Hi EXILE----------- go to the Left Hand column on this page, select TECHNICAL NOTES --- then CARBURETTORS and all will be revealed from our hosts experienced Technicians ---- and it's ONE STEP AT A TIME !!-----I'm not trying to lecture but when dealing with carbs. then that has to be your golden rule...

Alan: I've read the tech. notes here and Googled a load of other stuff too. Some I kept, some wasn't comprehensive enough. Generally I think I know what is wrong. Specifically, I'm not sure. So for now, I have to go with trial and error. First things first though, I have to get the new intake rubber and fit it all back together. Adjusting the stop by one degree of movement was, hopefully, a necessary evil that would have had to be tackled anyway. Indeed, I was on my way there before I found the cracked rubber. And how could the engine run rich with that going on? It should have been lean due to the false air supply, but a blackened, sooted plug can only indicate too much juice, too little air.

I am truly glad and grateful for all the advice and the knowledge I can gather here. It is greatly appreciated.

As I said, moving the throttle stop can be reversed (and may have to be) but it may also be the solution to a simple, though irritating, problem. If that is so, then I guessed right and all will be well. If not, I'll be up to my elbows in spanners and stuff for a little longer than I hope I will be...

My thanks to all for chiming in here. I'm noting all this down.

Hi EXILE--------ok, situation understood....May I ask that we all use the accepted engineering terminology for the various parts etc....So that is the needle clip and for initial diagnosis should be placed in the centre groove of the needle itself ( This is position No3 in a 5 groove needle starting your numbering from the top of the needle)...The throttle stop is usually incorporated within the twist grip to prevent the cable being over tensioned when on full throttle setting......So what is the bike we are dealing with here then and why is the carb "Dangling on the throttle cable" in the first place ??

Hi Alan.. it's a bullet 500, Indian built in 2005. Technical terminology? Well, I'm good at that. I know things like 'big round bits', and 'the sticky out thing on the end' and even 'the big thing on the end of the little thing that goes round' and the 'wotsit' and the 'wossisname'.

This is why I take pictures. Then I can point 'em out.



The carburettor is danglig at the moment because the intake manifold hose is cracked about halfway round its circumference on the cylinder intake manifold side. The engine was running rich and I went off to investigate. The result is described elsewhere on this particular thread.

I've been to my local bike shop, they can't help, so it's off to H's for the part.


I'm so glad I'm retired now. I have the time and the patience.... (Bollocks I do, but it sounds good..!!)
