Seeing that there are no performance parts for the CB200, my quest is to make it as light as possible. I plan on starting with the wheels and suspension. After days of searching ebay for 1.45x18 aluminum rims I've had no luck what-so-ever.
I see there are several options for 17 and 19-inch rims. Which way would you guys go: 17 or 19" and how will either size affect the bike.
Fwiw, I know we're not talking breakneck speed here. :lol: :lol: :lol:

I disagree on the 'no performance parts for the CB200' part.

I have an article reprinted from Cycle magazine's initial test of the CB200 in 1974 or 75. In the first couple paragraphs, the article describes the steady decline away from performance from the CB160 to the CB175 to the CB200 in it's then-disguise of gas-crisis-buster.

It mentions carb size decline from 22mm to 20mm to 18mm. It also mentions corking up (silencing) the exhaust from 160 to 175 to 200. It further mentions more sedate cam timing from 160 to 175 to 200. It sums it up with the speculation that it would be interesting to outfit a 200 with the carbs and exhaust from the 160 and the cam from a 175.

Not 'performance' equipment, I know, but there are garden-variety hop-up techniques - better airflow in and out.

Good luck with your project!

Thanks Kirk, nice tips!
She needs new carbs anyway so now I know what I'll be searching for.
I still would like to lighten her up a bit but I'm in no hurry. The little CB is one of four on-going projects in the garage.
Thanks again for your tips. They are much appreciated.

'nother tip:

A year or so ago, I downloaded a page from Megacycle Cams' catalog. It was the page for the Honda SL/XL/CB 100/125 engines, but on that same page, they DO list two hot-rod cams for the '74 ~ '78 CB200. One designed 'for mid-range power, increased torque' and the other 'ROAD RACE profile. Must use racing pistons & springs. Mid-range and high RPM power increase.'

Don't know if they STILL have it in stock, tho.

Jim, The f-160 racing group may have some leads on a WM-0 alloy rim in 18'' if that is what you want....... I'd stick with an 18 on the rear, with a WM-1 rim, but run a smaller/lighter tire to decrease the weight ....Alloy sprockets will also help....as will an axle from a dirter (same diameter, but hollow... think its a XR part).... Snail adjusters also loose a fraction of weight, as do Ti fasteners.......It's all about what you are willing to spend to gain fractional advantage......
This link has Many tips for a 175, that also apply to the 200....
http://www.jrbranson.com/HondaRacer/mainpage.htm
Also check the "Fowler Formula" about the 160's and apply to your bike, from this site:
http://www.groupwracing.com/images/GroupWcollage1.jpg , or the f-160 Yahoo group...

P.S. The disc wheel is going on my daughters C200 (90cc) street bike, but I'm thinking a CL 360 DLS Drum for the C200 cafe' version now that I know a good way to put a larger axled wheel on a skinny axle bike....LOL.... I'll post pics if it CAN be fitted....
