I use the Clymer Honda repair manual for 1978-1987 400-450 twins for all the required maintenance including engine work even though my bike is a 1988 model. (The only year it was imported into Canada.) I was able to completely disassembly and reassemble the engine using the manual so even though it doesn’t cover my exact year, it still has good information. Valve clearance given in manual – Intake, 0.08 – 0.12mm (0.003 – 0.005in.) Exhaust, 0.12 – 0.16mm (0.005 – 0.006in). Hope this helps.

I saw those in Brazil in mid 80′s in a vacation, I took a closer look at them because a I owned a CB450T Hawl, they were made in some factory in Brazil, the streets were crowded with the lesser model and this one

I’m wondering if Isabel ever found out what was causing the power failure. I’m having a similar problem (in my case, the power level drops suddenly but then can come right back again) but I think I’ve traced it to a coil that’s starting to break down. Has anybody tried replacing the original coil with a coil from a different but similar bike? I wouldn’t want to go long distance on my 450 but it’s terrific as a commuter bike.

Just bought a 450S and unfortunately found out there is some kind of power failure. If I try to speed up a bit, the speed just drops down to 80/90 km/hour.
If anyone recognizes this problem, please let me know!

I used to own a 1988 CB450S, purchased used in St. John’s, Newfoundland, Canada in 1995. I rode it for about 12 years, putting close to 80,000km on it. Very reliable, very smooth bike. It had a very distinct style, a wonderful exhaust note, and got nice comments everywhere it went. The only reason I sold it was to move on to my dream bike,a black 2001 Shadow Spirit 1100. I can’t overstate how excellent and reliable this bike was, definitely a great all-around motorcycle.
