ebay robotechlegacy kit failed  By  millsc (Read 718 times)

its very popular lots have it, it failed early, ran strong while it lasted though

Dang that sux . Was it too lean ? Did you look at the color of the sparkplug ? Was the head gasket bad too ? Some people ride scooters at their max ability and makes then not hold up if its too far tweaked or pushed to or beyond its limits .

After having a piston crack an another 63 explode really turned me away from junk . I have had almost 40 mopeds , minibikes and street cruisers and never once had a piston or any engine damage . I was a wild teen and drove everything like I stole it . After joining SD and doing research I bought an Air Sal 50mm BBK after it was suggested and I liked the specs of it . Just by looking I could see how much better quality it was than the recycled pot metal junk . I had not heard of Air Sal before but I have read afterwards many others had kits from them and they worked good with the exception of a few soft seizes which was a jetting , leak or oil pump failure instead of the engine parts messing up . It also has an aluminum cylinder instead of iron so its lighter and cools faster . The piston and inside of the cylinder are ceramic coated which prevents some heat damage .

I put a ModCyles 47mm BBK on my 2T and was happy until the oil pump fizzled as the stock ones are not good for high speeds unlike a Mikuni oil pump which is Japanese quality . I bought because it was only where many kits are 140 to a few hundred for 2Ts . Special thanks to Teddy554 for hooking me up with a piston kit and larger idle jet as its hard to find for a 19mm TK as its an odd size but uses Mikuni VM11/22 main jets like many others .

I think its best to stick with brands like Hoca or NCY unless you can afford the Italian goodies like Polini . I have read too many horror stories about members getting junk from Ebay . I think a seller by the name of Autotech55 has a good rep as several have mentioned buying parts from him .

Regardless what all mods one does to a small engine it can only be able to go so fast without overstressing it and blowing up ETC . A BBK is great way to have more power but still nothing like a larger motorcycle with a manual wet clutch can do .

If one truly wants a small hot rod scooter then a 2T is the best option , as its less parts to put together , service or tear up , no oil changes or valves to adjust . The jetting on a 2T is more finicky , but one dialed it lots of fun times to be enjoyed

Was the oil level and color good ? I would think it would have ring dust in the oil as my TaoTao did when it blew up
