I recently got a new crate motor from scrappys along with a 83cc BBK, which was installed by the local scooter shop here. After bolting everything up and kicking it over a few times, it fired up. purred like a kitten you could say. I let it idle for about 20 mins like numerous ppl have said to let the new gaskets and such heat up and "melt" to make a good seal before I gave it any gas (by that I mean throttle, obviously it was getting a little gas to let it run...)
So after that I did a few laps around the parking lot at my work to make sure it was good to go as I would rather have any problems happen there rather than in the middle of the road on my way home, leaving me stranded. It seemed to run ok, although the acceleration acted a little funny. What I would describe as "stuttering". About a half second of lots of power, then a half second of nothing. Not less power really, just kind of a flat spot, followed by another half second burst of power, and so on...
As my scoot has been out of commission for about 2 months now and ive been relying on co-workers for rides, I was about to take my chances with it and ride home. Was SOOO looking forward to being mobile again! I figured id work out the bugs shortly. So the parking lot at my work is fenced in and the last one to leave has to close and lock the gate. I left the bike (trike really) running to lock it up as is I was going back to the scoot, it bogged down and died. I spent about 10 mins kicking it over and nothing...
At this point I want to say that the reason Im kicking this thing is that the starter on the new engine came with 2 wires coming out of it, one leading to one of those plastic plugs, which my scoot didn't have, and another which for the life of me I cant remember exactly what it was right now, but I want to say is a ground. I just know that the original starter I had had only one wire coming out of it that led to an eyelet, that hooked up to a "thingy" (because I don't know what to call it) next to the CDI. That wire is a negative I suppose because its a black wire and the other wire on the other side of the "thingy" has a red wire hooked up straight up to the battery. So I figured the best option was to put the old starter back on with the wire I figured would work. It didn't. And I hold the brake, hit the start button, nothing, not even a click. like I said, I figured it was just another bug I would fix shortly. I wouldn't have minded kicking it a few days as long as I had wheels under me to get around.
So after kicking it a while and trying to figure out what was up with it I looked at it and noticed that one of the grounds had come loose (off) while I went on my little test ride. A little green one that was part of a pair that grounded to a bolt that holds that little elbow between the carb and the engine itself. I also noticed that another plastic wiring clip was disconnected. two little wires which I know I hooked up at one point, but as everything was coming together I had to disconnect to move around the frame out of the way, and im not 100% sure I reconnected, but pretty sure I did. but either way, connected or not, that was the way it was when the engine first ran, except for that ground that came loose. I should have taken pictures of this before I left to give ppl I better idea of what talking about.
I work at a body shop, painting cars (or motorcycles, or planes, or anything really, as long as it can be sprayed with a gun) and sometimes we get a car that has been taken apart for us to paint a core support (the main front structure of a car that holds the radiator, front bumper, and usually the headlights on, which the hood locks into). some of these cars (toyotas and BMWs especially) have a thing that if certain grounds arnt hooked up, it will fry the whole wiring harness. Its a big deal around the shop to make sure that those kinda cars don't even get the key put in the ignition. just turning it on (not starting it, just turning the key one click to the on position, will fry it) a new Toyota wiring harness will cost you around $1000. that's parts. if you're a weekend mechanic and realize you f'ed up, I cant even imagine what the labor rate would cost you to replace one by a pro.
My main point/question here is that is it possible to fry a scooter wiring harness? Im definitely getting compression in my motor, can feel it when I kick. Im thinking its electrical at this point. but it failed after I locked up my shop, my boss doesn't give out keys so I couldn't get back to my tools to investigate much more. it might be something so easy as checking the main fuse or whatever.
I also will apologize and give props to anyone reading this line. Most of my posts on this forum have been lengthy, drawn out, and pretty much considered rambling to most ppl, so thanks for hanging in! but I think when you get on a forum like this, asking/or pleading for help, there is no such thing as thing as too much information. so that's what I try to give.
About everyone this forum rocks!
If you need your scoot painted up professionally... hit me up. I can give u a deal. And I mean professionally. not that maaco slapdick crap!
