Anyone know the the bolt size for the bottom bolt closest to oil drain plug for a 150cc roketa. From my searches they seem to be the same for most scoots. But can't for the life of me find anyone who sells just the hardware.
Mine musta loosened up & fell out so I have nothing to go by. I'm @ lowes now hoping to pick 1 from what I remember. It was the only bolt that wasn't all the way threaded.
Thanks in advance, speed

26mm carb jets

It's all I've ever used so I don't get how it's to big. Own 2 bikes & 1st came with a 26. This had a 24 but with all basic mods, exhaust, sliders etc. 24 wasn't enought. So been running the 26 for 2yrs now & no issues. Until I put the performance shorty exhaust then I noticed the header pipe was getting burnt & exhaust pipe was super hot.
From my experience this is a symptom of running to lean. So I bought the 115 & 120 jets & only change that occurred was now it's loss of power @ around 30-40.mph.
Not exactly sure since my gauge is off.
Also put in a 24 & bog gas well.
What else would cause this?

Well I'm @ a stand still here I've checked over everything here & I'm literally stumped! Bike started normal, takes off great & acceleration is good but as soon as I hit either 35-40 or a bit faster roms just shoot straight down like it's about to just die stall but when letting off throttle & bring it back it spits & backfires.
150cc 115 & 45 jets needle clip is in the middle
Uni filter. No holes in lines or manifold boot.
When I pulled plug it was black.

Ok so I am all kinda of confused!! I ordered a #115 & #120 main jet & #40 pilot. Started with 115 & the bike just bogged & popped with slightest turn of the throttle not to mention barely ran. So went to 120 & no dif. So I've got about 5 jets with no #'s on them so I just started down the line until it started up fine, idle was good then took it for a ride & couldn't get past 25-30 or it'd bog down & pop on decel. So I moved the needle clip down 1 & can go a little bit faster but same. Any ideas ?

Thanks for bringing that to attention that some "cheapo" oil coolers could actually do more harm than good. I know this first hand. Had 1 burn up my top end so never again will I buy a cheap version

Ok so I can not find a starting point for jetting my 26mm carb. All the jets I have, have no numbers on them. I've ordered a few & no # on them. So maybe ya'll can help.
150cc with aftermart exhaust
Slider weights
& uni-filter
I don't know whats in it & I know it's the wrong size bc my exhaust pipe is way to hot.
Haven't pulled plug yet to see how that reads but will post after
Thanks ahead

Ya def not an a/f prob or carb. Can't be the belt either because I ran different clutch with red springs and the bike ran fine.
It idles about 13. But it's not an Idle really. So I turned the idle dwn even more & the wheel stopped spinning but it's idling so low it'll stall if I don't keep giving it some gas.
It's only with yellow springs.

Tried that & no matter how I config it it's the same.
Either throttle adjust is to low & stalls or to high & clutch is always engaged. There's no in between, pretty annoying actually but I do find there is considerable more power @ the jump since it's ready to go. But don't want to be buying clutches every other wk.
So with this said do u think it could be jet related?

Ok so I can't post pics from my phone but last time I was on here my clutch arm broke & now another 1 broke a few days ago. The symptoms that it was the clutch was exactly like before. Everything was perfect except on deceleration and trying to stop. Bike wouldn't stop so I'd have to kill it @ every light or when I needed to stop. "Very dangerous" so awaiting my new clutch I put on an older 1 with yellow springs & it does the same thing. Not nearly as bad but this was initially why I swapped that out to begin with. Prob is there's no rev. When I start the bike it's ready to go. Like everything's already engaged. Now my new clutch is in it has yellow springs. Can I just not run yellows or what? My torque spring is red, 10g sliders. I've done this set up many x's on my other bike & no issues. Anyone know what would cause this or what it is?
Thanks

Alright so 1st I wanna say my 1st experience was what I thought to be an A/F prob when in fact turned out to be the ignition coil goin bad.
Now since then @ idle no matter how much I messed with throttle cable or turned throttle adjustment screw or messed with carb my back tire would spin & sometimes I had to turn the bike off @ red lights cause it just wanted to go. Well just a bit ago I was checking the valves & said eh might as well change the belt while I'm here.
So upon taking belt cover off a nice size piece of metal fell out & more little pieces. Oh imagine the surprise when I find out my clutch pad had busted off. Well the whole arm not just the pad. I have pics but not sure How to post here on iPhone.
Very dangerous!!
So I'm glad I found this when I did & hope this help some of you out there trying to diagnos a prob
Just remember If it's got symptoms for 1 think could be something else entirely

Alright so I was seriously about to abandon all hope when I did a search & found similar issue on this board.
Prob was ignition coil. Luckily I had a spare, idk if any of you have taken 1 apart but it consist of a spring a piece of flint (I'm guessing) then your part that plugs onto plug.
My case was "flint" was wore down to practically nothing causing an uneven spark showing air fuel symptoms.
It's fixed for most part! now I've really got to tune my carb.

Well after Changing out the jets a few times & tuneing the carb all the ways I know. The bike will speed up bog down speed up bog down then take off. I can't believe its the carb bc im running old carb exactly how it was b4 the change & it's still doin it. I've adjusted the valves & there a little loose. But again I've ridden with loose valves b4 & this wasn't a symptom. It acts like there's a tear in the diaphragm. I'm confused
