Topic: Bought myself a 1980 CB900F

[spammasher]

Hi i haven't been on the site for a while been busy pulling apart a CB 900 over the last week. Really excited about cleaning it up and getting it on the road, it had been sat in a farm shed unused for over 9 years but got it cheap and it is pretty much all there. The tricky part was getting it past a curious bull inbetween the bike and the car.

Nice find spammasher! I worked on a guy's 82' CB750F SuperSport(which is essentially the same bike but w/ a lot less cc's ) and did the full tune up,including matching all the 16 valve clearances...;it had impressively smooth power delivery..and when it hit about 7000rpm..Hold On !
Shoot a good amount of some type of WD40 or PBBlaster into each spark plug hole and leave it sit for a few before you spin the engine over...it should overcome some rust that may be in the combustion chambers;it'd be good to change the oil after you do this..and before you finally go to start her up. How did the Bull take to having "his" Honda removed from His stomping grounds ??

Those were probably the best handling of the big bore superbikes, that was my second bike and the one that scared me the most the first time I opened her up having just come off a CB550K, I had no  idea of power yet. I used to dirt track the thing through corners. That or a CB1100F is still on my list of "needed".

Well even though the bull was a big boy he was probably a softy at heart, i'm just glad the bike wasn't red.

so...you had no problem with "bull" on that day ? please excuse the pun  ...I just couldn't resist No offense intended  .

I bought one of those last spring with a tad over 12,000 miles on it.Def quite a bit faster than my 750 SOHC, better suspension and brakes and handles well. My Son loves it and was cheaper that hopping up another 750 engine.I need to do fork seals and check the valves this spring,not really looking forward since I have never dealt with the round shims before. Better brush up on my math.    Glad the bull didn't get ya----

your bike looks nice, my first step is to clean the carbies and see if she fires up. Once that happens i'll concentrate on everything else. Best of luck for both of us.

The 900's were great bikes. Some say the best balanced of the DOHC's.

Here's my two. One's stock (Red) and the other is an 1125cc Ontario Moto Tech (blue) engine w/ stage II cams, Falicon crank, porting, CR33's etc.
They're great fun and always get loads of comments.

I had a 900F2 {red and white} in the 80's, almost brand new and i loved it, had a Yoshi pipe on it as well, swapped out the crap rear shocks for some Koni's and it transformed the handling as well, no more fading shocks......

Love ya bikes Delta, just a question iv'e since discovered my engine is a 900 in a 750 frame. Are most parts the same for the 750 and 900 just so i don't get to confused when i have to order things. Regards Don.

I also had someone attempting to sell me a 750 with a "900" motor.  I eventually found this 82 for $300. 

Working on paint scheme now.  I think It will be this tangerine with black stripes.

 Just about ready to put back together.

My recollection(albeit fuzzy at best) is the 750 and 900 shared most everything. Those red, white and blue color schemes are still one of my favorites....Larry

The silver and blue was my favorite.  My dad gave me a choice of a 900F and an XS1100 Standard and I said I wanted the 900F with European rear sets (an option as they called it).  He got me the XS1100 instead.  I was not complaining, I was only 15.

Nice find!!
