yamaha rt180k carburator parts (yr 1998)

 Where can I find the best deal for carb rebuild parts for a 1998
yamaha rt180k?

What are the best forums or web sites for general trouble shooting
tips?

Thanks.

 
So I found this site and the prices for just these two parts were $50

2MW-14107-25-00    NEEDLE VALVE SET
3VC-1490J-00-00    NEEDLE SET

I didn't figure I would pay 25% of the cost for a complete carb.

I hope there are better deals out there.
