I use 25-50 pensoil racing oil in my deluxe with very good results even on the hottest days. Its a little thicker than the rotalla 15w40. Some say to use straight 50W. I live in Canada so it is a LITTLE cooler here (no I don't live in an igloo). I like the heavier multigrades because they flow more easily when cold. I'm sure this helps to get into the triple gear bearings and rear cam bearing more easily on start-up. For gas I just run regular.

Pensoil racing and Shell Rotella oils are both higher in zinc. It's my understanding that this helps with friction with traditional tappet engines. These days zinc levels are getting lower and lower in motor oils because of increased use of roller rockers and tappets. High zinc is a good thing whatever you use.

Happy riding on your KJ!! I remeber that first time antisipation well! Mine lasted 24 years.

Thanks, John.

I also am concerned about the Gasoline used, and if since todays fuels lack the lubrication of Lead, do I need to mix anything with the fuel?
Usually, I would assume that a high octane premium fuel would be appropriate, but since the Henderson engine is more like a small car, does this apply?

I was thinking about Harley Davidson oil 20W50, but, I wasn't sure.

The motorcycle arrives today, so I am pretty excited.
This is a lifes dream come true for me.

I just want take things slow, and gather as much information as I can, Sort of the doctors credo,"First, do no harm" Before I even try to fire her up.

Hi Marty:
The recomendation I had heard of in the past has been Castrol #GP-4T 20W-50 mineral oil. I have not had a chance to try it yet in mine but I trust Castrol as a maker of good quality, high grade oils. You definately want a high viscosity grade oil rated for air cooled motorcycle engines as the henderson rear cylinders demand it. I have used a multi grade Olzium Harley Davidson oil with good results.

Hello, Fellow KJ enthusiasts.
I am about to take delivery of a 1931 Streamline Henderson KJ, and I would like to get some information on the fuel and oil/lubricants needed.

What octane fuel should I use, and what if any additives are needed? Also what grade oil should I use?

Any helpful hints for a new owner of one of these magnificent machines would be greatly appreciated.

Thanks!

Marty
