Hehehe. I ordered her a brand new black fuel tank as a b'day/xmas gift. Should be here in a week or so...  ;D No goo inside, no dings, no gunk from welding, no worries about rust working it's way through... now she can have the original one to mess with and make a rat bike version. She's been wanting to experiment with it but it was the only one she had. Now... I have no idea what she is going to end up with.  8)

There's always room to be surprised with short shocks! ;) just sayin'... ;)

I helped her pick out the tank- it's going to have the original 'drive with caution' etc sticker on it, like it was new. :D  Details, right? ;)
Was going to go out yesterday and re-run my fuel line to see if that clears up the weird throttle response (full wrist to go 15 in first, accelerates in fits and starts)  and I need to figure out how to smooth the throttle response/where to position my clutch, because it seems like unless I start out just baaarely rolling, I get jerked almost half off my seat! Probably just rider error (I learned on a 125cc... big difference) but I'm convinced some of it has to do with clutch/throttle adjustment, too. 

...and I'm lookin' at short shocks, because the CG is so effing high for me, it feels like trying to dance with a fat girl... wondering if it gets better as it gets lower?

Awww crud... I just got a call that the tank is discontinued. It showed on the site that they have them... They have a new part # for the newer stock so that is what I picked. Bummed out.  :-\ I have no idea if we can locate a new one or not. That was 1 of 2 sites I could still find them available and the other one was a lot more $$$.

Kit just sighed and said... "well, now we can get the shorty shocks and new coils..."

Isn't she just priceless? Gotta love a woman who thinks that way.  ;D

Hey D.R. long time no see/hear...whateva. ;D
My bro-inlaw has exactly the same model as Kits and is selling it plus all his spare CX parts, shame the USA is so far or I'd have a pretty fresh tank for Kits to play with.
He just scored a 79 CB650 and an 82 Custom so wants to clear his shed.
Wonder if I have enough room in the shed for a CX? nah Jaffa would surely kill me. ;D

Just scoped that tank D.R., same as my Custom so probably no good for Kits as hers is a 650CX I think.

Hush! What does it say in the title?! *points* CB650C! 

But yeah, the nighthawk was an SC and the tank wouldn't work.  :-\  I'm kinda ok with having this tank, I guess.  I can be punk as I wanna be, just paint this one anyway once it gets warm enough to shoot.
Today and tomorrow I need to focus on finals.

wtf am I doing here? 
oh yes, meditating, calming and preparing.  (sounds plausible, right?) ;)

You guys are cool.  :D Yeah, her tank isn't a total waste or anything so it will last her quite a while yet. (it has to) So, we went ahead and ordered the shorty shocks and are looking at different coils. Not stock, apparently those suck. The big question for us is do we go slightly higher or lower on resistance from the OEM? Is there anything else to consider on picking aftermarket coils? I don't know much about them. I need to read up on the technicals and finally use that electronics degree. (it's about time  ::))

Any idea where I can get the seat trim in this picture?



I had my lovely, sexy, beautimus seat redone and part of the problem with the PO losing the grab bar was that the guy started using the SEAT as the grab bar, and mangled my chrome seat trim to the point that the seat recoverer couldn't.... recover it.  It APPEARED to be a chrome metal strip held on by tacks or something that were poked through the vinyl.

Yup you described it pretty well Kits, I think I have seen the Cafe makers on this site talking about adding just such trim to their seats so it is a definate possibility for you to redo yours.
Can't recall the forum thread but I know it was Cafe's they were doing.

Well, as you can see in the BOTM thread, she got the new-to-her tank on. She really made that thing shine. I had no idea that was under the layer of crud we bought.  ;D

In other semi-related news...
We've been having to work on Kit's bike out in the community carport area all this time. Dragging tools in and out, worrying that if we walk away for a few minutes, some a-hole will come along and steal stuff. (has happened). Then there is the stray cat who keeps "marking" his territory all over our tires and 2 different bike covers of Kit's. (2 cuz some a-hole stole the first one) Went outside yesterday to find the cat had pissed all over Kit's brand new cover.  >:( (It was all over my one hand.) I've repeatedly gone into the office to get them to put some humane traps out here to catch him. They keep saying they will, but nothing has ever been done. I've asked nicely for a while now about getting one of the garages here. The manager never gets back to us, ever. So a week ago, Kit found her and asked her again, face to face. She told her that there aren't any available so we are on a wait list. Yesterday, the cat thing hit once again and I had enough messing around with this. We are either getting a garage where we live or I will go rent one somewhere else. I don't care who gets the $$ but it was gonna happen this weekend. Kit deserves a garage, dammit.
Kit stayed in the car (smart woman there  ::)) and I went in the office. I let loose on the one that was there, let her know we keep getting stuff stolen, pissed on (do ya think when I put my pissed-on fingers right up to her nose, it made a difference?), we've had someone back over mine and knock it on its right side (replaced muffler on that one)... on top of all that, I also let her know that our dishwasher hasn't worked for the 1.5 yrs we've lived here and the manager keeps sending the guy who knows nothing about that stuff so he does nothing. And why, by the way, do I keep having to come back in there over and over for the same things anyway?  >:( (the last time I blew my stack at them like this, we had a brand new stove/oven the next day  ;))

She apologizes and tells me there is a garage right next to our building that has been open for a while.  ??? She had no explanation on why we were put on a waiting list. I told her that I'm gonna go wash my hands in her bathroom, run our errands (Kit's throttle cable and plug wires came in.  ;D) and in the meantime, I want her to personally walk over there, open it up and make sure it is ready. We came back in about 2 hrs and she has the keys waiting for us. Kit loved it immediately. It's deep enough that we can fit both bikes in and put a car behind if needed. We put the cycles in right away and started loading our stuff in last night. We built and put her new plug wires and caps on last night. Will try to do the shocks tonight after she gets home from work. Getting it up on the center stand is rough.

Some other very good things happened in all of this, the one neighbor noticed we finally got a garage, we got to talking cuz she's had a lot of problems with the one manager too. I found out that miss manager has been asked to step down because of too many complaints. On top of that, I scored us some Elk steaks from the neighbor. hehe. They were good. We are having the rest tonight.  8)
Alright, off to play mechanic on my own bike for once until Kit gets home from work.

Good for you Mickey you go girl! ;D
Score big time on the garage, I'm spoilt with a 30foot by 20 foot double garage to play in, but I had to wait 34 years to get it. ;)
I want (no demand) photos of the fitted shorties when they are on as I'm considering this option on one of my bikes.
Kits, go cook the girl some steaks....she deserves it. ;D

lol hooo hahaha
well
I have a great chick here.  She's dangerous when p!ssed off, fortunately I'm rarely the target. ;D
ASIDE from all that... I... uh... need to take off the rear part of the exhausts to put the shocks on, so instead I installed my new spark plug wires and caps.  Tonight the new spark plugs go in.  I used Hondaman's suggestion for low-rpm, low distance riding, and got D7EA, figuring with the extra heat they'll stay just a little cleaner, considering the way I normally ride. 

If I have enough energy left (work kinda takes it out of me...) I'll pull the carbs and give them a good once-over.  I need to re-route the throttle cables anyway (glad I finally have a cable routing diagram!) so it's not far 'out of my way'.

God, it felt good to go for a little ride yesterday, even if it was in the parking lot, on 3 cyl. and I ran out of gas cuz I forgot how very, very little I put in.  ::) ;D  That was a great laugh, though.   :D

Er hang on I did same last week, hangs head in shame.
No fool like an old fool. ;D
You sure you can't remove the old shocks without removing the mufflers, its just that the more these pipes get moved, the more they leak or damage.
Anyhow I waaaaant piccies when they done right! >:(

yes, yes, pics.  The pipes are in two pieces, the headers, then 'the rest' so seeing as I loosen 'the rest' way up to install the headers, it shouldn't be that hard nor detrimental to remove, but I'll see.

Hey! Hush! I know you're reading!

MickeyX and I put the shorty shocks on tonight. It was... interesting.  My exhaust hangs juuuust so, right in front of the bolt through the clevis, so we put a 2x6 under the rear wheel, undid the top, then turned the wheel to spin the board out.  That lowered the swingarm until we could reach the bolts thru the clevis.  That went ok... then we ran a pair of 2x6es under the wheel again and buttoned up the eyes.
 We used the bolts from the rear of the grab bar (I used 13mm bolts, probably 2+ inches long) with a socket and a 13mm nut on the other side of the socket (bolt thru metal sleeve, thru socket, nut) tightened the nut down until it had a good grip on the bolt, then pulled on the socket/nut combo, pulling the metal sleeve right through the rubber bushing. 

I went through all that instead of re-using the original rubber bushings because I figured the new, albeit tight, bushings would be an improvement.     

Used one washer in stead of two  at each clevis.  Since everyone says the shocks tend to toe in, I stuck the washers on the inner side of the clevis and left it at that.  Two weren't going to fit very well.

Adjusted the preload to one less than the min.  I'll see how that feels.  Bike doesn't have the same 'plop into a lazyboy' kind of feel, but it feels good.  I can flat-foot and bend my knees, and from there, I can actually really walk my bike around, lean from side to side and feel much more centered in general.  I wished I could've taken her for a ride, but the carbs still need a cleaning.  :P

Still need to 'kiss' the chain guard with a hammer or something because the new shocks touch it.  :P

Haven't tried lowering the front yet.  We'll see how that goes.

Ooh, er, yes. pics. Well... I went out to the garage, then realized I forgot my camera, then took off my carbs.  I can mock up the tank and seat for you later today, though, if you don't mind the bike's guts missing... :D

I was right, 4's slow jet was completely clogged... seeing more of the mystery 'gel' in the float bowls. ??? It looks like a gel, but when I get it on my finger, it feels more like a gritty paste.  Most of it seems to be rust-oriented.  >:( I realized my throttle pump tab gap was way out of spec (thanks whoever mentioned that)  so I bent it down... my choke throttle adjuster needed adjustment, too.  All that is well and good, but... the throttle pump squirters for 1 and 2 are clogged also! ARRRRGGGGHHHHH!!!

So today I'm gettin' down to business after I do some studying for the test next Tues.

In Hush's fashion,
"Dear Diary..."


I hate carb work.  I hate it, I hate it, I hate it.
I spent ALL DAY playing with my carbs. 

More of that gel/white powder/sand crap. What gives?  Unracked the beasts, cleaned the throttle pump tubes, air passages, gas passages, the whole deal with full orchestration.  Took out the air cutoff diaphragms (Hush, I'm not sure if your model has them, but they're on the side, a two-screw plate with a spring (surprise!) and diaphragm... oh and a little flat o-ring, don't lose it...)   Most were pinholed.  As I don't anticipate honestly going more than 3 months (or 300 mi) without having to do this again, I conducted an experimental procedure, in which I used NAPA's plasti-dip (the thin spray kind) on a cotton swab to paint over the pinholes and cover them up.  Considering they were pinholed anyway, either I will have greatly improved performance, or nothing noticeable.  Either way I'm not sure it could be worse off for my experimentation. 

Does anyone else have massive problems with trying to get the (godd@mned!)  choke plates to not bind when screwing on the big ol' support plate for the front?  It took me an hour to get them to not bind... and I'm still not thrilled with their performance, but at least they're smooth and snap back like they're supposed to.

So, after 10 hours of carb work, I had to call it quits at the end of the evening just before mounting the carbs.  I'd forgotten exactly how my service manual said to route everything and I want to have it right.

Besides, I have school early in the morning and all day, blah, blah blah.

MickeyX helped me out by gapping my new spark plugs and installing my battery tender cable.  Yes! With the new garage comes power! With power comes battery maintenance!

I'm excited to see how she runs with all the stuff I've done.

oh, and Hush, didn't say it yesterday, but I had to take a hammer and beat the crap out of alter my chainguard.  I was going to run w/o the chainguard, but I like the stock look, and I also like my legs/limbs/etc the way they are.  Just need to push it 'in' about 5-10 cm, because the shorty shocks want to rub.

For a future reference, to keep carbs clean, run Shell gas.  Not the cheap stuff like racetrack.  Cranked my carbed yammy up (they lived for being varnished) and it started right up, rpms were 3.5k on choke, dropped to 1k and stayed there with choke off.  I had not started this bike in over 4 months.  I have let it sit longer with the same results.

Oh, don't forget seafoam twice a year.

I got really tired of cleaning those carbs every few months (not a pretty job on these), this stopped it completely.  Been like this for over two years, it has proven it self to me.
I don't have a motorcycle, sold it ('85 Yamaha Venture Royale).  Haven't had a CB750 for over 40 years.

I'd actually had better luck with Chevron than Shell, but the problem was this cr@p from the old tank...flakes of rust and probably degraded liner.  The guy who 'professionally' lined my tank was a damn hack.
