Went with ELKA’s on Amazon where it says they’ll ship in 6 to 10 days. If that doesn’t happen I might as well go with Walker Evans. With WE there are more options to mount due to hose. 🤗
I’m guessing Racing Power Sports who ever they are (Amazon vendor) didn’t want the liability of not fitting since ELKA themselves aren’t guaranteeing fit. I believe that someone here took the measurements of the 520 and if was identical to the 500. So I don’t think it will be an issue there. Caution is advised since from what I understand they’re not returnable.
My only real concern was the external reservoir on stage 3’ being close to muffler heat shield which could negate the benefit of having it in the first place. I was going for 3’s for larger oil capacity/cooler operation and longevity
I ordered based on pioneer 500 listed on their site and specified I have the new 520. They didn't come back and say there would be fitment issues, and yes I ordered directly from Elca in Canada.
BTW Are you in Canada? If not why aren’t you going with W.E.’s. Functionally same as ELKA stage 3, but priced as stage 2. I went with ELKA thinking I can get em 6 weeks sooner. 😅
