Lefebvre Posted September 19, 2018 Report Share Posted September 19, 2018 What is the recommended oil change for a 2018 Beta Evo 200? Is every 15 hours OK or even 20 hours if strictly riding at moderate speed? Thanks Quote Link to comment Share on other sites More sharing options...
mel parkin Posted September 19, 2018 Report Share Posted September 19, 2018 change every 8hrs/or two trials. use good quality light oil [motul] & experience smooth gear change & no clutch drag. Had a 2017/2018/2019 arriving Friday great bikes,just need a little extra care. Quote Link to comment Share on other sites More sharing options...
tshock250 Posted September 19, 2018 Report Share Posted September 19, 2018 Changed oil every 5 trials using nanotrans, no probs, worked perfect. Quote Link to comment Share on other sites More sharing options...
jamo_duval Posted September 20, 2018 Report Share Posted September 20, 2018 What Motul oil are you using Mel? Quote Link to comment Share on other sites More sharing options...
dan williams Posted September 28, 2018 Report Share Posted September 28, 2018 Maybe once a year. Modern synthetics can go 20,000 miles when used as an engine oil. They're hardly challenged in the transmission of a trials bike. The main concern is water from condensation causing the oil to emulsify. If you ride once a week that's enough to keep a film of oil on everything. Quote Link to comment Share on other sites More sharing options...

On the whole I'm inclined to go with Dan's version of events, for exactly the reasons he has already given. There must be an awful lot of perfectly serviceable (and expensive) oil being poured away.

lineaway Posted September 28, 2018 Report Share Posted September 28, 2018 ATF, change often. It is cheap who cares. Why, the clutch works best this way. I don`t care what oil it is, but if you ride often change often as it will tell you what is going on in the bike. Quote Link to comment Share on other sites More sharing options...
heffergm Posted September 28, 2018 Report Share Posted September 28, 2018 I can't recall if Beta drain/fill plugs have magnets on them. The ones on my GG do... after ~8 hours or so, they're basically covered with clutch debris. I do 8 hour changes... Quote Link to comment Share on other sites More sharing options...
dan williams Posted September 28, 2018 Report Share Posted September 28, 2018 Not clutch. That’s your Gas Gas Gear Gears grinding off. ? Quote Link to comment Share on other sites More sharing options...

dan williams Posted September 29, 2018 Report Share Posted September 29, 2018 (edited) Betas do have magnetic plugs. The majority of wear on the gears happens as the gearbox breaks in and the gears wear into each other. There’s always going to be some residual particles from that early process in the box since there’s no forced oil flow and lots of nooks and crannies for particles to settle in and the box is never completely purged of residual oil. The tiny metal particles in suspension don’t really cause issues with the gearbox as they are only as hard as the steel of the gears and are coated in oil. Sand or silt from getting dirty water in the gearbox is another matter. Then an immediate change of oil is called for as you now have an abrasive in your gearbox that will wear bearings and the sliding surfaces of the shifter mechanism and other things that can be bound up by sludge. The water itself usually won’t do much as it will settle out of the oil and sit in the bottom of the case. That’s why it’s so hard to clear out milky oil when water gets in. You usually have to run the gearbox to emulsify the oil and change it several times to get most of the water out. Not a problem when the oil is used for engine lubrication as the water will evaporate out. What wears oil in that case is heat and contamination with fuel. I forget where I was going with this?
