Hey Jeff, just so you know people like me and my friends appreciate your videos, and you have helped a lot more then you’d ever know. Don’t care about negativity.
I know im asking randomly but does any of you know of a method to get back into an instagram account?? I was stupid forgot my login password. I appreciate any help you can give me.
Thanks for all the Great content over the years! You are definitely a true professional. I have one question, I remember you saying not to remove the float chamber on the Lectron Carb . I am wondering what you’d recommend for winterizing ? In the past on a standard needle carb I always drained the tank and carb. Probably being overly concerned but seeing that small amount of fuel sitting in the clear bowl gets me thinking . I’m not opposed to a fuel stabilization additive just hasn’t been part of my process in the past . Thanks Don
@@yzrider3326 You can shut off the petcock and let it idle until it runs out. The remainder should evaporate in a week or two because the Lectron is very well vented.
Thank you, Jeff. I appreciate you taking the time to explain how cold siezures occur. We ride on the ice in the winter and my buddy had this happen twice on his bike, both times we were stopped for a while, warming up our hands, then took off full throttle and whaaam! Cold seizure. Makes sense now. Always appreciate how thorough you are in your videos. Cheers!

Thank you Jeff, you are the GodFather of KTM maintenance & I try to buy my products through Slavens Racing to thank you for your efforts. The folks that work for you are also pretty helpful when I call.
Thank you for all that you do ive learned quite a bit from your videos please keep them coming don't pay those assholes any mind i had my 300 to lock up recently come to find out it was the bushings that the bendix go into they were completely gone i had parked my bike to take a break pushed the button click pulled out the kick start it was locked i thaught the engine had blown up by watching your videos i learned about those things even got them from you i also replaced bendix and top end since we had the cylinder off bike only has 52 hours on it a 2016 husqvarna te 300 thank you sir
Nice. I get such a kick out of it. To the point with experience and knowledge and if you don't like it or spin what I say, that's your problem. Thanks Jeff.
Really good informative video cold seizes is somthing iam aware of to my cost due to being late meeting my mates on a trail one day got on the pipe much to soon to catch them.that was a bad day 👍🇬🇧
Great video, I have a riding buddy that always fires his bike up and gives her a few hard revs and jumps on and rips it down the road wide open thru the gears. Less than 30 hours on the bike and now is experiencing problems with the engine, go figure, we will see what transpires.
Quick question Jeff: does the thermostat on the newer bikes aid in keeping temps in the operating range in colder riding climates? Thank you for all the great videos!
Thanks Jeff always informative! You stated in your video your trail tech fan is set to cut in at 188 degrees. Is that where I should be set on my 15 300XCW?
Hay Jeff loved the video. Do you have a recommended warm up process to prevent this, nothing scientific but a general guide? Also does the thermostat prevent coolant flow as the rads drop down into the 110s and 120s? Thanks as always.
I just start them and take off but ride easy until it warms up. I monitor the gauge but you could also feel the top of the radiator with a gloved hand. I don't know if it would fully close but it would reduce the flow.
Thanks for this! Do you have a “2 stroke 101 video” for people that are new to them by any chance? I recently bought a Beta 300 rr 2 stroke after having a ktm 400 exc 4 stroke for many years. I’m a bit paranoid to ride it as it is so different + slightly affraid of doing something wrong.
We see alot of this in snowmobiles. Its mostly from trying to ride hard too soon. The colder it is the more important the slow take off is. My 07 YAMAHA phazer 500 4 stroke is made up of basically 2 yz250f jugs side by side. Yamaha has tuned the computer to idle fast at 2700 rpm for up to 5 mins when real cold. The sled wont hardly move till its ready. A yellow warning light stays on till its ready to ride everytime i START the engine. Goes to show how important cold weather warm up is on snowbikes .
Jeff you are appreciated.. your tutorials are $pecial in $o many way$. One of your videos I didnt watch until after I screwed the power valve retainer screw 😳
The Koso gauge comes with a nice bracket. Trail Tech sells mounting brackets for their gauges. For the Trail Tech gauges I made one out of a piece of aluminum I bought at Ace and dug through a junk box and found the other one. The Koso and the tach are for testing and will be removed when I'm done testing.
I have one built into the radiator cap very nice! That piece of mind is great! I ride street between trails and it can get down to 100 degrees while riding street... I need to get a thermostat, I hope it’s not too bad for it. Usually in the woods it’s at operating temps but on my way home it drops. Since it was already hot does it matter less than when it’s just warming up?
Hello: The gauges in thermostats are very inaccurate and poor quality. They eventually fail and blow the gauge into the air and hot coolant on the rider.
What do you think about how new Polaris and Ski-Doo (maybe Cat, too, haven't owned one recently) snowmobiles run at 100-120 degrees at full operating temp?
Good question. The thermostat definitely helps, but if you pour the coals to it before it is warmed up you might still experience a cold seizure. Even with the thermo the engine will run too cool and have a negative performance effect. I have 3 tpi bikes, 2 with thermostats and one without. On a 40 degree F day they all need one radiator taped on fast flowy type trails and definitely on dirt roads or Jeep trails.
Definitely good tips warming it gradually so everything expands together. Sometimes hard to resist cranking it to clean it out, a few quick partial throttle wicks for that, but I always cringed when ever I heard people holding them on the rev limiter in the pits right after they fired it up! lol!
Your comment about richness based on being visually black is wrong in my opinion. 2 strokes will typically have brown and or washed out spots of clean aluminum if they are rich around the transfer port areas of the piston. Fully black indicates less fuel and less piston wash. This is my experience anyway. Feel free to correct me.
I put on all of my gear, hop on the bike, start it and ride off while keeping the RPMs in the low-end and lower mid-range until I get a few miles down the trail.
I am always surprised every time I head out to the bush for a ride and notice other riders start the bike up dead cold and rev the absolute crap out of it, or take off and just go straight to WOT. I thought it was common knowledge to let the bike warm up and ease into it...guess not.
Hey Jeff! Some guy said on another site said when he changed plugs on the tpi bike like you showed, it run horribly. Did you notice any difference? Thanks!
Scott: On the spark plug video a guy asked if he could use an NGK BR7ES. I responded yes BUT that is basically a lawn mower plug that I would not use in my bike but it can be used. Then a goon posted on his video that it made the bike run worse. Well, no shit, a 2 year old could figure that out but the goon wanted to be the cool dude. I recommend the NGK BR7EIX. I've compared it on a Dynojet dyno and there is NO performance difference.
@@slaverace1 thanks! One last thing. The Br7EIX plug, would you recommend it in a 2011 300xc? Would it run better than the BR7ES that's in it now, thanks!
@@scottgaskill4896 The BR7EIX is a high quality Iridium plug that has a stronger spark and less likely to foul and last longer than a BR7ES. I don't test with the ES so I don't know if there is a performance difference but I suspect there is.
Real great tips of engineering from you but ...... What a big fail for the orange brand, ... I love my trouble free 2012 300XC that have received two fresh top end in 6 years and still pull more then I can grip it but when the time for a new one arrive I am not sure I will go Orange again. At the price the sell bikes and with the 'READY TO SEIZE' new attitude, it is ridiculous to have to invest still those big buks to have it not better but just working. thanks for great tips!
Koso sells a finned extender piece that you can see in the video. They claim it extends the life of the Lambda. You are correct, the service life is shorter on a 2 stroke vs a 4 stroke but I just use it for testing so it won't get that much use.
Why is it that they can get an automobile to run at a consistent temperature no matter what the outside temperature is, and yet on these new bikes the damn thermostat can't even maintain a constant temperature? How ridiculous! They would have been better off just staying with air-cooled motors with all this complicated BS going on.
Yea you can spend a bunch of time fucking around with covering radiators or you could just leave the fucking thermostat in if you ride year round. I really don't understand the guys that take the thermo's out. Unless your riding in the fucking desert and running the shit wide fucking open on a highly tuned / strung engine and need every sliver of cooling you can get its just dumb to take the thermos out. Or if your a professional racer and want to minimize mechanical failures.

Cool Jeff this help me with my high cc chainsaws
Partially due tp lubrication not being as well established right after atart up for those of you guys running less than 40:1

Thanks again Jeff. Mum wants a video on hot flushes next please.
What do you think about how new Polaris and Ski-Doo (maybe Cat, too, haven't owned one recently) snowmobiles run at 100-120 degrees at full operating temp?
Why wouldn't you just leave the thermostat in, instead of messing with tape on the radiator?
my last ktm came with a plastic louver that fit right in front of the radiator for cold riding, it sealed the radiator the same way tape does

@@slaverace1 Thanks for the reply. Makes sense. I wonder what temperature the OEM thermostat is set for.
@@rlovell383
There is a number stamped on the thermostat in Centigrade. I think it was about 165F.
also, guys running ims tanks can't fit a thermostat on the 300/250's

so its a good idea to tape up a radiator if you are riding in really cold weather too keep engine temps up?
So best thing to do on a cold morning is to ride the bike on a slow pace for a few minutes till it’s safe to go full throttle?
Jose Sosa jr I’m assuming, I typically let it idle for a few minutes, then lightly cruise around for a bit
You are correct. If you're riding in freezing temps you need a temp gauge and block off a radiator.
You are the man!
Is this just a thing with 2 strokes, or can it happen to 4 strokes as well?
Yes it can happen on a 4 stroke but much less likely.
I know this is off the topic of the video. What front tire is on the bike in this video? Side wall is not smooth.
Your comment about richness based on being visually black is wrong in my opinion. 2 strokes will typically have brown and or washed out spots of clean aluminum if they are rich around the transfer port areas of the piston. Fully black indicates less fuel and less piston wash. This is my experience anyway. Feel free to correct me.

Which trail tech temperature sensor type would you recommend for the KTM 350/500 4T bikes? Radiator fin sensor? Hose sensor?
Radiator sensor. slavensracing.com/shop/water-temperature-digital-gauge-ktm-husaberg-trail-tech/
I let it idle for 5 minutes and then i do balancing practice at low rpm. Then its nice and warmed up
you set the trailtech fan to 188deg, do you recommend that temp for 300 carb models as well?

Does that also go for 4 stroke engine's
Four strokes are not very susceptible to cold seizures but it can happen.
good info
I would never tape my radiators. My bike already overheats pretty easily :D
In cold/freezing conditions they never get up to correct operating temps hence the need to block off a radiator.
Jeff Slavens my bike can over heat in +5 celcius soo xd I dont know about that
