I bet that thing has a light switch power band. The modern 250s with power valves are much, much more linear in their power deliver. That said, they will still put you on your back quickly.

I would also like to gather the collectives views on the mods to proceed with next? And, wich one you prefer if so inclined.
USD
Oil cooler
Pumper carb
Battery relocation
Groceries

Or, something that needs to be done besides these.
Opinions? I know.

What are your plans for the bike? Does it spend lost of its time on the street or is dirt a regular part of its diet? If it is going to get dirty, what type of terrain? All of these will guide my advice.

Question How much does different tire sizes affect gearing?

I'm also going from stock 15/45 gearing to 14/45......I hope the bigger tire doesn't eat up all my gearing change and put me back at stock , that would kinda defeat the whole purpose of the sprocket change.....
Any feedback from you guys who have played with tire sizes would be great
Thanks in advance for any info

I would just compare how the bike feels before the gearing swap...then change front sprockets

lastly

not all tires are labeled or sized equally meaning a 110 maxxis might be the same size as a 130 t63 for example...

cheers
Good points Christian.....I definately noticed the Sedona and Pirelli are not near the same sizing wise, the Pirelli obviously runs MUCH bigger in sizing than the Sedona. I have no complaints whatsoever with the traction and performance of the Sedona 887IT, its been an awesome tire for the price so far. I just don't want to stick a way taller tire on the back thats going to offset the sprocket change I made......if thats going to be the case I'll take the Pirelli back and exchange it for another 120/90 thats going to be shorter.

Any more feedback from you guys would be great

For me, a mainly road rider with long highway commutes I would put them in order like this:

Groceries (if you mean a rack)
Oil Cooler (so you don't have to stop and let her cool down, or just to keep the oil healthy longer)
Battery relocation (it's easy to do and very cheap if done right- look up spud's write up)
Pumper carb (no need till you get the engine well past stock power with internal modifications)

I would also recommend (if your riding is like mine) a wind screen, heated grips, wider pegs and an NX650 5th. They all served me very well.

That looks like it's in a petaluma field

We all have mild to moderate ADD... what do you expect?! It's a damned wonder that we stay on topic as much as we do. Next thing you know, we'll be back on oil, tires or bikini pictures. I vote for the latter

Man that's sweet. Yes on the light switch. Once it got to the a certain point you'd better have a good grip on it or it'd leave you behind. I used to be fearless about climbing big hills with it. As they took off the over burden on these mines they pushed it over what was called a high wall. We would try to climb them and I looped the bike over on top of myself when I was 20 or 21 and dislocated my right shoulder. Still bothers me today. We usually wore helmets but it was work boots, jeans and tshirts for protective gear. Young and dumb having fun!
