the tunnel dump can is cool idea, but do you ever wonder why cat's are the only ones that have issues bogging on the right/exhaust side??? they bog because the start injesting exhaust. there are two underhood intakes on a 2009 m1000 and one all the other Ms. exhaust gets sucked in the motor and thus it bogs... the tunnel dump won't stop the bogging, but it will loose some weight and its biggest benefit is that its quiter. something everyone can agree is a good thing!!!
now, as for the torsion kit - i hope you ran your sled in the deep stock and now you can compare it with the kit... that will really show you if the torsion kit was worth the money...
i find it funny no one tries to make a torsion kit for the Doos??? they work fine with compression spring clutches and the right calibration!?[/QUOTE]
what i find funny is that doo is still using carbs and thus are losing out on the turbo crowd, which is a very large portion of mountain riders these days
