    I would probably kick it 8ish times before diving back in.... you shouldn't be hurting anything if you did install correctly.

    That said, it sounds like you may not have primed the fuel line on reinstall? If not, there may be 3 potential issues: Air in the line, Your fuel pump may not be powered, kink in the line or improperly fitted banjo hampering fuel flow.

    Additionally, did you clean out the tank before installing? If not you more than likely also probably have lots of nasty plastic shavings that could also be clogging the pump or injector.

    If you didn't do either of these things I would recommend pulling everything, inspect filter/pump for plastic particulates, clean, reinstall with a primed fuel line and report back.

    These FI bikes should not need av or race fuel, unless you have done something to increase compression significantly. Detonation/knocking would be a sign of too low octane. Both richen the mixture and burn cooler than lower octane fuels. FWIW

    Another vote for kinked or loose fuel line in tank. It happens all the time. If it runs at all, it is probably not the quick connect being fully seated--another common post repair problem.

    @Retumbo7 @renogeorge


    Thanks much. Tank was cleaned by banging it and holding upside down (real scientific eh?) but not rinsed out. Fuel line and quick connect is good. The only thing I haven't really checked is the fuel pump as mentioned. The kid has been the chief handler of parts as I've been pretty unable to do much with my paw. Wouldn't surprise me if there was a small miss there. The simple stuff, right?

    Appreciated guys, will give it a go once I'm back home from travel.

    PS... no kicker on this 501. Hate not having one, I think it would be wise to get the kit and build up one of those capacitor things too. Until then, it's old school RFS technology to the rescue.

    I have a set of fork springs and shock spring for a 220-240 lb rider from a 2016 Husqvarna FE501 available. They came from Slavens and have about 10 hours use. PM me if you need them.

    To my knowledge the pre 17 EXC/FE used OC forks and the 17+ use XPLOR for both KTM & modern Husky

    Pre 17 husky used 4cs as did the 6 days ktm's. The other ktm's like exc and xcw used oc forks. Xc models may have used a different one but I'm not sure, they are different past 17 my.

    Hey, how's the foot coming along??? You able to ride off road anytime soon?? In sympathy with you and ZTRAB I decided to smash the shit out of my leyty
    The bikes we ride are designed to be run with 10% ethanol.

    I've run them on Ethanol free super and can honestly find no performance difference whether it be my 2 stroke 300 or my 4 stroke 450. I have however read where folks have put gasoline in their bikes that has too high of octane and running into performance issues. But hey, I'm no mechanic by any means, but it is what it is...

    Check all electrical connections. Red connector first...

    Sorry to hear about your injury, that shit sucks...

    It is about how they run at 90 + temps and how they run after sitting for 4 or 5 weeks with ethanol in the tank.

    Typically non-ethanol is the same octane as ethanol premium.. 92 or 93. unless you run race gas.

    It is your bike.. you can run anything you want in it.. even if you get flame outs you could always blame it on the TPS settings...

    You find those codes on your new front Goldentyre fattys yet?

    I just ordered and received a rear spring from Slavens for the weight category to carry luggage. Wish I would have seen this post. Was the rear spring a 6.3n?

    I know, you'd asked me for the tire codes... But for whatever reason, I cannot post on my iPhone any longer at Advrider. PITA. They are the newest models, got the white lettering yada yada...

    I don't let my bikes sit for very long normally, but they are abused mercilessly on whatever kind of trails and such. But for all intents and purposes, 90/10 fuel premium grade is what these bikes were built to run on, and there really appears to be no difference in performance running premium non ethanol. I've tried many times and all it got me was a premium price.

    One thing I’ve noticed on long dual sport type trips is better fuel economy with non-e. Non-ethanol seems to give me 5-8 more mpg on my 650 Husky and my 500. In the nasty single track, I never pay attention to mpg. After 30-60 miles I’m beat and ready for some cold beer!

    Hi all, New Fe350 owner here. Awesome bike. I ride lots of nasty, rocky single track and desert Enduro so I’m looking at protection for the bike. What do you all recommend? Are there any specific brands that work best with the Huskys?
    Thanks in advance. I’m looking forward to a long relationship with this bike!

    I've also observed improved fuel economy, not only in my motos, but also in my sports car and truck. Typically about 15% better MPG.

    15% is pretty high, but yes better economy makes sense as ethanol has a lower specific energy than pure gasoline. The difference though w/ 10% ethanol is only like a 4% drop from non-e.

    No kidding huh? Ok, might just have to try a comparison on that. Fuel mileage is really pretty crucial when you are always making "adventures" for yourself.
