I come from a cycling background where ceramic bearings are a proven technology. Anyone know a way to sneak them into my Justy?
I put big fat wheels on her, and I knew it would wear out the bearings- so here I am. I figure it's worth looking on the board to see if anyone has any insight.
Ecomodder website says synthetic grease will also help with MPGs, we will see.
The rule in cycling is obvious: less rolling resistance = less work. Obviously I want all that 1.2L of power moving this thing forward as efficiently as possible.

I had thought about this at one point, my only concern was with the shock to the bearing when I hit a pothole at high speeds. Worried I'd render the bearing useless..

Good point. That's probably less of a concern to the F1 types who employ them regularly.
still, they are used in mountain biking extensively, I wonder if they use them in MX?

In case you were wondering:
Rear inner and front: 30mm inner diameter, 62mm outer diameter
rear outer: 25mm inner diameter, 62mm outer diameter
From what I am researching, they are at least $110/each. On a small engine like ours, the payoffs would be huge, but I am not sure $600 huge. I was hoping to find something for trailers or snowmobiles.

Yea I don't know if they'd be worth that much, but I bet they sure would be very nice to have!

the rolling resistance of a single row ball bearing vs the ceramic bearing is going to be useless compared to the cost. i did both sides, front inner and outter bearing for about 35 bucks total. think of the pay back period on that. also youd get a quicker pay back and probably more, by jsut removing all the crap in the back seat that you casually leave there.
