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.
