Hopefully someone here can help me I bought this bike and it was in pieces this is my final step before I can ride and its driving me nuts to the point I'm almost ready to sell it. I have an 01 ktm 250exc I have purchased a new slave cylinder for the bike hooked it all up I gravity bleed the system until fluid came out closed the bleeder filled the reservoir pushed the piston on the slave until no bubbles came out anymore I then proceeded to bottom bleed a few times just to make sure. My handle feels weird like there is resistance yet with the clutch cover off I can see movement. I have taken the clutch out inspected the basket filed anything that could possibly give it any problems still nothing I ran it with trans fluid in it to try to free it up incase it was stuck still nothing. I have a lot of time and money in this bike and I am really started to wish it came stock with a cable clutch does anyone have any suggestions?
'19 350 EXC-F, de-smogged, uncorked, Vortex, Rekluse Many say and have said that the OEM fully hydraulic (oil fed) cam chain tensioner on the 350 motors can be prone to collapsing in certain low oil pressure scenarios and allow catastrophic engine damage. Is all this just overhyped garbage being re-spewed on the internets? (ie--maybe was an issue on older bikes but not in 2019) Being a modern EFI 4t it has the tip over switch and will kill the engine after only 8 seconds of potential low oil feed. I know Nihilo, Rally Raid, and Dirt Tricks make tensioners that could be smarter or more fail-safe at preventing collapse than the OEM design. Nihilo is a fully manual adjuster that also blocks off the oil feed port, sending oil that would feed the OEM tens'r up to the top end of the motor where it is more useful. It would require periodic adjustment. Rally Raid is also fully manual. But does not address the oil feed port. Also requires periodic adjustment. Dirt Tricks is basically the same as the OEM design but adds an internal spring and ratchet teeth to prevent collapse. It is self adjusting and is "set it and forget it" --Regarding the Nihilo: Not really wanting to tap and block off the port in my engine although fully confident in doing so. I presume you could remove the plug and return the OEM tens'r without issue if ever desired? It is ugly and basic looking and maybe bulky to get access for adjustments? --Regarding the Rally Raid: Very nice looking piece. I had contacted them and got mixed answers about the oil feed. Their design allows the oil that is normally fed to the tensioner to dribble its way back to the bottom end of the motor. Blocking the oil feed port is not part of their design/install. Has to be ordered from the UK. --Regarding the Dirt Tricks: I have concerns that the spring loaded/ratchet design could over tension the chain and lead to premature wear. The self adjusting is attractive, but not vital to me. And why bother being hydraulic if it is backed up with a spring and pawl design anyway? --Regarding the OEM: Hey---chill....obviously the guys at KTM know what is best for the engines they design, and would not be keen to warranty expensive motor parts if failures were frequently happening. Lets hear some insights? Lets talk oil pressure scenarios. Lets hear from people who have first hand experience with any (or all) of the 4 tensioner designs. Lets talk about engine safety, longevity, and wear with the different designs. And of course.....lets hear what you would do on your $11k 2019 model bike that you throw around, drop, and abuse, yet still care for meticulously!
