For those who have changed gear ratio

I see several of you have changed to Euro Gears, or changed a pulley or 2.

Of those that have, did you notice any change in MPG?
Positive or Negative.

I would think it would have a positive effect on at least highway MPG.

Thanks.

Dad, I know this does not answer your question, but I recently put on a 33 tooth front pulley, then weather became unfriendly, so no test on mileage. Though I did notice that 1st, 2nd and 3rd gears were all held longer.

And by the way, how are the Exedra Max 's holding up for you?

i put on an aftermarket rear pulley and dont care about gas mileage but the gears are alot longer and 1st is actually a useful gear

Did the same with the front, and same drive results.

(stupid sarge probably got the last rear pulley being sold on this planet)

Thanks guys, but I wasn't really asking about the driveability.
I've read about that numerous times.

Just the MPG.

The Excedra Max's seem to be so so.

I've got about 4K on them and they look rough. I don't expect to get any more than any other. Maybe less. We'll see in the spring.
Don't ride much for the next 3 months.

I'll probably get another rear to match the front when it goes, but after that, I may go back to the Cobra's. They are more expensive, but I like the way they feel better and they did last the longest.

I did euro gears & a 225/60 16 ct. No difference in mileage. Avarage 40 mpg. But my speedo is finally accurate.

I did both, in stages. Couple months ago, I put a 33 tooth pulley on Belle. The performance is as you read, the MPG was roughly the same. Then a couple weeks ago, I installed the euro gears. Again, performance you have read about. MPG? Unknown yet. The tank came off, so I lost the trip numbers, and then the Rostra went on, again losing the trip numbers. I think it may be *slightly* better, but that is mathematically induced. Before the changes, I would ride 100 miles, the odo would read 110, so MPG would be high. Now 100=100, so it would fall off some. This is balanced by the engine working less, and being more efficient.

Agree on Excedra's. I have about 1k miles on mine and already see the wear on the rear. Darkside is next.

The rostra is on and working. Not smooth at all, surges real bad at low speed, with magnets. It may need a longer actuator arm, I am not sure. Posted for "wiring help", but it apparently isn't common enough for much to be out there.

Rubber side down.
