doh! facepalm...
personally I think any rack mount looks hokey but I guess it's practical. it could be set in lower, painted or stuff to disguise it lol
I blew a rod on a 69 Olds 350 Cutlass, did a block long burnout @7000rpm. I heard whackety whackwhackwak then it seized up. moral of the story is even solid 4 strokes don't like high revs unless they are really setup for it.
tops @ 9500? I wouldn't take it past 6500 but that's just me
