Do you feel that riding a big inch/high torque bike requires you to ride differently that you do on a less powerful bike, or when this bike made less power?

I don't mean like being careful with the throttle in traffic, I mean like keeping it in 2nd and letting it spin rather than shifting 3rd and it being difficult to keep a steady speed...

Any input?

What about gearing? When you got big inches/high torque did you go back to stock gearing or leave it geared down (like a 30 tooth front pulley)? And why or why not?

My 124 has stock gearing.  The main difference is catching up to cars a lot quicker than you think so you need to leave some extra room/back off the throttle earlier.  The cams in mine are the TMan .625 which are a low/midrange cam producing 125 ft lbs @ 2500 RPM.  The motor pulls hard from 2000 RPM so no, I don't leave it in a lower gear.

Like trying to hold 20 mph in slow traffic. From off-idle to 2000 rpm the torque is ramping up so hard it makes the bike 'abrupt' as hell. If I put it in 2nd the throttle is like a switch... on/off... I find it easier to control if I leave it in 1st and let it spin some, gotta keep it out of that range where the big ramp-up is.

It's actually a little better now because the new cams took the edge off the low end a bit. Used to make 106 @ 2200, now it doesn't make 100 until 2300... made it a tad easier to hold a steady slow speed, but it's still abrupt.

It blows my mind that you're using .625 lift cams.... My little .484 lift must sound like a joke.

You can not go slow.....not saying that because it is fast, but to go slow you use the clutch way too much but it is either 3000 in one gear or bucking in the higher one

Leave more room for the vehicle in front of you or don't ride where you have to go slow

Exactly! I just wondered if other people were having the same experience. I'm geared down 7% (from 33 to 31 teeth) and I was  thinking about going back to stock gearing... but my little voice is telling me that's a bad idea. It's good as long as I keep the rpms over 2200.

I've found my S&S 113 revs quicker than my new 103. It's up to the rev limiter before I know it.
Different builds altogether, the 113 is all about HP, and the 103 is about torque. Two different rides.
My little 93" also revs quick (light wheels), and I have to be careful (no rev limiter!)

The 103 makes more torque than the 113?

[HOGMIKE]

The 103 makes more torque than the 113?

not even close, but the 103 is first to 100 ft lbs.
After 2200 rpms the 113 keeps climbing.

A 131 inch will eat more gas then both and if it's built by JIP'S, (for lack of better word) it will 'blow up' in less then 2000 miles... 'Blow Up' is a bit of exaggeration but just a statement of what will happen if you dont adress their 'fine workmanship' in engine building within 2000 miles.. In other words 'expect' to rebuild a JIP'S Motor about the time you get your first nut off with that monster.. And that's the only guarantee JIP'S will give ya..     WHEN YOU GO THREE TIMES AROUND THE BLOCK WITH THESE GUYS.. then you provide word of mouth on how much they suck !!! But, if you dont mind spending $8,000K Plus for a bullet proof block,, go for it... 

[Half_Crazy]

So what eventually happened? Was the third time the charm?

[Rooster]

Curious to hear the whole story Cvobiker. I made it to 8k with my 131 the first time now just under 2k and seems to be much better the rebuild was on their dime it just took a few months to get it back. And my gas mileage is in the 30's but got down to 20's a few hundred miles before it blew.

[Half_Crazy]

now just under 2k and seems to be much better

So what's it like to live with the 131 on a normal day? Do you have numbers on what it puts out?

I swear, the more time I spend with my bike the more I realize how ridiculous this thing is. I really didn't need this much power. I mean, it's a blast and all, but most of the time riding the thing is an excercise in self control.

Lotta' good comments on this subject, but hogasms last remark is my sentiment,
exactly.  I don't know about anybody else's Motor, by mine gets HOT when it can't breathe.  Heat is the enemy.  Put 'em in the breeze and turn 'em loose!  WFO 'till she gives up the ghost.  You'll never hear me complain that my Motor came apart after x amount of miles.  I know when I modify my Motor, I'm on my own.  I built it to go fast, and that's what I do.  The thrill has always outweighed the risk for me.  Later--HUBBARD

I've got the Jim's...err Jips in my 09 RG. It's a blast to ride, but, it just does not want to just cruise. It's only happy at WOT. It's just not designed for a Sunday afternoon cruise to the park.
