I blew my last piston.. i put a larger one in.. My buddy was tellin me i may have to get larger jets to have the bike run right... Kinda makes sence but i didn't know if it was a serious issue or not.. any ideas? I"m runnin a stock carb. nothing special.. Thanx for your help.
ps was tryin to give out rep points for the help yous give but cuts me off after like three people.. sorry.. will keep tryin.
 
Nah, you should be good with what you had, unless you were running lean and that is what caused you to get a new piston.
Over boreing really does not change much with the motor.
 
some times u may have to go up ones size if you bore it over a fare amount. most of the time u will not have to at all. and like stated above u need to find why i blew up in the first place so it dont happen agian to ya. put it all together do plug chops to check the color of the plug and do your heat cycles retorq gaskets to amke sure they are holding proper torq, just adjust the jetting after running and based on the color of the plug and how it runs these two thing will be tall tale sings of rich or lean jetting
