hi ,
thinh the carb set up is same as 650v then the choke plungers are a real pain in the ass,
Always requiring pulling out and spraying with wd40/acf stuff, usually every 6mnths more if it rains a lot.
think the rain runs down cable from choke set on bars then corodes the springs, a good spray of the spray does the stuff.
But normally you get eratic tickover when engine hot and at least wrong plug colour, sounds to me the jets were changed as when choke applied -ie fuel richer it wont start so mixture wrong or air filter blocked.
happy fiddling

give the bike a good spray with "acf" now and forget about cleaning till spring.
