MC 21 Stock Jetting and Mountains ??

Just purchased a 1992 SE and was wondering about running too rich over mountain passes in British Columbia Canada. My ride is from sea level to approx. 5000 ft. I don't want to bog down and have to coast home. Any one out there ride in the mountains? Cheers.

Not really, the hills in England mostly can't be ridden over!

As for the jetting, I'd personally be more worried about siezure, and keep the thing jetted for the leanest conditions you expect to encounter. Running a little rich never killed a motor, running lean has and always will... Crying or Very sad
