Standard Air Box

[Madmax]

Stage 1 Yosh cams according to their dyno graph give three to four Hp over nine grand and lose about 1.5 hp under nine not a lot of bang for ya buk IMHO
A good tune might have given more and better results than removing the small box mod
Doesn't matter what the mod is, if it's not mapped to suit then pointless exercise all round

The dyno of the before and after showed an increase of 17rear wheel horsepower. This bike has plenty of top end and had sacrificed a fair wack down low. I should get her dynoed again and see where the changes are. Feels great down low, can't feel much change up higher apart from the fact I'm getting there faster..
