I had a "Doctor's appointment" on Wednesday. What work didn't know was that it was a bike Doctor's appointment. I took the Mille to see Griff (Fusebox) at http://www.customrestoandrace.co.uk/ in Tamworth yesterday to have the throttle bodies balanced.
Poor old Griff was up to his neck in work and stress when I arrived, he dropped everything to work on my Mille despite me offering to re-arrange another time as I could see he was up to his eyeballs.
I asked him to check that it was fully de-restricted while he had the tank up; I've had a suspicion that the ECU was still restricted since I had a look at the loom last March.
First thing he needed to do was get the down pipe bungs out for the CO sensor take offs. Rear down pipe was fine, the front was stuck like a bastard. So side and bottom fairings off, down pipe out and then the down pipe in the vice with an oxy-acetylene torch on the bung. Man that thing put up a fight! Finally he gets it off and puts the pipe back on.
He hooked up the vacuum gauges and CO sensors and then had a look at the restriction. Air box restricter out? Check (I'd checked myself already). Exhaust washer out? Check. ECU wire snipped? Nope. **** me it was still running the restricted map! *Snip* Yay!
Then he put the diagnostics plugs in the loom together and the dash shows that the throttle position sensor is out, the ECU thinks the throttle's never closed. Someone has attempted to get around the issue by winding the throttle body screws almost all the way out to compensate. Griff resets the sensor to 0 and winds the screws back in.
Then he fires up the engine. The throttle bodies are waaaaaaay out. I knew they were out but not how far. Much ECU twiddling later and the Mille's balanced and purring. Very different noise to that it was making on the way there.
At this point I thought he'd throw the fairing back on but nope. First he topped up my oil and then he adjusted all unnecessary play out of the throttle cable (why it had never occurred to me do this I have no idea, I guess I'm just used to baggy throttles). Then he put it all back together including copper greasing every fastener and bolt he'd removed and brand new down pipe bungs.
Then I took it for a test ride. Oooooh nice. Much smoother at low speeds. Trickling along at 20/30mph is much more pleasant now. Then I took it out on some open roads. Yeehaa! More power everywhere (and I thought it was fast before it was de-restricted!), smoother delivery coming in quicker thanks to the taut throttle. I suddenly feel like I need a steering damper - it's going light at the front all the time when I'm blatting!
So cheers Griff :thumbup and if anyone needs their Milles working on I can thoroughly recommend. :thumbup
