Orange stuff in crank

Does anyone know what type of material that orange thing is in the JP crank?

I may be mistaken but I think it is high temp silicone. If I am wrong I'm sure people here will tell me.

It's an epoxy used to make ramps and fillers on the inner of the engines. Isn't affected by fuel. Get to your car parts store and ask for Araldite or loctite epoxy (get the resin and accelerator bottles).

The best is one that converts from a medium thickness resin to full hardness on 6 - 8 hours. It's harder than the fast curing ones.

Seems that the resin that uses JP is the Loctite one. Clean and deburr a little the metal parts to get a proper grip.

And apparently, I also read somewhere (maybe on this forum) that it's a no no using WD-40 on this ramps used in the JP engine.

Why is it even there? What does it do? I am obviously not seeing things right.


*wait, so it is made to lighten parts such as crankshafts?*

no it channels the air through the crank better. it's like a slipperydip for the air

...interesting....

Doesn't seem very useful in my eyes, but when you go all out on a motor, you are supposed to go all out.

Well it looks that I have a 50% chance of being correct, but then what do I know about motors right Jason100776. I do know never mind.

The ramp does help channel the air from the carb but its main purpose is to gas flow the crank more effectively to maximise the fuel efficiency of the engine.

My friend, that mods engines, spoke of watching water flow through a crank before and after modding...It flows faster and larger after adding the red stuff.

SO has anyone tried to put this in their cranks themselves? Did it work? If so, what exactly did you use?
