nearly a really bad day

ok asyou all prob know by i've had my fair share of problems with this 04 factory
well i have more
went for a nice run with the missus on back today - no problems, don't give it the berries as she doesn't like it, but still made 107mph nice nad gradual like.

then decided to go and blow out some cobwebs, had 2 moments, the third was definately not in my "recovering from accident" head, bike slid to the side on a right hander. pulled over to look at rear tyre, went to set off
NOWT
can hear the starter mtoar ticking, but electrics cut out, and nothing. rev limiter has been reset indicating battery removal or loss of power or short

waved down 2 fine lads on IL4's and they gave me a bump start, got home

still wont start, new battery put in 3 days ago showing 11.7v How is that possible after a long run (2hrs) and then on a blast

so start stripping her down to
A find oil that must be going on rear tyre
B try to fix starting problems i've had for a while

Remove air filter housing - full of oil, obviously i've put too much in! whats the clean out procedure anybody please?

Any suggestions on starting issues? tried new battery, all connectors are secure, relays not burnt out, starter is clicking, clutch is making a ****** noise battery keeps being drained, running battery voltage is 13.5v

now another thing, i don't oil my chain, i clean it every other day with wd40 and remove excess fluid, so why does y chain have wet shiny oil on it at the end of a ride?

i really need to find these answers and fix them with as little cost as possible or she's going up for sale

does anyone know how to clean a tyre of what could be soaked inoil splats, causing loss of adhesion.

want to say thanks to the 2 lads who stopped and helped, t spoonz for sending me the clutch sc and to all you guys on here who are going to help with this, cos if this can't be sorted then i'm off back to the dark side of IL4

so in this situation
what would your approach be spoonz?

the purpose is i don't like chain lube, its been proven that the centrifugal forces throw off more than 90% of chain lube in the first 10mins, i've run bikes for nearly 20yrs and done the same wi no adverse affect.
i require
the instructions for clearing out air filter etc afer too much oil in
clean rear wheel
improve ngine starting characteristics
stop me spending money

thanks everyone
busy day for me today then

any final ideas on cleaning rear tyre as well, or replace????

ok stripped the bike after a test start this morning, noisy but she started

then went on to clean airbox out etc and drop a little oil out.
during my fettling, i have noticed that this bike must of had some sort of alarm on it as the 2 wires that feed the connector to the soleniod under pillion seat were chopped and tied together and wrapped in insulation tape.

i chopped it off and used a proper electrical connector, tested and started again, noisy but fired up.

assembled bike ready for 20min run to check oil level.
bike wont start exact same as yesterday, removed battery and put on multimeter 12.5v

what the F**K is going on????????

gonna remove ride side fairing to check relay in a minute, after that its down to garage for him to charge me a fortune

is there a test of the solenoid i can do?

it seems as though somet is pulling the power off the battery during fire up

i think i've sorted it
the solenoid (starter relay) has nuts to hold the relay wires and copper nuts under them. these were loose, also i put the old battery back on and no clunking or noise or noting, just fires up.
i dropped about a pint of oil out and now after a 20 min run at national speed limit, when checked the level is about 10mm of max.
so there was defo too much oil in

checked rear tyre and all seems ok now, no splats of oil on wheel or underseat.

will keep an eye on it this week, if all ok then change the clutch sc next weekend as that is definately leaking

thanks everyone for the advice again
