Sounds to me like you are describing "wheel hop", and my '09 750 does the same thing under light loads.......Try stiffening up the spring pre-load by turning the adjuster.Hi guys,
Because it's my first post here, I would like to salute you first and say I'm glad to be a member.
I'm writing you from far away: Europe, Romania, Bucharest
I'm a proud BruteForce 650 rider for almost 2 years now and have clocked 2200miles on it.
Everything is perfect, except this:
When riding on a steep inclined trail, powder snow 40cm (1,31 feet) deep, 4x4 Low engaged, I'm experiencing a tremor in my front wheels.
The speed is low because of the incline and lack of traction, the wheels spin but not spin continuously, they have small interruptions in spinning and have an "up-down" motion on them, like they tend to jump.
The back wheels spin continously, they are ok, but the front wheels have those interruptions in spinning, they almost stop and spin, stop and spin, stop and spin, and induce that up and down motion I was mentioning
It's important to mention that on the same incline on dry ground or on muddy ground everything is perfect.
The problem exists only on deep powder snow on high inlines. On wet snow, everything is ok.
The same thing for another 07BruteForce 650 and 07BruteForce 750i
Locking the front diff does help a little, by equalising the front wheel spin, but does not tottaly solve the matter.
Lowering the tires pressure to 2.5psi front and 3.0 psi rear also helps, you get more traction.
Can anybody tell me is what i've described is a real problem, or just a"kavi" thing ? I was thinking of damage to the front diff, but it would have to be a lot of metal loose around there. And the same problem, in the same conditions to 3 Brutes ?
Many thanks for your answers and sorry for the long post
PS. A few pictures of the wanderfull toy !
Help pls: weird behaviour in 4x4 deep snow high inclimb
