They do. Based on my information, the UK EFI Ninja 250s have electronic speedometers (although the display is still analog). This gives them the potential to be dead on accurate.

But anyway, where's your video?

[Racer x]

this is my second try at the 0-60
Start at 4 seconds, the speedo hits 60 at about 11 seconds. There is a delay but it looks like about 7 maybe 8 seconds. that is down from my 9 second guess at the drag strip. I will be going to the drag strip next weekend . I cant wait to try again.

I used a stopwatch on your video. It was 7.76 seconds 0-60.

[Racer x]

Thanks., I know I can do better. I will change to a 14 tooth front sprocket and I also have GP shifting now.

[n4mwd]

I just got a new 15/45 sprocket set, but I haven't put them on yet. However, now that my carbs are working descent, I think I'll try another run before I put the 15T on. Maybe I'll lose the top case for the run. It probably has no effect, but it might.

[Racer x]

With land speed racing I have plenty of time to get up to speed. So I just sorta ride off. I will be at the drag strip next time . I will launch at 10000 rpm . That will be better for the 0-60 part.

I was running a 15 /44 for that run. I don't have enough chain for 15 /45. I will play with rear sprockets and a 14 from to see how it works out.

[alex.s]

i launch around 11.5 and i hear nemesis bouncing off the limiter when he launches but we dont have as much power as you do. and also nemesis loops his bike sometimes.

[choneofakind]

Eric, I'm sure your times will be faster with the GP shifting. From what you said, it should help you tuck.

yes. Do it!

[n4mwd]

I just did another series of runs now that my carb is working right. There was no real difference. It was still around 7.0-7.5 seconds. I'm not sure, but I think something may be dragging on the bike. I weigh about 220# with the gear so that could also be a factor.

[Jiggles]

I'm 200lb and still broke low 6s.

[etiainen]

You also had an Area P full exhaust, right?

[Jiggles]

Yep

[choneofakind]

Full muzzy, proper jetting, massive improvement in my times!!


It took me 6 seconds and 8 frames, which is 6.26 seconds to get to 60 that's down from 6.73. Even with maximum error, that's still much much better. I'll get video posted soon once I get a sound test video done for the muzzy, which is conveniently much quieter than the Two Brothers. Thank god.

Ah you bitch! You beat my 6.36 time! Damn you!

But imagine if my EFI had been installed when I tried it. Under 6 seconds? No problem

[Racer x]

Why do you think FI will be faster? The euro bikes have less power. Isint the throttle body like 28mm?

[Jiggles]

When you add the ecotrons EFI in place of carbs it adds a noticable amount of torque which translates to more HP which should result in faster 0-60 times. Though we don't have a before and after dyno so I can't tell you how much more hp or torque

Also, the euro bikes can't be tuned like carbs and custom EFI

[Racer x]

I want to see the dyno charts. I don't believe the torque increase with over all hp decreas will make that much difference. It will be fun to see.

[etiainen]

Eh...I don't think the ecotrons kit will be faster...

You should've put yours on first before crashing it.

There won't be an hp decrease

[Racer x]

I don't know what stock torque numbers are. I had 13 to 1 pistons . stock carbs Yoshi exhaust or a Nojema GP exhaust. I tried cam timing changes and ignition system changes. I got 33 or 32 hp and never got 20 ft lb of torque. Usually between 13 and 17 . I would love to know what the FI system gets with stock pistons. Torque is what makes riding fun.

I agree. The kit has a smaller pulley that creates a false sense of peppiness. There are about 5 guys with the kit installed so far and none have elected to take this challenge. I am hoping that @choneofakind will post his efi videos once he gets it running.

I would also like to see some UK OEM EFI videos. They have larger injectors so it would be interesting to compare.

Side note. I believe I may have found my drag problem. Bad tire pressure gauge. Real pressure: 20 psi each tire. Bumped it up to 28/32 so we'll see.

[etiainen]

I've been following the ecotrons threads.

Seems like you guys were really the guinea pigs for that round.

I was actually contemplating the group buy, but ended up buying the 'slowbr250' instead.

The problem with the other five guys is that we wouldn't have before and after numbers for them. So we wouldn't be able to see the difference

Power commander.

Need to figure out how to mount my crappy camera. If I'm slow though, it's prolly just me, not the bike.

Yes you can get a power commander to take control over the ecu but how will you know where max hp/torque is? You won't unless you have a dyno or rigged up some o2 sensors

A power commander is kinda like jetting, you gotta feel where it feels best. With a full EFI kit tho, you can tune spot on and stay there all the time.

Oh and chode once u get ur EFI kit you gotta give it a while to learn your perfect curve, then flip it to rich and break 6 seconds in a 0-60

[Racer x]

So is the bench mark 0-60in 5:59 ?

Also very true. I was on the fence with the group buy, but in the end, I made the wrong decision. The fact that every change he made to his new throttle body was based on my ideas or suggestions, and then then he excludes me from getting a new one, is very insulting. And if the ideas were that obvious, then why didn't he use them before he shipped them to the group?

That's where @choneofakind comes in. But even still, doesn't it strike you as strange that the manufacturer doesn't already have dyno reports to show for his own product? In any case, thanks to this thread, we already know where the various carbed models stand.

I bought a suction cup mount for mine. Normally it goes on the flat spot in front of the bars on the pregen, but for the test I stuck it to the tank. I was kind of amazed at how good it sticks. Eventually, I want a permanent mount. I have also used a DSLR tied around my neck with the straps which worked pretty good.

[n4mwd]

I think it was 5.75s on the pregen. But I'm rapidly coming to the conclusion that it was with a modified bike and not stock.

[Racer x]

That is the beauty of this thread. Let's see what they all can do. Could we make a sticky with the top speeds? With different catagories like FI mod and FI carb and carb mod carb stock and pre Jen stock and mod. And to make it really fun Honda 250

[choneofakind]

No worries Jiggles and n4nwd, I'll get some numbers posted once I have everything setup. I'm hoping for a solid week in learning mode before my track day to get it all set up so I can test out rich mode vs eco mode at the track, then do some more 0-60 tests.

Racer x, sure! That's the whole idea of this thread! Get to know the bikes better and see what they can actually do in the real world, not just those estimates that people have seen online. My best is 6.26, Jiggles is around there somewhere. Those are both with carbs, pipe, intake opened a little and stock gearing/tire combo. I'm betting on an improvement from my bike once I get rid of my airbox, go back to a stock sized tire (with shorter gearing) and get the bike fuel injected. I think sub-6 0-60 is very possible with the right setup. I just think it was very hopeful out of the box

[dubojr1]

Can anyone tell me how how to set up the KOSO for 0-60 times?

Not sure my bike will be good at this though. I running a 15/46, 4.5" rim with a 150 BT-016 tire but I'm also jet'd with slides drilled, no air box, full AP QC exhaust and a BRT running on premium. 220 lbs. before gear...

Could interesting to know though.

No because it's not marketed to improve performance.

[Racer x]

It could be. They could sell a race version with special maps . Using a 32 or 35 mm throttle body would be great. I can't use FI because the leaded race gas and nitrous messes up the o2 sensors .

Not to stray to far from the original topic but why leaded fuel? Just curious.

[Racer x]

Octain plain and simple. I use rocket brand fuel 112 octane and it is leaded. For my all motor run in April I used 100 octane. It has no lead. For the drag strip and this 0-60 challenge I will use pump gas

[Jiggles]

You can use FI without O2 sensors. One of the group buyers just put up a post explaining how he has customized his efi with no O2 sensors, just software.

[Racer x]

I could use a pre written map since all I do is full throttle passes. But the CR carb is 32 mm. And I love them.

[choneofakind]

I bet those 32mm carbs pull like madmen at WOT.

I bet the FI will be an improvement because the UK bikes have 28mm TB's and seem to be doing fine.

Anyhow, I haven't gotten around to getting my most recent 0-60 video loaded yet. Sorry. I don't feel like doing it today LAZY TIME!!

[Racer x]

I am hoping to go to the 1/4 mile track on Sunday. This will be the first time drag racing to go fast . Not just testing and tuning. I want to go 13.0 or 100 mph in the 1/4. I will video the runs to see the 0-60 time. And to see how I like GP shifting.

[choneofakind]

Sounds like fun! I hope you can blow my 6.26 second time out the window, even if it means I need to keep trying to get a better time. A little competition never hurt anyone
