how hard is it to install a 14% gr on a 2000 foreman 450es? i bought one a few years ago but never got around to putting it in since i never really found good instructions for it.
When doing this do you re use your washers that are behind the clutch basket and gear14.5% on a 450 is about as easy as it can get , the primary gear and clutch basket are right out a 300 , no cutting , welding or grinding to build it , drops right in -----you need to take your right side cover off , remove both clutches and swop the parts , I would suggest a new set of clutches for the change clutch and soak them in oil prior to installing , not a fan of the heavy duty springs that come in the EBC clutch kits as it makes it harder to shift , I would use the stock springs
Absolutely spot on ?some reduction primaries have a recess where the washer fits into the recess and when the washer is in the recess it is flat with the back side of the primary gear , some don't have the recess , I think if the recess is there then you need to use the washer ----
How you get 34%?yes I did use the one washer with the 14.5 % reduction --------- I have 34.5% on my other 450 , that was a lot harder to install , I had to do a lot of grinding of the case , didn't use the washer on that one as I was told not to , but heard people that say they did ------ the two bikes make a totally different gear train sound , the one with out the washer is louder , but it is a different ratio
