I have a 2017 Yamaha ttr 230. I haven’t started it in about a year. I drained it, cleaned air filter, cleaned carb, and charged battery but it still won’t start. My brother pushed me and I started it in 2nd gear but it’s super clunky. RPMs shoot up on its own random pops and clanks. If I break and stop the bike will turn off. Don’t know what it could be
