three rollers is the only way to really keep it balanced without some serious work.
I am probally going to but them back in later once I make a bigger change

 

And why isn't 4 rollers balanced? 2-space-2-space.
All my motors run 3 or 4 rollers.
Like I stated. Never a balance issue even when I ran with 5 rollers.

 

This clutch has 2 side by side then a big space then 2 then big space then 2.
Not six rollers evenly spaced like you are think of.

 

Looking at the pic provided, I see what you mean. [img]i/expressions/face-icon-small-smile.gif[/img] I have been into clutchs like this.
From my expieriences with different weights and numbers of rollers thru the years, I don't think there would be any balance problems. To run 3, 4, or 5 rollers at least long enough to find out what weight is needed/close shouldn't hurt anything IMO.

Why do you say that 3 rollers are too light - other than great acceleration out of the hole (which is why I did it) why is it not so good then ?

 

3 rollers are fine... i have no idea what everyone is talking about it pulls nice and you can't really judge it until you change out the cdi box Top end power is the same low end it's a monster

 

We have been running 3 rollers for a week now with no problems. If it is really a concern I know you can buy the roller kits by weight. The bottom end is much improved. Thank you for the suggestion.

 

Got tired of waiting on th esprockets to come so I machined out my own rear sprocket. Took a #40 roller chain sprocket with 48 teeth (stock 37) machined out the center and drilled some new hole. That should make a big difference just have to wait to go riding again now.

 

Top speed isnt that great really so I wouldnt have thought gearing it even further down would be a good idea.
Acceleration will be very rapid but surely you'll reach top speed in about 20ft with that gearing ?

I notice too that CT Racing offers the CDI for $194 approx but it doesnt show up on Dyna's own website - perhaps they were specially made for them and thats why they're so dear ?
