I recently got my warrior I picked up running after it sat for a while, run pretty good for a couple weeks and now I’m having what come across to me as fuel issues. It starts up fine, idles great for a couple minutes and will get a hard idle and eventually choke itself out (sometimes with a little puff of black smoke, sometimes not) I’ve already changed injectors, fuel pump, I purged the lines and tried running with 93 octane and sea foam to clean everything out some due to the bike having sat outside untouched for a few years before I bought it. I believe I may have a sticking FPR or one going out. Seeing as that the part is discontinued what do you guys suggest for replacement with a different bikes or maybe a universal that someone has had some luck with or possibly a known way to fix or clean it out? Thanks in advance for all the help.
