how many cc's???????

[trikeman]

i just got my 250r bored 2mm from 70 mm to 72 mm so how many cc's does that make the engine now?

CCs = .7854 x bore x bore x stroke

i moved up from a 1.5 mm over bore to a 2.0mm over bore is there anything i need to do with the jets on my carb? or anything else to the engine?

I would start by ridding it first and then go from there...I would think that it would not need anything.

I've been wrong trailprotrailpro though!!!!
