Please do. U'll be doing many of us a favour.
I browsed a bit searching for judder/slippage in honda developed CVT's. Turns out the problem isn't limited to cng users. Honda of north america actually issued a service bulletin recognizing this problem and extended warranties to 7yrs/105k miles on honda developed vehicles employing CVT. I also found that the CVT judder issue was addressed by honda in 2006. Interestingly the cng installers i have talked to concur to this by saying that there is no problem of cng in 06 onward models.. Most of the times(almost 90% of the posts i came across) the problem arises due to a delay in CVT fluid change so make a point to replace that at honda's recommended intervals. IMHO, it should be changed even more frequently than those recommendations. Better safe than sorry.
There is also a honda prescribed remedy for the judder/slippage provided you follow it as soon as the problem appears. The procedure is called "CVT Burnish".
Details are as follows:
Do a complete drain and refill with honda genuine CVT fluid. Then brake torque the vehicle in D at 1/4 throttle for 30 seconds. (about 1200 rpm). This will burnish the start clutch. Re-do the procedure 2-3 times(collecting and using the newly drained fluid)
