IceAlmeida Posted December 22, 2012 Report Share Posted December 22, 2012 tyler would a 33 pwk work better for a 4mill and trail riding then the 28pwks on a 4 mil for trail riding? Quote Link to comment Share on other sites More sharing options...

I would run the 33mm over the 28mm. I see no reason to go from stock 26mm carbs to any 28mm. - HMFIC Quote Link to comment Share on other sites More sharing options...
