Ok i know seafoam thins oil. I read in some previous posts on here that there is such a thing as detergent oil. The reason i ask is somewhat of a long story but i have a hard shifting problem. I think this is due to gunk on the cogs of the tranny shafts.

I know it could have other causes, but i tore the whole motor down and replaced nearly every worn trans components to fix a shifting problem on my bike.

Now, i found little chunks of gunk in the oil i drained out of a recently rebuilt motor, i think the gunk is all over the inside of the motor.

Is there any seafoam alternative, or a safe way to use it in the oil?

Run seafoam and a thicker oil like 30W to compensate the solvents in seafoam, or is there a safer alternative
Could ATF work, i read that on here, but may be misunderstood
Thanks for looking gents
sincerely

Did you closely inspect the shift forks for wear? Also the shift drum?? I just don't see "gunk" being the problem..

I'm not too knowledgable on transmissions but others here are pretty good with them..

I was always under the impression that before you change your oil, you should top it off with a little seafoam if it's down. Run the bike for about 30mins to an hour, and change out the oil.

shift forks are fine, same with the shift drum. There are chunks of gunk in the oil.
