4 Stroke Enduro Must Have Part

[@mikehunt4686]

I have a 07 450xcf that is carb and have tuned to run with low end power delivery in slow narly single track. So much fun..... Soft progressive rate rear spring 13-52 gears.... If you set up the 450 right contrary to what many say is awesome tight single track👍 Test drove some new ones didn't like em.... Couldn't really tune em.... But now see that it can be done effectively.... Thanks👍

[@EverySingleSunday]

Ya, the gearing helps in the slow but I’m doing a 1600 mile Baja Trip in October so I can afford to gear down. Some days are slow Rocky stuff, others are 80 MPH highway for 40 miles. Going to try and make it hit all the marks The carb bikes were so much easier :)

[@trailbossvoss]

Well u got me sold my 500 cuts out right when I need it the most thanks for a great vid

[@EverySingleSunday]

A tune, a DeSmog, and a muffler will transform your bike. 35 HP becomes 50 and it runs so good

[@trailbossvoss]

@@EverySingleSunday thanks man I give it a shot

[@EverySingleSunday]

Have fun Depending on the year of your bike you may just be able to have Twisted flash your stock ECU. Give them a call. They sell and stock Vortex stuff as well

[@sumojames3540]

Look up taco moto on KZbin I'm running a taco tuned Athena GET ECU from him the bike is a ripper. No flame out no funny stuff like that and will rip your arms off if you want it to. Mike is super knowledgeable and knows his shit.

[@trailbossvoss]

@@sumojames3540 sweet dude thank you will do

[@rz350yam]

Very good demonstration. Well done.

[@EverySingleSunday]

That man. It’s a huge help on the bike

[@UnEmmerdeur]

Nice video. I always like it when someone else tests the expensive bits. I found perhaps a much more economical fix. These KTM/Husky/GasGas 450's have had a flameout issue for many years. Usually a Rekluse fixes it. Rekluses transforms these bikes big time as far as rideablity goes IMO. I have owned several KTM 450 XCF's over the years. Purchased a GasGas MC450F with a Rekluse which did not fix the issue. It would still flameout at the strangest moments. I knew that GG's come with fairly restrictive air boxes compared to its KTM cousin and as you have stated they seem to not run that well off idle. I did a test by removing the air box cover and tried to get it to flameout similar to what you were doing in this video. Could not get it to flameout. Put the stock air box cover on and within 30 seconds I was able to get it to flame out. Instead of drilling holes in the stock cover I ordered KTM Part # 79106903000AB which is the vented cover that comes with the newer KTM's. Fits perfect. Went out on an extended ride and could not get it to flameout and it generally just ran better off idle. Put the stock cover on to wash the bike and as I was riding to my truck, yup you guessed it, had one flameout. Anyway my 2 cents. Keep up the good work!

[@EverySingleSunday]

Sorry for the late reply. I will not run a bike with an auto clutch on it. I hate the lack of feel and the ability to have the bike hold itself when in a bad situation. It also breeds bad habits of not covering the clutch while riding as 99.9% kf auto clutch riders do not use the clutch anymore A ECU is the correct way to fix a flame out. It does more than just fix a flame out. It makes the bike run better all around and makes more power as well I appreciate your input but don’t agree on the auto clutch recommendation

[@FamousLive11]

You have outstanding Balance Skills

[@EverySingleSunday]

Thanks mate. Lots of practice

[@racesla]

Great video. I need to look into that upgrade or remap on my new Sherco 300 sef factory. Love the bike, but the slow speed flame outs are killing me. Literally lol.

[@EverySingleSunday]

I know the feeling. The bikes are so sketchy on rocks , tight spots and all that. I fell off a few things before I figured out what I needed to fix it. Have fun man 👍

[@moonzy11]

what year sef300 do you have ? I have a 21' this would be a cool mod

[@racesla]

@@moonzy11 2021 also. I took the quiet core out of the akrapovic exhaust and just have the spark arrestor screen in. Definitely flaming out less. Better flow, leaner, who knows? lol And really not much louder. Next up is getting the front suspension dialed in. Pretty harsh in the bony single track and deflects quite a bit. Which surprised me a bit with the KYB fork.

[@moonzy11]

@@racesla thanks for the tip

[@mandyandmaxbird2780]

I am havi g flameout issues on my sef300 was thinking its my poor skills but it keeps happening

[@mikenkaleigh]

I am guessing gas gas still doesn't have tuner app in 21? I have a yz450fx and I trail ride, I have found low ide and retarded timing really help cause flame out. I came from a yz250f and really needed to tune my new yz450fx bike down until I got more comfortable. I tried taming it with the tuner app and that did help but the yz450fx just wanted to rip my arms off in the slow stuff and just take off with the insane torque. The #1 most helpful and worth every penny was to get a g2 throttle tamer. 100% completely changed the bike. Completely tamed the first half of the throttle, and made ide way more controllable. The best part it is only 80 bucks, which is nothing in the world of dirtbike parts. I got the bike I did because I am on open fast flow trails (old access mine and oil roads) most of the time, and on the public roads a lot between trails, and planning to go to California this year and they are going after 2t and not giving permits. Now I have a bike that is controllable and with tons of torque on demand down low to haul my 220lbs up hills.

[@ironthumb3048]

Can twisted development remap any bike brand ECU and what does it cost?

[@EverySingleSunday]

Certain bikes can be remapped and others have locked ECUs from the factory. You would have to call them to ask which models can be remapped and about pricing

[@wfodavid]

Have the VORTEX on the 500.Game Changer.

[@EverySingleSunday]

Yes it is.

[@philipsmith6152]

Great video, does the TPS calibration work the same on a 300 tpi? Cheers :-)

[@EverySingleSunday]

I’m not sure. I’ve never needed to look it up before.

[@philipsmith6152]

@@EverySingleSunday looking to do the same mod on my 300, thanks

[@EverySingleSunday]

Look up South Bay Moto Performace in CA. They have some killer mapping, heads, and other parts for the 300s I’ll have all their stuff later this week and am excited to get it in my bike (Already tested it in a friends bike and it’s great)

[@85ZERO17]

WOULD THE NEW HONDA (RX) MAPS BE COMPARABLE IN THE DRIVABILITY ON LOWEND…

[@vince5946]

You just described perfectly how a Rekluse clutch works. I know you're not a fan but I'm just saying.:)

[@EverySingleSunday]

I love a rekluse and think they make great clutch components But no way I would run an auto clutch. They are dangerous in technical situations and take control away from the rider

[@EverySingleSunday]

Also, while an auto clutch may keep it from stalling it doesn’t help with the mapping at all. They still run like crap down low from the factory

[@UnEmmerdeur]

@@EverySingleSunday With a properly setup Rekluse you shouldn't even know its there until you need it. Works like a normal clutch except it won't stall when you mess up. If it is taking control away from a rider it is not setup properly.

[@PriapismSD]

Do you think this mod will bring a 4s 350 or 450 to response level close to a 2s like a 300 for McCains, etc? My KX450 is horrid on on tight rocky trails, but wonder about getting a 300EX that would not be good for tracks also

[@EverySingleSunday]

The 300 2T is like a diesel and is the best for rocks and tech. I think a KX with a heavier flywheel/ clutch weight and some proper tuning clubs be very good. But not as good as a 300 built specifically for that That being said, the 4T bikes are definitely better at the track

[@PFCwhiteUSArmy]

Did the idle get raised 50-100rpm?

[@EverySingleSunday]

I didn’t notice a difference. On the 4T bikes there is an idle screw you can adjust

[@user-xl6vt7ev2s]

Hello travis will this work on a Crf250f 2021

You do a heavier fly Wheel on your 450?

[@dadmode5545]

@@EverySingleSunday had one in my 2020 FX450. The change wasn’t worth the work to press it in, however, I also didn’t have it mapped. Stock ecu

[@EverySingleSunday]

Well, you can add a weight to the clutch side (what I’m doing) Take about 10 minutes to install I run one on my 300 and absolutely love it 😍

[@dadmode5545]

@@EverySingleSunday the two strokes do well with the clutch side weights, 4 strokes are more aggressive on the clutch with a weight so they break down faster. I guess it’s not that big of a deal since changing a clutch is still way easier than pressing on a stator-side weight 🤣. Which one you putting on the 450?

[@EverySingleSunday]

I hadn’t heard that before I will be installing a 7oz clutch weight from Blaise Racing. It’s the same one I’ve been running for years in my 300s

[@Michael-yq1em]

Did you mess up the title for this video? it's just about the ecu

Not at all. It’s the 1 part that is needed for a 4T to work off-road

I’m surprised KTM doesn’t offer full fuel and ignition timing adjustments the way Yamaha does on their dirt bikes.

[@Moneypress11]

I hope you try and take your 450 out on some single track. I’d love to see opinion. I use my 19 450 xcf for everything. I have a vortex tuned by my local shop and it’s the perfect overall bike. Use it for all types of trails. Single track, enduro, sand dunes, Deseret, Timbersled and more. Utah has all types of terrain and I’ve found the 450 is best overall.

[@EverySingleSunday]

I’ve run it stock for a few rides and it wasn’t that great in the past. With this new tune I definitely will be getting it out more. We’re actually going to start a whole new build with Dirt Bike Magazine and this is going to be a project bike

[@rztrzt]

Don't see why ktm can't give you a programmable ecu from the factory...

[@EverySingleSunday]

Ya, I know the 21.5 factory bikes let you play with fueling. So I’m assuming the 22 bikes should have something similar I’m curious how much it will let you tweak it and if it’ll be enough to make a difference

[@Lostonabike]

This is possible on a 250 but not on a 450 this was really impressive!

[@EverySingleSunday]

What do you mean? This was all on a 450 in the video

[@Lostonabike]

@@EverySingleSunday yes that’s why it was so impressive because the 450 is very hard to keep running without that ecu so it’s an unbelievable gain those pivot turns and when you let off the throttle going up that rock it’d definitely stall this was a great video vortex ecu is hard to come by in years past though
