2000 Husky TE410/E Idler Transponder Assy

I noticed an oil leak coming from the Idler Transponder Assembly. I replaced the O-ring and the sucker still leaks! I guess I could try to use a heat resistent silicone but I know it will turn to mush after time. I wonder if I could use a bigger O-ring though I don't think it will fit. Anyone have any solutions? Going to Terlingua in March and I hope to get this resolved ASAP. Any input would be appreciated.

What is Idler Transponder Assy.? George

Some electrical device that is towards the bottom of the engine on the left side of the bike. I am not sure what it's function is. Hence Idle so it might have to do with something on the choke? I am not so sure. I just know that it leaks like a siv.

You called it as written in the manuel. Here we call it the Neutral indicater switch. When in N turns the N light on the dash. Doesn't have anything to do with choke.
Check if is cracked try get it clean and dry then use some Hi Temp silicone should stop the leak. Make sure the spring goes in first then the brass plunger with the bullet end facing out. Later George

Thanks george! I was able to get a new o-ring and behold! The other o-ring I used was a bit fatter and seals nicely. No more leaks!! My dad had the bike before me and he never had time to replace the o-ring. He did use the hi temp silicon but over time it got funky. I noticed the original o-ring was skinny compared to the new one. Thanks for your input i do appreciate it.
