are they calling them 390's, 430's & 480's or 400/450/498 still? kinda like the new oddball numbers & losing a few cc's aint gonna change anything for 99.9% of the dirt bike riding community-quite the opposite id imagine! maybe a sign of the diminishing capacity times? very red bikes-maybe too red?! new 2Ts get a bit of love too which is good. kinda weird how they offer a 350 & a 390 isnt it when you can get a 430-seems it would cost more producing it than it would be worth/sell numbers? wonder if they sell many 390s as its in no mans land really? in saying that its probably my choice if i were to go a beta 4T!
cars left carbs years ago, for good reason(other than emmissions). altitude, emmissions, power, economy, engine potential, tuning etc, etc, etc... jump on, hit the button, go. i agree with kelly, fiddled way too much with fcr and pump circuits on small bores, they need all the help they can and FI on a 240/350 is the way ahead, not such a big deal with 450's as my old wr was good but small bore definitely benefit from FI, no question.
I note with fear in my heart, they list in the release 'a stepper motor' to maintain minimum revolutions and 'reduce engine braking considerably'! OMG, that's the thing that tried unsuccessfully to kill me on my TE
I wonder if they are talking about additional use of an IAC (idle air control) motor, common on throttle bodies, or something different actually acting on the butterfly? IAC is simply an automated air bleed, usually used to balance cold start enrichment for a stable idle.
for me no pissin contests with you guys over the for and not for FI, It would be a good option to have or not. I still wish my 2013 TXC310R had a carb, carbs still just feel more organic to me. I know scientifically all that is the tuning and how things are set up and FI is everywhere the dirtbike world was really the last hold out and maybe chain saws and lawnmowers....
oh yea for FI they need to add some sort of AP type device or a seperate function for rapid throttle movments, or go with dual injectors or something. The AP dumping that load of fuel in is what I really like about carburators. Snap.
If you enjoy carburetors on Betas, I suggest you buy one now because they are a soon-to-be item of the past. And I can see someone not appreciating efi if they had trouble with computers or inability to run a basic HST. For me, I would much rather tune an efi system on the computer than endlessly pull a FCR on and off, testing adjustments. You can't fix a carburetor in the middle of nowhere when you run out of gas. Efi can break down and it is usually from abuse. It's like everything else, take care of it and it will take care of you. The original Mikuni units work great when tuned properly as well as the newer Keihins. There is nothing wrong with the stepper motors on efi units, not even on the TE’s. (2010-2011 Husqvarna 449/511s have faulty wiring harnesses which were corrected mid 2012-13. These models have non-waterproof connectors and a zero loop feedback error which results in a cancelled signal to the throttle body.) When working properly, these systems provide an electric smooth operation unobtainable from standard efi. AP functionality is added to both JD and PCV. PCV allows a bit more precise measurements on the AP though.
Will the efi Beta 350 even make it to the states for sale? I bet we will see it in enduro cross but not much off road or out in the desert racing. IDK about their new motor sizes. Remember the guys getting their shorts bent out of shape over the 449/511 classification.
which is so silly. why dont you think the 350 will make it here? I also wonder about the EFI system they chose. Its a odd ball compared to most but given Beta seems to know what they are doing I bet it ends up good or would not be on the bike. http://www.synerject.com/2-3-wheeler/light-motorcycles-v6
I have worked with fuel injection my entire life (30+ years) and have no idea why anyone would want it on a dirt bike. Guys carry pumps, injectors, o-rings and filters with them on big rides. They even have a box for all that stuff now. http://www.motominded.com/products/fuel-injector-holder I could fit a whole shit load of jets and needle in there.
5700 miles never needed any of that. Not one hiccup from my efi. Only thing I ever even think about is the fuel pump. Buddys with KTMs and my buddie with the Te310, never dealt with any of that in thousands of miles. One KTM 350 needed a new injector at about 3500 miles as it has a lot of tank slag in the filter and injector was still running good but starting to sputter at high PRM. I have yet to be stranded nor seen anyone stranded because of EFI and I ride a ton with lots of people. The 310 I mentioned is used hard and out away wet and has over 4500 hard all off road miles. Seen lots of EFI 610/630's with 15K plus miles, zero EFI issues.
I'm with you Moto. All my EFI troubles were tuned into the bike ex-factory. As for actual failures, zero in 3600km/125hrs of hard running. I've stacked it upside down, thrown it into the trees, I've even dropped it in a creek so only the RH grip was poking out. It still runs fine all the time. I'm careful when I wash it with the pressure washer & I open the plugs & spray them once in a while, but it has been faultless so far.
Bikes are available for order now including 350 EFI, and will be here mid to late August. If someone would rather have a carburetor, I have a 350 Factory Edition in stock!
Idk, I thought the '14 350 RS wasn't sold in the states. This is the RR though, and it's their first efi bike. I hadn't had my 2nd cup of Peet's coffee yet. I am sure the '15 RR 350 will be a winner, and probably sell out soon as every body will want one.
^which compensates for a clogged air filter(unlike KTMs & others) so wont run rich i believe? thought i saw somewhere it adjusts for fuel quality also, maybe aftermarket exhausts also without remapping? sounds good?!
I like that they mention simple and low cost diagnostic tool. Beta probably needed to move toward EFI to be ready for future emissions especially for their dual sports. I had heard last year they had EFI ready to go, and it was actually cheaper than a FCR carb. Who knows, maybe they will be the first to DI a 2 stroke.
