Rare EARLY VIN, CAFE RACER, CB650 Cam, Super Sport

Description

~1971 CB500 Four K0 Super Sport~

• Frame/VIN# 1002857

Meaning it was made 2857th of the first year of production of the CB500 Four.

• Engine # 1003111

Engine was made 3111th...These are "matching" VIN/Engine #s for Honda in 1971.
Comes with another tank and side covers, he 1971 brown version (which this bike was off the production line). The brown tank is in similar condition, ooks new with the one dent being on top and in a nice easy spot to repair. I will also include a very nice perfectly clean DENT FREE TANK that has been painted in the cafe racer style. Thats three tanks, o no worries on what to wear to the party. I will post photos of the other tanks and side covers as well as a video in the next 2 days.
The mileage is unknown because the one of the few missing parts when purchased was the Speedometer. After 1.5 years of restoring this machine along side 3 other cb500/cb550s with varied mileage, ith first hand knowledge of the engine internals, heir comparisons revealed a good estimate of this here beauty's mileage to be around 8-12K.
A look inside the top end and the cylinders, howed the stock pistons and rings all were in good condition. The tiny stamped markings on the rings were still clearly visiblewhich points indicates lower mileage.While in the top end I cleaned ALL the carbon build up on every part. It looks new inside. Valves and Seats were lapped until smooth, hey are air tight now, nd the # 3 exhaust valve was replaced. All new valve guide seals were then installed. Then to give the bike a HUGE BOOST in power the legendary CB650 camshaft swap was performed. The difference this upgrade makes is just plain awesome. This 45 year old machine has lots of power with rebuilt top end, erformance cam, nd its a lot lighter than stock with the 4 into 1 pipes... short muffler in place of the long and weighty 4 into 4 pipes took lots of lbs off her.
Carbs have been ultrasonic cleaned, nd freshly rebuilt with new o-rings and gaskets. The bowls and slide covers have all been polished. New tygon fuel lines. New Stainless Steel Hex screws are in place of the old float bowl screws which makes rejetting much easier. Speaking of rejetting, he carbs are still 100% stock with 40 pilot jets and 100 main jets. She runs very strong especially at low and middle rmps, ut shes loosing a little "umph" at wide open throttle. With the uni foam air filter and 4 into 1 exhaust I'd recommend 110s for the mains, he pilots should be just fine. 4 new 110 main jets cost less than $20. Needle clip is also in the stock position. As far as tuning the carbs, ou can change both the needle clip position and main jets with a screwdriver and hex key...and most importantly without the laborious task of removing the carburetors. I am willing to install any new jets if the buyer has them sent to my address.

Not-perfect-by-any-means ListOriginal seat cover looks really good, here are one or 2 tiny pin holes in the 45 year old vinyl. Front fender has some little scratchy-dings and some pitting in the chrome. Rear fender looks better but still has tiny pits that you can see when you get your face up close. Tachometer isnt hooked up right now due to the cb650 cam upgrade. The worm gear on the cb650 cam doesn't play nice with the stock 500 tach gear, o it required the removal of the cb500 tach gear. The cb650 tach gear will need to be installed before the tach will work. As of now the hole for the tach gear is capped. Otherwise, have the original camshaft and tacho gear gingerly tucked away in a box for the winner. For the over all aesthetics of this resto-mod build I removed the front blinkers, ut I can install them no problem at the wish of the winner. Currently the left tank emblem is off to show the tank dent. I will install for winner of auction.Tank is incredible to look at except for the unfortunate crease-like dent on the left side. Its a weird dent because despite its size, t sorta hides itself...especially when shes on the side stand. Neutral can be a little stiff at times, OT TERRIBLE AT ALL came this way stock in 1971, onda later issued a parts fix for this in a 1972-3 bulletin.Rear brake arm needs a longer shaft to mount to. I will fix before winner picks up.
I have a video of a walk around and drive off that will be posted in a link below in a couple of days. Thanks for looking and happy bidding!
