Rev limit?

[Backfire]

my trike revs pretyt high sometimes, so i went to look at a tachometer for one so I could tune the idle, and I thought, does anyone know how high the ytm 200 can rev? it's 4 stroke, if that helps, it just sounds like it's really going sometimes, and I wanted to know the redline. Thanks

air leak somewhere???

i think it's cause it had a clogged jet and it kept dying so i turned up the idle. I definitley hope so
