engine heat
I posted a concern regarding the heat coming off a somewhat new to me '97 Baddoy awhile back. I got a '93 fxr and a '89 Softail, both with engine mods done by the PO, both run about 175degrees via the thermometer oil dipstick. On the Badboy, cam and head work done by PO plus thunder headers and S&S carb and air filter, the dipstick reads 225degrees after a 30 mile run on a cool day (maybe 70 degree weather). Should I be concerned? Would switching to a syntheitc oil drop that temp? 20k miles on bike, spark plug color looks good. Thanks.

You mentioned head work. Have the heads or cyls been powder coated. I had my cyls powder coated.. They got so hot that took them off. I bought new ones and sold the powder coated ones to a custom bike builder.

Running way hot is not generally one of the more common problem with Evos like it is with twinkies... unless perhaps you are running way lean. Running too lean will heat up any engine, pleasing the EPA, but not a good thing for the engine, or your thighs.

My Twinkie bagger runs about 200 degrees in 85-90 degree weather. I have an oil cooler,however,thats running with lowers-and its got a cam with the 95 kit! Something isn't sounding right-I would be very concerned!
