is this the bbk you're installing? scooterelements.ecrater.com/p/18557368/taida-61mm-big-bore-kit?keywords=taida+61mmi can't wait to get my 150cc, your posts always encourage me to upgrade my ride. that kit looks awesome! although i will be skipping the crankshaft upgrade. too much work for my limited experience. Several more upgraded parts to come they are listed in my signature as proposed plans which will happen. Shipping my head off to Buford so he can work his magic on it pics to follow. you didn't order the head direct from scrappy? what head did you go with? if nothing else i definitely want one of buford's ported heads on my new ride. more pics plz and thank you.  |

Me and Buford are friends he makes my heads for my race projects i send him all the pieces, you will have to go through scrappys just make sure you tell them that you want bob in pa to make yours. I'll post many pics and maybe a vid once all the parts are in it will be a bit before I get all the parts.

As far as I know he's the only one making them at scrappys id still tell them to make certain, he makes awesome heads I'll put up pics as soon as we get mine all done. Scrappy sells the hoca big valve head too, I went from a hoca to a Buford big valve head no comparison hand ported by a professional will always beat out a machine.

Gonna order a crankshaft Thursday trying to decide which to get 2.2, 2.5, 3, 4 or 6mm. Trying to avoid the chain don't fit issue if I have to modify the cam chain tensioner and use a longer chain id rather go all out and do a 6mm and shave the bottom of the piston. Got two days to decide want to do a 3mm with stock chain but I've read many stories about the chain is to short after the spacer and gaskets. Like I said if I got to get a longer chain id make my work worthwhile and go big.

My scooter i ride to work everyday has a 3mm stroke crankshaft in it and all i did was install a spacer and that was it. Have had it now for about 3 years in my scooter with no issues at all. |

I don't mind if I have to change the chain, my concern is if the stock chain is too short I have to put my project on hold and order a chain and wait for it to come in. Don't want to spend the extra on a 92 link chain if I don't need it some cranks I see come with spacer, chain and woodruff keys which would eliminate my concern.

I will gain more torque from the stroker and more power from my head I'm having Buford fix up, I have done extensive research and this build should go without many hitches. The size of the stroker from what I have read isn't going to be that crucial say from 2.2 to 3 is only around 1.5cc or even 2.2 to 6mm is around 9cc. But if I do the 6mm it will be alot more involved to gain that 9cc of power, its doable but probably not worthwhile. |

the 6mm is amazing but it gave me a headache building. and probably more for you in the usa. The piston is required to be shaved at the top and bottom, tensior will need to be modified. grinding down at the oil pump is required really for any stroke crankshaft. Your issue is finding a machine shop that will know exactly how to shave down a piston for your scooter.
