could you post a pic of your xtrs on your foreman?
Check my 'Gallery' - just posted some.
Yes, I checked the speed with the speedo on my bike. I thought the same as you - Larger diameter tires should = more top speed, but that's not the results I have. I know because the guys I ride with have commented that it seems I have lost some top speed, as we have to do a little road riding to get to the trails (I'm always last to get there- ALWAYS). My brothers 1985 250TRX fourtrax SMOKES my bike on top speed, but it's all due to weight. I knew it was a slow bike when I bought it so I'm not too concerned.
I also noticed that it was working a little harder crossing the snow covered fields, but again, that should be expected. The lugs on those XTR's are massive. And it is still 100 times better than spinning the stockers at every touch of the throttle, especially after doing the carb spring mod. I couldn't keep my stockers from NOT spinning in the snow, lol...
But back to the original post - I know the XTR's are heavier than the regular mud-lites, so you might not experience any power loss issues. Think of the XTR's as being more like the 589's.
