Honda H100 SJ Questions

its a Honda H100 SJ from 91 i believe

started poking the h100 tonight, in an effort to give it a bit of a going over, i've owned it for about a year and havent done much in the way of maintenance

its definately one of those situations of not knowing where to start or how much to bother spending

becoming, as ever, frustrated with the haynes manual, because it covers the whole range of h100 models, but tends to generalise between them all, neglecting to pick out specific model differences within the maintenance procedures

my basic issues are

electrical gremlins - im starting with the battery, giving it a full charge, and if it doesnt hold charge, then ive got a spare standing by, the bike electrics werent working properly when i rode it from my parents to my new place, the battery was dead, the headlight was working when the bike was running at decent revs, but the tail light and indicators were not

if it turns out to not be the battery causing this issues, where do i look next reg/rec?

air filter, ive bought a new element to cut to size, it says i need to put it in 80/90 gear oil, i've not a clue what gear oil is? where to get hold of it? or how im supposed to apply it to the filter? any advice?

i know there isnt a conventional oil filter, but i was wondering if any owners know where the any filters are that might need a clean out, i believe there is one just after the 2 stroke tank, but i was wondering if there was a filter for the gearbox oil also? if so where is it located

leaking fork seals, anyone changed the fork seals on a small capacity bike with what i imagine to be fairly simple forks, is it a job for the amateur home mechanic?

this screw

its rusted nicely to its nut, the nut is made captive by a nut shaped recess of plastic in on the other side of the airbox, im sure your familiar with the kind of thing, however when you try and undo the nut just forces its way round in the plastic recess, and there is no way to hold it in place, ive tried squeezing the airbox at this point with a pliers, but the nut still just spins with the screw

here is a photo of the main electrical black boxes on the bike, and i was wondering if people would be able to identify what the particular ones are, there are four in this pic

i left a tube off when i last took the bike apart, and now a year on i cant remember which tube goes where, basically i was hoping an owner would be able to tell me which tube is supposed to be connected to the port in the picture its just above the what is either the throttle stop screw or the pilot mix adjustment screw (not sure which is which yet)... as viewed from the right side of the bike

heres the throttle stop and pilot airscrews

Gear oil is horrible stuff, smells, I use normal engine oil in my small honda filters, but you might find gear oil specified for your forks as it is on mine.

Top of the exhaust header.

Inside the chrome mudguards, this happens on all small hondas with chrome mudguards, they rot through. If you get a new one (pattern ones aren't expensive) give it a good thick coat of paint on the inside surface.

Some rust on the wheel rims.

a bit off topic but i did one of these up that had been stood, made a tidy 300quid profit but it was a bit of a ballache, the electrics break for FUN!
