whats it take?

It's all about aerodynamics. I forget the actual speed (Hoofhearted knows it though), but there was a 50cc motorcycle that broke 100 at Bonneville. Mind you, it didn't actually LOOK like a motorcycle after all the body work was installed, but it was categorized as a 50cc cycle at the time.
 
I hit 94 (if my speedo is right) on my stock 360. I think I read on wiki they do a ton from the factory but not sure.

My CB350 said it hit 90 the other day, but it was very much in the redline. I'd need higher gears, but it wanted to give me more.
 
Gearing only helps to an extent. Higher gearing will allow the motor to reach higher speeds at lower rpm's, but might not have the torque to overcome wind resistance. Lower gearing gives you the power needed to overcome wind resistance, at the expense of the motor reaching redline sooner.
 
This is a long term project as my budget doesn't allow me to move but at a snails pace. So planning is of the utmost importance (to maintain best bang for buck) but so far performance wise I have rebuilt and re-jetted the carbs and removed the stock air box and replaced it with an UNI pod filter (without running the secondary red layer...it wouldn't fit and I oil the inner filter and live in a very dry desert climate so the outer red filter isn't really necessary.)

I would like to upgrade the cam but don't really know of any options (to be honest I haven't really searched much into it lately), I am saving the majority of my engine build for the summer when it's too hot to ride. Other than the can any thing else I could tinker with for a few more ponies? I'm debating what to do about the exhaust. I love the factory set up for the looks and nostalgia factor. But there HAS to be a more efficient alternative.

Any help is GREATLY appreciated , and I thank you in advance

Cheers.

BTW I'm going with a cafe inspired build. No paint all sorts of plated metals (nickle, bronze, brass and copper throughout)

I was watching some show on the science channel and a fellow with a "bicycle" hit speeds upward of 80mph... Now it did not LOOK like a bicycle but it was in fact a two wheeled human powered (through and through) machine. Albeit encased in a fiberglass capsule with a camera/monitor hook up so the rider can see where he/she is going...not ideal for the clostraphobic I'd say.
 
I would search these posts for everything. Re-gearing your could have positive effects. Dropping three teeth in the rear only will provide only one result. But, so people change 1 tooth up front and 1-3 at the rear. It has been 10 years since I re-geared a bike. I don't remember what I changed it to. I had an '02 SV650 at the time. I bet some has a great set up you could try. As for cams I swapped my intake cams for exhaust cams. That made a huge difference when combined with the port and polish job a buddy did for me. I was lucky it only cost me $40 for the sanding spools. He did the porting for free labor. I think that was him being an E7 and helping a young E5. The porting was just smoothing the rough surface and aligning the port. They holes were 4mm smaller on the heads. Throttle response was much smoother. All that work combined helped my SV It was a v-twin with twin cams. But, it all would work on our little SOHCs. Someone has done each of these. It's just a matter of searching the forum.
I am in the process of boring out my 350four to a 466cc. I will have to search for what the best cam would be. But, I will also enlarge the intake ports to match the diameter of the boots.
I hope I helped you in some way. You guys have helped me greatly. Good luck on your build and Happy Thanksgiving!
