..., the little computer fans would be a joke and waste of time. Gotta Flow some CFM I'm unsure if your Scooter Electrical system will run it for long. I got some fans that BLOW and use very little resources. I can figure water-proofing the wiring but the fan motor itself would become the rub. Electrics are good and pushing at rates (not sure haven't checked inna while bit charges battery and runs all lighting for three years). Same battery and wiring... well a little splice with solder here and there. Just thinking airflow and have some ideas (apropos to the situation). Thanks for the comments... will figure something out: Got a little spare time once in a while and this is my partner/girl-fiend/hobby. It is my ride. LOL Peace and safety to all and be blessed... don't forget to bless others. Edit: I like the idea of passivity as an alternative. Thnks; sure it will fi tn somewhere. |

The real cooling of the return oil comes from the airflow around the timing chain area where the oil pumped up through the cylinder and head returns to the sump. Thanks... this gives me something else to consider. Never had an issue but this is the first summer for this "80cc" engine and prolly just paranoid.... |

Instead of a gaping hole  I was thinking of installing a bigger (one imaged is a mock-up) case-fan from a desktop PC. i74.photobucket.com/albums/i249/r4d1c4l/1_zpsdglwb4aq.jpg Points basically at the valve-cover so would forcing a little more air over the cover and surrounding area drop temps at all? Or Forget about it? I leave the door off to let extra air flow. Would have to maybe countersink and put the cover over it in the rain. Or silicon. Doesn't the flung-off oil get caught by valve-cover and return to reservoir? |

Angry and depressed... that's the feeling. Really sorry, bro.
Hope this mess turns out well.

Love those big wheels on the Punch... remember riding one years ago and it was a smooth ride compared to these 10 inch.

One other thing... This is how I keep the case bolts organized.  Thanks... forgot where that metal piece on bottom left went. LOL Can put it back on now (friends bike). |

In the video thats some pretty odd colored gear lube and almost looks like Gator Aid or Green Slime dripping down from above. If that was a water cooled bike I'd almost think it was antifreeze. Thought that was just me.... Looked like more than what is actually inside the gear housing. Is's all over the tires. OMG. LOL Had to watch it a couple more times. Look for cracks and holes in the casing if it is not missing bolts, drain plugs, loose/missing hoses and seals are intact. Thanks for that video. Interesting.... |

May not be able to elaborate... but if it is sparking after shut-off: It is not shut-off: Maybe contacts shorting in the ignition switch or other electrical locations. Or there is excessive heating maybe pre-ignition? If there is fuel, ignition (spark or something acting like a glow-plug) and compression; the engine will continue to run until one is interrupted. Never had a scoot that did that but just throwing out something that may be helpful. Tired and going to sleep. Check back and see how this goes. Night, all. Thanks for everything...for real. |

All is well with the build. Guess all that "smoke" could have been unburned gas or vapor (from valves not seating/closing completely)?
Got some clanking under heavy load... think it is a loose (worn) boss-pin in variator. Had this noise before on a different build and a new variator assembly work it out.
For some reason the auto-enritcher does not seem to do it's job... tried two known good ones. Starts without issue and runs good. Anyone had an issue with auto-enritcher after installing 47mm "80cc" BBK? Or any other build? Just don't get it: Wired right (AFAIK).

Was that a new head that you put your old valves into or did you reuse the existing head when you installed the 72cc BBK? The 72cc (just checked eBay purchase and says it's 80cc - 47.7mm - not good with doing the math to come up with actual CCs) came with new head with valves pre-assembled. Ran it a while today and no smoke... may have a bit of an issue with pre-detonation now as when I give it gas (hard) I hear some knocking or pinging. Will try richening up tomorrow and see if it helps. Seems as if there is a bit of hesitation around 1/4 throttle but take-off is quick and low-end is screaming. lol Think the clutch is worn out and will slap a newer one on as well. @ pisonguy: Yeah... thanks for the input on machining the heads and all but it only cost like $50 and it was all a "get a donor scoot running" type of project. Refusing to put out thousands of dollars on some unknown metal that may or may not last long. Lapping the valves did the trick, though. |

I cannot strongly enough advise against putting a nut on top of your shocks. Some very serious injuries have resulted from such shenanigans. Thanks! |

That engine died not long (maybe a week) after posting this thread.... LOL Just lost all compression and would not start. Thought I had burned a hole in the piston or rings had become digested. Finally got the time to tear it down... talk about procrastination.  That not lapping the valves is most likely the issue. Don't know yet but will install to a ready-for engine chassis tomorrow and find out. Exhaust valve was not seating, toasted and a divot had burned (whatever) its way into one portion of the seat ( lots of leakage coming from intake and exhaust. Tried lapping but still had the tinniest bit of light shining through the burned spot and the excessive hiss on compression stroke got on my nerves. Prolly would have run fine but OCD kicked in. Pulled a valve from an older head and lapped it: Takes some quite a bit of effort to turn the crank now and hiss is almost non-existent. Lapped both intake and exhaust, BTW. Moral of the story? Lap those valves, Ladies and Gents. Don't get too hasty to get that ride on the road. "A stitch in time saves nine"? As always: Any and all input on this is/was greatly appreciated. Sorry I am slow to post and help out here: Lot going on and it ain't all good. Long as it ain't all bad; we good. |
