80cc Bike Engine Conversion
Has anyone actually ordered one of these, can you comment on the
quality/completeness of the kit? It seems like a decent price, since it seemingly includes all the handlebar controls, mounting parts, and a gas tank. Link: http://www.kingsmotorbikes.com/home.htm best regards, Martin |

I am personally interested in such vehicles, and found that site during one of my frequent searches. I posted the question to this group, and this group alone, because as a longtime participant I have read discussions indicating that we have quite a few guys with experience motorizing a bicycle. These are the type of people likely to have checked out the item for which I supplied a link. In looking at the engine kit (did you check it out, or just give me a knee-jerk reply?), I thought that it offered quite a bit for $160. For example, the resurrected "Whizzer" company here in Dallas wants about $700 for their engine kit. The Whizzer components are manufactured in Taiwan. I assume this $160 kit is a Chinese knockoff of something, and I was genuinely hoping to find someone who had been brave enough (or maybe lived near the supplier) to check one out. best regards, Martin |

FWIW Here in Colorado anything over 50 cc's requires a motorcycle license ,
insurance and registration. I don't know where you plan on using it but something to think about. RellikJM "Martin" wrote in message ups.com...

I imagine there are lots of applications. Many folks have a motorcycle
license, and registration/insurance for a moped is not expensive. On the other hand, I can imagine scenarios where one would not bother, such as using it to cruise the non-public streets of a large RV park, etc. Of course, you could always pedal it anywhere (no license required to carry an engine around as dead weight) and use the engine for assist when you think violation risk is low. I don't think the 50cc restriction is universal. For example, when I was a kid in Tennessee, the dividing line between "motorcycle" and "motor-driven cycle" was 5 HP, regardless of displacement. We all rode 90cc Honda motorcycles when we were 14 (moped legal age), thanks to an enterprising dealer who installed (easily-altered) throttle blocks above the carburetor slides and certified them as 5 HP.

Thanks for the links. From the reviews, it appears that there may be some issue with piston galling and seizures. Maybe the chinese aren't that careful what metals they allow to rub together. I note that the ebay seller offers complete replacement engines for $80, though. What a deal! Martin |

Martin Much of this galling problem has to to do with two lubrication problems as opposed to quality problems. Some people use the wrong oil, and most people make the mistake of using the manufactures recommended ratios. These ratios are intentionally weaned out to satisfy the environmentalist. After cooking a brand new leaf blower with 40 to 1, I switched to 16 to 1 (or 20 to 1) on everything,across the board, old or new. 5 years later and I have not had any problems with string trimmers, leaf blowers, and chainsaws. |

The oil I use is called Opti-Lube or some thing like that. It has Opti as the first part of the name. When used according to the package directions the mix ratio is about 100 to 1. It works very well. I use it in all my 2 stroke motors. Chain saw, outboard, etc.. I called the company when using it for the first time several years ago and spoke to the company president. He told me that he collects antique outboards and he uses the oil at 100 to 1 in the old motors. They will replace any motor that fails from lack of lube, such as galling or bearing failure, free of charge. It's more expensive by volume but about the same by use as other oils. The motors run much better with the leaner mixture and plugs foul much less. Here is the web site: http://www.opti2-4.com/ . I have no connection with any company making or selling this stuff. It just works very well. ERS |

The Golden Eagle engine kit for bicycles is pretty decent. Getting the belt drive gear on the engine to line up correctly with the drive ring you snap on your rear tire is a trial and error process though. The mounting bolts for the strap between the mounting frame and rear of the bicycle should be loctited. Vibration fatigue and broke my first strap, but I had a sharp bend in it from the start I never corrected. Top speed is around 30, milage seems to be around 200 miles per gallon. I've been able to start the Redmax engine at 6 degrees- a cool but fun ride..

This kit is belt drive? Do you have a link to the sales site? Cost?

vaguely proposed a theory .......and in reply I say!: remove ns from my header address to reply via email " installed this kit on a Schwinn Stingray. With the 50 tooth sprocket the top speed is aprox. 35mph. The mileage is about 70 mpg. Upgrading the seat to a Bell definitely improves the experience- no suspension. The plastic tensioner,the cables-gas and clutch are of low utility and should be replaced. Torque and power are a feature of this motor as is vibration. Parts not loc-tited will eject, the spark plug connection disintigrates, and the exhaust must be fabricated as just bolting on the supplied system has issues with ground clearance and an ejection problem. As a package it is addictive to operate, and the public reaction has been great." "This kit that you see on e-bay is really quite CHEAP and I don`t mean price wise. It`s made in China so what do you expect? you get what you pay for. When I got my kit I literally had to rebuild or replace everything, clutch cabel, carb, broken ignition wire etc. The motor ran for about two mile before it seized up on me and yes I had the proper oil to gas mixture. I think a person is better off getting a tecumseh or honda engine which can be easily serviced. Unless you are a mechanic, it`s hard to find somebody to service these skyhawk motors plus parts have to be ordered. Personal pet peeve is that everything is METRIC" Oh....what about those reviews?

Loc-tite is a given on every screw on every motorcycle. Yes, ground clearance on a Stingray is a given, and cables are a standard, high-maintenance part, as usual. On the positive side, he says the thing is addictive, torquey, and powerful, with public reaction great. This was the one valid review, IMHO.

I discounted it due to the 100% whine factor (there were NO positive points), misspellings, and his metric statement. Anyone with a problem about metrical whosawhatsits doesn't belong in this era. (As a recovering mechanic in the USA, with 2 sets of tools, I should know. I lived through it 30 years ago.) SOLUTIONS: As to the availability of parts, at this price, one could buy 2 kits (2/3 the price of the next offering) and keep one for spares until parts become more readily available. OR buy 10 kits. Build one, keep one, and sell 8 in pieces as spare parts for a 3x markup. OR buy an extra kit, cast or machine replacement parts of much higher quality and sell at a premium. -- total metal content g -- People will occasionally stumble over the truth, but most of the time they'll pick themselves up and carry on. --anon |

In addition to the other comments, I wonder about the sprocket sizes.
The rear sprocket is small enough that I doubt this could be direct-drive off the crankshaft, yet there is no mention of a transmission. I wonder if it just has a simple on-board gear reduction?
