How many miles are on your Sportie? How many miles since the stage 1 kit was installed? Sporties have loud valve trains. A lot of dealers will tell you that the engine needs a rebuild. If you are losing power, look at the brakes. You may have a collapsed flex hose or seized brake caliper.

 

Not true, it's an air cooled engine. If you aren't driving at all just sitting still, it can take five minutes to be at a normal operating temp. depending on the ambient temp. of the air.
Sorta compare it to a car with a radiator...it has a thermostat that opens and closes according to the temp of the engine. in freezing weather it takes a lot longer to warm up....remove the thermostat and you could drive for a half hour before it was at operating temp.

Sometimes in freezing weather your bike may never reach the normal operating temp.

 

I said if you ride it for ten miles, and you come back with sit at a stop light for ten minutes??? I've never in my life sat and idled a motorcycle for ten minutes. If it's going to be that long, I shut it down. More, riding it will generate more heat than idling. Your answer smacks of someone trying to be a know-it-all without proper information. I ride all year long, in Michigan (sub-zero temps fairly often, sub-freezing most of the winter), and have long-term experience with riding in the cold. I have NEVER failed to have my engine fully warmed-up within five or six miles of actual riding, but gave the longer number to admit the possibility gentler riding style and/or more stops. Even so, I stand by there being no excuse to not have your engine fully warmed up within ten miles.

 

Let's try an experiment then.
Do you have a thermometer dipstick? I'm not calling you a dipstick, just asking if you have one in your oiltank?
Go for a ride in subfreezing or sub-Z temps, without letting it idle before you ride and write down the temp of your engine at 5 miles, 10 miles, and 20 miles. Write down the temp. of the air also.
This summer when it is 85-90 degrees, do the same thing.

 

Yes, I do. I get to 190-200 in the winter (in the oil bag, which means it's around 215 in the engine) , and 220-240 in the summer.

 

Tek, my 2007 1200C is somewhat different than yours. If I ride to Fredericksburg, (36 Miles) on a 40 degree day my oil temp runs about 170 degrees, on a 100 degree day it runs about 205. Before I put the PCIII on it the temp would run a bout 220 on a hot day. I never saw 240 on it.

 

So, what do you consider normal operating temp.? What is cold, and what is hot?

 

Normal operating temp is 200-260 in the engine, or 180-240 in the bag. Cold is below that, hot is above that.

 

Tek, where did you get this info? Thanks

 

I got my operating temps off my dipstick, I got the normal range for the engine and oil bag from the service manager at Capitol Harley in Lansing.
