Hill start issues with linked brakes

I agree with Maggot. More revs needed. I do this daily without issue. Sometimes I use rear, sometimes I use front...but I never have a problem stalling. Ease up more on the brake when you give it more revs. Moderation.

Are you sure your rear brake is not dragging? Sticking piston can cause dragging.

 

Put the bike on the centerstand (in neutral) and try to spin the rear wheel. If it is very hard to spin, doesn't spin, or you feel a lot of resistance you make have a sticking piston, or something else causing the resistance (worn/kinked/improperly adjusted chain maybe). In which case you have to remove your rear brake caliper to inspect. Since our bikes have "linked" brakes, you will have a piston(s) that moves when the front brake lever is depressed, and a piston(s) that moves when the rear brake is depressed. Been so long since I have checked mine, that I forget which piston moves for which lever. Many times, a sticking, dragging brakes are caused due to the tiny little fluid return hole in the master cylinder has blocked, clear that and usuall fixes the problem. You're bike is like mine....an ole girl, so when was the last time she has her brake fluid flushed and brake calipers cleaned and inspected?

Sorry to digress, but there could be many factors as to why you are stalling. Not enough revs, not enough practice (clutch hand/rear brake/throttle synchronization), leaving the brake on too long (causing the stall), fueling issue, worn clutch, alignment of the planets, you're jealously distracted because Kim Kardashian is having her second kid (without you), you're sad because Oprah ended her show.....the list goes on and on. Practice makes perfect (but don't forget to check your brakes anyways)!

 

You could try doing a proper bleed of the whole system. It would be a good idea to do just as preventive maintenance. But also if it wasn't done properly in the past, the balance of the whole system can be messed up. On a properly functioning linked brake system, 8 of 10 riders wouldn't even know they were riding on linked brakes if someone didn't tell them.

The bleed is a long process of removing calipers, standing on one foot, and saying three swear words of your choice repeatedly.
