it was one of the few boxes we had left, hope the filter sorts out a few fuelling issues for you, from memory my k&n leaned me all the way from low to high rpm, so expect your fuelling to richen across the rev range.
for me, the k&n was the only way to get the pilots to fuel properly, was way, way too rich before with stock filter.
my rad brackets are on and ive temporarily "fixed" the LHS rad bracket - the aly tab it attaches to has been broken and lost a long time ago so ill need to get a new one welded at some point...gotta buy a few fairing brackets and then i can drill the fairings and have it looking like the front end of a proper bike
might get the scales on it soon, i know there is a ton of weight still to be lost, 3-4kg exhaust, 2-3kg subframe, 1-2kg clock/fairing stay/front subframe bits, 1kg scooter rear brake+holder, dummy tank maybe? it still feels heavy, but i would like to weigh it to know what its currently standing at

UK ZXR400 L3 (1993) - Fully restored and on the roads, my green beast!
