I have a 2021 reiju mr300 ,one finger clutch all day.I previously had a sherco and fitted a clake because of the ridiculous clutch pull. I would think the gasser and the reiju would have the same springs but might be worth a look .I do use auto trans fluid in my gear box .Type F as it has no friction modifiers .The reiju clutch is as light as the sherco was with the lake.I'm 64 and ride a lot of single track that requires a fair bit of clutch and I don't have any issues .Hands down the best clutch of any bike I have owned .Hope this helps
