Yeah, it's pretty sad. It really makes me appreciate my 2 strokes. I pretty much knew it was gonna be slow though. I mean, Bob's 140lbs on his old 82cc couldn't keep up with my 280lbs on my stock 49cc Triton up top. He did take off faster than me till about 30MPH though. The scary part is, the 2 strokes are becoming few and far between. My initial hope was for 40MPH cruising with 200+lb riders. There is hope for that at least. I haven't touched the transmission yet. I wanna get the carb at least mostly in tune first. I'm starting to wonder if the idle will ever be normal.
I have figured out that there is power to the headlights coming out of the high/low switch. It gets lost somewhere between there and the light's harness. I hooked power to the light's harness and it will light up. Just gotta bridge that gap.

I straightened out the wiring and fired the scooter up. No headlights. Jiggled the connecteor to the headlight around and it lit up. Alrighty then... I have a box of connectors from my Mustang cleanup project lying around, so I modified a connector set to be only 3 wires and used it. Now my scooter is part Ford.   The headlight does work... but the switch is crappy. You have to get it in just the right spot or it won't work. It appears to stay in one spot though, so it will do for now. I should probably take the switch apart and have a look inside.  It is supposed to rain off and on all day here. It rained hard early and quit for a little bit. I figured I'd let the road dry up and from the looks of the radar I'd have time to get at least one run in to check the tune out again. I finished the wiring less than 5 minutes too late... now it's raining again. |

I went 39MPH through the radar trap. Then I came back and swapped in the Naraku High Speed Variator with 5.8g rollers (stock were 6.5g)...  1,000RPM contra spring that came with the Naraku variator...  2,000RPM clutch springs...  Now it revs like crazy just to move, and then takes off about the same or slower than stock. The it revs hard all the time at any speed. I passed the radar topped out at 34MPH. The idle is still erratic. It still randomly wants to die after giving it gas. Sometimes it's fine, sometimes it's not. On top of all that, it blew a fuse and now it blows fuses instantly. O M G . The more I mess with it, the more I hate it. Junk would be an understatement at this point. |

Now the radar is messing with me. It said I was doing 26MPH on a downgrade. It's slow, but I think it was back to the 35 range after going back to stock clutch springs and the stock torque spring.

Time for another bike speedo. Im sure you will get the bugs worked out. It seemed to me the more my kit broke in the better the idle got but i still have a steady idle problem. I think its just the 8 year old tired stock carb because i have tried everything else to get it to idle smooth. I can lean my scoot to one side while sitting still and it will stumble and act like its going to die. I have checked everything, the float level is correct, and all the rest is good.?. The boost bottle helped allot, put wanna them on there.
I dont think i will ever take up a retro scooter unless its a very good deal, or a 2T. With all the trouble your having i thing i will steer clean of the retro. Just the plastic alone was enough for me, i like my scooter to have panels that are fairly easy to remove.

I've got a bike speedo here, but I'll worry about it last. Radar is 2 miles from my house right now. This idle is beyond a little idle problem. It's riddiculous. I think I underestimated it saying 3-400RPM surging. The retro itself isnt a problem for quality. The customer scoot I worked on was OK. It does suck to remove a bunch of panels to do anything though.. plus no clearance in the tight little frames... plus they don't fit well if you are anywhere near 6ft tall I'd guess.
I think the problems with this one is that some knucklehead played with it. Somebody's been tinkering with the wire harness doing weird stuff for no obvious reason. There was a ground wire spliced into the headlght positive. I fixed that earlier today. I stripped the bike down again and pulled the wire harness out after realising there was a draw on the battery. It completely killed a brand new battery. It's been on the Battery Tender for 6 hours and it's still on red with the battery out of the scoot. It's still popping fuses. I stripped the stuff off of the harness to look it over. The turn signal flasher has 3 wires to it in 1 harness. Someone cut the ground out of each side of the harness and then soldered them together to bypass the connector. The connector has continuity, so I don't see the point. The green wire for the stator is missing. It's been taken out of the connector. Just weird stuff. Was this some kid's science experiment or what? I'm looking for a new harness. Between loose connections, stiff/burnt wires, and all that stuff it looks like build or buy a new harness if I ever want it right. I'd build it, but the connecters are half shot, so I might as well buy it. I can't find a Sunl specific harness though.

What a nightmare! I hate,hate,hate wiring messes, the looks alone of a wire mess can be to much. Glad to see its got Ford in its blood now. You should put a Ford sticker on it somewhere. I bet the discharge problem is what is causing the funny idle. Could be robbing a bit of power too, lets hope so anyway. I bet nobody looks at the stuff i have sold over the years and says to them selves "why the hell did they do that?", at least i hope not. I was down at my cousins the other night and we were standing there looking and talking about a old GS750 he got real cheap. He said the man he got it from told him it ran but had a wiring prob so it got parked. I looked down at 2 pretty good size wires that ran close together and saw that they were burnt together after i turned them over so i would imagine thats the problem. It looked like the seat rubbed the insulation off one. My point is, i wish everybody that doesnt have a clue one what to do when they have electrical problems would just LEAVE IT ALONE! In my experiences with wiring ten out of ten times its messed up worse from somebody messin with it. Thats why the big companies wont honer a warranty if you break the seal.
If i ever get a little retro that isnt a 2t already i will try to put one in it lol. I dont know though, it seems the motor is fine on the one im working with its everything around the motor that sucks lol. I have had good luck with 2T,s all my life. I have never blown up a 2T, i have worn em out but never blew one up. The first one i wore out was a 83 Honda Express when i was 14. The piston and rings were worn so bad the compression went to pooh. At the same time a local shop was throwing one just like it that was stripped of most anything good but still had the motor, at least the piston and cylinder. So i went and got it out of the dumpster and took it home and fixed my Express. I road it for another 6 months, sold it for $100(what i paid for it), then got it back for free 3months later. The dude said it blew up on him as he was dragging it across the road. So i took it in the garage and looked it over to find it was out of oil because of a broken oil line. I fixed the oil line, took the head off and looked at the cylinder. The piston wasnt stuck so i oiled the heck out of the piston and cylinder and put it all back together and she fired right up. It starved for oil enough to not start but not enough to seize. I road it for another 6 months then traded it for a nice bike. Then i bought a 85 Honda Spree and wore the piston out on it so my dad bought me a new one (factory bore) and i put it in without boring or honing and rode it for a year then sold it.
Sorry for rambling, i just love the 2T scoots. It sucks that they are getting rare, i remember laughing as a kid when one of us said could you imagine if they made a four stroke 50cc lol. If i only would have known.

I just talked to Bob. He said he's gonna find out if the previous owner knows who worked on it. I don't really care who it was, I just know this is not factory stuff and someone's a moron. You cannot just put wires wherever you think they should go. If you are trying to rig something up, you need to do some tests, not just install it and deal with whatever happens. Wiring is the worst. I'd rather work on the engine/trans/brakes/frame anyday. I ordered a new harness, light switch, starter bendix, belt, carb, and headlight assembly. At this point I'll have about as much as a new scoot in it. I have repaired or replaced nearly everything on this scooter. I didn't think I could sell it for half of what's into it, so I might as well finish it. I think I should put decals on the sides of this scooter that say "EPIC FAIL".  The 4 stroke 50 is definitely a laughing matter... at least once you get used to 2 strokes. I hate to badmouth them so much. I mean no offense to any member that owns a 50cc 4 stroke, but I suggest that they try out a good 2 stroke scoot (not the D1E41QMB that is chain drive and tops out at 30). |

Still waiting on the wiring harness and switch from Parts Pro. They shipped it out quick, but used FedEx. I have terrible luck with FedEx shipping times here. My local FedEx facility is really bad about rescheduling delivery. It really sucks when an item should be here Friday and they'll reschedule till Monday.
Oh, and the headlight was out of stock. It'll just have to stay yellow for now.

Have you tried polishing compound on the h-light lens? I know it works pretty good.

Yeah. It looks a little more glossy, but it's still terribly yellow. I'm pretty sure a yellowed housing plus standard 35W lights is gonna be pretty craptastic. I'm used to 55W lights in a nice housing and I still think they could be brighter ideally.

I was sent an email from Parts Pro USA saying my order for the wiring harness was shipped July 26th. I emailed them today looking for a tracking number, thinking Fed Ex may have screwed up. Turns out they never shipped it out. It took the better part of a day for them to even figure out if it had shipped or not or what was going on. My order finally shipped today from TX, so if I'm lucky I'll have it late this week or more likely sometime next week. If I made a blunder like that and took a week and a half to ship something I'd upgrade to faster shipping for free, not them. Awesome.  |

pathetic! Fed-ex sucks! and most of our country,s buiss end of shipping is lame as hell too... It becomes real obvious when parts ordered from overseas gets here faster than international orders. Dang lazy Americans lol.
Good thing its not a customers scoot.
Hope ya get em soon Vert!

I got the harness in. The wiring for the controls is wrong. This one uses no ballast resistor, but it's got a 3 pin connector that looks like the same 3 wires from the stator that plugs into nothing. I can't find anyt missing electronic components from looking around Roketa's diagrams though. I jumped the terminals on the starter solenoid with the key on and it will run. I just have no lights, electric start, signals, etc... I don't even feel like touching this thing now. Every time I mess with it, something else pisses me off.

I ordered both handlebar switches from Roketa as well as a new flaser that will just plug in instead of the spliced one and a new headlight assembly. I got the order in today, but it's only the flasher. The one part I could of easily replaced with a normal flasher if I wanted is all they had. The specialty parts I need are all out of stock and cancelled. I really understand some peopl'e low opinions of Chinese scoots now. I used to think they just didn't know where to look for parts, but I've got quite a list of sites I know to look on and everything is out of stock at the couple of sites that even say they carry these parts. I shoulda called this thread "Sunl SL50QT-16 : Polishing A Turd".
