Need advice with possible fuel pump problem.
Bike is 1997 ST1100 ABS with 55k.
This weekend I rode to western NC, the tail of dragon area and rode 4 days with the Yamaha xs-11 rally, hard twisters, fast sweepers, and steep mountain roads.
The last day of the trip the bike lost power and acted like it was out of fuel, I kept it running by twisting the throttle and using the choke, but it died after ? mile. It had 210 miles on the tank and fuel gage said ? tank of fuel.
After a few minutes it restarted by using the choke, it ran rough for a mile then ran better, then died again after 5 miles and would not restart.
After getting the bike home (next day) the bike started.
Things I have done are:
1- Checked fuel cap vent and vent line-OK
2- Checked vacuum fuel shut-off valve-OK
3- Checked fuel filter-OK
4- Checked fuel pump fuel flow- 1150 ml per minute
5- Checked fuel pump amps- 1.37 amps
6- Checked fuel pump PSI- ? PSI maybe ? PSI (gage is hard to read that low) I can easily stop the flow with my finger.
Any ideas what the problem is?
