What did you do to your Yamaha today?

I rode my seca 750 150 miles into the mountains of northern washington state on 2 lane twisty roads, and the old girl did real good !

 

Rode from Kamloops BC to Prince George BC, on approximately 54mpg. Quite satisfied by that

 

Checked valve clearances, fixed valve cover leak, replaced bent RH footpeg. Good day

 

New tires (Dunlop D404), valve shims, vacuum adjusted the carbs, and rode 500 miles through the mountains camping and having fun with like minded friends.

Now that 99% of the mechanical work is done, I can start on the cosmetics.......30 years of neglect by POs.

 

50 mile Oregon backroad ride and trying to wrap my mind around a carb job ...... has to be done but don't want to do it.

 

Not today but recently added a backup camera. See different post subject adding rear camera.

 

Today, I went outside to repair my tach. During disassembly I broke a bolt off in my headlight support bracket, where the right side of the gauge cluster bolts. After repairing the tach, I attempted to extract the broken bolt. Much to my dismay, I broke my ez-out into the drilled out bolt. Looks like I've got to wait for more downtime to take it to a machinist to properly extract the broken bolt. Until that time, I just have the bracket secured with zip ties. Unfortunately, this is my only source of transportation at the moment.

If I can't get that blasted bolt out of the bracket, I may just wind up purchasing another for the bike.

 

It wasn't today, it was yesterday, but I fixed the highbeam light, a fault in the battery sensor wiring, lubricated my cables with an ingenious method: fitted a vacuum hose over the cable end, poured oil down it, then fitted the air compressor blow off tool to the other end of the vacuum hose and pressurized the line until oil dripped from the other end.

 

installed all new shims, alined the cams, put in a new valve cover gasket, new YICS port gasket, put the exhaust back on also with new crush gaskets, put the carbs back on, installed new gaskets for the carb intake boots, hooked up the spark plug wires, and basically reconnected just about everything that goes along with having the head and carbs off the bike! tomorrow i put the tank back on and rehook up the battery and see if i can get it started!!

 

I took the Seca for a ride today and then took this picture of it. Oh, also did a little more paint stripping on the Maxim's tank.

Let's see... over the past week or so I've: worked on rebuilding and painting the front brake calipers, diassembled and cleaned ignition switch, fabbed saddlebag supports, relocated my rear turn signals so the bags work, and swapped my front signals from $15 ebay specials to stock. just need to finish cleaning the caliper piston seals, put them back together, bleed + then ride!

 

i painted the frame... baby blue. looks better in person. (the picture is of the second coat, i did three, with no clear.)

Changed the final drive oil, did an engine oil and filter change, removed headers to replace header exhaust gasket as #1 had a leak...broke one stud...realized the gaskets I have are the wrong ones..removed broken stud, ordered more stuff of xj4ever, replaced choke cable....was getting ready to vacuum sync, but that is on hold until the exhaust is put back on...otherwise, just another ho-hum day in paradise.... time for a beer....

 

New discs [Brembo],stripped and painted calipers,fitted new seals and dust seals,new pads, stainless steel brake lines,bleed brakes.Brake Nirvana awaits. 8)

 

Put the GPS on my 650 Midnight and checked for speedo error (MPH). Since most Japanese bikes I have owned have fast (gracious) speedo readings, expected the Maxim to be the same 3% or so gracious.

At 45 GPS my speedo read 46. Expected speedo to read fast.
At 60 GPS my speedo read exactly 60. Interesting.
At 80 GPS my speedo read 78. Didn't expect this. Expected the speedo to read faster than the GPS if anything.

So, for my purposes, my speedo accuracy is ok with me.

 

Popped the front brake caliper dual pistons out with compressed air, worked like a charm!

I watched carefully while doing it, and I held the piston that moved first with adjustable pliers (called Robo-grip) just enough to prevent it to pop out before the other piston was ready to move out.

Then started to clean the mess in there!

 

Better slow down midnight

 

Got the bike inspected, changed the drum brakes, polished drum housing and rear wheel, sanded alternator cover and buffed a mirror finish on it.

 

Over the last four days I've taken the engine out and split the case in half (top/bottom) in order to inspect the output drive gears in the transmission. Dag-gum, wound't you know shift fork #3 was all burnt up and scarred.

Today I actually removed the clutch and drum, oil pump, oil filter adapter, lower engine bolts, crankshaft ignition timing mechanism thingy, output shaft, lower half of the engine case, shift fork shaft and forks and output transmission gears and shaft.

Can't wait till I can say that I put it all back together.

Thanks for the concern.

But I was on the interstate for the mile or so of the 80 mph test. Don't generally ride the Maxim above 70-75, and then, only on the interstate at those speeds every now and then.

My VMax has been my go fast bike for the last 14 years. But at 55 years old now, even taking that one in the upper numbers rarely occurs anymore. It is still a good travelling bike (with the Corbin saddle of course).
