After a (long) complete top and bottom re-build on my 99 wr400/ now 426 my machinist had hooked up my acv/carb lines bypassing my hot start. I have the 1999 model without the red button and did enough research to know I have a after market zip ty bar mount system with acv valve. Question is where do the vacuum lines go (pictures would be of great help here) to properly install acv and hot start? BTW bike is running tip top and is EASY to start and have never had to use a hot start button before. However it must have been installed by the previous owner for a reason and seems like a waste not to re-install.
