Exact MT gap or coil dimensions needed

[terra 5,000+ posts]

trying to get a recone from atomic for my MT motor. They arent sure what coil will fit it though so I need to find the specs on what will fit. I emailed RE and Fi but dont expect much back. If anyone knows this info could they post it? or anyone with a MT coil laying around? measure possibly?

if anyone has info that would be helpful please let me know.

the depth/width of the gap in the MT motor would also work. Let me know so I can go ahead with my Atomic MT lol..

post on the SSA website. you're much more likely to get a response that way, than through email from my personal experience

ive posted there quite a few times and havent got shit back...

ill try anyways but that site seems kinda hit or miss. anyways, if anyone has a coil and some dial calipers and would measure..i could really use that info. thanks

i just measured one of my MT coils laying around and i got 3 and 1/8th inches diameter and 10 and 1/8th circumference.... give or take a 1/16th or so....

this was from a dual .7 18in MT fyi...

is there a big diff between coils of different imp. size?

i know there is a difference but i believe it's in the length of the coil and not the diameter or circumference since all MT gaps are the same...

ok great. if anyone else has different imp. coils they could measure it would be great to collect this info. im measuring the gap in a couple minutes..that should help

for forum reference..the measurements as best i can tell of the MT gap are..

Inner Diameter-2.955 in.

Outer Diameter-3.335 in.

Inner depth-4.360 in.

Outer Depth-3.905 in.

also, the Atomic APX recone does fit the MT gap.
