home. Quite impressed with it . Now the odometer shows little shy of 5000 miles.

Seems like this is the place for scooter foruming. I got mine (a BMS Pathfinder 200 version of this bike) about 4 months ago, and have since put just over 1000 miles on it. I gotta say I love it, even if it is Chinese made. Pros: 16"Wheels give me a great ride Handling is excellent Costs $4 or less in gas (premium-93) a week to get me to work and back everyday
Cons: Average Chinese quality on a lot of plastic parts- the back compartment and the one mirror both have minor issues
I've maxed it out at 65mph with only me on it and at 55mph with a passenger. Recently switched to 10W-30 synthetic, accidentally overfilled the tank (used the side kickstand) and had some problems with it idling. I siphoned off the excess, still had some idle issues, had the local scooter shop take a look at it to make sure it was still good, and to the my overdue inspection- they replaced the spark plug, tightened the exhaust bolts and replaced the backward fuel filter (of course). Thinking about rejetting, but not sure if it will be worth it since normally my idling is fine. Might just need a new battery before long though, hasn't given me problems yet, but it sounds weaker than previously. Anyway, gotta run take a drive. Nice to be here.

I seriously considered the Xingyue. I like the geometry of the bike. In fact, I probably would have bought one if not for the fact that a used 2009 HD 200 came along and I could not pass it up.

I've got some noise coming from my CVT lately (4500 miles). On loaded acceleration (not on center stand), it sounded like a handful of rocks slapping around in there. I took the cover off and cleaned everything up. The rollers were pretty flat in a few places so I changed them out with some new ones. Whatever I did, it sounds better but still isn't right (more like there's only two rocks, now). It's only acting up on loaded acceleration, I can slightly feel the noise through the floorboard, clutch seems to have plenty of pad left and the bell is clean and smooth but I haven't completely disassembled it... any ideas? I did notice the movable pulley cheek on the variator had a very slight amount of play when the belt was removed; can anyone verify this on their's?

Can someone explain what is the "super charge" is there a difference between an ITA-150 (XY150T-7) that does not say supercharge then one that does? I own two differnt ITA-150's and i'd like to know if i'm missing something.

Harry, you can say what you will about those dipsticks but I ordered one off of ebay and saw a 13.47% increase in horsepower (this wasn't on the dyno but I have a very sensitive seat-of-the-pants). Not only that but my top end increased 7 mph and my milage has gone up so much that I actually have to siphon fuel out of the tank every 70 miles. I've also been able to cancel my prescription Viagra and haven't had to order any ExtenZe since the installation.

I own two differnt ITA-150's and i'd like to know if i'm missing something. isawhim once explained this feature rather well last year. It uses the positive crankcase pressure to pressurize the intake system. According to him there were considerable pressure from this system which would increase the intake pressure(less vacuum). I didn't tear into my system to verify but a couple of things stand out: 1. there is more plumbing on our scooter than normal 2. more percentage of Xingyue owners claim 65+mph out of box than other models 3. there seems to be less complaint and less desire to mod this scooter for more power than other models Anecdotal, yes, but my observation.

While it may mean nothing at all, according to all accounts it has a higher top speed than the eCharm (64 MPH) which has the GY6B motor, water cooled and EFI, which is supposed to be better. Of course, it may simply be a matter of the final gearing. Or lack of a rev limiter.

The ITA 150 has a larger transmission than other 150s, mostly due to 16 inch wheels, this scooter uses a 906 belt which is used in a Honda Reflex, also uses a 123mm variator which 250s use, also uses 250 rear torque plates but a 150 clutch fits, but thats all about the bell anyway, a stock 250 carb does wonders for these bikes and ends carb problems, the manifold in an ITA 150 is tops, pipes can be added but need custom fitting or simply buy the best two bros, the engine in these are simply great and accept mods but not traditional 150 ones

Do you know of any performance variators that are a direct swap and what do you mean by rear torque plates? Thanks again, have a bone.

Ok. Let me say this. Sunday I made a 25 mile drive on Highway 16 from Tacoma WA to Port Orchard wa (over the narrows bridge) on my Xingyue ITA-150 and here is what I observed. I was able to get up an observed on the scoots odo 77mph even with wind and buffeting. I did not sustain that speed but kept my speed between 60-75mph the entire way except the mile or so of highway construction were it slows to 40mph.
Now I know the odo is off but this was a comfortable ride and I was WOT part of the way and I didnt fee uncomfortable or that the scoot was being stressed. Next time I'll do it with a GPS. BTW I also had a friend trailing me and he said I was never below 60mph except in the noted construction area. I am impressed so far.

I had stuttering issue at mid-range, 40-50mph per other post. Changed the main jet from 115 to 110 and that cleared up the issue. It's running stronger than before and fuel economy went up to boot, about 15% increase. And no stuttering!
I recommend rejetting from original 35/103 to 40/110.
This is using regular grade gasoline(87 pump). It's a good combination.

I don't know why I didn't do this earlier. Today out of whim, I changed the rear shock pre-load setting from full soft to full hard. It made the ride improve significanly. I'm 5'11'' and weigh 190lb. This change makes sense as the shock absorber damping now matched the increased spring rate.
The change can be made by hand or use large channel lock pliers if more leverage is needed. Give it a try.

Just a general observation, but it doesn't look like Xingyue is making the 150 anymore. I've looked around the web and the only one's I've seen are 2007 or 2008. No 2009's anywhere. Scootertronics carried them last year and really liked them a lot. Now, they don't sell them. I hope this is not the case, but if it is everyone better take really good care of the ones they have.

I don't have picture of it but at the bottom of the rear shocks there is section that you can twist to get different pre-load. The soft setting is then the scalloped cam follower is in the highest groove, hardest setting is the opposite. Once you look at it you will see it.
