Just to clear a few things things up Welard, the pod threads you refer to, use stock carbs, Tweakins bike, Rons bike {MC rider} and CRF's bike all run different carbs. Honda designed its induction system as a whole, the stock keihins really don't work well with pods, anyone that tells you otherwise has probably never ridden a well tuned Honda/4. CR's/RS's are a race carbs by design and will run fine with pods, but you will still be susceptible to rain and wind, which will have an effect on how the bike runs, merely opening your legs a little when riding will produce a leaner condition, you will be best off using a dyno to tune any carb with pods {or any carb really} as it still takes time and if you aren't too sure how to do it yourself, you will be paying someone else to do it.... Just so you know its not an emotional subject for me, ALL modern race bikes and or factory built race bikes for 30 years or more use airboxes, its the best way to guarantee a stable supply of air and cut out the turbulence that is problematic when tuning carbs, correct length velocity stacks are also part of the equation, i'm more into the tech side of things than the emotional side... Just a side note, the CR's and RS's would still be easier to tune and run better for street application, with an airbox, the problem on the old Honda's is that you can't fit a bigger airbox, so it also has its limitations {smaller limitations on the street than the track}, look at the size of the airbox on modern bikes, they have far more volume than our old bikes. Thats another reason you see old hotted up Honda's with modified airboxes to get more air in, there are quite a few examples on the forum.... Just something else to think about
. I'm running airboxes on all 3 bikes i have, a 900, a 970 and a 1000, all will have airboxes, Also looking into having a carbon fibre airbox made, just because i can, can't wait to smoke the pod guys...
