2015 350 EFI vs 2015 390 Carb

[ricoyam]

The fuel shut off is quite evident in modern FI vehicles. It's not as bad with my 2008 Hypermotard as it was with my 2006 GT1000 which was still better than my 1998 ST2. By the same token my 2005 Mazdaspeed is hard to be real smooth with in stop and go traffic while my old twin carbied Alfa and Lotus were easy and smooth. I rode Chris's KTM 500 which has FI and it felt pretty good but it is also fitted with a Rekluse.
Like I said, it is the future but for now I'm sticking to a carb on my dirt bikes.

I had an 08 and 14 Yamaha WR450 in the shop. A few buddies where coming over, before the beers I asked them which bike would they would want for their own almost everyone said the 14. Why? FI was the first answer. Everyone took a spin on both bikes and not one guy picked the 14 over the 08.
They all said the throttle was too on/off. When you are looking for traction the last thing you need is a digital throttle.

Carb for me too.. In the real world where you are miles from anywhere in deep bush at the bottom of a valley.. simplicity and the better options of trailside fix makes a carb the best.. and carbs are the most reliable .. plus if you have to fix your efi what are you going to do miles from civilization.

For harescrambles I would be fine with it. Mostly flowing stuff, not too far from the truck, and good milage. For more tech trail riding I have no desire to ride a 4stroke with either fueling method. With the weight, heat, and the pop and die syndrome, why bother when the simple 250/300 2stroke is such a better tool for the job.

Poorly tuned I'd have to agree with you. The Beta FI is much like their carb tuning - a thing of beauty. If you wanted to get upset though all you would have to do is look at the wiring diagram. That's a lot of spaghetti.

Well i ended up with 2015 300RR (96h) with modded suspension to my weight by Race Tech

This is my first enduro and first 2 stroke. I have a lot to learn hehe

Every time I get stupid and think I might want a 4stroke I get a ride on one and come to my senses. To me its like a helicopter compared to an airplane. A modern 4stroke just doesn't want to run down low like a helicopter doesn't want to fly naturally. A 2stroke is just much happier in the places that make the 4stroke cough, die, and blow steam. I like the 4stroke on nicer flowing trail where its weight and planted feel can be considered an advantage. I rarely ride on such trail. The Beta 300 2stroke is the best gnarly trail motor I've ever ridden, it will run down so low and still pull you will be shocked.

Yes, i chose 2t for peace of mind, compare rebuilding costs between 2t and 4t.

And the type of terrain i ride is partially sandy singletrack with forest sections with roots and fallen trees. 2nd and 3rd gear when on the move. Gearing is 14/52 i believe. I really like the bike. I am very novice but i testrode and rented 4t Betas, Shercos, KTM-s and i liked 300rr most.

Cons

I drive 8km from home to riding grounds. 3km from it is tarmac and bike seems to vibrate alot trough pegs. 300rr is roaf legal here

When warming up the bike in yard its all blue haha.

I want to apologize for my comment I posted back last year. What I was trying to say was that carbs do have more moving parts than FI, and have their fair of issues. However, carbs are for more simple, and can be fixed fairly easily anywhere. Not true with FI - it breaks, and your probably done. I'm now possession of my new race bike - a '17 390RR RE. It's my 2nd FI bike, and the first 4T FI bike I plan to race. For techy woods riding, my 300RR can't be beat. It's amazing and I love it for techy riding. So, to the OP - congrats. You do the right thing and bought the perfect woods bike IMO. I do agree, its vibes a good bit. Some BRP handle bar mounts and isolation pegs will make a nice difference if you don't mind spending the money! I'm stoked on my 390RR RE, for fast and flowy, mx sections, and keeping it WO - its tough to beat I dialed 4t!
