The expansion chamber exhaust is from Sick Bike Parts and it's ossum!;
Sick Bike Parts
The remote airbox is my own creation of desperation, simple & cheap;
Actually - the engine is doin' really well, I've been impressed - but yeah yer right, it's easy nuff to rebuild/replace should I ever need to
I've actually had it up to the head in water while it was runnin' (missed a turn oops) and although both the exhaust and carburetor were under I just kept revvin' it till I got out. I woulda swamped it had I let it stall and/or I had the stock air filter on it.
The mag did take in some water - it wouldn't have lasted long, but I had just "nosed in" so I got out quick. I prolly outa make a better mag cover gasket
*shrug* Got home, hosed the muck offn it and dried/regreased everything - no probs with it since
My wheelset is wimpy, they're not even double walled - another thing on my infinite shopping list...
