Default Red Silicone in Cranks

i have tried to go back as far through, to see if it has been asked before.

Someone recommended this one time so I saved the website. I never got the chance to try it though.

hobbico red after run.
never had an issue with any other motor. ( i have had one come loose before, but was using novarossi after run)

well the real reason why i ask, haha sorry guys, i have a std flash 21 i have to do some work on. now the tuned version matches the crank hole nicely with the carb opening. but the std flash you see 2 mm or more of the crank towards the front bearing side. i want to remove the silicone and reshape the opening to match. then refill the hole. im trying out some red permatex hi temp RTV now, but i will see if i can get the right stuff. cheers.

So actually the putty didn't come loose in the Picco engine, or did it?

It's the silicone that most manufacturers use in the cranks.

It's self levelling.

thanks stefan.

i have let the threebond cure for 2 days now. as it is a test, i tried to get a screw driver in to pry it out, amazingly the screw driver will change its formation, but the filler wont even get close to lifting up from the sides. it has bonded it self very well to the crank. smooth and shiny finish , yet a little flexible. i will use the three bond from now on. quite easy to source, and a tube will do many cranks.
