i just put 25s on my wolverine...according to a calculater i found on the net, with the 58 stock top speed, it shoudl go 65 with the taller tires...what do you guys think? on the honda forum they are sayin a wolverine will never go 65

 

You will a little faster, but not 65, because you will run a little low on power and you wont be able to hit the same rpms in 5th gear with 25" tires that you did with 23" tires. You will be at about 59-60mph. Honda guys are mad because fully modded Ranchers can only slightly beat stock Wolverines...LOL. Take the baffle out of your pipe and put an airfilter in it. You will go faster.

 

is that all i need to do to turn those last few RPMS? baffels out and filter and rejet?

 

I hit 63-65 with the full exhaust and rejet with 25's

 

i just mentioned it to dad..he said we may get a full exhaust for my 16th birthday...in april.

 

That will definetly help you if its all stock right now. I was hitting low 60s like that, but it took awhile to get there. If you add a pipe and stuff it will help you get there faster, you wont go any faster, but then you can put the 23s back on and you keep the high top speed because it will rev higher and it will also get there faster. But definetly take the baffle out and open that airbox. Have fun

 

ok..so what is a better combo?? pipe/airbox mods with 25s or 23s?? i want most top speed

 

top speed go with 25's... but id go with the 23's.

 

i just bought my 25s for added ground clearence...they are dirt devils..maybe when these things are wore down i will buy some 23's, i want holeshots or razors..but no 23" rear tire size..plus i gotta replace rims

 

Its easier to explain it this way...

a) 23's stock - 58mph, average accel.
b) 25's stock - 59-60mph, takes awhile to get there, revs lower in 5th
c) 25's w/o baffle and filter - 62-63mph revs out to about the same rpm as stock
d) 25's with pipe, and intake mods - 63mph, better acceleration than"c" revs about as high as "c" but gets there a little faster.
e) 23s' good pipe, and intake mods - 63mph, revs highest and quickest

The reason that "d" doesnt go any faster than "e" is because, you are essentially in the same boat that you started with, reason being is that now with that pipe, redline is higher, but it still doesnt have quite enough power to pull to a higher speed than before (dyno sheet will prove this, top end power isnt increased as much as midrange) but it will accelerate there faster because the midrange is increased, but the top end isnt increased enough to pull it to a higher speed. With the 23's back on "e" you will be able to rev to the full potential of your mods, due to less mass and less of a load on the engine, you wont loose any speed.
