I will put on my MCCTs this weekend, just to rule that out. It shouldn't hurt anything. I don't understand the mechanism by which these would make noise when cold, and not when hot. But just because I don't understand something doesn't make it so! (Just ask my wife )To your last point, when my ACCTs started to fail the noise always went away when the engine warmed up. I didn’t wait long before swapping them out.
I suspect something in the valve train too. I think lifter. I would think an exhaust leak wouldn't just stop like this noise does, returning with rev up and stopping momentarily after returning to idle. If it was a leak that sealed up with heat, I would expect it to gradually get quieter as everything warms up.Jason, I sincerely hope you can get this sorted out & it turns out to be minor.
Hydraulic lifter not keeping up? Or slow to pump up cold? Exhaust leak? Sounds to to be in the valve train to me. To many products claim to free up sticky lifters to recommend one .
I have heard of replacing some oil with an equal amount of marvel mystery oil, , running for bit and changing oil.
I’m sure you probably have ruled out exhaust leak by now.
The internet conciseness on use with wet clutches:I spelled Rislone wrong. Don't know if it would make the clutch slip or if it works with synthetic oil.
"DO NOT UNDER ANY CIRCUMSTANCES USE THIS WITH WET CLUTCHES!!! IT WILL DESTROY YOUR CLUTCH!!!" (usually followed by numerous insults flung towards those that chose to use it...)
"I have used this in my year brand model with every oil change for XX,XXX miles and never had a problem. It cleared up my issues immediately!!!" (Also followed by numerous insults flung towards those that chose NOT to use it...)
AND both sides claimed to have a brother that works at Rislone that they called and got direct approval to use the product with wet clutches.
Sometimes I hate the internet....though this forum seems to be one of the few good ones! Never-the-less, I'm no closer to knowing if it should or should not be used with wet clutches. I guess in the worst case, I have a spare clutch from my old bike...
