Default Some Tech Questions about the Banshee

Can anyone answer the following questions. I really could use the help. My brother in law is going to do the motor work on my bike and he asked to see if I could get a few R&D questions out of the way.
1.What is the stock compression Ratio? I think it is 6.5:1

2.What is the stock cc per cylinder?

3. Does the stock motor have separate domes?

4. What is the static Compression Stock?

5. What is the stock timing set at?

...If anyone could provide some support I would be very greatful.

1.What is the stock compression Ratio? I think it is 6.5:1--That sounds right.(check ymaha.com)

2.What is the stock cc per cylinder?----twin 175's

3. Does the stock motor have separate domes? I believe so but they are connected.

4. What is the static Compression Stock?

5. What is the stock timing set at?

...If anyone could provide some support I would be very greatful.

I have seen them in action. Even been on one of them. they are awesome. Mike D. is thinking about coming out of retirement to do a banshee. Those are the questions he asked me to get answered for him and then the MAd Scientist is going to go to work. Wait 'til you see what we are doing to Jake's quad... Jake wants to Flat track this year

Hey Beech, Adambomb and I are making the 1400 mile journey to Glamis for Thanksgiving. I'd like to see that 580cc run. Maybe we'll see you then...
