TT airbox

This may have been covered Im sure before now! So forgive me for asking. My 2002 TT has been running perfectly since I re-mapped it. The day however I rode home in a god almighty rain storm and started to run terrible towards end of ride and again the following day. Throttle all over the place, low rev idle, things like that. So initially I though must me water on the electrics, let it dry out and then all good, it will be fine. However its not fine. Start up well, but as it warming up the revs jump at lower significantly until it gets to 60 degrees and then pretty much sits at 900rpm. If I turn it off and then try to start the ignition again it doesnt fire, until that is, it goes cold again. Anyway, I take the tank off to open the airbox and Im like "where are the screws to take this thing of??" My Ninja just had 6 screws and was dead easy! How do I get the air box off so I can look at the coils and plugs and the rest of the electrics?? Answers on a postcard.......please!!!

There should be a strap holding down the airbox, if I remember right. It attaches to the throttle bodies using boots that have a spring to clamp them on. It's a push fit, not bolted on. That should get it off.

The symptoms are odd to say the least.

It's a squid thing. You wouldn't understand.

Go soothingly on the grease mud, as there lurks the skid demon.

Thanks Will. Yeah I figured it out in the end. To be fair I found a few issues under there! Damp ignition coils 2 and 3, some slightly suspect looking wiring and a worn and damaged rubber boot to the oil pressure sensor. So I'm literally going through the whole system anyway and will replace plugs as they were due anyway. I'm aware of the fuel hose issue at the female end connector (always the females!) And surprise surprise there was a very slight leak around the clip. You ever had any issues with these out as it looks bloody complicated if I have to fart about with the fuel pump! Any other upgrades you recommend whilst the bike is naked?! Cheers dude.

Those connectors are a pain, but I got along with them better than the later version on the 675. Why? Who knows!

It wouldn't surprise me much if you found corroded spark plugs as well. If the bike lives outside, which mine did, and it didn't get ridden much for a while (not a problem mine ever had), water collects in the spark plug wells and damages the coils and corrodes the spark plugs.

Make sure any openings in the airbox between the filter and throttle bodies is sealed. Make sure all the vacuum hoses between the IACV and throttle bodies are in good shape and sealed. There's a seam on the IACV that will occasionally be a problem. Make sure that's sealed. May as well replace the air filter as long as it's all apart.

There may be some other things to look at while you are in there, but I'm not thinking of them now.

Hi Will. So I pulled the plugs and 4 was fouled and wet and a bit oily. 3 was less so but still in bad condition but not wet. 2 was fine. 1 I havnt pulled yet as I can't get to it will my drive extension due to triumph putting block closer to the frame! So need to get shorter drive extension. But judging by how it's going I'll gather this should be good again. So the only think I could find was the gasket sealant on the casing seemed more work (facing the fan) on the side in front of 3 and 4 and it was oily. The other side (left side) was dry and better sealed. So....is it a case of sealing up that side or is there more to it than that? I've not gone through all the electrical lead elements and connections yet as my blood multi meter lead snapped and run out of time! Thanks. J

Gasket sealant on the casing? What did you take apart?

No, nothing yet. I'm going to take the camcover off and maybe replace the gasket for that as I think it maybe that which is perished at one side. I'm hoping it's just that anyway! Thanks for your support on this dude.

If the plug well gasket is leaking..... it will fill up the hole pretty quickly and spew oil down the side of the bike. Guess how I figured that out!
