Interesting finds about oil air cooled engines!

Some of you may be aware of my recent 1216 rebuild on the 1200(1157) oil air cooled Bandit

I knew that it would run hotter, due to meat being taken out of the cylinder walls for 2mm over sized pistons, and put a temporary temp gauge on,until I under stood the cooling circuit for this particular setup, and change the oil cooler to suit the application.

Findings!!!!!

On my stock Bandit on the hi-way, 80*c  - city traffic in winter, about 92*c   About what you would expect.

1216 Bandit...... a lot different!  Winter conditions so far to date, anywhere between 95*-120*     Mild city to hi-way for those results.

So got me asking questions with dyno owners, engine builders, and last but not least, Dale Walker, from where I got the kit from.

All have said, yeah that's normal for oil air cooled engines, and don`t worry.

In fact, where I`m going to get my bike dynoed ( not for numbers, but proper tune) he runs Suzuki pro stock oil air cooled, and said his constantly run at 140*
and he also said that street going  Buels, can run at 160*-180*c,  so don`t worry, its just what they do.

Just had a good chin wag with Dale Walker, and said this is why I never, or recommend anyone running a temp gauge, cause people freak out, and he also said,  don`t worry about up grading the cooler, you can if you want, but not needed. Just run a good oil, and all is sweet

Wasn`t what I expected all these people say.

Great work that is good to know.

HaHa That's good because I've considered those gauges that go in the oil filler hole and others and concluded that I don't really want to know for the reason outlined above.

Sometimes ignorance is bliss.
