Here are the long awaited pictures. This is what started the whole episode:   A better look after I pulled the head:  What I've decided to do with my air filter, after the side airbox didn't pan out. Its using a bit of the original snorkel to the factory airbox. There was a glued joint that I was able to seperate in the rubber hose, so I can easily reverse this if I don't like it. I'm probably going to put a container around it, like Rich did:   |

I had one of the exact boxes pictured by scrappy as OE on my 1P57QMJ engine. Fits just fine, and did a decent job after some modification to open up the flow a bit. Uses the triangle paper filter with foam wrap. Has a small chamber to collect oil and a drain tube. No reason not to use this if you're using this box, as it works well. Good luck mounting a catch can if you've got one of these behemoths grafted on too. Mounting is similar to runningslow's positioning, although his box is different. Just want to correct, that's not my box in those pictures. That is Rich's. I was quoting his post. I ordered one just like the one in the original post, from Scrappy. It will not fit my scooter. Those of you say it fits (which I don't doubt you one bit), do you have long or short case motors? Because, if you have long cases, it could just be another quirk of my QMK motor. I think my CVT cover may be interfering some, but I thought my bolt pattern was the same for the cover as a long case. Perhaps I should take a picture with it with the bike show what I'm taking about. |

Rich, do you have any pictures of how the side mount air box mounts? Sadly, that's not the airbox that Scrappy is selling. |

Thanks for the replies. I would also like to see some photos or instructions on how to mount this air box. My original air box is now ruined so I must replace it. Well, I just bought one of the above referenced side air boxes from Scrappy. Didn't fit at all and I don't see how it will possibly fit a GY6 150cc long case. This must be for short cases. I'm going to return mine. |

Well, its been a few days and I got the motor off the bike, pulled the head and got a good a good look at what happened. I have some pictures and I'll post them later. Looks like I may have just overtightened one of the exhaust studs, because that's all that cracked. The combustion chamber and the rest of the appears to be in pretty good shape. I'm still planning to use the old head, because frankly its in one piece and I don't have to mend anything. But, I'll try to repair the broken one as a spare. I went ahead and ordered a new gasket set from Scrappy. The finish on the used one was wearing away and I just didn't trust it. While I was at it, I also ordered a side mount airbox to experiment with. I'd like to be able to use the space under the seat for additional storage. I also had another little snag when it came time to pull the engine. When I tried to disconnect my oil cooler lines, I had forgetten that I completely stripped one of the fittings, and this time around I started to strip the other. So.... I made an executive decision to just cut the oil lines, with the intent to replace them with new hoses and fittings. Once I had the motor on my workbench, I went to work with a brand new bolt extractor and actually managed to break the bolt extractor one the first fitting I tried to remove. Sheared right off. Now, I'm afraid that I may have to take it to a machine shop to get those removed. I also think at this point is the time when I'm going to undertake some body work and repaint the scooter. Get it ready for the nice cool winter riding season down here. The gasket set I ordered didn't appear to have the correct head gasket. The stud spacing was wrong. The side mount airbox will NOT fit on my scooter. In fact, I don't think it'll fit any long case motor. That being said, I did finally attempt to mount my K&N style filter and got it fit nicely using a bit of the snorkel from my original airbox. I'll take a picture soon. I may actually try Rich's tupperware housing, if I can find a container that I like. I managed to extract the oil line banjo bolts from the engine block by cutting the heads with my Dremel so that I could get my vice grips on them. After heating with a torch, I managed to get them to break loose. However... that leads me to a new point of discussion. I don't know how much anyone knows how the oil flows in this motor, but do you think there would be any adverse effects to plugging those holes until I can find suitable replacement fittings?? Lowes sells auto drain plugs with the correct thread and I'm planning to get a pair to use. I can't imagine it would be any worse than running a standard QMJ motor with a BBK, but I'm not sure if it would lead to oil flow problems. The thread in the crankcase is a M12x1.25. I'm having trouble finding a hose barb with that thread. I've managed to find some banjo bolts from specialty shops, but not the banjo fitting. I'd love to find a banjo fitting with a hose barb, otherwise I may to get some new hoses made with the proper fittings. Meh. |

Originally I didn't like the side mount air box. However, in the past year I've been converted and now prefer them. They're easier to work on and to clean up excess oil. Also, you get rid of the stupid serpentine airhose and ridiculously cumbersome airbox. You don't need a slight vacuum on the crankcase breather so you can skip the part of the system that pulls oil into the filter. Just use an oil catch can or tie the vent tube off high enough so that it doesn't dribble out. I have run his type of system on my scooters for years and never had any problems, but I change my oil quite obsessively. Sprocket will disagree on this to some degree do to water sludge getting back into the engine. Personally, I think this sublimates off and escapes through the vent tube. Plug the opening where the crankcase beather fits in and you should be go to go. Rich Rich, I don't really want to high jack this thread, but do you have any pictures of how the side mount air box mounts? |

wow will they redo it next year? I assume so. This was the 5th year, so I'll assume that 2012 is a go. (Although the website appears to have expired.) |

I prefer riding in the winter down here in Florida, too. Too damn hot and humid to ride for the most of the summer. Its fine as long as you're moving, but stop and go traffic is unbearable. Not to mention the fact that you're very likely to get caught in an unexpected rainstorm. You may have a put on a few layers on the cooler winter mornings, but I'd rather be bundled up than dying of heat stroke.  |

The new/old head should be waiting for me when I get home tonight. (Thanks jake!) Looking at my schedule, I'm thinking Saturday morning is when I'll finally start tearing into the bike. I'll try to get as many pictures as possible.
I'm going to try and reuse the head gasket, after a careful cleaning and using some Permatex Copper. Scrappy thankfully lists a QMK gasket set on their website, so should I need to go that route, I can. At least it appears that the gaskets won't be as hard to track down as a new head, heck he even has a piston & ring set.
I suppose this would also be a good time to try my hand at lapping some valves, too.

Woohoo!! Looks like I'll be getting my old head back from Jake, so I should be good to go! Though, I do still want to try repairing this one, if possible, since they're so freaking rare.
I swear, my next scooter will have a more common engine!!!

I'll take some pictures once I've got the motor off the bike. I'm not entirely sure what I'm dealing with myself, yet.

Well, Scrappy says he doesn't stock them, or even know of a factory that makes them.  I'm going to have to find time to pull the motor, then pull the head to look. I'm wondering if it may be somehow repairable. What are these heads made of? Cast Aluminum? Anybody have any experience with this stuff? www.por15.com/FIRE-SEAL-2000/productinfo/FS2/ |

Everytime I've asked Alpha Sports if they have parts, I get told they don't, even when they list them. The GY6-B heads also don't work. Too big.  |
