25000 miles later on the VT1100 experiment
Written by mlmiller1959 on 9/29/2010 at 09:55 pm

I guess the advantage is that we know it works and have expanded options for
parts.

Anton,
I sure don't see any advantage. My bike consistantly averages about 45 mpg (43
to 48 and as high as 54) weather in the mountain twisties or on the eway from
60 to 85mph and I didn't lose any performance because of the lower diff ratio
with no extra work. The engine does not have any problems running the stock rpm
all the way up to 75k. Just look at the results Leland has had with all his
bikes.
Fred

I've now had the thing 3 years and put just shy of 30000 miles on it. As the first person to do the VT1100 final drive swap, (and that I haven't checked in here for a while...) I thought I'd give an update. First of all, it's the same old

        Mark, Show me an advantage for all the work and the loss will be the loss in performance and/or the possable problem of clutch failure. Fred --- In

      Well, my PC is faster in a straight line than just about any other I've run across, (excepting some of the more 'modded' bikes on this list) and gets the same mileage or better than a stock one. It was worth it for me to do the swap, plus I l

    Anton, I made this swap because of your previous work. Thank you for your efforts, as I didn't have that thought on my radar screen. I have found this mod to be very worthwhile. Here is what I found: 1. RPM is down in every gear

      Anton, I forgot to add this. When your engine goes (hopefully not too soon, consider swapping out the engine for the VT1100 engine. I have been studying this and thing it may be possible to do this. That said, it's always the the last 5%

    Got 18,000 now on my VT1100 rear. Something about hitting 60 mph to find - another gear! Holy Smokes, Batman! Priceless! The reduced rpm at high speeds makes the PC800 into quite a little interstate eater. At lower speeds I honestly don't fee

      Dave, Just curious on the cost of the conversion. I got my final drive for $29 + shipping. So even though the mileage is modest, it helps offset the cost. If you told me I could spend about $40 to achieve a more relaxed bike at highwa

        If I could find a VT rear drive cheap I would do it just for the heck of it. My bike revving at five to six grand on the highway doesn't bother me or the bike the least. With ear plugs I can't hear it anyway. My new DR 650 doesn't have a tach

        Jerry - Yeah, the hitch in the VT1100 conversion is you gotta find a rear end, and only the rear from '87 to '92 (As I recall, at least) will fit. I found mine on Ebay after searching for 3 months, and got it for $85. I had my mechanic instal

          Dave, I found and bought a '90 final drive from a VT1100 and will ask Honda service to install it next time I change rear tires. Thanks for the heads up on the year requirement. Would you let me know if you needed anything else besides the Fi

            Nancy, sounds like a pretty good deal you got there. The new one should just bolt right up! There is a seal in there somewhere that my mechanic just re-used. Of course you'll put new lube and spline grease in, but nothing else in my case! And

            Nancy, The black plastic dust shield is different. I thing there are 3 bolts holding it on, a simple swap out using your PC dust shield vs. the VT1100. I think you can use the vt1100 as is, but the vt dust shield does not match up to the
