    Skipping sparks, not running smooth on stationair

    Seems that I remember 2 or 3 ohm primaries and 12k ohm secondaries. Only go non-resistor if using resistor plugs. You need 5k at the end (plug OR cap) to reduce radio interference. I think only allowed no resistor on race bikes.

    Skipping sparks, not running smooth on stationair

    There should be a 5k Ohm resistor in each cap, - OR- a 5k Ohm plug - not both! The resistors in the caps some times fail, often just from corrosion of the resistors or contacts. If you run the resistor plugs (the fancy iridiums are most all resistor), make sure no resistors in the caps (you can...

    Carbon build up question

    I would use brass or mild steel. Don't use and abrasive one, or a plaxtic one as most contain abrasives in the plastic. But, even then if you only clean the flat side with it you should be Ok. Clean the stem/seat side on brass or steel. And, you just need to knock the carbon off which should not...

    Skipping sparks, not running smooth on stationair

    I have experienced this with a rough point cam. Is there any roughness, rust, hardened build-up on yours?

    No Accelerator Pump

    Did you align everything before tightening down to the cross-stays? All plates have to be fully closed before (and after) tightening the carbs to the stays. Otherwise, one closed throttle plate can hold the others open. Then the choke cam should be checked to make sure throttle plates close off...

    750 disk brake upgrade

    The original rears should be more than enough to progressively lock up if in proper repair. Depending on the model, dual caliper front ends can "drop in" from such as GL1000. Dual piston setups have also been used. More important is getting the original system optimized (braided lines, well...

    Crankshaft Broken Teeth

    Keep your eyes open. I have seen bikes go for $100 at times, and personally bought a '79 CB750F for $250 a couple years ago. Plus, breakers regularly list engine parts.

    New member with caliper question

    Don't know if it is the corrrect caliper, but there is a solution to the bleed screw. A kit is available (many parts stores, plus Amazon) with a brass replacement seat and steel bleeder. You dill out and tap the old corrupted hole to 1/8" IPT, clean the swarf out thoroughly, and install the...

    Shipping a Motorcycle

    Consider buying local. There are South American manufacturers with decent bikes and better local parts availability. One of my students lived in Bogota as a medical equipment service engineer and sad that the bike was the easiest way to get to job sites in their traffic.

    Rare Find

    Cracked side covers are easily repaired with ABS plumbing cement. If you can't find it locally, Amazon. Reinforce with fiberglass cloth on the inside. Remove paint from the area first. Clear all-purpose cleaner does a good prep, but keep it off paint you want to preserve.

    pinstripe removal

    Great! And thanks for the follow-up. BTW, I removed pinstriper-painted names from the tourpack of a GoldWing SEi with EasyOff oven cleaner and Qtips, then a final polish and buff. These methods work well if the decoration has not been sealed in with clearcoat.

    Master Cylinder

    Patience, heat, screwdrivers for wedging and levers. Did I mention patience? And when you get it off, don't bypass cleaning the "spluge" hole - tiny hole in the bottom that releases pressure when you release the lever. Otherwise, the brakes will stay locked. I use a piece of high "E" string from...

    Brake master cylinder, rebuild or replace?

    You usually need to bleed the MC by itself by holding a gloved thumb over the output until it is pumping fluid well, then quickly hooking up the banjo. Messy, but I've found it often necessary. Lost of protective plastic and paper towels for absorbing. Isopropyl alcohol works well to clean it...

    Brake master cylinder, rebuild or replace?

    Locking up is usually caused by the tiny hole (some call it spluge hole) in the MC. I clean them with a high "E" electric guitar string chucked in a pin vice. Ancient collapsed lines can also cause it.

    Repairing side cover on a '79 CB750L

    When grommets get hard, replace them or plan on replacing the covers due to being lost by the side of the road. Lanyards are a good idea over the often-lost left side battery cover.

    '79 CB750F Super Sport -- Carburator Rebuild Kit

    Looking good. Remember to rig a test bottle and leak check them before re-installing. I use isopropyl alcohol because it has less smell, is safer, and if any doesn't drain out it will mix and burn,

    Handlebars cocked slightly to the left

    Could be: bent forks, bent handlebar, or most likely the tubes are not lined up correctly in the triple clamps. Support the front of the bike with a jack, hold the front wheel from twisting, loosen the clamps and correct. Much easier with two people. Observe correct torque specs when...

    Anyone tried "Niche" batteries?

    I'd put the Yuasa in a BMW. Have had great luck with them in GL1800s.

    Let's see your other bikes

    I just finished this '78 GL1000 fencerow rescue. I call it Johnny 5, because it is my fifth GL1000 (if you count the junker I bought last year for parts). Plenty of PO issues, but I'm pretty pleased how it turned out. Before and after photos:

    Used 1981 CB750c $175

    I bought a very trashed '79 CB750F last year for $250 and spent the winter fixing PO issues and the fact that it had been parked outside (last tagged) since '99. Made a nice rat bike out of it and sold it last spring for what I had total invested. Kept me busy over the winter.

    Compatible forks

    I used a set of '78 GL1000 forks on my '79 CB750F build. Used GL1000 triples, axle and headlight ears, jury-rigged gauge mount and the brake calipers swapped right over.

    Brake master cylinder, rebuild or replace?

    I've used Chinabay MCs, and found that they must be disassembled, cleaned thoroughly, and reassembled properly with brake fluid lubing the assembly. Don't be surprised at the stuff that comes out when you clean.

    A little rant

    As indicated by my OP, I have been attempting to help - plus provide links to where they can help themselves. I have provided links to pdf copies of FSM, and then have the questioner admit after many trouble-shooting steps that they had not read the FSM for that issue, and finally end up finding...

    A little rant

    Sorry for this, but it seems way too prevalent these days. Someone asks a question on a forum that they could have answered themselves with a two-minute Google search, FSM search, or a look at the parts fische easily found on a dozen different dealer's web sites (I prefer Southern Powersports...
