Bump Starting
 

i Got a 93 cbr 600 recently and had the infamous issue where the engine case that holds the starter boss gear in place broke and the starter just no longer contacts the gear. i was not going to let it ruin the rest of my season so i started to bump start it whenever i wanted to ride. My issue is that it is very difficult to bump start the bike when cold. I have tried many different methods, using 2nd or 3rd gear, slamming my butt on the seat when i release the clutch, running to my terminal velocity while in neutral then slamming it in 1st, i have also tried playing with the throttle before and while releasing the clutch hoping it can pull more fuel in and no luck. i usually keep switching between these methods for 15-20 min then it will start whenever it feels like it. Once started and warmed up i can bump start it 1st try every time. I assume the issue is that when the engine is cold it has more compression so im fighting that when bump starting. Im wondering if there is any way i can be more consistent on my cold starts so im not taking up my street for half an hour going back and fourth sweating my ass of trying to bump start it. no I'm not putting a engine in it and yes i have tried to weld the case and that failed after 2 weeks.
