so far so good


No complaints yet. Although i had to upgrade some components. Cams (stage 1 exh/int). Replace clutch plates and springs. Also added the yoshi pim-2 to help out with the fuel mapping. I wouldnt suggest just adding the big bore kit by itself.


maui, hi 96793

nice full kit, only complaint was the brass dome was slightly not flush with the head, local bike shop knocked it down in less than a minute

Big bang for your buck!


This product is a dream come true for those looking for that extra kick of power. This Big Bore Kit will boost your 250 to 290 off the bed. It's like Nitro boost on your bike.

Athena Big Bore kit


Just been out for my first ride since fitting my kit to my YZF 250 06,found the power to be a lot different from stock 06. Heaps more bottom end power and still revs all the way through to top end. I would recommend this to anyone looking at trying to get away from excessive clutch hand workout."
