I have a 2019 1000, it has 450 miles on it. I have seen people on here and on the Facebook groups talk about how much power these things should have and being able to spin the tires and mine just doesn't seem like its there ever since it was new. It seems like a dog. I followed break in for the most part, and had the first valve adjustment before it was put away for winter. I have a full front and rear windshield and Before the winter max speed was about 66 mph which seemed low to others. Now over the winter I went to 29" tires (which I know doesn't help), 18g weights and B2 clocking. Max speed seemed to drop to mid 50's at 7K and it still seems to be a dog to me. I wish I had another one I could drive to see the difference. Air filter is freshly cleaned, belt didn't seem to be glazed or anything. Any ideas or am I just expecting to much?
Thanks
One thing is that these single TB v-twins are no where near as powerful as any with two such as the Can Ams, Kawasakis and such. And as such, they are acceptable to noticeable power reductions such as altitude..which will take about 3% for every 1000 feet, increases in load especially un-sprung rotational mass such as larger and heavier tires, and wind resistance which is greatly increased with windshields and such. Heck mine alone has about an 18% power loss from the altitude here...it will move 68/69 with no windshield but put it on and that drops to near 60...and it takes a long time to get there.
For yours I might consider all these factors but first make double-sure all is well with it...as in electrical power levels, fuel supply, air intake (Don't over-oil that Uni!), make sure those valves are correct and that she does have the proper compression, that the brakes are all releasing properly...ect. One other thing to consider is that with larger tires, the speedometer will be way off...will show slower so that needs re calibrated.
