Hi Guys, I need a little advice if possible? 

Just purchased a Gas Gas tx270 on a 1998, had a bike when I was much younger and decided to give it another go now the children are a little older. 

I have drained the gearbox oil whilst engine was hot to refresh before heading out for first practice and replaced with 600ml of EP90 as a guy on here recommended. As the bike doesn’t appear to have anywhere to fill oil I removed the clutch plate and slowly poured in. Now I cannot see the oil in the viewing window and I’m unsure if there is too much, not enough as some other posts state only add around 400ml in. Just wondered if the bike needs to be run or left to settle before a reading can be seen? 

Any advice would be greatly appreciated as I know the consequences could be costly. 

Thanks 

The EP90 would create a lot of clutch drag. Best off using an ATF rated to Dexron III, 600ml is correct. The clutch case has "750ml" cast into it though 600ml was always sufficient.

Thanks guys, much appreciated
