Hi Guys,
I'm trying to find a hard starting problem I have with my 02 R1150RS and I want to find out what the factory spec is for the angles of the TB butterflies at all 3 positions of the High Idle lever.
I suspect mine are low...... My TPS and idle stops have NOT been interfered with.
Word is that the High Idle cables stretch and go out of adjustment. The bike is 15 years old after all..lol
Using a GS-911, I get :
High Idle Off=0.64°
High Idle Mid way= 1.59°
High Idle Max ( hold on ) = 3.19°
I have seen one mention that the mid position should be 4°.
( from 'Roger04RT' on the MOA forum, from a few years ago.... )
He then says he got best results with 3~3.5° at mid position.
I've also seem someone else had ~2° at mid travel and ~4° at full Fast idle.....
Others just say' adjust the cables to minimise slack and leave it at that.
I'd like to be able to adjust the left side to correct value ( and hope the FULL position is also correct, and then use Vac gauges to adjust the right side to the same, so I get the correct angle AND the throttle Bodies balanced....
This sort of info does not seem to appear in the specs anywhere I have seen.
I'd like to have a definitive figure to work towards instead of guessing or trial and error....
Ive done all the easy stuff....and still have stuff to check, but this *seems* to be a problem. I won't know until I *fix* it...
Can anyone help me or point me in the right direction?
Steve
