Help clicking noise

I went riding on Sunday and did a lot of starting and stopping. My bike does not like this
kind of riding and quickly the battery was dead so I had to kick it back to life every time
I stopped. I hate kicking this bike as it always takes several kicks and being on the left is
very awkward and I also feel the kicker seems to high and I am 6'3". The bike also got
hot a couple of times and I had to add some water.

I decided that I needed to do something about the carb since the bike is such a pain to
start , especially when it is hot. I planned on sending the Dell off to Linanweaver but I
had the Mikuni off my wifes te250 laying around so I figured why not give it a try. It is a
TMR 36, very similar to a Kehein fcr 37. I figured it may be a little small but what the hell
it was worth a try. I mounted it and it fit right up pretty easy. I started the bike and It
started much easier than usual. It would idle ok with the choke on but not very good
with the choke off. I figured it was probbably going to be to lean as it was jetted for
a250. The most troubling thing was the loud clicking noise at idle. It would go away when
I revved the bike or at least you could not hear it as well. I think it is the decompressor
from the kickstarter that is making this noise. I did pull on the cable pretty hard when
removing the old carb. I should have removed the cable but I was being lazy. Does this
even make sense? I am not sure where the noise is coming from but this is my best
guess.

I was thinking about disconnecting the auto or kickstart decomp but was unsure nif that
was a good idea. Would I simply unhook the end from the head or remove the whole
thing?

Any ideas would be great. What about using a carb that small, if jetted correctly would it
work ok. I do not care if I lose some top end because where I mainly ride I am lucky to
get above third gear.

I am pretty sure it is not from the valves. It is not a fast ticking noise but more of a slow clank. It was fine on Sunday when I shut it off and after I put the new carb on and started it is when the noise started. I thought it may have something to do with jerking on the decomp cable that goes to the kicker. I noticed when I was kicking the bike trying unsuccessfully to start it that the noise was the same when the decomp would click back if that makes any sense. I assume if it were massive engine trouble it would get much worse as I rev it not less.

I will be sending the stator to sparks in the future for a rewind as I am sure this will help withh starting issues. I also plan to eventually dual sport the Berg as I am going to get an 08 KTM 300xcw (e) for a woods bike and I do not think the berg will get as much use as my main riding is very tight areas and the Berg is a handful on these trails. I want to eventually put some nice lights on it so it would be road worthy if need be.

I hope you are correct about the noise but I am not too optomistic. I started the bike this morning and it still made the noise. I do not think it has anything to do with the decomp arm because it was not moving when the bike was running. It is not a constant or steady rythym. It sounds kind of like there is something on the loose in the motor. I am not going to restart until I get a new water pumpseal and gaskets from Boss. I will check inside the clutsh cover and see if anything looks out of place as well as taking off the valve covers and checking the valves and trying to see if I can see anything loose. If I do not find anything should I go as far as pulling the head? I hope it is nothing serious. It is the 02 and does not have the updated rockers or bearings as far as I know. Could this be a possible place to look. I love the four stroke but there are some things I will really like about the 2t KTM, much simpler motor.

I appreciate the replies. I put the Dell back on and could not get it to start. I got frustated with it and took it back off and put the Mikuni back on. I the remembered that I had screwed with the idle on the Dell when I had it off which is most likely why it would not start. I started it again with the Mikuni on it and it did still make the noise. I will pull the clutch cover off anyway to replace the water pump seal and gaskets. I will check for any signs of trouble. I guess if I want to check the nut on the main I need to pull the entire clutch and basket? I will also check and adjust valves just for good measure. I hope the noise is from the carb or is something simple and obvious.

By the way I got my new 08 300XCW estart Yesterday and took the first ride today. This thing is awesome. I hope the new Husabergs get some of the frame design form the new KTM'S. The bike is so light and the estart on the two stroke is really cool.

Thanks alot, I will report back what I find.

This is on the Mikuni carb. The pilot is a 27.5, main is a 157.5 and idle does not have clicks but it is set where the bike will run at apprx. 1500 rpms. the fuel screw is 3 turns out and the needle is raised all the way up. I went richer on everything compared to when it was on the 250. My thinking was the bigger motor would need more fuel. I also adjusted the ap for maximum squirt. When I started it with this set up it seemed to idle ok and revved smoothly. When I get the new water pump seal in it and put it back together we will see how it works.
