I am wanting to convert my 04 Blaster over to pre-mix in the not too distant future as I am much more comfortable with my own mix and it is convenient seeing as how I already do with my bikes. I and am wondering from some of ya'll more experienced quad guys if there is any kits a bit more superior than the next. I understand well what is included with them and am aware they all basically do the same thing for the same price, what I am most interested in discovering is if there are any that include a new and completely solid rubber grommet for the engine cover to replace the stock one that has holes in it for the oil lines. Any suggestions or input is welcome. Thanks guys.
