The interesting thing is that when I check the clearance and tighten the adjuster bolt down, the whole thing still rocks back and forth. What is on the other end up in the valve that holds the whole rocker arm firm? Is there a spring?

I am in the middle of adjusting the valves and noticed on the exhaust valve the rocker (the part that you adjust - see attached pic) rocks in and out towards and away from the spring. The top valve didn't seem to do that. Is that normal? Is there a spring on the other end of it? Attachments:

You can also actually get those rubber grommets at Lowe's in their hardware section in their specialty fastener drawers. They are along with the plastic wing nuts and plastic bolts. I did the nuts and washers too (not too fun) like sugerscoot and when I went into Lowe's for something else I found them there. They're pretty cheap. I actually went back and replaced my nuts and bolts that I had already done with new rubber grommets. So much easier.

Hey guys, I'm hoping I can get some help with this. I have a linhai 250cc scooter and I was riding awhile back and the engine started running really hot. The fan wouldn't come on. I was quite a distance from the house. I checked the coolant and it was low so I added. I got it home after several hours of riding and stopping to let it cool and riding a little more, stopping etc. At one point I lost power for a short period of time. It came back but now my scooter has a slight knocking noise in the engine. It's almost exactly like in this youtube video even though that's a different bike.
I'm hoping I didn't destroy my bike. I did figure out that I had a pinhole in one of the heater hoses. I have replaced that. I haven't yet been able to get the fan to kick on after purping it several times. I'm not sure why yet but the knocking noise has me concerned even more. I have no lost power at all when I take it around the block. It just knocks. Does anyone have any ideas? Any help is really appreciated.

Hey JR - hope this isn't a dumb question but couldn't find it anywhere. Can you explain your process for "burping" the coolant system. I have a Linhai 250cc scooter. I just had to replace a radiator hose and want to make sure I get this right.

Just thought I would mention that the issues all appear to be resolved. I drove it today on a 40 minute drive to work. It drove like a charm. I have added the fuse for the 12v plug on the positive wire to the battery and it works great. It was nice to be able to charge my phone this morning on the way to work. Thanks again everyone for the assistance. Happy to be back on the road.

It's all put back together and I took it around the block several times. NO ISSUES!!! I think in retrospect it was either the fuse holder for the 15a fuse or the remote start or both. There were several wires that could have possibly been the issue. I don't really know. In the end it was good to spend the time to meticulously go through it all. I did move the remote start to a place where I can plug it in without having to take the front off again.
I did run the wires from the front to the back for the 12V plug and hooked it up in the front when I was putting it all back together. I didn't hook it up yet in the back until I get the inline fuse but at least it's there and that's simple to do.
Damin just to clarify, should an inline fuse go on both the positive and negative wires? Thanks again everyone for your help. Very much appreciated.

First of all thanks for all the help. I appreciate all the support. I have been a member of lots of forums and seriously have gotten a ton more help in a shorter period of time here. Hat's off to you guys. There is a ton of good information here.
Here's what I have done. I went ahead and replaced the fuse holder. Figured it didn't hurt since I already had it open and it only cost about $3. I went through the wiring harness and removed all of the small pieces of electrical tape around all the little splices and redid them with liquid electrical tape. Again a cheap step that couldn't hurt and could potentially help with a problem I couldn't even see. I went through all the wires in the steering tree. I did find a green wire that appears to come from the kill switch that had a section of its coating rubbed off exposing the wire. Tried to short it out by touching it to something with the engine running. Couldn't get it to short anything out but figured it would probably cause some issue and could be the problem either way. I coated it with liquid electrical tape. I also have unplugged the wireless starter. Thinking about moving that to the glove box where I can plug it in but can easily get to it if it causes problems in the future. I think I'm going to put it all back together and hope for the best. I can't find any other issues in the wiring. If it still is a problem my thought is it would probably be a component like the remote start, the regulator, the starter solenoid, or possibly the brake switch.
Lastly I bought a 12v plug to be able to power up a gps or charge my phone while driving down the road. Was planning on putting it inside the glove box. Will that work and if so where is the best place to wire it in? Thanks again!

This has been crazy. I got everything down to basically the frame. I have the wiring harness all opened up. I have gone through every wire and connection that I can see and I still haven't found anything that convinces me what the issue is. There was one wire going to the carburetor that had the clip on it broken exposing the wire. I have fixed that. Not sure if that is the issue or not. It has been so tedious and time consuming getting everything taken off, I am leery of putting it all back together without knowing that I have it fixed.
Can you explain a little what the CDI is? I'm not sure what I am looking for. There are 2 black boxes in the back above the muffler. A lot of wires come out of them. Is that the CDI? Sorry if I am asking dumb questions, I am just new at this.

I went over the entire wiring harness and didn't see any issues. I even reconnected the battery and started the scooter. I went through every connection in the front with the motor running hoping it would short something out while I was touching it. Nothing shorted out. I have unplugged the remote start since I don't use it that much and don't really NEED to use it. I have read elsewhere that some guys have had a lot of issues with that unit and it kept blowing fuses. I'm going to look at all the back connections as well. I'll keep everyone posted if I find anything.

So I got the front off. Started looking around at all the connections. Haven't looked at everything but there was a bare wire in the black wire coming off of what appears to be the left speaker. There are 2 of these in there - one on the left and one on the right. I can't believe that would cause the major issue but I'll keep looking.

I've heard of the remote start causing issues. Can that be disconnected?

I have a 2007 JCL MP250A scooter with about 600 miles on it. I have had no issues with the scooter so far and love riding it. Yesterday however I took the scooter on a ride and it died in the middle of the road. The starter button wouldn't do anything but the dash was lit up. I attempted to use the remote start after which everything went completely dead.
After some digging I figured out I had blown both fuses in it - the 15a fuse next to the battery and the 20a fuse on the starter solenoid. I replaced the fuses and went out for another ride. Got about a hundred feet away and it did the same thing. I didn't use the remote start this time and the 20a fuse didn't blow. However the 15a fuse did. I have replaced 3 15a fuses so far and cannot figure out what is causing them to blow so easily.
I thought it was an issue with the rear break switch because it seemed to happen when I was coming to a stop and pressing the brake handle on the left. Didn't seem to happen when I used the front brakes only. I can't however get it to do it when I am in the driveway and pressing the rear brake switch.
Does anyone have any ideas?
