Default 06 650 Brute Carb Problems

Hey everyone. I'm brand new, so bear with me. I have an 06 650 Brute. I used to ride in WV quite a bit but had some kids and let it sit up. I am now trying to get back riding again. When I went to start it, the carbs were so gummed up that the throttle wouldn't move. Long story, short... I tore down the carbs, cleaned them, rebuilt them, dumped the fuel tank, adjusted the valve clearances, changed the plugs and put everything back together.

Here's the result:

1. It has gotten very hard to start when cold. It has always been cold-natured, but now after the engine cranks it still needs help from the starter for a couple of seconds. Also, I have to give it gas while running full choke for the first couple of minutes.

2. It sputters at low RPM. From idle to about 10-12mph.

3. At cruising (above 10-12mph) and high speed, it purrs like a kitten.

4. After it warms up... No choke to start. It fires right up.

I keep thinking, it's a pilot jet problem. That's the one jet I couldn't take out. My repair manual references pilot screws and jets, but the pilot jets on mine are press-fit in and don't look like those in the manual. There are no wrench flats or screwdriver slots to remove the jet. Anyone else have these type of carbs?

Will shimming the needles, like I've seen in other posts, solve my problems?

Any advice would be appreciated.

Thanks for reading.

Thanks for the post, BruteMike. You drilled the top of the press-in brass fitting to get to the the pilot jet to back it out? Do remember what size bit? Is this common knowledge? How did it get assembled that way?

Thanks, blue brute. I don't have time to work on it during the week. I am going to tear the carbs down again this weekend. Hopefully, pulling and cleaning the pilots will resolve my issues. I'll let you guys know how it works out.

Default Solved

Well, I finally got the problem licked. Last weekend I installed new pilot screws... same problems. Yesterday, I synced the carbs and I was still having lean problems. So, one last time I broke down the carbs. I pulled all the jets, floats, needles, etc. I broke out my original carb parts and compared them to the new ones. I found that the holes in the pilot jets were different. The original had visibly larger holes. So I cleaned and installed the original carb parts and put the bike back together. I fired it up and took it out. No more low rpm lean condition. Runs like a champ. Moral of the story: BEWARE MOOSE JET KITS! Now I can get ready for my WV trip next weekend. Thanks for the posts blue brute and brutemike.
