Jonduc, I've done the same thing with my 900 if there is little or no tearing of the gasket surface a thin smear of a non-hardening gasket sealer will likely keep leakage at bay. I'd try this first as the horizontal cylinder is pretty easy to do if it doesen't seal.

Droopy, Look in any issue of Cycle News and get the number of Northwest Sleeve. They do excellent work and are reasonably priced too. I had sleeves made for my F-1 a few years ago and the turnaround time was only a week! Real nice people too.

Jonduc, If the crank was set up correctly,30k should be no problem. I have a 75 750 GT with about 60k on it [speedo took a dump years ago] The 750 engines are way understressed and don't make enough power to hurt themselves unless you really abuse them. Check the end float with a dial indicator.Pres...

Jonduc, The idea behind preloading the crank is to eliminate any endfloat when the cases are at operating temp. The mainbearings are of the angular contact type to better absorb the flexing of the crank during operation. A slight [003" to .006" ish ] pinch should be sufficent for a normally ridden s...

Face the tangs inward toward the basket. It is to keep the plate from possibly hanging up on the edge of the basket.

Mikey, Looks like Eldert has you covered. The shipping from Holland has to be cheaper than from here in the US. If it falls through post again I'll sell you mine. Bill

Look for an 860 rear hub/brake assy I'm pretty sure they were the same on the 75 860 GT and they should be pretty easy to locate. I have one buried somewhere in my garage I'll try to find it this coming Sat. Mar 17

eG, The starter comes right off just remove the outer cover pull the chain etc. as per the manual [ you have one right? ] The battery cable and solenoid are easy too. The hardest part will be to find a non electric start primary cover. 10 or so years ago I looked into getting a spare for my racebike...

starting

Spub,I have yet to see 40mm carbs behave well on a street ridden Ducati. I had a pair on my Darmah and I never could get a consistant idle.When starting I hold the ticklers until I get a dribble out the overflow and don't bother with twisting the throttle.One or two prods usually do it.

Emptyg, You appear to have a later 860 with what looks like a Triumph or other britbike brake pedal pivoting on the passenger peg mount. Pretty crafty! The shifer side is probably a 750 shift spindle in the squarecase shiftbox. A much better shifter setup than the 860 came with. But I think you will...

lights go out

The single most common electrical problem on old or rewired bikes is poor grounding. I suggest you check that the headlight is grounded to the frame. I ran all my ground wires to a common point on the frame and used star washers between the frame and the terminal. 14ga. wire should be sufficent for ...

fittings in cam support housings

Those fitting holes were likely from a seperate oil feed to bypass running oil thru the head and picking up excess heat in racing conditions.It was a common modification back in the 70's.Usually the oil was fed from a fitting drilled into the oil galley that feeds the oil filter.If it doesen't have ...

Dave, The750 high pipes will fit but finding a set may be a problem. There weren't many around to begin with. If you do find a set they probably will be bent anyway so some adjustment (torch) will be required.A better solution would be to build a set yourself or contact Syd's Cycles and let them bui...
