Let me explain why you will gain some top end with the 26 inch tires over the stock 25 inch. The 26 inch change you gear ratio to a higher gearing, hence you will gain "some" top end speed. The weight has nothing to do with slowing the bike. Example, my buddy and I both have Grizzly's, we raced on stock tires, pretty much a even race and all depended on why had the holeshot. We both bought the same wheels and tires "589's" except he has 27's and I have 25's. I get the holeshot now everytime. I'm ahead low- midrange then with the 27's he comes buy me on the top end. Its all gear ratios and has nothing to do with weight.

 

Thanks for the info proEMTPFF i have heard that to about the clutch kits so i will hold off on putting one in till i have more info on them from someone who has put one in. I just bypassed the reverse rev limiter and it has proved to be useful in backing out of a few sticky situations. Atvoffroadextreme has a great site that showed how to override the limiter and now one just has to remember not to hit it full throttle in reverse because you WILL take off like a bat out of hell going backwards. I am now looking at overriding the differential rev limiter for better control in the mud if you know of anyone who has done this or how to do it please reply. I am glad you cleared that up on tire size increasing your top speed because i know it can really change your gear ratio if you change tire sizes to something a lot bigger or smaller.

 

The ratio will change even if you go up or down 1 inch in tire height. The tire doesn't have to be ALOT taller or smaller, just the more you go either way the more the ratio will change. Thank you for the info on Atvoffroadextreme.com, I may do the rev limiter thing. [img]i/expressions/face-icon-small-smile.gif[/img]

 

If this is tue why do I NOT READ A faster speed on my speedo you are telling me the added wieght does not slow me down?Then I guess there must be a problem somewhere 25" mudlites speed 106km 26"mudbugs 96km somthings wrong somwhere

 

there are many other factors that come into play also i think, the drivers weight, the true height of the tires because true height of the tires varys from brand to brand i have saw tires that were 26-9.5-12 and they were really only 25 and a half inchs tall. also air pressure in the tires will change the height and speed. i think the factors are to great on tires that are so close in size, I have saw 2x4 handa 400ex go from 22inch tires to 27 inch tires and the top speed was ridiculous, but they lost the low end get up and go. I hope this helped you out.

 

well not really my wieght did not change only the tires weight changed and know if you took the same tire weight but a different size tire it might be it should be faster top speed but more effort to get them going second of all you need a gps because changing the tire size is going to change the speedo reading but bigger tires on my grizz definantly does not make it go faster no way

 

Ok, let me try this one more time. You have 25 inch tires and a electronic speedo and then take 26 inch tires and the same speedo. The 25 inch tires will spin faster than the 26 inch sooooooo the 25's will SHOW "indicate" a faster speed on the speedo and sooooooo the 26's being that they will turn at a slower rate will indicate on the speedo a slower speed. BUT in fact because of the 26's changing the gear ratio you WILL have a FASTER top speed BUT lose some low end. I hope this will explain it.

gotcha thanks for your patients .So the only way to verify this would be with a radargun or gps I do not think the local police force would ablige me so I will get my buddies gps and check it out .I did the stock exhaust modification and got back some of my low end grunt.

 

it was great to have somebody explain that to me too, i knew i would get more top end i did not know if it would register on the speeeddometer or not, thanks for the info and explaining something that was a little misleading.

 

No problem guys, always happy to help if I can. [img]i/expressions/face-icon-small-happy.gif[/img]
