@ Roach, mine surges a little when I go from N-1st, I seen you had mentioned this so I have to ask, I'm thinking that the clutch needs to be adjusted, or is it something else that I should be looking at? I'm new to the cruiser and I'm coming off a duel sport and have raced quads and don't remember any of those doing that.
It's likely just the resistance between the opened clutch plates and the oil between them. It probably goes away once the engine is warm?
The term "a little" is a somewhat vague I guess.
You have to realize what is going on when you make that shift from N to 1st. You have an engine running that is creating a lot of torque, and with the clutch released and in neutral, the plates are pressed together and the gears in the transmission are all spinning together, just not engaged with the output shaft.
When you pull the clutch, you are making room for the clutch plates to separate from one another. But you are not pulling them apart.
When you shift from N to 1st, the output shaft is instantly connected to the spinning gears and the clutch plates are forced to break loose from one another.
When the oil is cold and thick (more viscous), some of the power from the engine will still be transmitted between the plates, and to the rear tire. But normally the resistance of the bike's tires and rider's feet are enough to overcome this, even when the oil is really cold.
It's working like a fluid coupling, sort of like the torque converter on an automatic transmission vehicle. The car will want to pull ahead, but the brakes can overcome this force easily.
Once the oil warms up a bit, this force diminishes almost entirely.
If it wants to pull ahead with the clutch pulled and no brake, then you'll want to track down the issue.
