Idle gap i about .7 mm.
The engine runs great, it goes straight back to an even idle when I'm off the throttle.
Has good clean take off after 10 seconds.
MassiveMods might be onto something with the exhaust seal. There is a tiny bit of movement when I move the header side to side. There is no oil mess around this area though.
Could the exhaust leaking out where the header connects to the engine cause a lack of pressure so fuel is not being pushed for a split second?
Ok i run the Go .25 6 port with the hong nor 2027 and it has a small hesitation on bottom too so im sure its the pipe. everywhere else in the rpms its AWESOME other than that. I run that in my jammin x2 truggy and with that pipe is supposed to be good on top and mid kinda like a jp2 i will be testing another pipe this weekend and will let you know what happens with it later will g
