I recently purchased a 1994 honda 300ex and it needs the top end rebuilt. Should I go stock or a big bore kit. I definitely would like more power but don't want to do a lot other mods to make the big bore kit work properly-any recomendations?

 

you can do stock and they should also do a performance one thats just a higher compresson piston but it cost twice as much as the stock but it will give more poer and torque youd be happy the big bore might be over kill and alot more work

 

With the big bore on a 300 ex would be some what pointless. Also most importantly you would loose engine reliability. I would just bore/hone it over then get yourself a wiseco piston kit.

 

Yea , imo its not worth it.
