Okay so i have finaly got my quad back amd all rebuilt. Been run in and now want to change some bits. Findimg the gearing way to low, i use this for road use so goimg about 45 feels like im reving it to hard, i know there is more power there but dont like to feel like im thrashing it, so i have a 13 front sprocket and 40 rear and running at20 tires on the rear. What could i do to get better top end, when i pull away all it wants to do is lift onto the back wheels until 3rd - 4th gear. Just want more top end
