Hot Start Plunger

9 posts in this topic

The plunger on my 03WR450 has become stripped at the carb. I think I have gotten it tight, but is there a way to check if it is leaking? How hard, what parts do I need to replace/fix this?

Thanks

The hot start plunger is a cheap fix with a new plastic threaded nut assembly you can order from your dealer real cheap. The plastic thread strips very easily! Do not over tighten :)

NO! Do not do that! There is not a positive pressure in the carb, it will suck the soap in, not blow bubbles out like a leaky inner tube.

To check for intake leaks, I have heard spray the spot with WD40 or starting fluid and listen for changes in engine RPM.

I just replaced my hot start last night with an solenoid operated, handlebar mounted push-button activated unit. Pretty slick! PM me if you wanna know more.

I dont know about you guys, but I never, repeat never use my hotstart, never needed to and dont intend to start.

What I am about to embark on is a z-start clutch (thanks and qdos to Desertfoxx for sorting the fedexing !! :) ) but I want to remove the hotstart totally as I will be taking the clutch perch and lever off.

Can I just undo the cable and leave the plunger in? :D

Or is there a better way?

Cheers Deano
