Just picked up the bike today and the carb has been sitting for like 2 years with fuel. I'm having trouble finding parts and I'm not really familiar with this particular carb. So my question is where is a good place to get replacements and do you think i would need more than the needle, possibly a float, gaskets, and maybe a rejet (full exhaust in the works). Where is a good place to get different jets? Also while I'm in there, is the pumper carb upgrade worth the trouble?

 

Kawasaki parts are readily available and if you click on the cheap hop ups link in my signature you would get a listing of parts with Kaw numbers to upgrade the jetting of the CV. Unless you damage the gaskets there is no reason to replace in most cases. Key thing though is to put the diaphragm/slide in a cup of hot water to keep the diaphragm from changing size and not fitting back in. That is mentioned in the cheap hop ups too.

Motorcycle carb rebuilds are different from car carb rebuilds now. With the neoprene gaskets and O-rings there is no need to replace them in a rebuild unless damaged. So rebuild kits are few and far between for the carbs since the 80s.

 

The pumper carb is universally praised by all that put em on.. Some even think it should be the first mod done to a stock bike..

Unfortunately, we do not have dyno charts to show proof of the benefit but it is safe to say that rather than redo your CVK, spend the money for a pumper and you'll have spent wisely. The "pumper guys" in here will tell you what all "extras" you'll have to get in order to properly setup the Tm36-68..

 

Just tore the carb apart yesterday on my 2007. Had a new float needle that I put in as well as a re-jet. The Dynojet kit comes with a new needle and spring which changes the fueling rate as well as a selection of jets to choose from depending on your mods and altitude. You can also drill out the choke circuit a small amount to give easier cold starting. Order the drill bit before hand as its really small(0.018"). I though I had one small enough but not even close.


Expect to take the carb apart a few times if you want to get the jetting "bang on" and then again if you do any mods like exhaust.

I'm in Canada so I ordered the needle(OEM) and Dynojet kit off an online parts warehouse located in Canada. I'm sure there are lots in the US to choose from and with the small size of the parts shipping is generally cheap and quick.

 

Just in case anyone out there was having the same problem. My bike would start, but the rpms would surge then after it got warm the bike would fall on its face and die any time you touched the throttle. Well I got it running great today and all i did was put the air box lid back on and fill it with fresh gas. So i'm thinking the problem was old gas or too much air.

 

You certainly cannot remove the airbox lid unless/until the carb and exhaust are properly performance modded for lidless running..

 

ha well it was quite the learning experience.
