Re: head bracket factory numbers

860S # 850xxx # Is the VIN number

DGM # 13xxx # is the part number

Crazy huh?

Re: Overflowing Carb

Thanks, Steve! I knew that was the case, but I have a local bearing shop here that I love an excuse to go to. I'll post up in the other section about my experience... it was far from ideal, but everything is buttoned back up now and I'll be on the road after I dig out torque specs from the manual.

Re: Overflowing Carb

The gas was freely flowing when I got it, and previous owner said he had been riding it pretty consistently... but yes, I think you are right, time to look into the tank a bit more. On a worse note, I took the wheels off this morning for new tires and found that the front and back bearings where sei...

Re: Overflowing Carb

Hey all, Thanks for all the feedback. It turns out the crazy leaking carb that I went through twice was only a quarter of the problem. It was solved by a new seat and needle that corrected the float height. The main leak was an ill-seating fuel banjo that was fixed by a closer eye and a delrin. It a...

Aluminum Intake Manifolds

I love these new parts to replace the old rubber! However, I want to carry a spare set of o-rings with me, just in case I do some roadside work on the bike end lose an o-ring. Does anyone have the specs for the o-rings that accompany these intakes? I'd rather not take them off to measure! I'm runnin...

Re: '75 860GT in San Francisco

Thank you for the parts manual images. I took this picture about a week ago to post up to show where I thought the frame was cut, and this confirms it. The paint is quite well done (or should I say it is as well done as the rest of the frame paint) in the area that was cut. I wonder how many other G...

Re: Overflowing Carb

Yep, got all the right pieces in place, the banjos just have some difficulty seating properly on that carb. I've injured my leg and can't kick the bike over at the moment, but I should have another update soon. I was able to take the bike out for a spin last weekend without too much issue, so baby s...

Re: '75 860GT in San Francisco

Ah, cheers for clearing all that up (as much as is possible with such a timeline). I know that this bike was abandoned at one point, and the previous owner did a lot of work to get it back in order. It had the GTS tank on it when he picked it up, but he made no mention of the stainless steel fenders...

Re: Overflowing Carb

Thanks for all the feedback folks. I've tried swapping the banjos and the same carb leaks every time. I made my own measurement tool to confirm the 18mm float height setting and measured according the the sideways diagram that BH/Steve shares. I used the correct fiber washer between the seat and car...

Re: 2018 All Italian Day Car & Motorcycle Show

I've usually been there on a Vespa or Lambretta, occasionally a modern Ducati. Looking forward to bringing the new bevel. Hope to me some other from the forum.

Re: '75 860GT in San Francisco

Thanks guys. Craig, I'm not sure about anything. I assumed this was a '75 that didn't sell and received the updated bodywork from the GTS line to finally sell. Frame# 85035X Engine# 85008X I omitted the last number with Xs as I'm not used to sharing vins online. My assumption was that these are quit...

Re: Overflowing Carb

There is only one way into the carb for the fuel to enter, through the banjo and into the passage going to the needle and seat. The check valves are both fed from the float bowl, after the float needle. If you have the plastic banjos on the ends of the fuel lines they may be cracked. It only takes ...

Re: Overflowing Carb

wdietz, thanks for the reply. I've swapped out the float and seat, and they are currently seating correctly and I have tested to see that the fuel overflow isn't coming from there. I've also swapped out the choke plunger, and cleaned out the choke jet. Float height is now correctly set and appeared ...

Overflowing Carb

Folks, Just fixed my fuel tap so that it now works, but my rear carb is overflowing. Doesn't happen every time. Choke plunger seems okay. Float and needle seem okay (but ill replace needle and seat anyway). I tried turning on the gas while the float bowl wasn't on and it didn't seem to be overflowin...
