Hey, no problem.
BTW, I think the manuals say 12/14psi on the tires. IMO, this is too low and may cause wheel spin in the rear tire, ripping your tube stem from the tube. I had always set mine to 25 front/ 30 rear. Never had a problem doing that. It will also help top end speed.
Here in Oklahoma, I've seen a 30deg cooler temp change overnight and it lowered the psi over 10psi.
The sticker on the bike says I believe 29 front and 30 rear, something like it I checked em this weekend.

As I recall, factory spec was more like 18psi front, 24psi rear...be forewarned, I haven't consulted the owners manual in a lo-o-o-o-o-o-o-o-o-o-o-ong time. I'm with CJ on this one, 25front/30 rear, been running those pressures since getting back into small bikes, 2 decades ago.

18 front and 21 for the rear...That's what the silver tire pressure tag on my 78 says. Should be the same for yours.
Thanks for taking the time to look that up.(y)

FWIW, I found those inflation pressures too low for road use. Bear in mind that my riding style/situation is quite a bit different than most. I'm now 99% on-road, carry a passenger ~15-20% of the time and most of the miles are accumulated at an average speed in the low 50s. If your bike is carrying less than ~150lbs, total passenger + gear, that'll have an impact. Offroad, the lower factory-recommended inflation pressure could be a plus, regardless.

my bike says its for a single rider only ;)
did you put pegs on the rear or your passenger just lift their legs up???
i guess i'll double check the sticker for the tire pressure.

The buddy peg bosses went bye-bye with the '76 model...due to politics. Earlier models had them but, the pegs were dealer-installed, as were rear racks.

Easiest means of adding pegs, to a bike with the later swingarm is via L-brackets, using the lower shock mounts...or swapping the swingarm for a K1-K4.

FYI...gvw rating, as indicated on non-US models is 220kg, approximately 480lbs.

As for the buddy pegs on my customized daily rider, look closely at the photo I posted on Sunday in the "what did you do...today" thread

Ah the best of the best...especially if you want to do a purpose-built custom.(y) The K1 is the first model to have the integrated engine cradle, welded inside the frame, meaning no possibility of stress cracks developing. It also has the rear brake cable mount, which went away during the K3 model run. And...it's not federally-required to have turn signals, a RH mirror, etc, that's all up to you, i.e. purely optional. K2 is the same but, they've rarely been seen; in my experience, they've accounted for 1%, over the last 2 decades. K1s are comparatively plentiful, second only to the staggeringly popular K0 model...which spanned 3 years(!).

IMHO, starting with a bare frame is a win-win. You get to build exactly what you want and that's one more CT70 back in action...which ought to hearten the purists, too.

Congrats, looking forward to your new project.

ok so progress on the build, I'm blasting the frame, ordered a bunch of parts, aluminum swing arm, upside down forks, rear shocks.
and yesterday i got a call to go pick up a 1 owner 1969 trail 50! awesome barn find. i think the 50 its heavier than the ct70, its a little tank!!!

Great barn find. The best thing about the motorcycle barn find is that they don't take up much room and are less likely to be scraped like a car that's in the way.
