That was the first up grade i did too, mine is fitted with the auto decompression as it's 01 no e start ,works a charm.
$1000.00 for a 290 kit I would like to see some dyno charts befor jumping in on that, missed out riding one fitted with it by a day,1 was up for sale localy and couldn't get to the guy's house before he sold it
Ken put it this way my bud who weighs in at 300+lbs rides a crf 250x 2010 and it pulls him NP bone stock,but my wr is faster IMO than the uni cam and the wr turns faster/easier. Also the honda feels too soft in the suspension department every time I jump it
