hello everyone .
in india , RE is a cult bike as well as a Tourer .
i am in to long distance continuous riding, (400km at a stretch , easy rider(500miles/12hrs) saddle sore 1000 miles in 24 hrs ..... that too in india ..!!!.)
i also tour a lot with a pilon + two saddle bags and bike gets really hot .
230+deg F is measured at the sight glass regularly .
Lot of oil is consumed especially at long distence rides.(upto 1.9 lit in one saddle sore 1650km/22 hrs)
i tried
RE liquid gun(20 w 50 mineral ),
motul 3100(mineral),
motul 5100(20w50 semi syn),
motul 7100(20w50 syn),
amsoil V twin 15w 50 fully syn)
Amsoil 10 W 60 (fully synthetic)
Oil consumption is much lesser in Amsoil oils but still alarming .
350 and 500 both have same surface area , ridden at almost same road speed and rpm . but 500 produces @40% more torque/power and hence heat .
adding a oil cooler will add more quantity so repeatability of the oil will reduce life will increase , and cooler oil will help keep the engine hover around 210 220 deg F ..and control excessive thermal expansions , and arrest oil consumption ..
the engine needs serious cooling .
at least in india.
