Replacement cyl. & piston

[DRK]

Hey crassius, I'm looking to buy a replacement cylinder & piston for a motor that I bought from U-Moto a little over a year ago. You told me about U-moto, thanks by the way, looks to be a pretty good quality motor. I bought the PK Boom. I still haven't used it ( because my other bike is still goin' strong) but I would like to get a spare top end for the PK Boom. Do you know if the cylinder & piston that U-Moto has listed on their website are a DIRECT replacement?

had a customer crack his new cylinder a while back by trying to bend exhaust while attached

found this for him: "https://www.ebay.com/itm/MOTORIZED-BICYCLE-47MM-66-cc-80cc-40-MM-INTAKE-STUDS-CYLINDER-Good-Quality/283000556709?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649"

good price and even available in black

Thanks again crassius! I knew I could count on you. Looks like they have the correct piston also.

I've found them reliable and willing to answer questions by email - prices are good too : )
