What did you do to your Yamaha today?

When I went to the manual I must have done that 5 times...

 

Went for an afternoon ride yesterday to verify that the manual fuel cock would be able to keep up with the demand. No problems even when I was in fourth at about 95 mph, you know just checking. All is good other than the rain storm rolling in this afternoon. Going to have to wait a few days before I get back out there.

 

Got the shims I needed from Chacal and got them swapped around. Not sure if it had ever been done on this bike. Went on about a 30 mile ride to test it out. Not a huge increase in power or anything but it does seem smoother especially lower rpms and pulling from a dead stop. Definitely does sound like a sewing machine now as others have mentioned. Thanks for the write up on how to do it. I bought the tool and it went pretty smoothly

 

Checked my valve clearances on my 1982 XJ650RJ Seca. All are out of spec tight. Ordered Motion Pro Tool to pull shims. Any advice on repacement shims? Shim pool active or just order new?

It went from 1 degrees Thursday to 61 degrees today. Woke the bike from it's long winter slumber and go her warmed up a bit on the road. Quickly reminded myself of how much I missed it! Spring can't come soon enough!

 

A helicoil is what I finally did, and I wish I had just done it sooner!

 

Lets just get passed the fact I am still running K&N POD filters.
I was looking at the crankcase vent tube, the one that is normally connected to the bottom of the air box.
I realized that the once white filter is now rather dark.
Any suggestions as to why I may be having so much blow by ?
I had the piston head honed
new piston rings
and the head and valves rebuilt.
Just wondering I suppose I could do a compression test to see if it is one cylinder or all.
Oh and there is snow flakes falling which for here in Medford Oregon is rare!
each day is another day closer to SPRING TIME

 

first, how long did this light to dark take? Why? it's normal, all engines have blow-by no matter how tight. what to think about is how much of that
stuff didn't find it's way to the filter and condensed inside the engine.

 

About a year I would say, I would have to think that when I had the original air box I never saw the blow by so I was concerned. Thanks for the info

 

you may be able to swap around some of your shims. so your next step is to remove shims 1 at a time to record the shim size. size will be stamped on the back or you will have to measure any unmarked shims.

there is a shim pool here or you can buy ones you need from dealership, or our supporting vendor www.xj4ever.com or new and used from ebay

Bigfitz's AIRHEAD VALVE ADJUSTMENT with Pics - parts I & II


I purchased some placeholder shims to make swapping easier

 

Well tonight we are getting an ice storm , I'm so ready for spring , came home it was 35 degrees had to touch bike as had not in a couple of weeks , cranked a few times and fired right off let it run till valve cover was hot . Sounded so good

 

Currently writing a paper for College, priorities
Looking outside and the temp-o-meter says 38 hopefully by 2 pm I will be out riding for a bit.
Did caress the fuel tank for a minute before heading off to school.

 

Polished the front caliper pucks and pins. Cleaned and decreased the rest of the calipers, seals went in and looks and feels like good. Winter project with no thread yet...81 Seca 750 (went back to the airhead).

 

Mother Nature has been very gracious and kind to central and eastern North Carolina the last few days. To show my appreciation I got the Seca 650 out and wandered about 120 miles in the sunshine and warmth through Wake, Chatham, Orange and Alamance Counties. A spectacular day! The Seca ran just as spectacularly after having it's carbs "Hogfiddled", thanks Dave.
Ciao,
John
ps, sorry, not trying to rub it in to you guys in the snow or cold.

 

Ditto... rode a few days this week here in central VA as well

 

Hey now... Though it's been annoyingly single digit here in the past few weeks here on Long Island, we've had our temp spikes too. Unfortunately, my 700 has the salt to prove that I've been able to get out there too. Even on dry pavement, she picks up the white residue. Gave her good wipe down on Tuesday!

Seems like the good weather is an "East Coast" thing. Keep your fingers crossed.

 

I started my Maxim for the first time since monoshock conversion and new wiring.

 

Had the bodywork all off and repainted original silver. Finished clearcoat today, repainting misc small black parts,cleaned,painted emblems and all brackets and hardware.I’ll let it set for a while then cut-buff and start reassembly. My profile pic is the before. Probably another week at least before fire up. Going to ONE MOTO show in Portland Oregon tomorrow.

 

Nothing .... recovering from frozen shoulder/rotator cuff surgery. Going to be a while till I can wrench on my bike again. Really bummed, need my garage time to keep my sanity. Enjoy every day you are healthy.

 

Well my keeper 82 Silver Seca is near done.All reassembly complete. Some minor detailing on the engine and I’ll be done. Started it yesterday and did some minor adjustments but looked outside at 4” of snow on the road and a winter storm watch. Hasn’t been on the road since 88.Today rain and more snow.
