Nevermind...........I was making another attempt to be charitable. We are doing something good for the DS community next weekend at Albany and that is all I can say right now. Your new rigid would have been a worthy addition but I guess it's not meant to be.

Hopefully you decide to come up, if not.........we will do it without you.

I'm not going to get into it with you so save your typing. Either show or don't show. It isn't up for debate or negotiation.

Ron

 

What debate I only asked for your predictions of what this bike will run. I haven't decided one way or the other if I'm going to attend. How many Ds bikes will be there ? Nice 1000r by the way. Very cool bike.

 

Hope to see you there.

 

Sounds good. Would be nice to see some West coast bikes running big numbers like the boys back East.

 

Excellent![img]i/expressions/face-icon-small-smile.gif[/img]

 

So Ron if you have two bikes with 80 hp stock bore and 300 lbs. One has 50lbs reciprocrating weight and the other 30lbs. What does your math say is the difference?

 

Where would you shave 20lbs of reciprocating weight?!?! Are we talking about a small block chevy? lol[img]i/expressions/face-icon-small-smile.gif[/img]

The only recipricating weight on an ATV is internal and the motors aren't big enough for that kind of weight savings and still remaining balanced.

I know you aren't confusing reciprocating weight with rotational mass, you should have known I wouldn't either[img]i/expressions/face-icon-small-wink.gif[/img]

I can't wait to meet you, buddy[img]i/expressions/face-icon-small-happy.gif[/img] See you on Saturday![img]i/expressions/face-icon-small-smile.gif[/img]

Btw, just to humor you, less reciprocating weight to a point will result in a faster reving motor and less internal torque loss before it is measured at the crank.........assuming everything stays in good balance. It is like throwing a rock. If you pick up a 20 lb rock you will only be able to throw it a few feet. If you incrementally lighten the rock you will throw it farther each time until the rock gets to small, not enough mass. Your distance will then begin to decrease. You can throw a 1" rock farther than a 3" rock, but you can also throw a 1" rock farther than a 1/4" rock.

I have seen the same thing happen in 2-strokes where the reciprocating mass is lightened too much and you begin to lose max rpm and rev acceleration...........often times due in part to increased vibration as well.


Here is a question for you[img]i/expressions/face-icon-small-wink.gif[/img]

If you increase your bore from 100mm OEM to 105.5mm...........compared to stock would this be a long rod motor or a short rod motor and what effects would that have on rev acceleration and also, which part of the torque curve does this relative rod length ratio most dramatically effect?[img]i/expressions/face-icon-small-smile.gif[/img]

Choose, feel free to jump in on this to if you know the answer[img]i/expressions/face-icon-small-smile.gif[/img]

This is fun! I like an educational pop quiz[img]i/expressions/face-icon-small-happy.gif[/img]...........I hope you don't mind me "reciprocating" by offering a quiz of my own.[img]i/expressions/face-icon-small-wink.gif[/img]

 

You are saying increasing bore changes the rod to stroke ratio. I would love for you to explain that to me. Actually call Cape him and I have already had this discussion.

 

I made an attempt at your question. I would like to hear your thoughts on mine[img]i/expressions/face-icon-small-wink.gif[/img] The reason i ask it has to do with the same goal you are driving at with reducing reciprocating weight. We are here to teach those who know less and learn from those who know more.

It is a worthy discussion that will interest a number of people. If you have already had this discussion and you know something about it, where is the harm in discussing it?

I gave a huge hint already.[img]i/expressions/face-icon-small-wink.gif[/img]
