sry guys, its a 03 suzuki z400, all stock except for intake, do u guys kno what shims i would need for a stock z400, this mechanic told me it might be those b.c i lost my old ones

so i had my engine out last year all apart, i just put it in and it runs great, but after 1/8 throttle it has a bog/stutter even in neutral, like when u drive too fast in reverse, i checked all my wires but still cant find the problem, any ideas would be helpful
