the 74-75 YZ360 is reed valved and the 70-71 RT1 is a piston port engine and the intake side of the piston is different with the reed valve piston has windows and the piston port has solid skirts on the intake side. might want to watch the listings on Ebay or other more local areas. are you putting together a 74-75 YZ360 or a RT1? the 72-73 RT2 and RT3 are reed valve engines and those have the windows on the intake side of the piston. |

i think a 184 P2 is for a 1970-71 RT1M and Enduro plus the RT1B Enduro and RT1B MX of 1971 and it is .25 mm over.it is a first over piston if i have this straight. i have a 184 P5 (i think) in a 1970 RT1M.it is a 060 piston which is 1.5 mm larger than standard. Yamaha pistons only go up to 1 mm over. what bike are you building? |

if Vintagelsinore does not show back up i found some possible sources online. https://bore-tech.mycafecommerce.com/Wiseco_Pistons these are a larger over size but they are out there. http://www.ebay.com/sch/i.html?_sacat=0 ... wiseco+184 |
