Open primary is dry, there for removing alot of friction, and increasing power slightly. Plus? there sweet sounding.... :)

The Baker belt drive is great, not very noisy as in sounding like you have a super charger on your motor. It is easy to install, looks good and it is made specifically for BDM. It is pricey, but well worth it. I had mine chrome plated, to make the cleaning easier and in doing so my warranty was voided. All I had chromed was the outer parts, I will get the motor plate done next time I take it apart.









There are others out there that look cool, others on here have Karata Open Primaries that look and sound good. I decided to go with this one. That is just me.

I really like the look of the Baker. I may have to go with it. Do you get any whine at all???

aldog, i can answer cause i got one.... the answer is nope, very little or none at all. i just called baker and talked to them about that because i like the whine. they told me if i wanted whine, go buy a junk primary. they said it has to do with the machining. i went with theirs because they give you a 5 yr warranty.

I don't know if that answer from Baker would be correct :down: I got a Karata and it whines, and Karata has been around alot longer than Baker in the belt drive scene, so junk primary :confused:..I once asked Jim from Karata if the whine sound was from my outboard bearing support goin bad, he said it was the belt and pulley making it, I noticed the BDL belt drive on my friends bike and the pulley has wider teeth than my Karata, might be one clue to the whine sound, also my belt was alot tighter/taut than his BDL....maybe Jim can explain it better, or just give him a call :2thumbs:

The whine is from the toothed belt engaging the pulley.

As the teeth displace the air in the pulley it creates whine.

Baker uses a different belt and pulley design. With this they have tuned/eliminated the sound.

Question: The unit that I am looking at is for a 0 degree off set(300 tire).Does anybody know what I have to do to make it work on a 250 tire 1/2 in. off set?

Call Baker....they are real easy to talk with and very helpful.

Thought I would chime in - I'm a big fan of Karata (have 2 sets) and would recommend it. Couple of advantages,

Choice of Belt Size
One piece back plate
Choice of Outer Bearing Support plate
For the newer models the starter is hidden/streamlined
Made here in America
Competitvely priced - all told around 3K

You get access to Jim, who is a wealth of knowledge. Good luck. yup - give him a call and take the plunge

Well said. I was just about to say the same thing. It has nothing to do with quality. I've been around blown motors all my life as my dad ran top fuel funny cars, alcohol funny cars and we have built blown street cars and they all whine. It was harder to hear on the FCs though :D

I agree, whining is no sign of quality. I simply wanted to know if they did whine or not. I like to hear the whine so if Baker doesn't, I know Karata does and I'll go with Karata. :2thumbs:

i agree with you 100%. i thought it may be a easy change to get the whine that's why i called them and that's what i was told.
