Hey there, I’m hoping someone could help me out here. I recently bought a brand new Coleman bt200x. I put a GPS stage 1 kit on it, cut the throttle screw and did the zip tie trick for the governor. Today I went to change my valve springs out from stock to 18 lb springs. Once I thought I had them situated using a feeler gauge I put the bike back together and went to start it up and the pulley was incredibly hard to pull. I pulled a few times and then opened the head back up to adjust the valves. Once again put the bike back together and the pulley was still hard to pull. After a few pulls the string snapped on my pulley. The bike never started after opening up the head and changing the springs. Could someone please give me some insight on what I may be doing wrong? Thanks so much.
