Alright guys, I need a little help. I'm trying to get the needle valve seat out and it won't budge. I've tried three different pair of pliers. Removed the carb from the bike in order to get more leverage and that didn't work either. Any tips?



Also, the bike had the oil filter with 4 slots but NO holes. I've had it for 900 miles. What, if anything, has this done to the motor?

Thanks guys. I'll go get some acetone and ATF (automatic transmission fluid, correct?) this week and give it a try.

From what I can see in the picture, it's the right one. Be sure and open the bolt on the head to make sure oil is reaching the top.

The pleated mesh is just a newer version as I understand it, but you want the four holes for sure, I hope you haven't suffered damage to you bike.

Just an update on the needle valve seat removal. Put the acetone/ATF mix on it, still couldn't get it out using vise grips. Tried to tap it so I could put a bolt in it for more leverage and the tap got stuck. Attached vise grips to stuck tap and I pulled the carb while my dad pulled on the vise grips. I'm 5'11" 220lbs and my dad is 6'7" 260lbs and we're both pretty strong. Took about 5-10 seconds of pulling before it finally broke free.




That still didn't solve my leak, so after I had the whole bike reassembled I decided to check the petcock. Sure enough the petcock was leaking. Only bad thing is in order to remove the seat, I have to remove the Pelican mounted to cyclerack. Being as I tore the fuel line getting it off the barb, my dad had to hold his finger over it the whole time I disassembled the bike. Long story short, there was a perfect little groove going from the main fuel inlet to the fuel outlet in the petcock so I'm going to the dealer Tuesday to get a new gasket. Carb looks, and more importantly IS, a lot cleaner though!

How to remove Needle Valve Seat

DSCN3156.JPG This is what I did: The needle valve seat is the perfect size to accept a 1/4" NF tap. After cutting threads I used a 1/4" NF flat head machine screw installed in the end of my slide hammer extractor and with a couple of taps out it came.

Great idea. Thanks for passing on the information on the closest tap size that fits.
