Right. Doesn't break down from heat or get as dirty, lasts twice as long or 3x conventional. K&N oil filter works better too. I use Royal Purple for motorcycle, helps clutch. I go 5k miles between changes @ 1× per year. I put magnetic plugs in last time, anxious to see them - next month! Run about 8k per year. 27000 & counting.I changed my bike over to synthetic oil this season and it is running much cooler than last year. My temp. gauge was always 1 bar above the middle, but now it rarely goes above the middle bar. It's got to be good if the temp has gone down that much.
I've been using synthetic oil for the last 15K (Castrol Power RS), also using the K&N filter. Yes I feel it is a little bit cooler and smoother. But the oil still gets nasty. According to the manual the oil has to be changed every 7.5K, I feel it is too much. I'm changing mine every 5K, at that point shifting gears gets clunky. Last time I rode 5K in 6 weeks, mostly highway doing 70-85 MPH. The oil got really dark, maybe because most of the time I was at +3000 RPMs in 6th gear, I don't know.Right.

Doesn't the thermostat control the engine temperature?
The "thermostat" controls coolant flow thru the cooling system, that is all it does. It does not control any operation of the fan.No the thermostat controls the fan switching on and off. With synthetic oil you have less heat so therefore the fan just doesn't have to switch on or off as much. The bike runs cooler always.
By the time an engine reaches normal operating temperature the thermostat is usually fully opened up. On sportbikes with digital engine temp displays we usually see a 4-6dg drop in coolant temps when switching from non-syn oil to synthetic oil. But that doesn't bring coolant temp down enuff for the thermostat to close.But if the engine is running cooler, will the thermostat just close and bring the coolant temperature back up to the thermostat rating? Should have no bearing on oil temperature as oil can take a while to warm up whereas the coolant temperature can climb quite quickly to thermostat opening temperature as I am sure your gauge will prove out.
The coolant temperature is what shows on the gauge.
YEP...if the oil is adding to a reduced engine operating temp then the fan will operate less and sometimes for shorter periods of time during operation.True sfair. but the time between fan cycles should be a bit longer because the rate of heat generation due to friction is lower.
Heat due to combustion is the same.
Bottom end bearing surface temps should be lower too independently of top end temp and coolant temp.
which fuel controller is your custom map for?Pinging is NEVER EVER good for an engine and if it is due to advanced ignition timing then the timing IS TOO FAR ADVANCED. PERIOD. Been hearing this occurrence of pinging for quite some time (from the beginning if I remember correctly) about that flash.
My throttle mod along with my custom mapping on my dyno for my Vaq accomplished many things. Careful tuning of all parameters netted me good power and torque (the last dyno session was at 95,000 miles, it made 88 H.P. and 108 pnds tork), a cooler running engine AND 45 to 51 MPG. Just b4 I retired that Vaq I came up with my Gen2 throttle mod which just about equaled the flash.
ON 87 OCTANE.....with NEVER a ping.
I had a PCV on the skoot. I had made quite a few custom maps during my time with that skoot as I never stopped playin with it. That last remap session at 95,000 miles was to accommodate a plenum intake I had designed and madewhich fuel controller is your custom map for?
