So folks keep telling me that the 670 RAVE motor is finicky and hard to get more power out of? Is this true? If not... what is commonly done to get some big ponies out of a 670? Thanks

not ture at all, the 670 is rotax's best engine combination, it responds very well to modifications. there is alot you can do to it, with time and money, for example, twin pipes can add around 8-10HP, you can get machine head inserts, big bore kit, bore carbs, clutch kit,UFO's, carb tuning, gearing, etc

dont forget monster stickers.. works with many makes and models, and gives youan extra 10 hp per sticker.

Just curious, if youre looking for more power, then why did you sell your twin pipes in another thread?
