Current pick for Best Open Primary?

[zenBD]

Happy thanksgiving guys...

I'm thinking of going with an open primary.

What do you guys think is the best option these days?

Pros and cons of your system?

I'm looking for something with a solid clutch that will handle a 124" if I go that route in the future. Something not prone to slippage.

Also something nice and clean that doesn't show any rust.

Any thoughts? Thanks!

I like my Baker open beltdrive. So far no issues. Don't know about the 124" and the clutchpack that came with it. It is an easy install with very clear instructions.

That's a nice looking set up

I believe Baker is pretty much the only option available today?

Is that right? I thought there also were Rivera and Karata at least. Not so?

Damn... that baker aint cheap. It is the best looking though

I am guessing you cant beat a Baker but just too many Dollars. I've been looking at the Rivera Brute Extreme 4 and it looks like a nice bit of kit and a lot less Dollars, I have seen a few guys on here with them and I've seen no issues with them yet.

Does that fit an 08 k9? Probably not... right side drive

We had the karata belt drive on our ridgeback with 117" and had nothing but problems without the external bearing support they offer, it destroyed the clutch pack & basket after only a few thousand miles without it, So plan on investing an extra $1000 if you go the karata route. This is what will happen if you don't.

I have had mine on (karata 4") since 2013 not a shit ton of miles but never had an issue.

Back in the day. Installed in 09 no problems to date.

I have a Karata 4", installed it back in 2010, never had an issue. See attachment

 

[Dusty.B]

has anyone ran the karata without that bearing supoort and just the cone shaped caps? We put 15k on it with the support and never had an issue whatsoever. Nice primaries everyone!

Wrong side!!!

Here ya go.

 

[zenBD]

Any of you Karata people has slippage issues?

 

[liferider]

Use the lock up clutch! The harder you romp on it the harder it grabs! This is the clutch 99.9% of top fuel bikes run! There is NO slippage!!!!!

 

[zenBD]

Call me stupid, Jonathan, but I'm not seeing these for BD RSD applications on their site. I did put an email in to them, though... have not heard back yet.

When I looked and studied open primaries & clutches. I had the same questions. Everyone said use the Karata and the Baker. When I started looking hard into the big HP bikes I found a page on Harley drag bikes. Even the Nitro class 99.9% run BDL drives with lock up clutches. This told me 2 things. #1 they make a quality product, #2 this product has no problem handling HP! Like others have said. The bearings break, ect. ect. If the BDL can handle 400-600HP it can damn sure stand up to my little 108hp V twin!
