Hello all. I purchased a Mito 7 Rally recenlty at a killer price (under $230). I have it bolted in a Hyper 7 with a 41019 manifold and 9886 pipe. I have never owned an Onroad engine as Im a offroad guy. The Idle sounds high but the clutch does not engage and the Idle does drop off lower after 10 secs or so. I have leaned the low speed and it still drops off. I have a good tune but it sounds super lean on the high but there is good smoke and temps never higher than 220. What kind of plug should I use in this thing after the stock plug goes out medium or cold? I have 3/4 gallon on it so tried to keep it a tad rich but this thing has a high speed scream that scares me. Is it normal for it to aound like this. If I had my P5XL or Alpha 3port screaming like that it would def be damaging. One more question this thing seems to empty my 125cc fuel tank in 4 mins flat. Is this normal? What size tanks are normally on a GT car?
Any help plz.
