Well there are thousands out there with no issue but in 07 and 08 the had a tapered rod end with a bushing and in 09 they did away with the bushing so its my opinion that if you have an 07-08 id address the crank especially if your doing heads and TB. No chicken little here. My motor had 118k on it when this happened and I was advised to do the crank before I did the 107 anyways. Your best bet is to check your crank runout and go from their.


Sorry for the hijack OP.

 

I am getting too old for wheelie videos, I prefer to scare the crap out of myself when I do wheelies!

The cams made a significant change in acceleration and power. Wait until the 30T gets done!

 

I would agree that it has a lot to do with the tune. I don't have much done to my bike other than cosmetics and a stage one (minor details in sig) but I did have it tuned professionally he took about 3-4 hours to do it and on the dyno the numbers were great and the butt dyno liked it as well. With the right tuner and the skills from the tuner himself it makes a huge diff. Get a rookie and I willing to bet it could be worse than before.

 

Not a single person has blamed the rider.

if you're getting beat by someone else on a multiple bikes, especially once that is on paper more powerful than yours, YOU are doing it wrong.

edit:: wait

Are you saying you beat him on your bike and he beat you while riding your bike when you were on his?

I had to re-read this a few times. I think that's what you're saying

 

You caught yourself before I could correct you.................Thats what he said.

 

Yeah, we eliminated the fact it could be the rider when we switched bikes. I'm thinking it has got to be tune related. I understand the tune has a lot to do with the overall performance. I'll have to have a word with him about it... or maybe I won't... j/k
I will probably go with a bigger cam than the 255's or 222's and do pulleys at the same time. Might as well right??

 

All the engine mods you can do will be a waste without a good tune.

Also, the SE-255 is a good stump pulling cam, but it's not a good cam above 4,000, expecially hard accelleration or running your bike against another bike. It doesn't do worth a **** in a drag race.

Lots of better cam choices out there than the SE-255.

Honestly the biggest perfomance inprovement you could do is get rid of those slip-ons and get a good 2-1 system....night & day difference.

 

Don't over-cam your bike....results will be negative. If you're going to keep stock heads & compression, the 222 is a great cam and a LOT more performance on the street than the SE-255. Bigger isn't always better when talking cams unless you have other mods such as higher compression & heads to support the cams.

Don't get caught up on peak numbers either....it's all about where & how the cam makes it's power & torque. Look at the rpm ranges for gains & look at the curves. The Wood TW-222 is 2,000-6,000 & is a great all around cam, which is why I chose it.

 

Great info, thanks! Yeah a pipe is on the list before the cams, which will be a close second. So that 222 is pretty different than the 255's I take it. I always sort of thought they were about the same...

 

My stock 96" S&S evo on my old bike put my stock 103 to shame!
