Airbox versus Pods

[KEITH KRAUSE]

That pic of Bruce beating that V-Rod is one of my all time favorites here.
I just KNOW that guy was ticked off behind those dark glasses.
Bruce won. Period.

Been on this board for almost 2 years, and honestly for every 1 poistive "podded" carb post, I read 10 horrorific, regretfull posts.........

Heres a post a while back:

Jetting isn't understood by many. Many even think you just pop in a new main jet and you're done.
Then there's the variables involved with each bike. Then you need to actually do the job and prepare/adjust the carbs... and the rest of the bike, before you re-jet.
Easy to see why so many people have trouble. Lack of knowledge, short cuts taken on preparation, etc. Great recipe for frustration.

True. If it was easy, there'd be no need for this forum. The performance gurus would be out of business too. But if you persevere, the rewards are very satisfying.

To go with pods you have to be willing to pull the carbs as many times as it takes to get things right. But since you have pods the job is pretty simple. As Keith said you have to have some understanding of what you're doing.

There have been a few posts about the newer bikes and retaining the stock airbox. The biggest reason is they are all ramcharged these days. Snouts in the fairing feed the airbox with all the air the bike could ever use.

renobruce love the pic and video . I does appear that your bike was bouncing more that the Hog was. Do you think that is suspension related or how it was tied down? Maybe the operator of the Dyno favors Harleys?

Was the end of the video cut off where you looked over to your oponent and said:

"And....I OWN it!! :razz: "
or
Not bad for a 21 year old bike eh? :-k "

I was picky about how they tied my bike down. And the way they had the straps set up was kind of funky.... I guess more inclined for Harleys. Fatkid89704 (Steve) was watching and said my back tire was hopping and smoking through the first three gears. Yeah, the operator did favor Harleys.... this was at Street Vibrations, the 5th largest Harley gathering in the U.S. The guy on the VRod was actually a pretty nice guy. I had met him a few days earlier. But yes, he quit bragging about his modified bike after I beat him. He claimed he had 30K in his bike. Mine is all stock and I bought it new for 4,450.00 :mrgreen:

On the subject of intake restriction. Only one cylinder is drawing air at any one time. If you have a large pannel filter, with more aera than any ONE pod filter, you should see less restriction, and therefore more power.

the pannel filters on modern bikes are HUGE.

I agree, although at higher rpm, the combination of the air demand from four cylinders is great. In my opinion, larger low restriction filter area in a box with generous dimensions that utilises velocity stacks is the answer.
This thread has thrown up some controversial and also, much sound reasoning.

Bruce, thanks for sharing your experience and video.
I haven't encountered a dyno drag setup down here. How do they guarantee that the roller resistance/friction is identical for both lanes? This is crutial if the results are to be accepted as accurate. If there's any variance, one lane would reqiure more HP/greater traction to compete. A more valid test would be if the bikes did a second run on the opposite lane and added the two times for an average. They do this for land speed record attempts, by completing one run in each direction within a one hour time frame. The reasoning is that if you ran in only one direction, there can be some down hill/tail wind asssitance. I think the timeframe is short to try and replicate conditions for both runs.
Do these drag setups provide fanned air over the bikes, or do you just hammer them for 10-12 seconds and let them air cool between runs?
I presume the 1/4 mile is measured and timed electronically by counting the revolutions of the driven roller. Is there a theortical wind resistance factor built into the electronic timing, ie could you compare a dyno drag time as an accurate comparison to a conventional drag time?

Speaking of pods, anyone know a good place online to buy a set of K&N pods for our GS's?

I'll trade you a set for the stock GS1000 airbox ;-)
