The $1300 KTM 450 Is FINALLY Fixed (MYSTERY SOLVED)

[@TheRealCozy]

Crazy I been watching you for like 3 years now. You’ve came a long way since then you and your wife. Congrats fr im gonna keep on watching and supporting. You help a lot of young mechanics out

[@stoneyoutdoors8819]

ayyy i was right, i had a yfz give me an issue like this except way more extreme, would run fine in neutral but if you kicked it into gear would die instantly, love watching your videos, as a quad and dirtbike mechanic its good to see other peoples experiences, my uncle always taught me "smart to learn from your own mistakes, but even smarter to learn from someone elses" watching your videos has given me experience i would have never got if you didnt go thru it and record it so i can watch, amazing work man

[@robinbrowne5419]

For measuring a low resistance, like a coil of 0.3 ohms, we need to subtract the resistance of the leads. Touch the two leads tightly together and measure the resistance. The leads are usually around 0.2 ohms which should be subtracted from the coil reading. So if we measure 0.5 for the coil, then it is actually 0.3.

[@sendit1158]

Do you think it could be the wrong pipe? The exc 400 came with a twin pipe outta the engine didn't it? This bike is single pipe

[@theWILDANIMAL42]

Joe has so much more experience and knowledge than me but I love the DIY feel. I feel like I could do what Joe does just because he’s so casual about everything. But I don’t have a cool garage. Or big field to test stuff.

[@dubaitacker6347]

if im honest i dont think you have got to the problem, your running a smaller than factory jet to compensate for the leak in the carb mid body gasket. That internal leak will only get worse as the gasket turns to more mush, the RFS engine has a fearsome top end power punch which doesnt quite seem to be there. Open the float bowl remove the floats and you will see 2 small screws the hold the top and mid body parts together. What you will see between the two parts is a very old mushy rubber thing that was a gasket 20 years ago. But fair play you got it running much better but i just know from the 4 KTM EXC bikes i have owned with the RFS engine and the series 1 FCR slant carb have all had the same problem. And while im being honest its dam near impossible to fix even though you can sometimes buy the gasket required, it was never meant to be pulled apart. There are a few gents in the States who can fix them and they can be found on forums. Myself i tried, i failed and brought 4 very expensive replacement carbs.

[@dubaitacker6347]

@@acmautodiagnostics8273 yep 100% i am really sure that the mid body gasket is gone, i have done just what was done in this video. And im just trying to help as removing the carb is a gaint pain on these bikes. Yes the jet change helped at mid range but though hard to tell on video but the top end on these bike has a big old punch. It had leaned out with that jet and clip position, raising the clip or as the dude said 165 jet will help. i just cant help think the leak wont remain constant it will get worse and then you start chasing again. Internet is awash with the mid body gasket info and as you pointed out the slide wears the carb body out then they are junk at that point.

[@MaNNeRz91]

@@acmautodiagnostics8273 you realise stock jets could be way off because the factory where it's tested before leaving the line is at a different elevation and climate. Guarantee anyone who buys one that lives near the factory don't have any issues 😂 I don't think this is a leak issue because it's too stable when he holds rpm. A leak would be inconsistent. I think the needle is now too lean and the main needs to go up a touch

[@Daniel456324]

Electrical Engineer chiming in here. When reading resistance of coils and wires, you should always attempt to ground out the coil to dissipate any parasitic charge build up by the coil and capacitor before making resistance measurements. Just a tip, when measuring below 1 ohm or low resistance values, you must anticipate the lead resistance of the actual instrument leads to account for all the resistance in the circuit measured. Usually on top end meters (Fluke 87V, Brymen, etc) they have a REL function to cancel out this. Usually it's 1-2 ohm. You short out the leads, hit the REL function, then measure. That way you have a dead accurate reading. Anyways I love your content and hard work! Keep up the good work!

[@dannyjamison8337]

Something is going on with that carburetor making it too rich. Stock jetting is 175 main / 48 pilot. If yours had a 172 main, someone had already leaned it out. I would tear that carb down and find out why it doesn't run on stock jetting

I agree with the mid carb leak comment. Seen this many times. And you should learn to test your coils. A resistance qnd ohm reading can tell you a lot. The carb was never ment to be taken all the way apart. I did fix one ounce by making a gasket from a bicycle fat tire inner tube. But I didn't fix the other ones when I tried. Good luck man.

Environmental issues apparently.Take apart so many times before filing in circular file from half court. Good luck Joe

@@georgepidick9967 but it's just like anything, if you figure it out then you can fix,work on and improve. In the mid 80s the over engineered KTM was dominating the desert racing scene.

[@markmartin01]

Yeah, that's not fixed. The high idle followed by dropping idle is an indication of lean. Did you put that junk autolite plug back in it? I've seen those not burn under heavy fuel load. Fouled plug could also be explained by plug not able to handle the load of high RPM. In which case, original jet would have been correct.

[@AlfredDawes-p9x]

1) You say, you've been through carb 4 times? 2) Have you been doing this on the bike or tearing down carb absolutely to body, verifying all orifices, passages Circuits & Float Level? 3) If you went that far DOWN from 172 on the main jet from stock to get engine to clear out, You, still have an issue, 175 is stock. 4) You need to verify existing jets for not having been drilled or resized. 5) Accelerator pump rod needs the rubber bellows boot to keep dirt/H20/debris etc. out of rod actuator accel pump system. 5) Idle sounds way high also....Where is the mixture screw set? Carb Specs per Haynes KTM-RFS (Racing Four Stroke) SOHC 00'-07'. Haven't compared for accuracy, to my 2002 KTM Factory Manual. 2002 KTM 400 RFS (Racing Four Stroke) EXC Keihin CR-39: Mixture screw base setting = 1 turn out (400 EXC, MXC, SX, 520 SX) Main Jet = 175, Main Air Jet = 200, Idle Jet = 48, Idle Air Jet = 100 Starter Jet = 85 Jet Needle = OBDTM Needle Position (all 400 RFS) 4th from top Idle Speed 1400-1500 RPM

[@superslyko123]

Experience talking here. I had a 2002 KTM 300 for 4 years. I know. It's jetting. The KTM is very finicky that year. I could tell the difference in the bike in a simple change of elevation. I can hear the engine is still rich in the elevation of the needle jet. Raise the clip in the notch 1 or 2 levels & that thing will rip. Eliminate the hesitation. Leave all the other jets alone. I even created a data base of which combination worked best at which elevation. KTMtalk will help you too with step by step, pictured, numbered instructions. Good Luck! 👍

[@MrAndyloz]

Hi , where are you getting your resistance readings for you coil from please

[@colby_graba]

I know this is 6 months old but I would agree with some of the others posts. Definitely rebuild, new seals in the mid plate, make sure your accelerator pump is squirting correctly and at the right time. A lot of people do the Eddie Mod on the FCR1 carb because there is no real adjustment but with a lot of playing around and patience I was able to get mine perfect. Also while jetting the bike I have read you should really do that with the accelerator pump disconnected but I am certainly not a pro. I am just a guy with an opinion, trying to learn the best I can and most I can. The only way to do that is try and fail then you try and fail again. I restore old cars for a living but I love working on bikes, quads and anything with a small engine. It’s stress relief for me and invigorating when you get them running too notch!

[@saideragaming]

Those gloves seem pretty good but maybe a bit loose on the finger tips, so I got a glove recommendation: Maxiflex 34-874 black dipped nitrile. They have different types but my favs have gray fabric.

Save yourself time and invest in some electronic diagnostic tools and an exhaust gas analyzer. In the early eighties, I invested in an ALLtest tool. Within a day, it fingered a car with a defective alternator, even though nothing showed as being wrong. A bad diode. Back then most cars still had points. The Alltest would flag a distributor that had worn lobes (dwell variance). You can often take an old PC and convert it to a testing tool with some interfaces. Then you can test under load. Exhaust gas analyzers can often be found cheap.

[@AlfredDawes-p9x]

Your 1st video indicated fuel leaking out of carb after sitting for 5 minutes. That is a sign of float level issues and/or needle seat gas flow valve not seating properly. This will make an engine run rich as you have found from Plug inspection, by Main re-jetting carb down, & raising clip lowering needle from OEM position. From looks of "Lay of the Land" around your test area, I would think you are at or near Sea-Level. This would make me suspect of "Carb having been Rebuilt" by PO, having been done properly or just float level/needle seat issues. The carb also has the aftermarket Power Now Blade from Scary Fast. I have this on my 02' 400RFS MXC along with the Accelerator pump bowl. My bike uses same carb and runs great with Stock 175 main jet. Your bike does have either aftermarket header or the later exhaust header, as all 02' 400RFS motors had the twin header. Enduro Engineering had a lot of aftermarket goodies for these bikes.

[@cheekkeith74]

I wish I could've swapped ot the jets on my twin carbed 750 shadow like you can on that bike. I couldn't tell you how many times I pulled that sucker out and rejected after slapping velocity stacks and exhaust on it. Only to find out the diaphragms were pinched... but I'm a pro at it now! 😎

[@elguitarista9487]

measuring resistance has a number of important points to note: 1) meter must be calibrated by putting probes firmly together and noting the error reading, which must then be deducted from the component reading. 2) resistance is only a guide, and when checking coils, inductors (chokes), inductive sensors and transformers, the value of inductance (Henries) is more important. Exemplia gracia.. an inductive pick up sensor may have a reading of 5 ohms and 500 turns (windings). If 1 winding is short-circuited, it would would be impossible to read the resitance (except with an LCR analyser), but would quench (kill) the value of induction, rendering the sensor useless. I love bikes, electronics, machining, fabrication/welding, inventing and.....!
