Forgot to mention we are about 800 feet above sea level.

I just ordered one from Lewisport for my son's Rev 3. He said it may need some jetting changed. What do you recommend?

Honestly, I'd recommend not riding one. I loved my Rev... And then I test rode an 11 Evo.

I owned the bike before for my oldest son. We sold it, and bought it back two years later for my youngest son. Bike had sat a lot for that two years. It ran horrible when we got it. I cleaned the carb up, adjusted the floats per this thread, and she runs great. I hope your new carb runs fantastically! Thanks to all who commented here to help!

Did you ever get this sorted? My carb is off my sons Rev right now in pieces. Been doing lots of reading, and putting it back on bike tomorrow. Just curious of your results.

The clutch fix did WONDERS! The oil was just the extra little icing on the cake. Per Ray Peters instructions, my dad also used the Mobil 1 0W-40 on both his 250 evo 4t and his 300 4t with great success. I've only owned 2t. There are a lot of oil choices out there, not saying this is the only option, or even the best. It's just the answer to the problems my dad and I were both having. Just sharing my experience.

Btw, Ray Peters knows more about engines, oils, and beta's than 10 smart mechanics combined. http://www.betausa.com/content/ray-peters

I was having all the problems you were having. Ray Peters told me to switch to Mobil 1 0W-40 full synthetic (European car formula). No idea why it works, but it's like magic! Get your bike good and hot, and change the oil. Ride it for 30 minutes or longer and change it again. Also, VERY important, fill to the dot on the center of the site glass. Depending on year, that will likely be around 475ml.

Thanks guys. I bought one!

Hey guys, I've had my 2011 beta evo 250 2T for a couple years now, I'm considering upgrading to one of the 2017 world round minder evo 250 2T bikes. Several questions I'm hoping you can answer: 1. What are the differences between these bikes? 2. Any reason I shouldn't buy a world round minder bike? 3. I have done the "clutch mod", as well as added 3mm spacers to my clutch, and I really like it. Are the clutches similar? I'd hate to "upgrade" and not like it. Thanks to anyone who give input!

Looking forward to a 2T guy trying these out.

He said it is similar to a GasGas design, and won't catch at high RPM's. (which isn't a problem as I am a monkey only riding Intermediate)

Sent a message to Ben. He quickly replied. I think he has a clutch that many will want, but to rich for my blood. They are 620 British pounds, which is $900ish in US. I hope to hear reports of it as time goes. Meanwhile, I'll tinker and fine tune mine. I just swapped to 10w-40 Torco, and like it for the short ride I took. Wish I could get a hold of that fancy putoline stuff to try in the US.

Ok, I did. All I get to see is a pic and the comments. Who do I search out to get info? Web address or Facebook name. I just bought new sureflex plates, but they ate still new in the box. I'm happy to turn and be a guinea pig in these if they claim smooth engagement.
