aermacchi racer, lovely.

number eight.

yeah, the label is racing but the photo is a gratuitous tattoo shot, what's the relevance?, well, it's ok drilling, milling and lightening components on the bike to get an increase in performance but what about the weight of the rider?, how many times have you heard some bloke giving it the big one about their light weight exhaust, wheels, fasteners ,pazzo levers, heel plates etc and then looked at them in their leathers that they had to kill a whole herd of cattle to make? get some weight off fatty, your bike will be faster and you will be fitter which means you can ride faster, i've been on the scales today, i'm weighing in at 79.1 kilo's [or 12 stone and 6 pounds in old money], my bmi or body mass index is 21.4 %, when i was training for karate competitions i was 12 stone with a bmi of 17% which means i have to get my finger out and get some serious training done after the holidays to get about 6 pounds off, i know i have to keep some stored fat for physiological function but i've got to knock the alcohol and pringles on the head.

remember the two brembo's i picked up a couple of weeks ago?, well, here they are after a bit of treatment, the gold anodising was shot on both calipers, when i cleaned them up they were both showing signs of corrosion where water and salt had worn away the anodising, to get them stripped profesionally is an expensive option so i turned to the time-honoured method of using a well-known household product to strip the shitty gold finish off them, yeah, it's true, mr muscle oven cleaner will strip it off, get some newspaper on your bench, a pair of rubber gloves and an old toothbrush, liberally spray the mr muscle onto the parts and leave for twenty minutes, give it another spray and get to work with the toothbrush, it isn't easy but if you have the patience you can get good results, the bare aluminium goes black due to the chemical in the cleaner, get your drill out and stick a copper wire brush in the chuck and off comes the black residue, a bit of wet and dry, [just on the raised brembo casting] and a quick rub with scotchbrite and they look like new, the pads in the four-pot, four-pad front caliper just needed a quick glaze busting with 320 grit wet and dry to go again but the cagiva pads in the rear caliper are shagged so need replacing, dug a stainless bleed nipple out of my stock and change the caliper body bolts for stainless and they will look the business.

top-yoke.

top yokes had a bit more work, slots milled in to lighten it off and spindle nut counterbored to recess it flush with the top of the yoke, needs drilling and wire-cutting so it will clamp onto the fork-legs and spindle and perhaps a counterbore under the fasteners so the head of the bolts will sit flush, not sure whether to use two six millimetre or one eight millimetre socket head, oh yeah, they need tapping out too.

offered the aprilia mudguard up to the forks and realised that we don't need the rear mountings so off they come.
