confused...Metra 80 help

so i recently just mounted up a new intake a tomos bit turbo header....it matches up to the mikuni perfectly. anyways so once i got this setup put together i ran my bike and it started running super rich and 4 stroking. i jetted down and still 4 stroking... i jetted down again and its still crazy 4 stroking. the intake is the only thing i have changed. is it possible this new giant intake is just dumping way too much fuel into my cylinder and perhaps just flooding the shit like crazy? should i go back to using an intake that matches the intake port instead of my carb? i mean i went from hitting low 60's and now i can't even break 50. cheers

Re: confused...Metra 80 help

You miht have had a massive air leak and compensated for it with the jet.

Re: confused...Metra 80 help

make your intake port match your intake (if u can) and re jet mopeds are finicky u have to re jet if u change any thing

Re: confused...Metra 80 help

lol! Zeke, you rock.

Re: confused...Metra 80 help

How much did you jet down?

Re: confused...Metra 80 help

yeah, i guess just do some plug chops and downjet if the plug is back. maybe you had an airleak or something before, or the intake was just too restrictive before.

you wouldn't have this problem if you used a dellorto! j/k dude, flatside ftw.

so you go from 24 and a wall on the intake port?

match that shit up.
