Looks good Dave. A bloke at work had one back in the day. Bit of a beast.

I have ridden a TT350 that belongs to Ekpent...fabulous amounts of low end grunt...serious field plowing, stump pulling, drag your whole house down the street type grunt.
If it works good, it looks good...

A lot of bikes have a battery to satisfy legal requirements. So some places they need to power light with engine off. Saves from getting rear ended at a light if your engine stalls.

thanks Frank,australia had different "adr" (AUSTRALIAN DESIGN RULES) than the states,i dont think these could be ridden on hi ways over there?this has a factory compliance plate on it,dated 12/87,so any rules up to then only have to be observed,for instance say a 2005 bike the rules would be tougher,like smog control and noise,tyre type etc?i wanna quieten this thing down,its got a white brother muffler,goona drill the rivetts and see if i can repack it?its got a #$%*en piston as an end cap?i havent run it with this out itll bust ya ear drums?

the speedo mount was all funky,the trip meter knob rubbed on the bar mount bolt,the cross brace bracket also was fouling on the master cylinder,the master clamp wasnt squared down on the bars!i just used the air die grinder on the cross brace clamp and all good,a lotta guys wouldve just bought this bike and run it as is saying #$%* like "IT #$%*EN FLIES"etc,i like to get the attention to detail down first,after all this is an enduro bike and should be trouble free with minimal maintenance,im guessing this is the first good look at for a coupla decades?

fully cleaned the airbox once removed from the bike,the air filter foam had disintergrated all over the insides with residual filter oil im guessing,what a mess,it might run better again once i install the new motorex foam filter,like i said a lotta guys would just run this bike with no looking or checking #$%*,its #$%*ing 33 years old!and with the decent suspension these got still quite a capable bike amoung the new ones.

Ha ha, I love the "Easter Resurrection" reference Dave, very good. It looks like a previous owner wasn't real big on attention to detail, so it's good that you are. I'm guessing that half the problem with your switchgear/ergonomics is because someone's installed those fancy pink handlebars, which are wider than stock? I'm glad you replaced the foam filter, I've seen so many bikes/mowers/chainsaws that have been run after sitting for many years, sucking petrified foam filter material into the carbs, and blocking jets etc. Good job. ;D 
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

+1 on old foam filters turning into crumbling dust.Seen those before ! Enjoy your big thumper Dave. I defied the governors order yesterday and picked up a Pandemic Project baby thumper, a 2002 Honda xr200 for 400 bucks from an older gent. Ran when parked quite awhile ago !! Never heard that before  ;D Tore it down already and the carb is really dirty. Hopefully a quick easy overhaul.  Eric
