It's a concise site, but a little monotonous, I suggest you change the color of the background of site and make your site more colorful!
Looks clean but we can attempt to make it look a bit more clutter free. This is just my opinion as a third party. The benefits you are offering for potential for signing up for the forum is full access and ad removal. If its a new forum that you looking at then may be you should think of displaying ads a little bit later rather than right at the start. Less ads may make your website look more presentable. As far as sign up is concerned users might anyway have to sign up to gain full access to the forum. Just my thoughts
You need a better designed site for that domain and idea. I am sure that you can be at top5 unofficial forums.
I like the design man...I think that is a sweet site....looks like it's getting some traffic too...good job!
It's a good marketing investment for forum community of a popular and wealthy brand but I think it's should be more exclusive with the Yamaha topics like some generic auto parts and all.
Your log is very good, I really like it, but you should thing about design. Maybe you could change background color, and use other typography. It is good idea just work on design.
Your domain name is really cool, design is ok but color scheme is looking good. You should add more nice images
that google adwords link right in the middle is annoying. it makes people click out immediately. pout it somewhere else.
Ditto hellandback. The big Ad is very distracting and puts me off immediately. I have no interest to go any further.
