i,d say go get a fmf fatty
mine has one ,also worked cylinder .larger squish by 2 x 1 mm headgaskets
the real bite is a bit flattened out ,so you can reach work kinda safe way
mine does run 1:40 and i carry a measured quantity in a small container,
this way you always can fuel up
i do my rides this way ,start it up then easy take off.
after a min or less i can start cleanin the pipe.
then when its clean i do not rev the heck outta it .
i ride ease for another couple o miles ,then WOT
