So I have a completely stock SSR x6. It has a 150cc gy6 with fat 10" dual purpose tires. 130  10 front 120 10 rear. It seems to pull well all thru the revs, pulls up hills well, can hit 45 on hills, but on a flat it just won't go past about 52mph indicated. I feel like I can squeeze more out but idk how. Is it just my knobbies slowing me down? Or could I need different weights? Idk what weights it has stock haven't opened it up yet. Im thinking maybe I'm lean at wot maybe, when I checked the plug it was mostly white with just a tiny spot of tan. It just seems to fall flat at 50. Seems like most ppl get a tiny bit more than I do. Do u think its an a/f issue possibly? It has plenty of power just lacking a bit on the top end. Any input is much appreciated. |

Have you done any modifications yet? A/F could definitely be an issue, as well as light rollers/sliders, low tire pressure can affect as well, a worn out belt is not helpful.

No mods yet. It only has 400 or so miles so I doubt the belt is an issue. I bought a box of jets but i haven't changed em yet, gona have to deal with my tamper proof carb which I'm not looking forward to. As it is I can't even adjust the AF mixture iys so annoying. Haven't played with the variator yet.

These things come leaned out stock. They do that for emissions, and gas mileage. I would up the jet. Do you have a tach on it? What RPM does it run at? As in, what RPM are you at between 20-40 mph? That will give us an idea as to whether to get heavier, or lighter weights.
Up the jet 5 at a time.

No tach unfortunately. I'm just gona play with the jets. I'm Gona have to drill out the AF screw..and most likely make some slots in the screws for the float bowl. I'm praying once I take out the carb that the bowl screws aren't tamper proof, I know my AF screw is plugged so I'm guessing the rest is tamper proof. Such a pita

Well I hope so. I've heard of people getting ones with the float bowl riveted on! I'll see tmrw when I take it off. I would like a tach though, how would I wire those up?

I would just order a new carb. They are only like $25. Screw all that. Just get a new one you can adjust.

Ya, I was gona order one. But if its only the AF plug I can drill it out in like a minute. I already have a box of jets so I'll be good to go, no point in wasting 25 bucks if all it takes is a drill. I'll freak out if they sealed the float bowl though haha. I'll see tomorrow.

Success! took apart my carb and it only had a 105 main so I put in a 108. Then I drilled out the plug for the af screw and played with it. It seems happier, definitely way more responsive. Didnt have enough road to really test out my top speed, but regardless it seems happier and im less paranoid of it running too lean and hot. Gonna test the top speed when I get the chance and ill see if it made a difference. If not would it be a good idea to try the 110? My airbox is stock, everything stock rly... what tends to be a good main jeg size for a stock setup. I have the 108 which im using, a 110, 114, 115 and more.
