Sprag clutch cleansing, oil leak

Post by johnny42 » Fri Feb 14, 2020 12:06 am



I recently overhauled my starter motor (thanks to folks here that helped) and next season I will add Seafoam to my oil for the sprag clutch cleanse.

I've read concerns about using synthetic oils in older wings which might start oil seepage. So I'm thinking wouldn't using Seafoam to clean things out also risk seals/gaskets to seep oil?

But.... I need to use the Seafoam to hopefully correct the sprag clutch issue and I will. But I like the idea of using synthetic oil. I've only used conventional all this time.

Need opinions or evidence on how good a test using the Seafoam will be on whether it causes an oil leak. If I do the Seafoam, drain and refill and there are no leaks, is it a good sign using synthetics is OK? If the seals are weak, will doing the Seafoam cleanse cause a leak right away? Is the Seafoam going to clean out the grunge and then let the synthetic finish the job of creating a leak?

I will use the Seafoam but don't want my bike to leak oil......as most of us do.

I've heard of Synthetic oil causing leaks, but like everything else you read on the web, only believe half of it.

I bought the '93 wing three years ago, PO told me he was using Shell Rotella T6 5w40 synthetic diesel oil in it, inexpensive at Walmart. I used to put Valvoline Max-Life 10w40 (Dino/Synth blend) in everything but decided to keep using the T6 in the 1500. Since I don't like stocking multiple oils in the garage, now Everything around here is using the T6, Cars, bikes, even the lawnmower.

I can't say that switching from a Dino/synthetic blend to full synthetic has caused any leaks that weren't already there. The 5w40 is a little "runnier" than 10w40 when cold.

I like to ride in the cold.
So what weight of oil should I use for 15 f and above temperature?
The Honda 10 w 40 won't turn the engine over. I tried using sea foam with my last oil change and the starter still just spins.

I think they make 0w30 or 0w40 diesel oil, that should help in cold temperatures. Be sure to confirm in the API donut the bottom half is blank (no friction modifiers)
