jsp Posted April 29, 2016 Report Share Posted April 29, 2016 How much gearbox oil should I put in my 2013 bike, it has had the 2014 mods done, ie the breather near the front sprocket has been blocked and a new breather fitted round the back of the engine near the kickstart Quote Link to comment Share on other sites More sharing options...

canada280i Posted April 30, 2016 Report Share Posted April 30, 2016 Manual says 450ml but I run my 2013 on 400 with no issues Quote Link to comment Share on other sites More sharing options...
tsiklonaut Posted April 30, 2016 Report Share Posted April 30, 2016 And going a bit over isn't an issue either. I've run a bit over 500 ml without any bubbling at all, meaning it is still below crankshaft. Oil properties last longer in larger amounts, that is why OSSA changed ther official spec from 350 to 450 ml for the same engine, but also were concerned with extra weight. Hence you can go a bit even more if you aren't concerned with 100-200 grams of extra weight on bike lol. Quote Link to comment Share on other sites More sharing options...
jsp Posted April 30, 2016 Author Report Share Posted April 30, 2016 Gone for in the middle and put 450ml in, I was also going to change the Coolant but I can't get the bleed screw out its rounded off the head Any suggestions ? Quote Link to comment Share on other sites More sharing options...
tcrhino Posted April 30, 2016 Report Share Posted April 30, 2016 ... but I can't get the bleed screw out its rounded off the head Any suggestions ? Apply heat to the bolt and the surrounding aluminium (be careful with the painted pump cover...) and use a tight fitting torx bit, drive it in the allen head of the bolt and loosen.... Another option is to dremel a slot in the bolt head and to use a screwdriver. This is a bit more difficult because it is a small bolt. Btw. I am using 450 ml. Motul Textron III (2015 engine).

jsp Posted May 3, 2016 Author Report Share Posted May 3, 2016 I was on GRO but I bought some Putolene nano so I put that in and the gear change felt better Quote Link to comment Share on other sites More sharing options...
tcrhino Posted May 3, 2016 Report Share Posted May 3, 2016 I was on GRO but I bought some Putolene nano so I put that in and the gear change felt better Though my dealer advises to use Dextron III (Motul) I am considering to use a dedicated gear oil like Putoline Nano. How did the change to Putoline affect the clutch? More or less dragging and did the clutch feel different? Quote Link to comment Share on other sites More sharing options...
jsp Posted May 8, 2016 Author Report Share Posted May 8, 2016 (edited) The clutch drag seems to be better with the nano and the The gear change seems crisper with the nano, I must admit Due to a lack of riding I bet it's nearly a year since I changed it so Maybe any fresh oil may have seemed better. I've found the nano On a website cheap so I may purchase some more but it it is a top End product. Does anyone run on PJ1 ???
