Yes,
first I did with a V-Twin manufacturing kit.

Avoid that shit like the plague.

The oil return from the head rocker box down the barrel through an internal bore leaked oil. yes the outer casing was ..I don't know..cracked/split..what ever..it let oil out 2 fins down form the head, rear pot, back LHS,

It was a brand new kit I had, all boxed up ..but i was not original purchaser..so they washed their hands of any involvement..even though it was a manufacturing fault. It leaked from the first day.

I at first assumed I had mucked up and ballsed up the head gasket or O ring. so i stripped and rebuilt he rear cylinder.only to find it was still leaking. Only then did I notice the oil was coming from a fin or two below the head..and it was then i spotted the crack ...

Ignore that V-Twin Manufacturing shit at all cost.


All ripped off now and a Hammer 1275 kit on there now instead

i could have her rebuilt as a 1200 after the engine was totalled this late spring
i choose instead to have her back like a stock 883...
overhere authorithies and insurance companies have not a light hand about converted bike...

also in this way she keeps her value better overtime... like my previous ride did...

besides
it's not for power i bought a Sporty

this summer crossed my mind to buy again a Superbike
rode also for some time one (Kawa z900)

then now... i have my bike back and i'm quite satisfied with the way she deliver the power
i think now to keep her and change rather my car with a more powerful one
