They are all the same,EFRA 2058 made by LM.

Yup, same pipe

What is the factory carb setting for a crf 5 port

Thanks, this is a very good info, so any Nvision, Werks, is the same as the Orion one for half the price.
WWD

If i reset my needles I always go back to flush and flush as its extremely close to the stock settings.

What do you guys think about the new RS version due to come out?

Here's my story.. bought one of the deeply discounted discovery 5 port combos, took my time to break it in correctly, raced it, loved it.. till the tune started to go crazy all over the place. After some investigating, it seems the flywheel got into the front bearing, tore up the seal and let a bunch of air in. Unfortunately, dirt too... bearings are junk now. Here's the best part, in the noob move of the year, when I reassembled it to pack it away (at the track) I let the backplate get into the piston skirt! Now I can't find a piston and sleeve anywhere! I was loving this engine, just barely had a gallon on it! Does anyone have any leads on where to get a set or any others that will work?

What clutch & spring rate u guys running on crf 5 port in order to get a good bottom and moderate top speed? Tq & apreciate for any inputs.

When will the .22 Truggy engine and the CRF RS's be available?

Hard to believe there has been no action in this thread since late-November...

That's what I am wondering. I am really looking forward to these new engines.

Sorry for the dumb question, can the CRF 3Port work with P3 plugs?

yes, that's usually what I use in mine.

Ok, thank you!

I see lots of mixed suggestions for the pipe on the FT321; 2013 or 2058

Whats your latest opinion?
What are the performance differences between the 2013 and 2058 ie. is one top end or mid range , low end .. smoother or more torque ?? Thanks for the feedback
