1970 Honda CL450 Scrambler

Just starting on the next project - a 1970 CL450 Scrambler. Another bike I've owned for about 25 years that has been sitting in a garage here and there.

Before any clean-up -





Looks like the chrome will polish-up pretty well -



Gonna need tires and a few additional parts. The tank is varnished inside, but not rusted. Compression is good. 16,000 mi, After a good bath the carbs will need to come off and be ultrasonic cleaned and rebuilt. New seat cover, paint, and decals among other things.

memories of my blue cb450 [with dunstall megaphones].. with torsion bar valve control [needs good oil supply].. beautiful engine casting imo, with quality chrome responding well to goddards glo and that touch of fanaticism [which you have already achieved].. torsion bar torque after almost 50yrs could be a factor, ie, if you intend to ride this one...

Because these tires are shot and will be replaced, this one will be ridden when completed.

The CL got its first bath in about 25 or 30 years -






Carb and petcock kits are here, so the carbs will come off and get cleaned and rebuilt. Last time it ran (20+ years ago), it was running on only one 1 cylinder. Hopefully a carb cleaning and new plugs will solve that. Probably check the points too.

Please take as many photos and show your progress. Love these bike restorations.
Good luck with the rebuild.

OMG!! I bought one just like this one in the 80's, for about 600 bucks. It was a 1970 model but stamped manufactured in '69. In about the same condition too. I rebuilt the carbs, replaced other small parts like the rectifier and exhaust gaskets, new tires, battery and it ran like new! I ended up trading it for a new '91 Honda 750 Nighhawk lol. Thanks for the memories!

Here are some of the photos that were lost to the Photofuckit debacle -

Before anything -





After a good wash -






Update 7/21/17 -

Cleaned and rebuilt the carbs, new plugs, set the points - and it fired right up!

Last time it ran was probably 20 years ago.

Electric starer was spinning, but not engaging so I kicked it over. Took about 4 or 5 kicks to fire up. Ran really well - idled smoothly and no smoke at all.

My 17 year old son was helping me. Last time it ran he wasn't even a twinkle...

Thanks. Still have a long way to go to get it where I want it (VG, but not quite EX cond).

I wanted to confirm that the engine didn't have any major issues before spending any amount of time and money on it.

Looks like I'm good to go.

Beautiful. Boy, does seeing that take me back. Honda Scramblers were the first bikes I really lusted after on the cusp of getting my license.
