Have you nipped up the intake boots? They can come loose.
If that's the right pot I'd say yes.Pete
Pete, is there anything that could be stopping the RH TB from closing properly? I just can't get my head around why they're balanced at high speed but the LH side needs so much extra air at idle.Larry, if you have it balanced at 4,000 with the bleed screws closed, is it also in balance at say 2,000?
I'll look into that John because I'm tending to that as well, but my thought is that the actual throttle adjustment might be the problem. Do I have too much tension on either or both cables?So I've slackened both of them off big time and it does make a difference to the idle balance. But before I go down that path, how do I adjust the cables properly. What's the procedure because with two cables it's obviously a bit more than just tensioning the traditional one cable against a return spring. Thoughts.?
I reckon some clown has buggered with your TB's. I sent my spare set to Belfast Dave but I've got another, hopefully unmollested, pair on the way from the US. If you have time to drop up we can try them.Pete
There is a right hand 'sacred screw'. It's not easy to get at, but I have been vexed by a 1200 Sport that had had the secret sacred screw adjusted.
I got some Quick Start stuff. When the bike was hot, 120c, it seemed to make a difference spraying it AT the spring hanging under the RH Throttle Body, but going back now from ambient to 65c it doesn't seem to make any difference.
I had a look at the "secret sacred screw" It would explain a lot if that had been messed with, but it's REALLY hard to access. Seems unlikely that someone just wanting to "adjust the idle" would choose to play with that screw, but you never know. Alternately, I wonder if someone adjusted the linkage rod. That has paint on it too and could be checked (as could the secret sacred screw).I dunno, I just think it "must" be something mechanical like that.
Well if Larry's RH sacred screw has been fiddled with, he's buggered. If it's a case of over-tight throttle cables, he might get this sorted.
And did you try it with the last map I sent?
Don't be too concerned about the lambda's. If you're going to be running an open loop map, the lambda has no affect. That is why you can't adjust the CO trim with stock map. When lambda is active, CO trim is not, and vice versa.
Don't think there is an relevance to this, but one thing I did notice going from a custom map to a stock map is it will hold the CO value in the stock map to what you had it on the custom. Guzzidiag will display the CO value of the custom map, even though the stock map is loaded. If the ECU disregards that then all good, if it does not, then maybe it can cause some confusion.When I have ventured back to the stock map, I always set my CO back to zero first, and then load the stock map back on. That is the only way for Guzzidiag to display 0 on the stock map.Again, may be irrelevant, but just an observation.
Well to be precise, there is no CO value in a map, it is stored in the eeprom memory in the ecu. So if you worry, also download the eeprom, and save that with stock map. When you ever want to return 100% stock, upload map and eprom back. The eeprom hold all more changing things like errors, tps reset value, selflearning, and CO.
