Maintenence Intervals FE390?

I am looking at buying a FE390. What are the service intervals like for the valves for a casual trail rider - are they easy to check? Is the bike easy to live with?

Is there a manual on this site?


Thanx in advance

Thanks for the link, but it doesn't show the 2010 FE390. The manual for the other models shows piston replacement every 90 hrs (thats every 10 rides) - wow.

Does anyone have the 2010 FE390 manual? And have experience on maintenance.

Thanks

Don't have the 2010 manual or any personal experience, but I did ask a UK dealer and they said nobody replaces the piston (and various bearings) just because the bike has done a set number of hours despite what it says in the manual. They said they'd expect to get at least 150 hours before changing those parts (still not a lot admittedly) but in practice they would only change them when you start to get problems such as a bearing rumbling, and that could be a long time if it's well treated. Hopefully someone who's got a 390 can tell you how far they actually got on the original piston...

Of course, depending on where you are and what warranty you get you may take a different view if you think that not following the guidelines is going to void your warranty for anything that goes wrong in the engine. Not much chance of needing to worry about that in the UK though, unless you're planning to do more than 90hrs within the 30-day warranty period.

Member Dustbite runs a tour company down in Portugal and uses the 450 and 570's. He got about 500 hours out of his bikes before having to re ring his bikes, of which he has 4, two 450's and two570's. One 450 needed a cylinder. He's still riding them on the original lower ends and heads and valves.

Follow the maint schedule in your owners manual as far as oil changes, valve adjustments, and keep the air cleaner, clean.

Go ride.

The manual says check Valves on 2010 FE390, FE450, FE570 after first 3 Hours then every 15 Hours.
The dealer checked mine after 3 Hours, said they did not need adjusting. Havn't had them check since and has 20 Hours on it.
Never had a ride on the 390 but the 570 is real easy to live with!!! Crack the throttle open and it goes like the wind, or just chug up a steep rocky hill slow, it does it all. No need to even change the sprockets.

Re: Maintenence Intervals FE390?

Valve lash is easy just remove fuel tank and unbutton radiators ( mounting bolts only leave the hoses connected ) loosen 4 bolts on the cover and you're away. There are markings on the head and cam that will give you tdc and there is even a provision for locking the crank at tdc. It's a two beer job.

Re: Maintenence Intervals FE390?

I checked my valved at 3 hours=no problem

checked them again at 40 hours= slight increase in lash to max limit

checked again at 70 or 80 hours, = one exhaust .0005", yes 5/10,000 too loose, had them reset to minimum.

The intakes have not moved since the first 3 hours.

Dustbites bikes with 500 hours needed only to "replace" the exhaust shims, as they distorted slightly.

Others have reported in the hundreds of hours without valve adjustment needed.

To me this further proves that the fine dust that get's into the fuel via the vent tubes on carbbed bikes is the main cluprit for valve wear.

The snow bike conversions of regular carbbed bikes have also reported hundreds of hours of operation without valve adjustment as well.

That is impressive what sort of oil does he use? I know a mechanic/honda lover who is now blaming breathers for their short valve life.
