I'm not a genious on big bore kits...I know they bore out your engine.....but I plan on boring my scrammy out to a 600 later on this year.....will I have to do anything else if I get this bore kit...like,,,will I need a higher mm carb? higher piston? cam? rejet? anything of that sort..or will it be once I get the big bore in it then it will be ready to fly??

You might want to look into a +1 swingarm to help in keeping the front end down a lil.

 

you should get it ported at the same time, and also get a bigger carb and pipe so it will flow more gas/air! The piston/rings should come with the kit if its a good one. I would also get a higher lift or duration cam for it.
