Performance camshafts can add different characteristics of power to your engine. Cams with high lift can add mid range punch, while cams with longer duration can add high rpm top end power. Cams with both can really add power but you need to make sure the head can flow properly. It really depends on what […]
It annoys me when I see cycles on eBay that say “Fresh rebuilt engine. 10 miles on it since rebuild. Runs great.” etc… Fucking stupid. I would never buy a bike like that unless the owner has put like 1000 miles on the rebuilt engine to confirm shit is good. Anyway… someone asked me if […]
Read about rebuild Part 3 Read about rebuild Part 2 Read about rebuild Part 1 Well… the 450 is finished and it runs. Video at bottom. I’ve riden it about 10 miles so far. Haven’t gone over 5K rpm yet, but it feels super responsive and eager to rev. It’s not dialed in yet though… […]
Read about rebuild Part 2 Read about rebuild Part 1 Hey guys. Here’s an update on my cb475 supersport build. The engine is basically finished. All that’s left is to put on my high polished engine covers and I’m putting in a new clutch. I installed new valves seals. Below pic – I installed the […]
Read about rebuild Part 1 Ok… So, I had a couple different machine shops do a couple different things for me. First machine shop: Mar Automotive 4345 Orchard Street, Philadelphia, PA 19124 (215) 288-7320 They’ve done cylinder head stuff for me in the past: – they did a valve job on my S2000 like 5 […]
It looks like I’m not putting a 450 head on the 500t cylinders. Everything on the 500t is in way better condition so I’m going with it. Here is the 450 with the 500t engine in it. So long semi-stock bike… See ya soon when you’re not as lame. Rip all the shit off it. […]
A few months back I had a little run-in with a car on my cb450. The result was a little bit of a dent on the right side of my tank. I don’t like dents, so i’ve been looking for another option for a new tank. I’ve never seen a NOS tank in person. It’s […]
As I said earlier in this post… cb450 and cb500t have no valve springs. They have a torsion bar set up. Let’s take a look at how exactly the torsion bar works. It’s pretty cool. Pic 1 – The engines are double overhead cam which means there is a separate cam lobe for each valve. […]
As I’m getting ready to order the parts for my cb475 supersport build, I’ve been looking at other cb450’s out there. I found this one on Bike EXIF. It was the bike of the day not too long ago. A shop called Blue Cat Motors built it. I dig it. It basically looks identical to […]
My work Drexel University is closed for the next 2 days because of a hurricane, so I decided now would be a good time to get started on my cb475 supersport build. Let me recap what I’m doing… I have a 73 cb450 that I put a 75 cb500t engine into last year. (Hence cb475) […]
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 […]
Perfect day for a short ride.
I’m dubbing this the ‘cb475’. I’m all finished and it runs fucking awesome! I had lost interest with this cycle, but now I’m psyched on it again. I’m super pumped on how smooth this engine swap went. Pretty sure there aren’t many cb450’s with 500t engine’s around, so I feel good about this. I’m gonna […]
– Spot painted the frame with a few coats of Rustoleum. I used a rust neutralizer spray first. I don’t care enough to take every little thing off and paint it legit. This is good enough in my opinion. – Wiring harness is at Ricky and Adam’s garage. Going to do the custom, bare-bones harness […]
I bought a cb500t engine to put into my 1973 cb450. There’s not really many reasons I’m doing this other than it’s fucking cool… Hybrid! The engine bolts right in. Should have a bit more torque. 1975 500t engine. 24,000 miles on it. Get dirty. Step 1 done. Next, I’m doing a slimmed down custom […]
Fairmount park is awesome for quickly getting out of the stop and go of the city and onto some wide open roads. Sunday felt like a real spring day so we took advantage. We met some new friends along the way that joined in for a quick ride. Roasting one of my favorite turns in […]
…was super tall from Honda. I could barely touch the ground flat-foot on it!!! So, I found a seat on eBay that was real slick looking that was said to fit the 1970-1974 cb450. This is the dude’s eBay store: http://stores.ebay.com/hondaclassic31 He def has some real sick seats for a lot of different bikes. Anyway, […]
time to get the cycles packed away in the garage, and away from the outside shit…
looking emo on the cb450. This was when my bro-in-law still had the 450. The summer he first got it. Now he has a sick Ducati monster.
So… after taking the engine apart it was apparent that we couldn’t diagnose the cylinder head properly. The cb450 in the 70’s has a really weird cylinder head design. Instead of having valve springs, it has what are called “torsion bars” which hit the valve to open it, and also, hit the valve to shut […]

Our buddy Colin is still fine tuning his xs750 triple up in Montana. He sent over these couple photos. Pretty rad looking.
