I read on a thread that someone had the dealer raise their idle speed because it was too low at 800. Mine idles at only 600/650. Runs smooth and does not cut off. Is that too low?
The only real problem when the idle is too low is that the oil pressure is also low. Personally, I like a low idle speed, but I kicked mine up a little to prevent any possible long term effects. However, it could be argued that if the oil pressure light doesn't come on then there is sufficient oil pressure - assuming that the oil light is working correctly.
Bob Carpenter doesn't like the oil pressure at factory idle, FWIW, he recommends raising it a little. Mine flicks between 900 and 950 my digital tach reads in 50 rpm increments, he said that was fine.
I think that was me that mentioned raising the idle. At the time I was dealing with stalling issues and when I would down shift for a stop my rpm's dropped around the 500 or so range and it would kill. Raising the idle was an attempt to solve the stalling issue. I've got the idle set in the 900-950 neighborhood. Performs like no other.
When I was visiting Wayne Tripp a couple of years ago he told me that the idle should be between 1000 & 1100. I have mine set for 1050. Works for me. Most of the bikes I have had called for 900 to 1100 idle. I have always tried to set mid way . Never thought opf the oil pressure.
The original Triumph tunes had the idle set (IIRC) at around 750, or maybe a tad higher. In around 2007 the factory replaced those tunes with new ones that had the idle set around 850 (IIRC). The reason for the increase was to prevent stalling. However, the stalling problem was caused primarily by the TPS problems they had at the time - which Triumph diagnosed just after the R3 forums did.
My 2014R3R idles at 3 different rpms based on ambient temperature and engine temperature.
1050rpm when frikkin cold out and engine is cold
950rpm when warm out and engine is cold
850rpm when cold/warm out and engine is warm
After watching the oil pressur eon Gracie which was 9 psi cold when at 800 rpms I moved her to 950. to keep 20 psi on her when she was hot. Very few pieces of equipment ever die of over lubrication !!!!!!!!!
