GREENGOATCHOKER Posted September 18, 2009 Report Share Posted September 18, 2009 i'm ordering a special straight cut primary . now this may be useful especial to those with special rgv rear ends or large capacity engines . i've used a couple of programmes to confirm final speed v revs . with a 17" tyre this equates to 135mph at 10500 rpm . standard primary would be 124mph at the same revs (based on 17/40 final drive) with the rgv rear end there can come some rear sproket size issues start going too small and swing arm pivot can be a problem . waffle waffle waffle does anyone want a set they are £300 approx may be some postage . anyone looking will know the advantages http://www.gearingcommander.com/ will also fit 4lo and banshee engines Link to comment Share on other sites More sharing options...
