Hmm interesting ideas fellas- too bad I can't use the box of relays I already have for A/C stuff- but they're 24v  . I was originally thinking I wanted to be able to turn the fuel pump on/off independent of the ignition switch as I thought it might be causing me hard starting (I can currently start my scoot with the ignition switched off because I have the green cdi kill wire disconnected. Terminal #8). After I have my scoot started and running I turn my switch on (powers fuel pump) but now that I'm getting it all figured out I don't think it's the fuel pump causing my hard starting (well not the fuel that it's pushing anyway) but rather the way I have it wired... According to the diagram for my scoot (P200E w/key and battery after 1979) the terminal at the switch (#3) goes directly to the battery- but it also splits off and goes to the stator.... I guess it doesn't matter if I run a wire all the way from the battery + terminal- It'd be the same as tapping into terminal #3... Just gotta be careful I don't backfeed 12vdc through the purple wires to the stator again!  I did end up running up to Autozone and getting some electrickery supplies for the re-wire. I don't think this fuel pump draws much amperage but I probably will use the relay just to be on the safe side. Thanks for the suggestion fellas!  |

Be careful with that meteor piston,they have bad reputation of seazing during the brake-in. I am running a Meteor piston on one of my Malossi 70cc builds. I have 25 hrs on it so far and not an issue yet, break-in or otherwise. |

Relay install complete! Terminal #6 on the key switch goes unused but it does supply 12vdc when key switched on so that's what I used to trigger the relay. Power is straight from the main 12Vdc+ wire that goes straight to the battery. Now just to fish a wire through the frame from the relay to the fuel pump and badaboom badabing should finally be good to go. I'm so close to finally having everything working correctly I can taste it! Poor 150cc flip scoot is growing cobwebs haha.  |

That should work and you probably could hook your under bike and wheel well LED strips there as well!

There will be a day you can ride it like you stole it.  I tend to chamfer the ports more than most for that reason. |

I painstakingly chamfered every single port in this cylinder (there's a lot!) and this last round even got ball honed...  |

What a PITA it was to fish these wires through the frame! I actually was smart enough to run the additional CDI kill wire at the same time. For some reason that green wire that runs from the headset to the CDI at the rear always corrodes and crumbles on the P series bikes. IDK why but it's extremely common. It'll be nice to finally shut the engine down properly! I struggled for about 40 minutes with a stiff piece of wire to get it through the frame. After a few minutes of Googlin' I found a lot of folks like to use a bicycle brake cable to get the job done. I'm not about to cutting up my bicycle but I did have to finally sacrifice an extra intact Mina rear brake cable I had. Once I cut the end off of it and had a nice thick cable to work with I had it fished through in about ten minutes. Got the wires from inside the fuel tank area to up front under the horn cover...  Then I reset and got the wires up through to the headset! Yeah!  Phew. It's getting late and I'm soaked in sweat so I'll leave it here until next time...  |

It's looking pretty good. I like the antique plate  |

Okay, I'm caught up now. Highly interesting thread. Not that I understood a whole lot of the technical stuff.
I do run a 2 stroke myself, as a matter of fact. But it's a very cheap, very primitive engine and I've never made any effort to upgrade parts and performance. And this thread is a very good demonstration of just how much frustration I could expect if I tried.
But I still love your bike, Niz. And I'm rootin' for ya. I don't doubt that you'll get it together in the end and have a bike that'll be your pride and joy.
And I'll watch your progress.

I do have another scoot and a whole build thread on it too here.- it's a 96cc Minarelli. I also have 27 "flip builds" here too. This vintage Vespa has been the most challenging by far! |

Unfrickingbelievable. This happened at a high idle while I was checking out my electrical system. The brand new Grand Sport piston just simply broke. Guys, I don't know how much more I can take with this engine and this scoot. I'm thinking about selling it and getting my weekends back this is just too much...   |

Don't sell it! You'll never get one back. Drain the gas push it aside and come back to it. But don't sell it. Any possibility of warranty replacement. That fu***ng sucks. That's the luck with my Keeway, fix one thing then it's something else. Unless there was contact that skirt should not have broke. It the con rod bearing OK?

I suppose you're right Ryan- I've just put so much time and effort into this blasted thing it's maddening that I've really only gotten one or two days of decent riding out of it. Just last week I took my daughter to her friends house on the back of the AIR scoot. She asked me "oh this thing still works??" Haha yes it still works. I just never ride it because I spend all my time working on that cursed Italian machine. I wonder if the $$ spent here wouldn't been better off going to buying a Polini Big EVO for the AIR. Ehh probably have nightmares with that too... I'm looking at tearing the bottom end down again to remove all the broken aluminum. New gasket set in the least and new bearings and seals and- of course- new piston.... Grrr.... I'm seriously thinking about just saying "F it" and running the piston the way it is. It's not like the lower part serves any function (besides stabilization!) of opening/closing any ports or anything. What's the worst that could happen?? I've already been through it all with this thing haha. |
