What did you do to your Yamaha today?

I had this same issue and assumed my shaft seal was bad. After digging in I found that the neutral switch assembly was cracked and causing a weeping oil leak.

Just an fyi. Good luck!

 

Nah nothing wrong, things happen... even on this forum.

 

Thanks will keep that in mind

 

Just bought an unnecessary tool that I’ve been wanting for a while. Its a Motion Pro 8mm Mini Bleeder tool.

It’s got a check valve built in. It should make future bleeds a breeze

 

Nice

 

So what did I do to my Yamaha today... went for a nice ride and scrubbed the chicken strips off the rear tire.

 

Under the heading of "Stupid, but it works"...turning the crank during valve adjustments with that damned shallow, square, stamped steel crank trigger has always frustrated me. So I took my cheapest pair of China-grips and custom ground them to clamp at an angle so they clear the shifter and foot peg. Clamp once for the whole procedure.

This was my first valve adjustment on this motor since lapping the valves, setting lash, then putting about 150 miles on it. The 4 intake valves were all on the slightly tight end, about .10 mm. I'm guessing they probably seated in a bit after lapping and initial adjustment?

 

(Yesterday) Got a nice ride in with some of my best buds up into the lower Kettle (Whitewater up towards Waukesha, then back to Lake Geneva and home) . Light on pics, but long on scenery. Also discovered what I thought was a fuel line weeping is actually the petcock gasket. Is it that time again/already (thought I replaced 2 years ago, but looking at records, I'm still on the one from the prior rebuild - circa 2010?).

Petcock gasket against the tank or the vacuum diaphragm back cover? Last time I had mine apart I sanded the aluminum mating surfaces with 400 grit on a surface plate. Unbelievable how not flat and rough the original surfaces were.

 

Would love a report after you use it.

 

Looks to be the mating surface w/ the tank, but I haven't pulled the tank for a close look yet - dummy me filled up at the end of the last ride to make it harder on myself. Will burn some off first.

 

My SECA turned 42,000 today... at an average speed of 100 MPH up the interstate.

 

Nice, you're rackin' 'em up faster than me. We hit 40k around the same time and my last fill-up (Sinday) was at 41,3k.

 

I can't get enough of the bike! Was out again today and caught a 650 SECA Turbo in the wild going around lake Harriet in south Mpls. Don't know who it is or if your a member here but dude that's one sweet bike! Seriously looked like he just drove it off the showroom floor of W.I.W. Motorsports.

 

The wrist and clutch lever grip are healed up enough so I was able to get a short ride in just before the Saturday afternoon downpour. Felt so good.

 

Cool! You were down in my neighborhood!

 

An odd troubleshooting bit, but it might help somebody else someday...

For the past week or so, the 750 has been sputtering under load, WOT or close to it. I suspected fuel flow or plugged filter, so pulled the line, switched to prime, everything flowed fine. So I was scratching my head and on to more mysterious causes, but on a hunch hooked the hand vacuum pump up to petcock and found a slow leak in the diaphragm. Probably getting fuel at low demand and high vacuum, but closing up at low vacuum. Changed diaphragm and all is well.

 

Mounted the windshield on the 750 today. I had previously planned to use the threaded holes where the grips attach, but ended up just drilling new holes lower down. I had to bend the mounting rods to make them work at this angle.

I tried to get a line-of-sight photo, but it didn't capture my view very well. I'm normally looking over the windshield, with the top of it probably 50' down the road in front.

Nice evening for a ride, but the deer were just nuts and I had several uncomfortably close calls and was glad to get home in one piece.

 

I used to live behind the old Currans on 42nd years ago so I know the 'hood really well.

 

Took the '83 XJ650 with me on my week vacation out in Ocean City Maryland.

On last tank fill, I calculated 50mpg. However, The speedo seems read about 3mph faster at about 45-50mph so I think I"m closer to 45-47mpg
