0:05 NEVER do this! Touch the cylinderhead over the sparkplug instead and avoid getting burned

How do you do the calculation is berry inportant explain on the video

I had a 125 cc version in England in 1965 . I don’t know why the American version was never fitted with indicators .

Nice,, 👍👍,

Nice bike

👍🏻😀

รถในฝันครับผม

I had a new white 1964 exactly like this. A friend of mine just back from Vietnam had a Honda 250 scrambler. He and I drove from Burbank up 395 to Oregon then to the Pacific coast then down thru S.F. to Burbank again. At Lake Tahoe we met two girls who had driven Honda 50's from Saskatchewan Note that mine and this one that it did not come with turn signals! You had to hand signal! So night driving was dangerous. The Roman helmet front fender cracked at the front tip on all of these. The common solution was to drill a hole ahead of the crack. If you have one of these NOT cracked yet put JB weld or Bondo under the front tip of the fender to reinforce it. Keep the cam chain properly adjusted. This was another weak point. Recommended oil change is 500 miles. Get a magnetic drain plug and clean the centrifugal oil filter. It cakes up with impurities. When my car broke down that motorcycle still made it possible to attend college and my part time job. I loved this bike.

How many cc,and doesnt it have electric start ,you lose horse power with that single crabs ,but the dreams never were fast ,scrambles better power.

What kind of battery do you have in this? I understand it is 6v. Havent had the best of luck finding one for mine. Wisco JA-3?

I have been locked out of this account for years, so sorry for the delayed response. @eduki - I don't know if it is the same for a CB1100F. My bike was a 1981 CB900C, I think it is the same for the CB1000C. You need to measure ALL of them and record your values. There is a spreadsheet in an old yahoo forum for CB900C/CB1000C where you record your values and it tells you what shims to remove, move, or keep. I removed the ones I didn't need, went to the Honda dealer and they just swapped them for the ones that I needed. The spreadsheet is called __Valve_Shims_Tool_New-n-Improved.xls @GREG GERHARDT - This is a video for folks that are trying to fix their bikes. You can also measure in inches (and I am in America). I do get it. The video and sound quality is not good because I just had my son hit record while I did it. This bike was sold MANY years ago so I can't recreate it and edit. Yes, I worked in a shop with ghosts ;-)

Excuse me if i´m wrong... you measure one of the shims, but then replace the other? i don´t understand...

Not for the CB1100F? Thanks! ;)

I learned to ride & got my motorcycle endorsement on a bike just like yours!!(Figure 8's, hand signals & all that...!) I loved that bike!

Sound is camera constantly trying to focus. Chill everyone.

Dude what's that at sound in your video, you got some paranormal activity going down

It's called a feeler gauge and you be should be measuring them in hundreds of a millimeter. God some people just don't get it.

how fast does it go i see one on cl for around 2000 and can you pop wheelies on it without modding it?

what in god's name is that noise?

HELP !!! I stupidly removed both at the same time, I cannot get the tool to compress both buckets, it slips off one and doesn't allow room for the shim, any ideas on how I can get them both compressed evenly?!

Congratz

do you know where to locate the VIN on this bike

I know this is a old video but what size are the shims like diameter

My cousin had a blue CA 195 in 1971 , similar bars as well ! great memories ! :o) thanks for sharing .

anyone know where the chassis number is on these bikes? I've one..but its painted over...

Its called a feeler gauge stupid!

buckets .....haha lol... ya avent a clu..

I bought an old '81 CB900c and didn't have a clue. Thanks to you,..I got thru this step with flying colors and carb rebuilds thru the Honda forum. Thanx for your help.

mesure lower part of cam bottom center of base circle on all vale in bucket cam on top engines from supras with 7mge to a old honda Ferrari what ever verey simple ,,,,,eng is not my first language

Love the vid. Only thing confusing is in the vid you are measuring exhaust on cylinder 4, and the engine is in the b position or 6 oclock, Your cam lob is facing up. if you do the same thing on my at pos b and at 6 oclock. my cam lobe doesnt face up?

I would always adhere to what the manual says. You hear all sorts of eerie things out there, like changing exhaust does not lean out the mixture or just hand tight the spark plugs... I guess who ever designed the engine knows best.

Great tutorial. I stumbled here trying to find what the clearances are suppose to be as I have a compression issue and I'm rebuilding the engine entirely after buying it recently. I have seen different tolerances floating all over different forums and such, but the manual actually states different tolerances for each of the different valves... I am going to use your tolerances, as I've seen them elsewhere as well. Thanks again. Cheers!

I agree. I don't use them anymore. They are a PITA.

It's not that hard, although I don't find gripping soap in the shower difficult either. I did assume the viewer has a basic understanding of life. Obviously, my bad.

Yeah, I just had my 16 year old press play and hold it for me. I just couldn't find anything like this so I made one my self. I'm glad it helped SOMEBODY

yeah, that's not true. even the "earlies" had enclosed drive chains.

I think i have the same problem with my 81 cb900c :(

awesome vid, i've got a 1981 cb900 that i've done the valves on 3 times now

i have n 82 cb900c, it runs and starts right up but it seems to only rev and run right when the choke is pulled. If i let the bike warm up it will stay running and idle without the choke pulled but if i try and rev the motor it will sort of backfire as its climbing in rpms and it will sometimes climb back down in rpms slowly, any ideas?

For real. I almost stopped watching, but this is exactly what I need to do with my 900F.

everything looks good ... except you wearing latex gloves??? Man up ... lol.

im on that yahoo group ill have to go check that out and thxs

Then you go and rip the hard drive out from your sisters computer ( your dad's one will also work) strip it down and remove the super magnet, tie a piece of string through one of the mounting holes and through a tennis-ball, stick the magnet to something metal in plain sight in the garage and you will have no excuse not to use it next time to recover the shims, ok and say sorry to your sister for killing her pc, still you can take her for a ride to cheer her up or get another hard disk ...

Using a powerful computer magnet to remove the shim is not just a gimmick, shims are super hard steel and gripping them with pliers is like squeezing a bar of soap in the shower. It's just a matter of time before the thing shoots out of your grip. the danger is it dropping down into the engine!!! Not good.. so what do you do then?? strip down the engine? turn the bike upside down and shake it? no you use an extending magnet and poke about down there and hopefully get it back, step one

most people have the cheap little screwdrivers laying around and they work great. if you have the fancy magnet thing, use it.

they are all over eBay. just search for "cb900 valve shim tool" or whatever model you have

just the ones that need replacing. it helps to take out the ones that are out of tolerance and set them aside. you may be able to reuse them. i used the fancy spreadsheet found on the cb900/1000 users website to see what I needed. i reused a couple and needed a couple.
