Default Mugen Ninja JX21

i was puttin that piston and sleeve into my vspec but me being a retard didnt look on how it was supposed to go together when i pulled it out of the package

i looked at the pic on a main for Mugen Ninja JX21 and it looks like the long part of the sleeve goes towards the exhaust port right

the larger whole is the exaust port, it is also higher than the boost, the bigger port goes in the exaust side of the engine. it can really only go in one way and fit, the pin in the top of the block will match the notch on the sleeve, can't go wrong with that being lined up right.
