Honda CB350 Race Engine Build- 48HP

Sharing my build of a 1970 Honda CB350K full race engine. Techniques shown include engine assembly, piston measurement, valve spring setup, cam timing, dyno test and more.
This is not a full tutorial on everything involved with an engine build. It does not show porting, valve seat installation, oil cooler setup, larger cylinder studs, or special valve seats.
Motorcycles are dangerous.
It is the responsibility of the mechanic to build a safe engine. A blown up engine or oil leaked on a tire can cause a crash that may seriously injure the rider. This video is backed up with decades of professional motorcycle mechanic experience. This is not a how-to video for a novice.

Absolutely phenomenal work! Not only the engine build but the video production also. Thank you so much for sharing this. It’s been many years since I rebuilt my stock CB350 motor so this was a nice refresher. I also learned some new tricks. It really does take a lot of attention to detail to get 48hp but your hard work is handsomely rewarded. That micro serdi valve seat cutter was neat. I’m not sure I’m willing to invest the time or money to get another 50% more out of my motor but if I ever do I’ll be studying this video over and over again.

If you reduce the radius on the rocker arm skid you can get a few more degrees of overlap for nothing. I used to race one in the mid 70's Yoshi cam, ported high comp pistons 36mm MK2 Amals. Held the NZ quarter record in 76. Great wee bike.

Many thanks for sharing this, I race a CB175 here in the UK but using CB200 crank and pistons. I have learned a lot from your video and will try to impliment some of your head assembly techniques. I use all standard parts except for a cam regrind and skimmed head, so far obtain 21bhp at 11000rpm but on your scale some 27hp should be obtainable, so have a bit of work to do!

@stanlipert8513 3 жыл бұрын

Terry, exactly specific output is 132HPliter as a 362cc engine. 26-27 HP from 200cc is an excellent goal to achieve. Your 21HP is race-worthy at 105HPliter. Be sure to measure the clearances in the same way, piston to valve, squish clearance, and valve spring pressures.

Worked on the early Desmo Ducati's . Used to set at nil to 00.001 but had to install very week springs to ensure valve was closed when engine stopped, otherwise no compression to start. Once running inertia and compression did the rest. Early days of course, races started with dead engines , not like now with electronic anti wheelies, no rider controls. . Four valve heads too. Valve stretch, Steel valves versus head expansion rates had us thinking at times too. Great to see an expert at work, never did one of those motors really, road versions only. But lots of work on the CB77 versions. As quick as most Big British twins when set up correctly. Did more work on two strokes latterly, fun machines !.

Random question for Stan or any other cb350 aficionado, where are you guys getting replacement cam chain roller assemblies (the metal arm and smaller chain roller). You can find the larger roller for cheap easily on sites like 4into1 but that smaller roller is basically impossible to find. I also couldn't find any KA slippers or the Norda-bike replacements that are apparently the bee's knees in the forums. I ended up ordering a roller assembly for a cb750 because I believe they use the same roller and am going to make it work on my 350.

@Michael-ec6mg 3 жыл бұрын

Todd Henning Racing usually has the KA slipper tensioners in stock. Otherwise there is an ebay seller offering all metal replacement rollers but I cannot offer anything as to the quality since I have not used them myself.

Memories of thumbing through the Clymer manual for my CB350 back in the early 80's. There was a section on what modifications could be made for more power, but it didn't try to encourage the reader, saying that it would be difficult to make the bike competitive. I'm guessing things have moved on since then!

When the CB350 twin came out, Honda built and tuned a few full race bikes, and sold the race parts as well. These bikes have a true racing pedigree from the start. Search for "CYB350".

Ken, I keep the ports as small as possible for high velocity, until just before the valve seat it flares out. The port roof is raised in a pocket before the valve seat to flow better around the roof.

Exhaust are stock size, could be smaller. Intake are an enormous 35.5mm, requiring sunken valve seats to achieve valve to valve clearance on overlap, plus X5 cam, as first designed by Todd Henning, as the "big valve" cam. Valve stems are stock, robust 7mm. They can take some valve to valve hits without breaking off the heads. Ask me how I know this!

I rechecked the unbroken clearance on the remaining valves and found it to be 0.020” Do you think the valve to valve clearance changes over time? I’m not sure what the clearance was originally on that head. What’s the story on your 7mm valve stems? Was there evidence of a collision?

@@stanlipert8513 damn what a bummer brother! I wouldn't be more than happy to pay you whatever you're asking price is, I just want my cb350 motor to be able to do more than just 95/100 MPH, and with the only 32 horsepower from the factory you're not going to get that, I would kill to have that engine of yours in my frame, well if you change your mind brother I'm just a quick message away, absolutely awesome, unbelievable work you did to that motor, man what I would do for that motor!!! By the way have you gotten at top speed run on her yet?

Hey Stan I had a question brother, what was the top speed reach on the dyno pull of yours? I am extremely curious of how fast you can go with 48.2 horsepower on such an awesome light bike...

@stanlipert8513 4 жыл бұрын

Bike speed on the dyno is zero MPH, top speed on the race track is north of 115MPH, but I have no speedometer.

@@stanlipert8513 I have a 74 CB350F. Would you be willing to build the motor? If not, any recommendations for someone who can build the motor with reliable power? I live in Georgia, north of Atlanta but I can always ship the motor.
