ned Posted April 22, 2009 Report Share Posted April 22, 2009 Just purchased a HJR mx ported 4mill cylinder off a member and am now wondering what else I need to complete the setup? Obviously a 4mill crank is needed but what about spacers or special domes? Also, what exhaust would be best for this setup with 33mm pwks? I ride pretty much every terrain from dunes to mx. Thanks heaps Quote Link to comment Share on other sites More sharing options...
kodie Posted April 22, 2009 Report Share Posted April 22, 2009 get some cut domes from hjr the spacer plate isn't as reliable. and you will need 795 pistons. Quote Link to comment Share on other sites More sharing options...
MarineNYC Posted April 22, 2009 Report Share Posted April 22, 2009 Make that motor shine with some 33 or 35 pwk carbs. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted April 23, 2009 Report Share Posted April 23, 2009 If it is mx ported I would probably run some t5's or DMC's, If it was a dune port then I would run CPI's drag port Shearer's would be your best bet. Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted April 23, 2009 Report Share Posted April 23, 2009 Not to be a douche but shoot HJR a pm or call him up and see what he recommends. I just built a 4mil bike and i asked my builder for all that stuff. I just got some 30oko's. Perfect for my set up. Bigger carbs with my set up will take away power where i dont want it to. I was told many time by others to go with a much bigger carb. That's just an example that the builder should know what's best for his work.
