Well, A while back I installed a nitrous kit on my VFR and started 'working' with it. I ran into problems with leaking valves, & the 20 oz. bottles hanging off the mounts w/o support at the back contributed to mount fatigue. The manufacturer was very helpful, replaced one valve & repaired the other @ N/C. I now have my bottles more securely mounted, have a 25HP jet in place, & will start playing around again this holiday weekend :^). If all goes well, I'll put in the final 40HP jet & have my passing gear ('little does he know that I am faster than he, in my formula three, tee hee' - obscure ref. to the original Casino Royale movie) :^).
