If you can't get the Spectro, try the Amsoil Severe Gear. My dealer sells it $18.00 qt. I was using the pink stuff Red Line $16 qt at the local indy. When it gets really hot (hard rides on the twisties in late summer) it seems to break down with more gear noise and clunking than usual. When it's cold, the stuff is like glue. See Glider's comments on other topics related to Red Line trans oil. And the stuff really has a strong odor. I just swapped it out on the RK with Amsoil. I let it drain upside down for several days and still had quite a bit in the drain pan. Stuff is sticky for sure. My wife kept complaining "what's that horrible smell in the garage". Anyway, I'm not selling Amsoil but when I first bought the Limited, I had a tough time finding neutral (typical for a new bike as many have said). I made the switch at 1000 miles and the trans shifted like butter, very little sound and neutral was really easy to find. Has not gotten hot yet so I'll reserve judgement on that until the end of summer but I have been on some long rides in the twisties then in heavy traffic the same day and it doesn't seem to break down or get noisy at all. Plus, no strong odor and it pours into the tranny like 40 wt oil. It took about 15 minutes to get the pink stuff to flow down the funnel. I went to about 20 stores to find Spectro but no one carried it although a bunch of places said I could buy (special order) a case...trans takes one qt. I'll be dead by the time I change the tranny that many times!
