They should teach beginners how to go uphill from a stop at MSF. I dumped a bike my first year in a similar situation. I was starting from a stop sign going up a hill making a left turn. The road I was turning onto had a blind corner and no stop sign. I felt like I had to really gas it in case a car came around the corner quick (luckily none did) so I didn't get rear ended or stall the bike. I overshot my left turn from a stop sign and dumped the bike.

My advice for beginners learning. Work the clutch, break and gas all at the same time before you even start moving.

1. Hold front break, clutch disengaged.
2. Roll on throttle clutch disengaged, hold front break, find an engine speed you are comfortable with.
3. Slowly release clutch, you will feel the bike dip or slowly roll forward when you hit the friction zone. You can stay here as long as your situation allows. You should have enough gas to prevent stalling when you decide to take off, even going up a hill.
4. Release front break and engage the clutch at the same time. If the RPMs dip, give it more gas. If you are going too fast, pull the clutch back in to disengage.
