I asked Spring Mountain 1) if the upgrade and new oil spec extends the service interval and 2) whether 15W-60 would benefit engines without the input shaft upgrade. Answer is "no" on 1) -- service int...

I just received my 1500 refresh back from Spring Mountain today. Inside is a memo that says "This engine has been fitted with the updated input shaft. This engine MUST now be run with MOTUL 300V 4T ...

@gabriel I am sorry, I do not. I referred to my other SR3 several times during the install. I am away this weekend racing (not Radical), but if you have some specific requests I can post pictures n...
