Worth it power wise - yes. It's not just the added cc's, but more compression. The motor pulls harder at all rpms across the spectrum. It's not going to turn it into a 50hp MX king, but it's a nice solid bump.
I have not noticed that the gas mileage is much different. I did notice that the first few times out on the big bore my wrist was getting sore- I realized it was because I was having to modulate the throttle at a lower opening which made it sore.
Very easy install. I'm a rookie on motors and it was pretty easy on the LXR. In chassis.
The EFI adjusted with zero issues. I would say it starts far better than before- possibly due to the unshrouding of the valves in the bigger cylinder.
Pretty simple swap on the LXR; probably a little more teardown on the RX3.
