Well Well! Here is the update , after years with the same problem, ie shutting down in ambient temp of 35 deg C plus I have finally solved it! Even though the bike would crank over and start after being parked for 4 weeks at a time , the problem was the battery. New one installed and now able to rid...

Fuel pressure gauge is the next mod, could also be helpful in the future so will install.
I am also ordering a new hall sensor ,will keep you all informed if that solves the problem, hope to buy another Rockster for my other home (Ireland) so lots of parts in stock.

Well it's 38deg C out during the day and no luck with any of my efforts, still able to ride in the evenings and early mornings though. Tank hoses , clamps ,screen checked, all good. I will mention that 2 years ago I replaced my fuel pump with one I bought at Boneyard (US made)The quality seemed bett...

Thanks Mike; I was away for a few weeksand have just returned, did try switching the relays(i do have ABS) but to no avail, took me to work fine yesterday but when I left the office at 2pm it acted up again( starts fine but after 2 min of running she bogged down) Waited till late evening when temps ...

Right then, I will check the connection to the sticks.Rode her today , cool morning it was and she ran without a bother.One thing for sure though it is definately a problem related to ambient temp rather than the actual engine temp for now its midday here in Abu Dhabi and I know even after sitting f...

Thanks for all the suggestions, and to answer the ones 1. 4 plug Rockster 2. I've changed the coil sticks. 3.Checked the wireing (by the time the tank is off etc. she cools so??). Another thing that happened was it was just 28 deg but the bike was left in the direct sunlight for a hour after a short...

WTH , summer is soon approaching here in the Middle East and now that the temp get to 30deg C my bike is rough and shutting down again. Over last year or so I changed crank sensor, coils, air intake sensor,fuel pump and hoses and today the O2 sensor to no avail! She ran fine in the cool months and n...

OK ,it was the crankshaft(hall) sensor,but it now runs rough,I was told my airbox is leaking but I am going to pick it up from the dealer and sort it myself(they want to change the entire box)$$$$$$.
Will keep u posted.

OK ,now at the mercy of the dealer,hopefully it will be sorted soon.
Keep u informed.
Thanks again for all suggestions.(any bets??)

Mysterious it is,checked,swapped fuses,verified voltage as recommended at TPS,it all seems good,now thinking of fuel distributor. Any more inputs much appriciated,havent heard of problems with distributor,it seems simple but not sure of all it's duties,does it sense pressure therefore cutting out fu...

I did come across someone on the forum whose TPS failed without warning and am lookinking for sympthoms to confirm the status of mine.I have had a look at the hall sensor wireing and it seems fine,other sympthoms I have read on the forum for the hall sensors are not evident so now focus is on TPS.I'...

Today I spent some more time on it,cleaned connectors and further inspection on wireing,nothing obvious ,strong battery and tumbled.It did fire but only sustained for 3-4seconds without responding to throttle inputs. What I did notice though was the pump whined,stopped for 2 seconds then whined agai...

all lights illuminate,fuel pump whines and puts out pressure,when I changed the pump I also used proper clamps & hose.I even put a capful of fuel into the airbox and only then it would start for 2-3 sec.It is my first BMW,been workin on bikes for 30 yrs but this one has me beat.Maybe something s...

Just would not fire up, changed pump,filter,stickcoils,plugs,checked injectors for spray pattern,reset motronics .Help
