i have a very silly question and i feel like an idiot for askin this but on a wiseco piston , the arrow on top goes towards the intake or the exhaust port

[Mr. Richard]

good question!!! the easiest way is to put the ring pins to the intake side!!! thats the little pins in the ring grooves that keep the rings from spinning,,,,,,,,,

well the reason im askin this (ive already got the engine together) when i built the top end i didnt have a manual jus didnt it from scratch well the clymer manual mentioned the factory piston was mark with IN on the top and it was supposed to go towards the intake and i was wondering if it was the same on a wiseco,the dealer told me arrow goes towards the exhaust but he also told me to mix the fuel 50to 1 now that i look back maybe hes jus tryin to sell parts

[Mr. Richard]

i mix 32:1 never go to 50 ,,, 50 scares me!!! topends are to spendy to run 50!!!
