HOW TO: Rebuild Honda CB200 CL200 CB175 CL175 SL175 Motor Engine

[@Raptorau]

Hey mate, this popped up at the right time - I'm just about to get neck deep in a CB200 rebuild. Thanks for sharing!

[@anemone104]

Thanks. Enjoyed that. The single carb no starter motor engine with four speeds from the CD175 is pretty much identical. Even the older sloping cylinders CD175 motor from the early '60s is similar enough that parts are interchangeable. I've had dozens of these motors apart - I worked for a bike breaker in Uni holidays. I put together a CD175 with a CB175 head and cam (twin carbs), CB200 gearbox (slightly taller top gear and 5 speeds), CB200 stator and regulator/rectifier (12v) that I put tons of miles on and went very well. Marzocchi shocks, valve springs and thicker fork oil sorted the handling and a CD175 (or early CB200) 2LS front brake in 18" rim sorted handling and braking. Achilles heel of these motors is the oiling system. Change the oil at 1500 miles max and clean out the centrifugal oil filter every second change, and they will do very high mileages. Neglect changes and don't do the filter and they will go bang, eating the cam bearings and then the followers (rockers) and cam lobes. Talking of camshafts, Joy Engineering here in the UK used to do roller bearing conversions and cam reprofiling for these motors and the 250 twins. I think they're still going, so if you can't get a new camshaft, they may be able to sort your old one.... And tension the cam chain frequently. I've seen heads with huge gouges in the chain tunnel, almost worn through to the tensioner. All that ally swarf gets into the oil ways and causes engine death. You should just hear the cam chain rustling at tickover - if it rattles like yours does, it's too slack.

Good to see you getting your hands dirty again 👍 it's a neat looking bike , well done.

[@tomaslindberg6296]

Tanks for sharing those mistakes whiteout feeling ashamed. We all make them. Nice animations. I would have changed the cam chain tensioner. The rubber wheel looks a bit chewed up.

Overall You did superb You have rebuilt the engine It runs We all slip here and there Fantastic job May be next time get some Jb weld and epoxy the broken piece back on to the cam end.

This video probably took so much time to make. Great video

[@derekbanim3638]

Really enjoyed that video and thanks for showing the possible pitfalls well done. You mentioned a link to the service book, I cant find it.Any chance of adding it ?

[@ssenssel]

Great stuff. I'm fascinated with stop and motion videos. How long does it take to film and edit a 1 minute S&M clip? Keep churning out videos, buddy. Cheers from Brazil.

Hey there luv your vid. Was it easy to replace the oil ring as I did break mine removing it and just about to install the new one. 🤞

[@ThisOldJalopy]

The new ones weren't as brittle and I didn't have any of the break, had to cross my fingers too

[@henryjobey255]

What product did you used on the cylinder head gasket as it seemed to be coated in something ? Just as I’m about to rebuild my engine

[@experience19811891]

Hi there! Thank you for this video! O own a Honda CB 175. Fun bike! When do you know that you need to do a rebuild? Thank you!

[@icanseeyouallfromuphere]

Without doing the gear selection mechanism in the video you've not really covered the title of the video, for some reason the video goes from fitting the upper and lower together, next your doing honing?? Then it goes to a cinematic refitting the clutch etc but it totally misses the gear selector positions, which is what my manual hasn't got I was looking for,

[@ThisOldJalopy]

Yeah, my bad, I did skip over that part.

[@icanseeyouallfromuphere]

@@ThisOldJalopy I sorted it in no time anyway, thanks anyway ✌🏻

[@outdoors_life7544]

Was this bike running on one cylinder prompting you to investigate it?

[@rogerwebb2058]

😅is it possible to use a 175 head assembly on a cb200 engine? Or maybe use the cb200 cylinder jug and pistons on a cb 175 engine.

[@martin-vv9lf]

I had this bike in the video and fitted a 175 head from the similar honda with a tubular pipe chassis. while the head fit fine the angle for the carb was off by i guess about 30 degrees, so that would require some welding or machining.

[@mikebrown1479]

Is it possible to redo the top end without removing the motor completely?

[@anemone104]

No. The head/cylinder studs are too long. But I expect you've found that out.....

[@icanseeyouallfromuphere]

😂I'm now sat waiting for out of hours doctor to call cause I couldn't get the cylinders to slip straight the last bit, the pistons slipped around and down on the crank, two of my fingers where under one of the pistons, crunched between the piston and crankcase, it didn't hurt, then it did, I had to literally grapthe cylinders under my arm and shake them up and still had to pull my fingers out of the gap, little finger nearly took the nail end off, half inch horizontal angled gash into next finger, no... pistons not in cylinders

[@nismoserspecv03able]

Cl175 has a cam chain master link 🤣

[@anemone104]

So do CD and CB 175s and (I think) the CB200. I hope our man didn't put the cam chain in so that if there was a split link fitted, it was the wrong way round.....
