What is typical on freeway

As for ignition, no mods, cleaned points, original coils, made sure the advancer thingy moved freely. Air filter is new after cleaning carbs
pre clean left, cleaned on right. I didn't make the insides shiny, just clean.

As for tools, I think Napa is having a sidewalk sale, they do that don't they? Gotta get a timing light to keep the washing...I mean dryer tuned up.

As for the roll over trick, yeah, I know that one, thats when I say I'm too hot and go out to the garage and sit on the bike.

Since this is a Engine forum, I will go ahead and throw an engine question in here. Is $150 a good price for a 750 engine, condition unknown? Dreaming about that 810 someday.

Seems about the time the carbs were cleaned the washer and dryer ate a few of my good shirts and some of my wifes towels.???

Napa pro 900 series compression tester $31.12
Actron Inductive timing light $55.21
Hevy Duty Isolated Base Relay $7.78
Crimp connectors 3.10
Uncle sam $5.83

$103.04 and the dryer is fixed. Now for my bike

Compression test After riding to get compression tester.
#1= 137lb #2= 126lb #3= 132lb #4=135lb

Added oil through plug holes and tried it again.
#1 =155lb #2=155lb #3=172lb #4=182lb

As far as I know your first reading is not too bad? But after oil, it shows weak rings. I would just ride it and enjoy it. As far as freeway goes, I cruise in 5th with 70 mph @ 6,000 rpms. Stockgearing (16/42) and opening the throttle it pulls cleanly up to 100+

I've played with the sprockets and finally just decided stock was a good place for my daily riding.

That brings me at exactly 5k at 70mph in 5th.

Virii, not sure about the 77 but al 650's had 16/42 stock gearing? I'm at 6,000 at 70, if your doing 5,000 at same speed your gearing is not stock?

Just finished the WG coil power mod.
Voltages Hope this turns out to look like a chart

.........before ......before......after
.........at battery...at coil.....at coil
Key off,,,,12.82,,,,,,,0,,,,,,,,,,,0
Key on,,,,12.45,,,,,,,10.48,,,,,,,12.23
ideling,,,,,12.59,,,,,,,11.00,,,,,,,12.47
rev,to,4k,,13.75,,,,,,,12.53,,,,,,,13.75

So looks like voltage to coil has improved.

On to checking timing.

I read another post after doing a search about how to time it. I tried to get the line next to the F to line up with the line on the case, things bounce around a lot so it's close. Then set 2&3 by adjusting right hand side point. It's idling a little slower now but not sure it has changed much performance wise. The advancer is moving to the 4 at 4krpm.

Well, I'm outta money, have to work 12hr shifts next 4 days so I wont be doing much with the bike.

D model 650s had different gearing if I'm remembering correctly.

Aaron, doesn't sound like yours is running too bad, but check everything over and I'm sure she'll run better.

Interesting, if so I wonder why they pumped up my gearing. Same horsepower (62) I believe, interesting. I'll have to check that out.

Yes! Keep the facts straight and be confident in your answers. Or build on the idea that she is getting flaky and forgetful. That one takes time but *ahem* I "hear" it's useful.

I'd recommend a feeler gauge while you're at it but they're dirt cheap.

I don't know. I think so. :huh: Doesn't make me want to cry, at least. If nothing else, you could get probably plenty of good parts from it if you ever need. I'm a pack rat, though and I'm always looking for some sort of good deal.


So...how is it running now that you've had more time with it?

I definately have 42, can't recall what I put up front but I *thought* I was back where I started. I've got sprockets all over the place, thought. Found that they cost next to nothing at Z1enterprises so went over the top. It was my first order and it's like a candy shop...

My X-chain and sprockets are all new and I wish I had dropped my gearing for lower rpm's on the freeway. It bothers me to be 2/3r'ds to redline. Oh well, it does pull hard!!
