If you have a cb650 (or any jap 4cyl) and you’re looking to splurge close to an extra $1000… This post is for you. 79-80 cb650 actually have pretty good stock-oem carbs IMO: 29mm bore, mechanical slide and accelerator pump. However, if yours are getting shitty and want a nice upgrade, brand new keihin crs29 […]
PA trip was so much fun. Like we always say, getting out the old bikes to camping and checking things out is the best. We only had 5 days on the road and I think we made the most of it. Photos by Alex and myself. Day 1: Met up at Ben’s garage and then […]
I like where my license plate sits on my cb650. See if you can find it in the above pic. Yea… it’s sort of hidden, but it’s also sort of visible from certain angles. I’ve ridden in front of so many cops through the city for years, and no one has ever given me a […]
I had been looking for a while now for Piston Kits for my 3 bikes. The Z1 is a no-brainer. Weisco makes anything you need for a Z1 / KZ900 / KZ1000. I was having a real problem finding kits for the cb450 and cb650. I eventually found kits that drop right in after a […]
Blasting the highways around Philly when there isnt traffic is so much fun. It’s quick shot south from my place in Kensington to Ed’s place in South Philly which I did this past Sunday. It was an easy decision to take a break in the workshop to bring some tools down to Ed so he […]
– – – Scroll to bottom above the comments for an update… Jesus Fucking Christ. My rotor shit out again yesterday. Where do I start? This is going to be a long post. So, the 79-82 Honda cb650 has a shitty charging system. I realized I’ve never made a post explaining in detail. So, here […]
I was bored the other day, so I took some pics down at FDR. Messed around with low-lighting. I wanted the bike to look dark and rough. I dunno… just messin around.
Seat is finally 100% done. Took about 2 months from conception on paper to finished product. It was my first time doing metal stuff like this. The seat def has some minor imperfections… but it has character. I designed the pad, and had someone upholster it for me.
Got the tail light on today. Looks pretty cool. I’m psyched. Now all that’s left on the seat is to sand down the top, and coat it with Boeshield T-9. Seat pad is at the upholstery place right now getting made.
The seat isn’t finished yet. But at least it’s on the bike now. It’s rubber-mounted in 4 spots, distributing my weight, so I’m hoping the seat doesn’t vibrate to death and break itself apart. Fingers-crossed. Made some gusset brackets for the mounting hinges. Good idea adam. They look cool. License plate… crotch rocket style. Right […]
New seat is 1/2 of the way welded. Pic below is a mock-up of it on the bike with a seat pad …just so you you can get an idea of what it’ll actually look like on the bike. I got all the pieces to fit almost perfectly. Then I spot welded it together… Then […]
So, I’m still working on the seat for the cb650. This is my first time working with metal since high-school metal shop. So, it’s been a while. I’m pretty much winging it. Below are my steps for figuring out what I’m doing and how I’m doing it. So far it’s turning out real good. I’m […]
Below is the info you need to get pod filters dialed in on your 79-82 cb650. 79-80 (mechanical piston slide carbs) 120 main jet (stock is 92) *** try a 115-117 if you’re at high elevation 42 slow jet (stock is 35) *** try a 40 if you’re at high elevation. Drill out the 35 […]
The 650 rebuild is finished. It’s running pretty damn good. Going easy on it for the first few hundred miles. Here’s what I did in the last step: – Re-did my wiring, I cut out about half my wires. Props to Adam! – Installed oil cooler – Spot-painted frame – Re-mounted gauges lower and tighter […]
I’m adding a vintage Lockhart oil cooler to my 79 cb650 for several different reasons. Read the below article. It def outlines a couple of my reasons. Side note: To make the oil cooler set-up work on most old 70’s 4cyl hondas, you need a special adapter plate which sits between the engine and the […]
Cleaned everything as best I could, then I took the head and cylinder jugs to Mar automotive in the near northeast. They cleaned and checked everything, installed my new valve seals, cleaned up the combustion chamber, intake and exhaust ports. They also said I had 1 leaky valve, so they fixed that too. Turned out […]
I’m rebuilding my 79 cb650 engine. The engine leaked a shit ton of oil from the rubber o-rings around the head gasket. (Common 4cyl problem on old Hondas.) My engine fins have always been completely covered with caked on oil, grease and dirt. If you didn’t already know, the engine fins are what cool your […]
Do your forks leak oil? Mine did. This is about the same on all old 70 honda cb cycles. * For a complete, exact step-by-step tutorial, consult a real manual. I’m just gonna give the basic steps. Step 1 – Find a 17mm bolt. You have to loose the bolt on the top of the […]
Adam kept bustin my balls for having the original brake cable all long and stupid, so I finally bucked up and bought a new stainless steel braided line. I guess I didn’t read the fine print in the eBay post because when I got the package in the mail, there were 3 cables, bolts etc… […]
…on the cb650 the other night right before a ride. I found a used set on eBay for $27. Got them in the mail in a few days. lubed them with various cleaning / greasing shit cleaned the throttle sleeve and put a thin layer of grease between the sleeve and the handlebar to keep […]

First step in modifying… Take a good part and render it useless. I’ve also found that one of my favorite bikes is based off a 77 or 78 CB750F that has a wheelbase of 58.9″. My modifications should give it a comparable look with the rear wheel placement. ****EDIT the wrenchmonkee bike description says it […]
