What did you do to your bike today?

I've got a vacuum bleeder and it works well.

The manual way works well but a little slower.

Key thing with the bleeder is to get a decent seal on the bleed nipple otherwise you get false air bubbles and can't distinguish if air is coming from the brake lines or the vacuum it self
 
Dropped/came off it Approaching a Bend as I normally do(energetically), braked and the front locked up, let off and then straight back on, locked up again. Decided I wasn't going to stop nor was I going to get around the corner, so chose a low part of the kerb leading to grass across the other side of the road(left hand bend), got onto the grass and then dropped it. Must've slid about 10/15 metres on the grass, and far far less damage than I anticipated.

Deep scratch on the fairing, pretty big crack on the fairing and a slightly bent gear lever. Gearbox still fine, no damage to indicator, mirror rear fairing or anything like that. Will add pictures this evening. Very lucky to get away with what I did; no damage to me whatsoever
 
I took back wheel out, brake calliper off, brake line supports off and end can off.

Then I cleaned the swingarm down, taking the chain adjuster out of left hand side but it is seized in on right side. I'll clean it down further tomorrow and clean up bolts and relube them.
 
Had a nice ride out to Boxhill and Newlands corner, could have been better however... the Tuono is STILL cutting out! :(

I thought it was fuel level related (happened on an emptyish tank) but it started again today with barely 60 miles done, half a tank left. It's definitely heat related, i.e. the hotter the weather and the longer the bike is running the worse the issue gets. The bubbles from the fuel pump are deffo something to do with it though. So, when I got (limped!) home, what did I do?

Drain the fuel tank and remove the filter, of course!! :D

There was still some fuel left in the tank here, hence why it's in the position it is.

Fuel pump out, and the hose that I thought was cracked/split, is in perfect condition... :(:rolleyes:


next step, check the pre-filter (teabag filter) on the fuel pump...


Ahaaaa! Properly dirty. So, if my thinking is right, the dirty filter is restricting the fuel flow to the pump, which is then overheating becuase it's not getting enough fuel, which is causing cavitation in the pump, the air is then getting shoved round the fuel system and coming back into the tank via the return line (which feeds back almost directly into the fuel pump). becuase how else would air get into the system, and cause a jaccuzi in the tank?!?! :p

A few other people have said this teabag filter is the cause of so many problems.

It's then a vicious cycle, made worse by the engine sitting directly under the tank warming the fuel up (the tank is physically warm to the touch after riding), and the hot weather also heating up the fuel. Warm fuel into a fuel pump that's overheating due to lack of fuel flow = running like **** bike!!! I nursed it home on the motorway but it felt like it was running on 1 cylinder, rough as an old dog.

I may replace the fuel pump too as if it's been overheating that can't have been doing much good to it.
 
Saturday I booked it in for two new tyres, (Pirelli Scorpion Trail II's), ready for our trip to Normandy at the beginning of May :)

Then yesterday I fitted the following: Started with a Touratech Locking GPS mount, then a Roadhawk Bullet R+ camera was fitted and hardwired it in, then last but not least fitted a new Touratech solid type headlight protector to replace the wire mesh one that I really prefer the look of but this one gives the headlight a lot more protection.
 
I took back wheel out, brake calliper off, brake line supports off and end can off.

Then I cleaned the swingarm down, taking the chain adjuster out of left hand side but it is seized in on right side. I'll clean it down further tomorrow and clean up bolts and relube them.

Got the adjuster out with some special molegrips, cleaned back wheel. Need to clean other bits down more but coming along.
 
This was done yesterday so technically a day late, although I have changed my oil and filter today. Covered up now until after Easter as we're going away.

Remapped at PCR Performance. The red lines are obviously before and you can see from the bottom graph how lean it was running through the rev range, which causes the snatchy throttle MT-09's are known for. It's much smoother now although haven't had much of a chance to give it a good run.

and it now has a lovely PCR sticker on the swingarm :)

Nice, didn't PCR managed to get 198bhp out of the new GSXR?

I fixed my headlight after having too much fun on Sunday...

They did!

I've whipped my ECU off to take to him to enable the quickshifter, ordered one last night! So looking forward to putting some miles on this when it's all done!

Cavitation can not create air from nothing, if there is air in the fuel there must be an air leak. If the fuel is getting hot enough then it will vapourise, so perhaps you have a vapour lock problem?
