    Making a great trail bike - 2018 150 XC-W ??

    Good thought on the Freeride. It looks like a blast for trail riding. Not for jumps or mx track. Here are some videos that seem to fit the situation perfectly: https://www.youtube.com/watch?v=G26fBbupfc8 https://www.youtube.com/watch?v=EIsD6qQEpjg&t=321

    Making a great trail bike - 2018 150 XC-W ??

    The 150SX feels shorter than the 150XCW because it is narrower at the seat and tank. The smaller, opaque fuel tank with no reserve on the petcock is not as nice for long trail rides, though. No headlight, either, but I don't find my light too useful in the woods at night (front wheel - and light - is never pointed in the direction of travel). Don't write off MX tracks just yet. They are a blast. My first time on a mx track was at 50 yrs old. No racing, just having fun with other novices on track practice days.

    2 stroke trouble

    Sounds like your float valve is leaking if you have to turn off the petcock all the time. You should not have to do that except when trailering the bike. It may simply have crud from the tank or from the fuel line stuck in it. I mention the fuel line because the original fuel line on my bike disintegrated on the inside and was putting little pieces of rubber in the fuel bowl (and one time clogged the main jet which is when I discovered the problem). I am surprised, though, that you didn't mention fuel running out the carb overflow and onto the floor. Are all your carb vent lines clear?

    Premix oil

    You can buy directly from them. I do. If you buy a lot of oil, you can save by becoming a preferred customer directly with them ($20/yr fee I think) and you'll get discounted prices. MLM is pyramid selling, not a pyramid scheme. Big difference between those things. Pyramid selling is a method of paying dealers/salespersons and is completely on the up and up. Changes in oil ratio does make the mix more or less lean but by not by as much as one might think. Here is an example: Initial mix 60:1. That means there are 61 total ounces (60 gas + 1 oil) with the gas being 60/61 = 98.36% of the mix Change to 40:1. Now the gas is 40/41 of the total = 97.56% of the mix 97.56/98.36 = 99.19%, meaning a change to 40:1 decreases the gas content by only 0.81% (less than one percent). Comparing it to re-jetting for altitude changes, a 250 ft difference in elevation has a 1% effect on air density. So a 1% change in fuel mix should equate to about 250 ft in jetting specs, right? Are those of you are "performance seeking gear heads" who have made big changes to your premix ratio seeing a larger effect than that, as compared to your original perfect jetting? I am not one of those folks, I am one of those who is happy if the bike runs relatively good. My fun is in riding, not re-jetting whenever the temperature (or altitude) changes. I run a little rich to be on the safe side. More obviously, going from 60:1 to 40:1 = a 50% increase in oil in the mix. That's a big increase.

    has anyone here ever removed their lectron?

    I had one on my 2013 250XCW for a short time this past year. Compared to the Keihin, it had noticeably less low end torque. I was able to live with that (I do not race). With a little adjustment, it felt pretty linear across the board, better than how my Keihin was tuned. I found myself going faster without realizing it. It had problems with the idle changing if pointed down hill. It would stall going down steep hills. If I adjusted the idle up, it would eventually recover from that low idle and then the idle would race and I'd have to turn it back down. I sent the carb to Lectron and they did some mod that pretty much fixed that problem. Good enough anyway. It had a hanging idle. I tried richening the rod until it blubbered. I tried leaning it until it bogged. We are talking multiple turns, 1/4 turn at a time. I tried a different rod. I could not get it right. I put the Keihin back on several different times and it had no such problem. In the end, I spent more time messing with the Lectron than I had in the 3 prior years with the Keihin. It was cutting into my riding time. I put the Keihin back on and, other than a little time spent playing around with tuning to see if I could dial it in a little better, I've not touched it. I wish I could have figured out the hanging idle and kept the Lectron but that's not how it ended up. I sold it to keep myself from swapping it back on and spending more time trying. Edit/additional: Others have had great experiences with their Lectron carbs. The company has good customer service. Maybe it is something about my bike that the Lectron doesn't like (I also replaced the reeds, no help). I really liked the linearity and the promise of it staying in perfect tune across changes in weather/temperature.

    Dealer question

    JT Motorsports in Frederick MD has been good to me. Their website shows a 2017 300 XC in stock. I don't know how they make their money but they did not tack all those extra fees onto anything I bought. When i bought my 2013 250 and my son's 2014 85 sx (both current model year new bikes at the time), they added $100 for "administrative fees" to the list price. I've never bought a KTM anywhere else. I thought that was how KTM dealers operated and it was so refreshing after buying Hondas and other bikes in the past and getting sticker shock from the additional fees. Hopefully they still give those great deals.

    Gray gear oil help!

    Looks like water to me. My son's 65 would do this whenever he went through water, and I'm not talking deep water. It would take a few oil changes before it would go away. I suppose it could be coolant but you mentioned riding through a river so I would bet on it being river water.

    New bike feels skittish wobbly

    Because standard trail bikes are not capable enough. I ride for fun, not competition.

    New bike feels skittish wobbly

    You didn't say what your buddy's bike was that felt planted and controlled. Was it a different brand? I will preface the following by saying I am a gumby, not a racer or suspension tuner, but I am an engineer and have been wrenching on things for a long time. I always felt my bike (2013 250 XCW) was skittish and the front end often felt like it was going to slide out on flat turns and especially in gravel. It also would get headshake at higher speeds under heavy acceleration. I tried everything that was recommended and some things that were not on the clickers and sag and height of the forks in the clamps, etc. all to no avail. I was able to make it handle worse, that's for sure, but was unable to make it more planted. Then I bought a steering damper. Big difference. It totally changed how it feels. Some might say it I simply masked my poor suspension tuning but, if so, it worked.

    Lectron feedback/opinions?

    I bought one for my 2103 250XCW. It ran great (smooth power but a little less grunt on the low end) but it had a hanging idle that would not go away whether I leaned or richened the rod. Lectron has tried to help and they did make it a little better with a mod and they are willing to keep helping but I have given up on it for now. I bought the carb to get "perfect" jetting all year round but I ended up having to mess with it so much and I swapped it (and my modified air boot) in and out so many times that I got tired of it and went back to the Keihin. I spent more time on it than the years worth of summer/winter jetting changes I was trying to avoid. Others seem to have no problems. I don't know if it is a problem with my bike or the carb. I haven't found anything wrong with my bike. The Keihin doesn't have a hanging idle but it may just be more immune to it. I have also read that maybe a different rod for the Lectron might fix it. I don't know. Maybe when I get less busy and maybe if I feel like spending money for a different rod I will take another stab at it.

    Ktm 125 keeps blowing seals

    A vacationing penguin is driving his car through Arizona when he notices that the oil pressure light is on. He gets out to look and sees oil dripping out of the motor. He drives to the nearest town and stops at the first gas station. After dropping the car off, the penguin goes for a walk around town. He sees an ice-cream shop and, being a penguin in Arizona, decides that something cold would really hit the spot. He gets a big dish of ice cream and sits down to eat. Having no hands he makes a real mess trying to eat with his flippers. After finishing his ice cream, he goes back to the gas station and asks the mechanic if he's found the problem. The mechanic looks up and says "It looks like you blew a seal." "No no," the penguin replies, "it's just ice cream."

    New Lectron Carb bogs

    Here is the way I understand it and what I did on mine: If it bogs in neutral from idle when you do the "whack the throttle" test, the rod needs to be richened. A 1/4 turn adjustment may be all it takes to go from bog to no bog. On mine (on a 250) , it was fine at one adjustment and bogged really bad when 1/4 turn leaner. If it bogs at speed when you suddenly open the throttle, richen the power jet (the screw on top) until it quits bogging. Mine was something like an additional 1/2 turn out if I recall.

    Ring End Gap

    64mm piston diameter = 2.52 inch bore 2.5 x 0.006" to 0.009" minimum end gap = 0.015 to 0.023 inches of gap, minimum. You said yours measures 0.023 inches. That is within the bounds for the minimum end gap. I don't know what the guideline might be for maximum end gap before replacement but I would assume it is a good deal larger than that.
