Anyhoo, while I can't see any reason not to go for the Cheng Shits as endorsed by Z3N, there's always the ubiquitous Distanzia?

I'm pretty sure my TY has a CS trial on the back and the Pirelli trial tyre on the front - no problems with that on the road, although we're only talking maybe 16hp here.

The reasoning behind trials tires is so I can still have sufficient traction on loam and packed dirt while still retaining some traction on the potholed streets of San Francisco. I cut through the park pretty often too. I heard some good things about IRC but CS seems like the best bang for buck option.

I haven't had any problem with my Cheng Shing tires and they've been through a lot. Mud, water, ice and a gravel they're like the all-season of bike tires. Honestly I feel like unless you've really done some work an old bike is going to be let down by its suspension well before the tires become an issue.

Just installed new points, condensers, and new plugs. I'll pop the plugs and take some pics.

Edit for more info:

Bike used to be super cold blooded until I did a valve adjustment. Now it fires up immediately but I have to ride it a few miles at 1/2 choke before I can get it to idle without stalling.

The bike bogs terribly on initial acceleration. I suspect the accelerator pump is clogged.

It's not stalling or anything, it's just missing here and there at idle and low RPM's.

Wow, I can't believe I've ignored this bike for this long. Then again it is still in the drat 30's in Michigan. Anyway, I managed to break the choke cable when I was getting it ready for winter storage and my spark plug caps are the originals and they fell apart when I looked at them wrong. Anyone have any idea what I should use to replace the caps? I should probably replace the wires too but I'm pretty sure the wires aren't removable from the coil. Any ideas?

Tried to install a new choke cable on the CB750K. What the gently caress??? I got the broken one off real easy. I hosed around for two hours trying to get the new one into the carb. I seriously have no idea how to get it on. I'm tempted to pull the god drat carbs to re-connect it. If I do that, then I might as well clean the carbs while they are disconnected.

I feel a little like York in that I'm having a conversation with Zach in this thread, but I figured out why the Choke cable was so hard to install... the previous owner had crimped the cable stay for some reason. Once I bent it back to the original configuration, it was able to get it in just fine.

Guys,

A friend of mine posted this link up in another part of the site - so you may have seen it already.

Last year a good friend (George) and I rebuilt a couple of Honda CB750's (a 74 K and a 76F) and went on a 13,000 mile 70 day trip around the united states. By around I mean a pretty complete circumnavigation. We were pestered by a few of our film friends to document the entire trip. So we did. We're finally getting around to putting it on the intartubes.

Whoah, looks like I missed this response. I am on sohc4 and their advice has been pretty good. I should go ask them what I should do to replace my plug wires. (Splice into existing wires at the coil or upgrade the ignition system)

As much as I would like to turn my bike into a cafe racer I really don't have the free time to devote to the project. Plus it was my dad's bike. His soul is probably restless from the minor things I did to it. (Remove sissy bar, windshield, engine guards, etc.)

As it was...

I think it looks nice. I'd look into getting a decent set of shocks and at least changing out the fork oil. Maybe consider dropping the forks in the triples a bit.

Can't you change out the plug wire just by disconnecting it from the coil?

It looks like the wires are permanently attached to the coils as far as I can tell. The shocks do suck. How cheap can I be in regards to a set of replacements?

There are sets of pretty generic "old bike" shocks/springs available from most suppliers. They're generally a black body, chrome progressive spring setup. Very popular among the old Kawasaki owners. They're about $100 a set. I have some on my bike and I've been nothing but pleased. One caveat: they are stiff as hell and if your bike isn't very heavy they're pretty harsh. Great handling though even if your spine turns to jello.

When I lowered my CX500 (About an inch in the triples up front and about an 1.25 inches in the rear with VT750 shocks) it really improved the geometry for the better. It went from lovely cruiser with clubman bars to sort of agressive stanced not so terrible handling not so street bike.

I would see what the SOHC guys do. I was talking about dropping the forks in the triples just a bit. It'd make the bike turn in a bit better but it would give up some stability. It may be the totally wrong thing to do w/ that bike though.

The stock coils have the wire molded in. It's not detachable.
I've got a set of dyna 3ohm's for sale though if you're interested.
As for shocks, I wouldn't go with the cheapo ones. you might as well have a hardtail at that point. I'd say find a good set of stockers or get progressive rears.
Or even better... Ohlins

negative.
It doesn't turn better at all after dropping an inch. But, a tapered roller steering stem bearing will make the bike feel a hell of a lot lighter.
Although... if you can get a 750F swingarm on there it's a bit more stable at speed. (just beware the offset and space your rear wheel and sprocket accordingly)

You'll be lucky to get >25mpg out of any RD and that puts the range at about 65 miles given the teeny tank they have. They are generally reliable enough, except when you're waiting for some hippy to send you a new regulator.

and those won't work too well on stock coils.

My friend has a very nicely set up one that gets around 50mpg. He can do 100 miles on his no problem. He's also the original owner of his and has taken very good care of it as well as upgrading the weak spots. If you'd like I can find out what mods he's running on it.

The old yamaha two strokes really are great for reliability though. Nothing like stopping in at some random redneck hardware store and filling up the oil reservoir on my YDS3 with straight 30 in a pinch. Nothing blows more smoke than straight 30.

Considering what the RD was designed to run on you really don't need fancy premix. I did a little searching around and apparently some people get 35mpg+ on their bikes. I do a lot of short trips on mine, which is the worst for mpg. They're a terrible budget bike regardless because the market is pretty hot for them right now.

I'll admit I have a sweet 76' KZ650 for most rides because between the 2T oil and gas you're pretty much always stopping to fill old two strokes with some sort of fluid on any decent sized trip.

New(er) shocks and coils on the way courtesy of GnarlyCharlie4u! I tested the current rear shocks last night and the back end just bounced with barely any effort. I guess that's not good. My R6's suspension is hard as gently caress but that's due to the previous owner being a lard rear end and my theory of not loving with the 20 different suspension settings.

Here's to hoping that the new shocks take care of handling issues and the coils take care of it running rough.

When I got my KZ650 the shocks were like bed springs. The pistons were hosed and the springs were destroyed enough that I bounce the rear of the bike up and down with two fingers. Previous owner was a farmer and fancied the KZ as a redneck dualsport.

Morons! I have morons on my payroll!

I posted the short version of the coil install in another thread, but I'll post the full story here. The coil install is really quite straight forward. I had some extra wire and electrical connectors so I could leave the old coils and wiring as is (in case something didn't work or whatever.) The screws holding the coils in didn't want to move so I soaked them in O-Ring destroying WD-40 and went at them with my Harbor Freight impact driver. Of course it didn't come with any instructions so I just hammered away for all I was worth and I may have been tightening them for all I know. Anyway, I managed to get them off without completely stripping them.

I wanted to make sure the coils worked and GnarlyCharlie4u was nice enough to throw in some plug wires. Unfortunately I have threaded ends on my plugs and not a solid post. So I made a trip to the local AutoZone to see if they had any plugs and maybe wires for my bike. I was optimistic when I saw a 1975 Honda CB750 parked out front:




Sure enough, the bike was owned by an employee who had recently done a dynacoil replacement as well. He was extremely helpful. They didn't have my plugs so I just bought the cheapest set of NGK's with removable posts and a set of make your own plug wires. In hind sight I realize I should have bought a crimp tool too. Oh well, live and learn.

What followed was a comedy of me trying to make plug wires that would plug in and stay into the coils. The coil side boots that came with my wires just weren't going to work so I used the boots from the wires that came with the coils. The metal connector seems slightly longer than the ones that were on the old wires so I'm not sure how well they will stay on there.

Bike fired right up and sounded great! No more miss at idle, throttle response was improved, and no popping from the exhaust! It was 10:00 PM when I was done and I know better than to go out for test ride at night. I mean, murphy's law dictates that it would definitely break down then!

I may use electrical tape and wrap the gently caress out of the coil side connectors to make sure the drat wires don't fall out. They seem pretty good in there but I'd rather not have them vibrate loose.
