Cope Where do you get off making comments about another riders rear end? You have made him all fluster.

"Hello, Im a week away from nationals and I am not fully happy with my rear end, since Ive always rode Scorpa" Mmm ..... was you boyfreind happy with your rear end when you rode another type of bike? Just ignore him and his comments, maybe another will like your rear end.

Jim Jetting is such a personal thing. With all else equal (the bike running okay in lay mans terms) what works for me may not be suitable for you. With that been said most buyers of a the Beta Evo four stroke have re-jetted and re-sprung the CV diaphragm spring. The parts all in cant be more than $30 USD. Get a hold of your dealer or call Tim at American Beta to obtain the parts. If I can help you e-mail me @ billytraynor@hotmail.com Billy

Okay.... Hers is one. Who played for Rangers for 25 years yet never kicked a ball?

Jim I would use the exact jetting/spring I have mentioned in my prior postings. Change the plug to the iridium verion. Have you tried playing about with the mapping switch! Ie position 1 soft & position 2 hard! If you check out my You Tube videos you can hear how it runs. Let me know how it goes. BillyT

Ron I have the jetting @ # 20 Pilot, 112.5 main, CV carb spring changed from a stock .027 spring wire diameter to .025. The clip is second notch down from top. I am riding at two elevations 800 ft & 6400 ft and this jetting works great for both altitudes. I have changed the plug out to an iridium plug and that has made quite a difference in how it starts and runs. Of course the Jitsi fuel screw installed and adjusted as need be for weather, humidity etc. Also very important to keep the air filter clean as the bike needs to breath with it being a 300cc and the air box a stock size for a 125, 200, 250, 290cc. The air box really needs to be bigger for the 300cc. I am working on that one! Mmmm... Billy

Hey Ron Thanks for the info. I rode a trial on Sunday @ 6400ft elevation and the bike ran flawlessly. Lots of power on tap. I used a .025 wire diameter on the diaphragm spring. I keep the .025 wire diameter in even at 800ft elevation. No slide bounce with this soft spring on drop offs. The big change was the iridium plug as it really cleaned up the spark. I am happy with the jetting now.

Hey Jim Why the change in jetting? I would guess you are riding in Michigan under 1000ft elevation. I am riding anywhere from 800ft > 6400 ft elevation. Quite a difference indeed. When one gets a bike from Beta it will be jetted rich to make sure that a customer does not lean seize the bike. Basically Beta does not know where the bikes will end up once bought i.e. elevation, humidity, temperature so they error on the side of caution. The stock CV carb spring is too strong above 1000ft elevation. When riding at higher elevation the spring in the CV carb diaphragm presents too much force for the thinning air witnessed by the bike responding poorly when the throttle is cracked open. By you asking to tame the bike down I assume that you have experienced the opposite? Have you played with the two stage mapping switch under the side panel? BillyT

Darrel This feels nothing like the Scorpa. The Scorpa felt lighter, quicker responding, built confidence. The key word is felt lighter when trying to hop, float. The Beta 300cc 4T runs great, and well put together I think it is more of a weight/balance/distribution thing. The other is that a 300cc four stroke actually gets too much traction on BIG Sticky rocks as opposed to a two stroke. Since it gets more traction on the sticky rocks it fools you into thinking it can go up anything and that makes one try bigger things than one normally would. That is when it bites you in the ass. It needs more run on or RPM's to shoot up bigger rocks. It simply does not rev out that quickly compared to a two stroke. This gets me in trouble. It is not a matter of simply pulling the clutch and rev the crap out of it and then dumping the clutch, that will get one tired real quickly. There is one more thing I found out DO NOT BACK OFF THE THROTTLE going up big rocks, a little thing called engine braking will bring you to a quick slow down and then fall down LOL On a two stroke one can back of the throttle on a big up and then coast over the object, kind of like point and shoot. On this bike, point, twist throttle, let clutch out and hold on (and hold throttle ON) until the object is in your rear view mirror so to speak. I have the jetting @ # 20 Pilot, 112.5 main, CV carb spring changed from a stock .027 spring wire diameter to .025. I am riding at two elevations 800 ft & 6000 ft and this jetting works great for both altitudes. I have changed the plug out to an iridium plug and that has made quite a difference in how it starts and runs. It is all maybe perception, but time on the pegs will tell. How are you liking yours compared to the Montesa & Scorpa? Cheers BillyT

Hey Mark, yes my timing is all messed up now on this beast. It seems like your brain is thinking ahead and the bike takes time to re-act. I am learning to ride all over again. Maybe that is a good thing as I will drop all of my old bad habits LOL I tried what you told me on the You Tube posts. It would only allow me to post one at a time. So Mark, when are you going over to the dark side? LOL Cheers BillyT

I promise the last video

Sorry. I just copied one of the links i.e. www.youtube.com/watch?v=a2FHl-KJwp8 and then pasted it in on the front page of You Tube and it opened just fine? Copy a link and then paste in You Tube. Maybe there is a better way of posting it? BillyT

Hey guys. I did it, I went over to the Four Stroke dark side. I played around with the carb and re-jetted, re-sprung the CV carb slide. The four stroke is messing with my timing & mind for sure. I am now back at square one learning all over again. I posted some You Tube (3) videos of me playing around on this BEAST . www.youtube.com/watch?v=a2FHl-KJwp8 www.youtube.com/watch?v=2gJXGjB6eC4 www.youtube.com/watch?v=OqpPFM5qYvw Not good riding skills but fun non the less. Cheers BillyT

Sam What is the latest with the 125cc project? How is the bike running now since the changes? Hopefully you are a satisfied lad? LOL..... BillyT

Hey Cope You have a new friend with crossed hoses. I did not know you where gay! LOl.............. Maybe you can syphon his hose for him in Oka. See you in Munester in June hose man. BillyT

Ralph Thanks mate. I will no doubt tear into the CV carb when the bike gets here. Mostly to satisfy my curiosity and will call my mate over at Mikuni to get the low down on the CV carb. Stay tuned as need more help adjusting to a four stroke! Cheers BillyT

Steve Where did you send the message to? I sent you one a couple of weeks ago, did you get it? My e-mail address is williamtraynor@hotmail.com Cheers

Hi Cope Yes a new 2010 Beta Evo 300cc is on its way from American Beta. Apparently the bike has changed much since 2009. My mate is the VP of Mikuni in Northridge CA. known him for about twenty odd years now. He will be getting a call from me on Monday with me asking for every bit of technical info on that carb and any secrets that the lay man does not have. I will no doubt share it with my bros here. I have spoke with the new importer at American Beta and he is an old trials rider so he should be very helpful to all who buy a new Beta.

Oh but there is! Much to learn. I have access to much at Mikuni and will exercise that. You may not have a need, there may not be a need but a desire for education on a new type (at least to trials bikes) of carb. To each their own. Respectfully BillyT

Hey BE4T guys. I have went over to the dark side and ordered a 2010 Beta 4T 300cc. Getting excited now and looking forward to feeling what all the buzz is about. I called my mate at Mikuni and asked for all of the Mikuni carb specs and an education on same. Look for future posts seeking help with this new to me 4T beast. Cheers BillyT
