I should have titled my post. Please don't mod your scoot if it runs ok and you are daily driving it.
Please DO mod it if you for it cheap/free.. Want to race with it.. Want to do wheelies and go fast. Its a fun little motor.
But it sure lost some of my love.. It gets worse MPG.. Loud..

4 Different forums.
Hundreds of threads and pages about intake, jetting and exhaust..
Called The Ruck shop.. No help.
Called Scrappy Dog. No help. Even Emailed with him and got vague answers that were no help.
Called The Rolling Wrench in Colorado.. No help.
Reading gave me jet sizes from 110 to 130. And then when you look on Scrappy Dog they have "standard" and then about 5 more sizes listed.
So makes a person think "Well I read 20 pages of people using a 115. That must be the correct one because even Scrappy sells that specific size". The info for people is so mixed its silly.
Carbs are all different in the Chinese things. Frames and center stands are different so exhaust fitment is super hard. I searched for a long time and didn't find one for my scoot. But then someone here had a link instantly..
Plus being in this small town, no shops know crap about these motors. One shop let me trade jets so I could try some out and then exchange for others.
It was very hard for me, who I think went into it with a ton of research, to make this all run well again. And its still too loud and i'm still using my stock head pipe.. Should have just put the new tires on and enjoyed it.

Stock jet ended up being a 105. I have a 112 in it now and it is ok. No adjusting the needle on the carb it came with.
Yes I know people truck these things out all the time. But there is also a ton of miss info so even with reading and research its still hard to figure out.
Ive done mods in the past. I knew I would need to change jetting and other parts. But overall the little bit of power wasn't worth the headache. I could totally see someone with even less skills to totally mess up the scoot and would need to hire someone to fix it.
Friend with the 150 Ruck said he likes the power but was a nightmare to get his to run properly also. Still dumps fuel and oil out...

The air filter worked great. That wasn't the issue. The big problem I had was the lack of info like someone mentioned.
But what you don't know is, I read literally hundreds of threads on the different topics. I called The Ruck Shop, and tried to talk to Scrappy Dog on the phone and over Email. And EVERY answer I got was different. They sell jets in the performance section and make it seem like those would be the only sizes anyone would need.
Then frames and stands on the Chinese scoots are so different, I will bet there isn't an aftermarket system that would 100% bolt on. If I didn't have my welder I would still be messing with the dumb system. You have a number to a company that will sell a bolt on exhaust for my 2011 Dong Fang Sunny Scooter?? I highly doubt it. They all claim they fit. And thats half true. But you will have to mod something for it to work.
I have been on 4 different Forums. I have read countless posts about mods, jetting. But the info is SO RANDOM its absurd.
One person did a air filter and exhaust and claimed they ran the best with a 130 jet.. While others I have read need a 112 or 115. When you have no way to measure your stock jet, that makes it even harder. And then you get jets from vendors and they aren't marked either.
I guess what I'm saying is, I got this thing to commute and to have some weekend fun with. The slight performance I gained was not worth it being off the road for a month while I basically had to tinker with it every day. If I bought it as a little project or whatever then I wouldn't be so bent.

So I have a Chinese 150cc scooter. Love the little thing. Have been using it to go to work 2 miles away and also joy riding around our little town. (Lake Havasu) So I rode it so much I ended up needing to replace the cheap tires. Decided to get Perelli scooter tires. And while I was doing that I also decided to order some "performance" parts from ScrappyDog Scooters..
From everything I could read, I thought I would need a 115 jet.. No idea what the stock size was because it wasn't marked. Scrappy offers the "standard" (whatever that is) and then some other sizes. Let me just say you shouldn't just assume one of those sizes will work. Open air filter and tried to "mod" my stock exhaust. That was a HUGE mistake... Ended up having to get an exhaust system off Ebay. Which of course didn't fit at all.. Lucky I have a welder and grinder... So I FINALLY get this exhaust working. Sounds like total crap because its SO loud. Sounds like a chopper. Had to weld the exhaust more because of cheap welds. Got to finally ride it to work the last 3 days and rode it around town today with my buddy and his GY6 Ruckus.
So what I want to tell you is DO NOT MOD your scooter! I was SO pissed at myself. It ran totally perfect before. All I really wanted was quicker acceleration and I could have totally taken care of that with rollers, springs and clutch... Now I have a loud scooter. Sure its faster, but for all I had to go through it was not worth it at all.. Those tires tho.. WOW! So much grip and it rides so much better. Wish I would have just put the new tires on and enjoyed them and not messed with the thing at all.

The internet is full of so much different info about the same thing, its imposable to even get a good answer on something.
Last night I put the stock jet back in. And surprisingly it ran much better. I can tell its running lean because the plug finally changed colors enough that I could notice. And I could feel it lacking in the top end. SO many people said to do 115 right off the bat.. Other posts I have seen say you will need a 130 for sure.. So much crap to read and try to find the correct answer to..
I am going to get a new exhaust. I think mine now, gutted, sounds like total poop. After the new exhaust comes I'm going to start to maybe start with a 110 and see how it runs. Probably should just get a jet kit....

Problem is, aside from just wanting a new exhaust now due to the terrible sound, I don't know what direction to do the tune. Plug isn't clear enough to know what could be the issue. Part of my thinks I might have too much gas.. But the jets from factory were not labeled and the jet I got from scrappydog wasn't labeled but is a "115" jet.. After putting the home made air tube, it seemed to do a bit better with the 115. I put the 128 back in and revved it on the center stand and it started doing the cut out thing again.
Part of me wants to keep trying jets and the other part just wants to order an exhaust and see how that changes things.

Well I "think" the longer intake tube helped it a bit. I put the 115 jet back in and it runs better but still is lacking at full throttle. Charging the battery now since it went dead from cranking the fuel back int he carb over and over. And I put the 128 jet back in to see if that changes anything..
Did I mention how PISSED I am for even doing all this?? Now when I am forced to buy a new muffler, ill have to tune this all over again...

Decided to go to Lowes and get some pieces to make a longer air intake to see if making the carb have a bit more air restriction will help. Hope it fixes it a bit. But the exhaust noise now.... Damm...

Had a friend who is a motorcycle mechanic take a look at it. He said the plug looked good and he also watched the diaphragm open/lift up and said the fuel wasnt cutting out. But it keeps missing at high rpm. He thought maybe its getting too much vacuum from the open foam filter being right on the carb. Sugested I try the 115 jet again with the stock air box.
GD I am so mad I decided to mess with this... So even if the stock air box fixes it, I basically did the muffler and ordered all the parts for nothing. FML..

Well not too happy so far...
Seems the 115 jet isn't big enough? Cuts out at full throttle. I read SO many pages of stuff and thought that would be the perfect size. I haven't messed with the diaphragm needle settings. Is that also something that I may need to do??
And the "gutting" of the muffler.... Stupid idea.. Spent 2 hours cutting that open and then cutting and re welding just to put it on and have it stupid loud sounding.. =( Like a chopper now.
So looks like ill be getting an Ebay muffler after all..
I am kinda pissed that I didn't just put the new tires on and then change just the rollers and clutch springs and see if that would make me happy. But Nooooooo.... I had to drink the flavor aid and do mods.. =)

I was kinda going for the sleeper look. And also not really wanting to spend more cash on the thing. =) Only got it in the first place because I work 2 miles away. Taking my Tahoe to work started to suck. But I didn't expect I would like riding it so much. I had Jettrim in town make me a badass seat cover already. 3 different leathers and pin striping stitched into the top. Ill have to do pics..
Thanks for the replies about the exhaust also. Being its my work ride and fun toy, I didn't want to start having to chase issues if I did something wrong. A buddy of mine has a gy6 converted Ruckus and it seems to have SO many little issues. Mine works more or less perfect so far. For a Chinese scooter.. =)
Tomorrow will be the start up after the motor mods. Ill ride it and then change the rollers out so I can see what difference they make.

Forgort to mention I also bought a new CDI and some 12g rollers to experiment with. Once the intake and exhaust is all finished and I can see what power that made, then ill do the rollers and see what difference that makes also.

Hi Guys. I have a Sunny 150 gy6. It's my daily ride to work in Lake Havasu. Love the little thing. So I bought some new Perelli SL26 tires and some performance parts from Scrappydog. The tires came and my buddy changed them out for me. So tonight I started to do some mods.
Cleaned up all the road grime and then took the stock air box off. I bought a foam filter and a 115 jet from scrappydog. The filter has a steel ring around the base as part of the way it mounts/is built. So I changed the jet first. Super easy. Then put the carb back on and try to fit the filter that "should" fit my brand just fine. But the dumb crossmember is so narrow. The filter will fit BUT, I cannot use the outer foam "pre filter" and the main foam touches the crossmember.
So I wanted to get some options. I have to still spray it with foam oil. It has a little spring inside. Will it hurt to be pressed on the crossmember? It was 10$ so I am thinking of just going with it for now and then later get another and fab a better intake tube.
So with the filter and 115 jet, I also plan to do some exhaust. My plan is to keep the stock pipe and muffler. But I am going to gut it. Cutting the end cap off, then gutting it and putting a bigger exhaust tip on. That way I don't have to buy something that probably wont fit. My scoot has 2 shocks also.. AND I also am thinking the gutted can will still keep a bit of back pressure.
I really just want it to still be reliable because I like to take it to work and out with buddies on the weekend with other scooters in town.
Thoughts scooter lovers?
