Wouldn't it have been something if Honda had thought about future owners say 30 years down the track and installed a removable air box so you could fit carbs to head, airboots to carbs, airbox to boots!

OK that's my wish if I ever find a genie in a bottle on the beach.
Glad to hear your carbs have sealed up, so did mine! Yippie no leaks and now I have a wheelbarrow full of parts for the carbs if they do play up.

Time we got some serious saddle time in isn't it Kit.

yup, and thank god for Spring Break, but I'm stuck in the house studying right now, despite the nice weather- I'd feel bad if I did badly on this test cuz I was playing with my bike... this is the last lab test for the last installment of Anatomy and Physiology... I need to do well.

Kit did you catch my thread on the leaking carb floats?
I'm gobsmacked that it is this easy to stuff your floats!

Frankenkit · « **Reply #282 on:** March 12, 2009, 03:58:07 PM »

...float stuffing?

Hush · « **Reply #283 on:** March 12, 2009, 11:28:42 PM »

Yeah Honda left that wee hazard in there to make sure 30 years later we were still buying floats.

Frankenkit · « **Reply #284 on:** March 13, 2009, 02:39:32 PM »

I don't have one of those.

mystic_1 · « **Reply #285 on:** March 13, 2009, 04:31:24 PM »

You have the brass floats then, or the translucent plastic ones?

All of them have their foibles.

the black plastic ones.

Hush · « **Reply #287 on:** March 13, 2009, 06:53:23 PM »

Kit are you saying you don't have that wee ledge inside your bowl?
In that case it may be a "Z" model problem only, my carbs are 1979 mechanicals even though the bike was first put on the road in 1982, a bit confusing but the Japs manufactured the PZ's then stored hundreds of them until some police force around the world ordered a dozen or so.
Some of these were not registered until 1984, now that's gonna confuse the new owner ordering parts.

Frankenkit · « **Reply #289 on:** March 19, 2009, 08:27:00 AM »

Hush, Soos, Marti-oh hell, Marti, you got this memo...
just want to check on what everyone else's cam chain tensioners look like on their 650s.
Mine is just about 1cm (1/2 in) of threaded stud sticking out the back of the head, with a nut on it. Maybe very slightly longer. Is that all there is to the 650 'automatic tensioner'? then to adjust, just loosen the nut, turn the motor over a few times manually, then tighten again?
After Mark (MLinder! Woo!) showed me how to sync my way-far-out carbs, the cam chain noise was really, very apparent, but the tensioner on this bike looks so different from all the others I wanted to make sure mine wasn't just a broken-off version of everyone else's.
Thanks!

yup,that's it....very simple,takes less then 5 minutes.....

I'll go take a pic and show you if you want... but yours sounds about right.

Too late, you're already crazy.

She took a while to tune. For some reason, she wouldn't idle. They turned her out to about 2 1/2, (I think??) and she calmed down. Then, mlinder got her dialed in pretty quickly. I took Delilah for a ride last night after the tune... WOOHOO!! That is one smooth bike now. Holy sh!t she's quick and responsive. She's never run that well before. I can't wait to get 'er out on I-5 and twist that throttle. Of course, not above the speed limit, dear.

We might want to put the windshield back on so I don't blow myself off the back of the bike, though. Just sayin'.

Frankenkit · « **Reply #294 on:** March 19, 2009, 11:28:08 AM »

Pff, "already crazy". Shut up!

Don't have my bike, or any of its parts laying around, so I got bored and decided to clean up Mickey's spare Savage carb (just one, so Savage owners can understand them) so I can throw it on FleaBay. Yay! It looks like new. 'course it IS only 8 years old.

maybe after she gets reamed?

Hush · « **Reply #297 on:** March 21, 2009, 12:40:14 AM »

About time you got your carbs synced, just ignore the loss of battery, I do....until I find a solution.

MickeyX · « **Reply #298 on:** March 21, 2009, 08:32:51 AM »

Well, we are hoping the battery situation has been rectified, so to speak.

We restarted and restarted and restarted in the process of tuning, had full lights and never a hesitation, even after she was hot, just idling or at 2000rpm for over an hour, not revving in the higher rpms to majorly charge things... she still had plenty of juice. I think Kit's fix in the switch, cleaning and dielectric grease may have done more than we thought it could. Before that, just a short run or idle for over 20 min, and she wouldn't have the oomph to start. The real test is when we just go ahead and get 'er out there for a nice long spin... I don't mind push starting but I just hope we are near a downhill cuz she's a heavy mofo.

Now, we need some specifics of how to adjust the cam chain tensioner... which I'm sure, while I was at work, Kit has been studying up on and getting your advice here. Just a little sound out of it that needs to get adjusted and she should be ready to rock for the season. It will be the 1st time in 3? yrs of ownership that she will have a reasonably reliable bike. I guess I better get my butt moving on figuring out how to carry our camping equipment for some adventures...

I swear thats what did it for me.
Cleaning contacts, switches and connectors is a boon for the electrics.
I went through EVERY connector(spade, bullet, and the multi pin connectors) both the male and female halves, sanded and coated them with di-electric grease.
Mabey it was that or a (lower?) different current draw due to the dyna 2000 I put on my bike.

And BTW, the 650's I've dealt with, syncing the carbs really assists in ease of starting them quite a bit as well.
Not to mention a more even, and a lower idle RPM is tolerated without killing the bike.
Acceleration benefits a bit as well.
One of the MUST do's IMO for general tuneups.

Yeah, these 650's are really a kick in the pants if you ride them in the RPM range they make good power in MickeyX.

L8r, Glad tyo hear Mlinder was able to help you synch the carbs!

Oh, BTW, a little cam chain noise is not unusual, just go by what your manual says, and it should be good.
