Don’t think I’ve replaced a gasket for 4 or 5 years by oiling/ greasing on assembly 

Going back to my theory about maybe we change the oil & especially too often (as a Clubman rider) - just done a Coast to Coast trail ride (on a XR 400 I may add)

There was a chap on a 4Ride and he's done 478 miles over 2 days and ridden at speeds of up to 60 mph

He didn't change the oil and/or filter in those 478 miles and I guess the motor was working a lot harder than 3x12 sections at a Club trial with a Clubman pootlng around 

 

Made me think we over service them perhaps

I  think trials conditions are probably worse than a 500 mile trail ride as engine is hot and cold and working at lower rpm/ higher loads etc.

But yes I think the 4rt manual and service spec is based on motocross conditions and not trials.

6 weeks oil and filter every other has worked for me over the last 10 yrs.

Also added with a bit of common sense - probably ride all summer in club trials and change less  often. 

A flat out S3 round or wet national and will do more often

 I know a rider that only changes the oil and filter once a year. He rides one event a month. Just depends how long you want to keep the bike. I prefer the change it too much approach.
