Ok, then my well must be a little bit bigger, but I'll have to measure. They don't make ANY contact at all.

I would think if your wheel has a well that drums should work, could the supplier have sent you the wrong size? I asked Rick at Scrappy Dog about it. He told me that there two sizes of shoes for a GY6: one that fits the 50 and one that fits 125/150. My rim has the "well" as you call it, but it appears that it may be too large of an opening. When I get the chance, I'll pull the wheel off again and measure it. I looked at few parts places, and it looks like the inner diameter of the "well" should be 130mm. One thought, since I've never had another scoot apart to look, is there some sort of lining that would be inside that well, i.e. the actual brake drum? |

Do you think I could splice the brake hose back together, like I did my with oil hoses?
The pressure is surely going to be higher, but I don't think enough to worry about. Heck, if the brake lines fails, it'll be no worse that how the bike is right now...

Thanks Larry. I know it probably wasn't the wisest thing to go out with only front brakes, but my logic was that front does 70% of braking anyway, so I figured what the heck....  I'm hoping its just a matter of getting different brake shoes and I'll be good to go. If I can get replacement hoses, I may consider going back to the disc brake. I could probably just take the remnants down to Autozone and see if they have anything that'll match up. As for the body, plastic welding is definitely the next step. I'm hoping the plastic epoxy will hold up, since it says it works on ABS. Thankfully, everything I've attempted to fix so far was just cracked, I wasn't trying to replace any missing plastic. As I've said before, I've got a lot of repair to do on things like the front fender which is actually missing plastic. Those are going to come later and will definitely require different techniques. |

UPDATE: Some of the plastic is back on. When I went to put some of the pieces back on, I notice a few more broken tabs. So, I tried to repair those with some plastic epoxy. I'll probably try fitting those pieces tonight, now that it will have cured. Regardless, I rode to work this morning.... this is a great feeling! ;D No apparent running issues. I'm pretty sure she's running rich, but I'll have to pull the plug when I get home, because I wasn't smart enough to pack any tools. Concern: I'm only running on my front brake. Even when fully engaged, the rear brake shoes have no bite. The wheel spins freely. After looking around online, can someone confirm that there are different brake shoes for different wheel sizes? I have 13" rims. I'm wondering if the shoes I have are just too small and I could get larger ones, or if my wheel won't work with drums at all. I could probably go back to my disc brake, but I'll have to replace the lines... since I cut them in my haste.  |

Now that your getting to the end of your project I just want to thank you for documenting everything. Its been fun and interesting to follow along. Oh, project isn't near completion... its just beginning! Now its time for upgrades! ;D |

I must be dreaming.... my scoot its running!! That's all for now... I've got some riding to catch up on! (Actually, I need to start reassembling the body and figuring out the brakes. :  |

Woot! I supposedly have a box of scooter parts at the house waiting for me! I know what I'm doing tomorrow! ;D
I've also put in an order for a Sigma BC509 Bicycle computer that I'm going to use as a speedometer. That should be here sometime next week. I'll try to document the installation for the benefit of others.

For me, a ride to Brandon is a day trip in itself. I live about halfway between Orlando and Lakeland.

We need to take all your posts and make a tech manual out of it Josh. Good luck! Thanks. That's along the lines of why I've documented the whole process... so others can know what I went through!  Its been slow going, I think I see the light at the end of the tunnel... I just hope it isn't a train!  |

Rich, its more that I'm not a big fan of chrome in general. The cover itself isn't bad, and I think with a good polishing it would really shine. However, I want to keep the UM branding (even though as a company they screwed me over) and I've got some paint ideas I want try on that cover. As for the oil cooled GY6, you are correct... that's the radiator. The system is completely passive, with no fans. The oil is just pumped through the radiator up front. The QMK blocks are cast with oil pathways that feed the hoses to the radiator. I'll refer you to an older picture from my motor disassembly where you can see where the hoses attach.  They're right below the cylinder on the front of the block, you can see the head of one of the banjo bolts. Its one of these bolts that I could not extract from my new motor to swap out the oil hoses. If someone is really interested, I could probably take some close up shots on the new motor. For a non-QMK block, obviously this wouldn't work well. But, you could probably fashion something similar to the Good Dr. JR. ;D |

I am getting ready to put a new top end on my 50, I think I will pull the motor, for ease and cleaning, everything works mechanically, but I think after 8k miles, it is tired of breathing properly, no longer will fire. I orded a compression tester, we shall see. I will continue to follow the Matrix. Tom Cometman Thanks for watching!  Here are some pics I took this weekend. The camera lense had fogged up a bit, so that's why there is a haze. So, this is how she looks in the garage at the moment:   As I said before, I'm not a big fan of the chrome CVT cover.  This is the factory CVT cover I'm going to put back on it, once its gotten a new coat of paint.   Once she's up and running to my satisfaction, I'll start work on reassembling the body. I've got some body work and painting to do. |

Just placed an order with ScrappyDog: New 11 pole stator, orange coil and cdi, and a brake lever assembly and cable to use the drum brake on the new motor. Plus a new front brake lever, because the original one broke when I dropped the bike over a year ago.
I'm also going to get myself some feeler gauges to adjust the valves and buy some gasket material to do Rich's enricher block-off mod.
Hopefully I'll have it all before the weekend! I want to ride this thing!

My scoot came with one from the factory. I got about 9000 miles on it before it died, but I probably could have taken better care of it. I just installed a new one, similar to it, that I got from ScrappyDog. I ran it for about 30 seconds before it died. I lost all spark, but that was nothing to do with the motor and everything to do with the old 11 pole stator from the original motor. I'm waiting for my next payday (Thursday) to stock up on some new parts to get her running right. The Good: - its a 61mm cylinder, so its 168cc, not 150 - oil cooler - ability to install BB kits larger that 61mm without having to machine the case. - performance (although, I don't have any other reference for a 150) The Bad: - Its not a V8 Bottom line: Take good care it and it should take good care of you. I don't think you'll regret it, but do know that every motor is different. My 2 cents. |

Sorry to hear about! I'm glad you're not any worse off than that!
Here's to a speedy recovery!
