    Which thread repair?

    Heli-coil and the like seem to get a bad rep... but I always take it with a grain of salt as usually the guy telling me the thread repair is CRAP, is the guy that just galled all the thread off his sparkplug or drain plug. Thread inserts were not originally designed as thread repair. A properly...

    Barrels pistons rings questions... 1978 GS750

    You have a picture of you measuring a piston, just under the rings, in line with the pin, with a caliper. That measurement means nothing. To measure the piston, use a micrometer. A caliper is not accurate enough. Measure the piston at the SKIRT, in three directions, start at 90 degrees from the...

    Recommend a good tap and die set

    R&N, Union Butterfield or my fav SKF/DORMER (not US made... but neither am I) An industrial supplier will have a house brand, made in asia, and a decent brand, NOT made is asia... BUY THE DECENT BRAND. ... and you probably don't need a " set". Buy #1, 2 and 3 taps in the sizes you NEED. You...

    Oil Filter Stud thread repair

    E-Z LOK thread insert M6x1.0 ID Drill 8.6mm (0.339") and tap to M10x1.5 They come in two lengths or you could drill it out and install a plug.... I would probably weld it up and drill and tap a new hole

    r/r questions: how to find out if r/r is series or shunt?

    As close to the battery as you can. I usually go directly to the battery. The new R/Rs don't pull much power.

    Rotella T4,T5, or T6?

    T4 is OK if you have a roller bottom end If you don't have a roller bottom end, buy motorcycle oil. Rotella is NOT good oil, Rotella is CHEAP oil... and the reason you wanted Rotella was higher levels of ZDDP or Zinc dialkyldithiophosphates, and Rotella was reformulated a couple of years ago...

    1979 GS1000 Oil control problem

    If it's valve seals, you'll get a puff of smoke after a downshift, when the vacuum is high If it's rings it'll smoke on heavy acceleration. If it's rings a wet compression test will give you higher numbers. If I was doing anything, it'd get rings, seals and a valve job... at least. The thing is...

    Hot Stator Wires

    You don't measure the AC voltage in reference to ground. Measure the three stator leads to each other. AB BC AC Measure each of the stator leads for connectivity to ground (there shouldn't be any)... and a multi meter doesn't really have enough power to do this, I used to use a insulation...

    Wiseco makes a 73.5mm composite head gasket I have used Cometic copper for years without issue.

    Cu head gasket

    That valve need to be ground. You can see a ditch where it sits on the seat. You need to accurately measure the piston and bore to decide if you can re-use them. If you're holding a piston with 40 year old rings, you replace the rings, at least.

    Where to get oversize pistons for GS1000??

    if you DO go with a 1085 kit, try to find a Yosh kit. The Wiseco uses old thick rings where the Yosh uses modern 1mm rings. If you do go with Wiseco I have a free set of 73.5mm rings for you in Omemee. Who is doing the machining? They can USUALLY tell what size/over bore you need BEFORE you...
