Willie --

What makes you think they always check the front cylinder?

(Could be a reason for that vibration!)

I reviewed every option relating to an oil tank and the best design option seems to be inside the rear hoop in front of the tire. No one makes anything that looks like it will work so I will have to make it myself. I don't want use aluminum in the an area that I could run over something on the course and possibly hole the tank near the rear tire. I had some 10 gauge sheet steel that is a little heavy but the weight will go in the right area and it is tough. I fab'd up a cardboard template and filled it with styrofoam peanuts to determine volume. Approximately 4 quarts which is more then enough for an XL engine.

I allowed for an inch and a half of clearance from the tire in full forward position. There is an additional 2 inchs of chain adjustment available aft.

The oil tank will be solid mounted. The oil tank on the XB is half the gas/oil tank and it was mounted solid without any issues. I am more concerned about the battery. I will rubber mount the battery using Harley isolators ...

The motor on the XB was probably rubber mounted as to where this one will not be..........I broke a lot of parts this year.

..... In addition, vibration at speed will froth the oil in the tank.

Or will it help the air bubbles get to the top

Little bubbles have quite the uphill fight to get through 50w... :|
Either way, keep at it, only 268 working days to Bonneville.... leaving you with pack and travel time for inspection... 8-)

The neck insert is complete ... I had to draw it in using 3/4 all thread and a breaker bar ... It was made in 2 pieces. Top half and bottom half.

The bottom half was made flush and the top half is about an inch proud to get the front end as low as possible. The frame was made for a car tire and with a bike tire the rear is already low.

the rear of the frame is 3" off the deck ant the front of the frame is about 3/4" higher. Once the engine weight and rider weight are added it will come down some but I will have to add straps or cut the springs to level it out.
