trapezeartist Posted January 18, 2019 Report Share Posted January 18, 2019 I picked my new-to-me Evo 250 yesterday and just spent a couple of hours in the garage with it. Unfortunately I won’t get out to play tomorrow as planned because the air filter was filthy and has to be washed and re-oiled. Then while continuing the general check over, I found the gearbox sprocket was sloppy on the splines. Is that to be expected? Quote Link to comment Share on other sites More sharing options...
lineaway Posted January 18, 2019 Report Share Posted January 18, 2019 I don`t recall mine as sloppy, but I have gone 10,9,10,11 and back to nine. So five sprockets on a 2016. It could also just be the brand. Quote Link to comment Share on other sites More sharing options...
the dabster Posted January 19, 2019 Report Share Posted January 19, 2019 I think it has the ability to 'float' transversely which helps keep it centred but if the sprocket can move through the direction of rotation whilst the shaft stays still then you possibly need a new sprocket, Quote Link to comment Share on other sites More sharing options...
lineaway Posted January 19, 2019 Report Share Posted January 19, 2019 Like a rod, side play is ok. Anything else not so good. Quote Link to comment Share on other sites More sharing options...
2stroke4stroke Posted January 19, 2019 Report Share Posted January 19, 2019 (edited) Dry the filter out on a radiator (or even use a hairdryer) and get out tomorrow! Let us know how it goes. Edited January 19, 2019 by 2stroke4stroke Quote Link to comment Share on other sites More sharing options...

Let us know how it goes. The filter is now dry, but looking pretty ratty so needs replacing. Anyway the bike is now in so many pieces that riding this weekend is not an option. I’ll take a more careful look at the splines on the output shaft this evening, hoping to find them all good. Then I’ll continue going through checking and cleaning everything, and hoping no other nasties crawl out of the woodwork. The dealer I bought it from is being good, so I’m confident he’ll provide a new air filter and sprocket. I just have to hope a sprocket change solves the problem.
