Are you skipping a valve clearance check?
I`d leave the crankshaft breather tank. It`s there for a reason. Putting a small K&N filter on the hose connection is better then removing it.

Hi Andrew,

this all makes very interesting reading ... good work.

Have a look at your commercial hose suppliers for your fuel hose as they will have it by the mile, the Pirtek's or Enzed's of this world. there is bound to be someone close by.

You could get the "pretty" stainless steel braided hose for what "Auto bling" want. I used the SS braided on several of the other bikes and has lasted well as well as looking "Gucci".

Now heading back to my other life, back to sea for a few weeks.

Not much to show today.I spent a good few hours polishing the exhaust.I t could be better but I'm not spending anymore time on it.
I gave these a whirl on the wire wheel.They'll get surface rust again but they'll have to do.
Image

You may notice I'm one nut short :wacko: :lol: .My ex friend,Mr wire wheel decided 1 nut needed a whirlwind tour of the garage floor :banghead: .After crawling around the garage floor on my hands and knees for a considerable length of time I gave up :oops: .
Image

It'll turn up one day I'm sure :lol: .So it's into the nut box for a spare.I found one that fitted right away.It's not identical but it will do for the moment.
Image

Image

I'll tackle this tomorrow.This has got to be the flimsiest exhaust clamp I've ever seen.I'll have a look around for something stronger.
Image

Not looking good Captain.I went to put the sidestand on and found the front thread to be damaged so I ran a tap through it to clean it up.
Image

It looks like the front part of the thread is damaged.I took some measurements and it appears that I still have 10mm to 15 mm of unused thread after the bolt is all the way in so on Monday I'll get a longer bolt to take advantage of the remaining thread.The bolt still bites so with the extra thread and some Loctite all should be good :thumbup: .

Cheers
Andrew

Staintune do some really nice clamps, but were/are $40 a pop + postage, broke both of my originals 1st time I had them off and put them back on and tried to tighten 'em up. :banghead:

I got a bit done today.It's time to put the exhaust on.First to work out what bit to put on first.
Image

That'll do for now.
Image

Image

I thought I'd quickly throw a pipe on just for a look.
Image

It still needs a polish.
Image

I also tightened everything up....except....you guessed it,the headlight/oil cooler.Off it comes again :banghead:
Image


.When I connected the power up the instrument lights came on.When I turned the ignition on they went out and the headlight came :lol: .A change of plugs and all worked as it should.Dash lights and all :thumbup:
Image

I got a few little things finished like this....
Image

....and this.
Image

It's actually matt black :huh:
Image

And she stands on her own after a long time in pieces :choo:
Image

After giving the pipes a good clean this is how she now looks.
Image

Image

All that's left to do is put the valve covers back on,fit the tank and fire her up.I could have done this today but want to savour the excitement....or dissapointment if it does'nt start :,( .

Cheers

Just remembered that I have to pull the throttle apart as it's notchy and sticking when I twist it.Oh well.

Early report today.I had to find out why the throttle was sticking so it had to come apart.
Image

It all looked good inside so I reasembled it and....still sticking.Pull it apart again,but this time clean some of the old grease off and reasemble it a bit more carefully and presto,works great.
Image

Adjust the free play.
Image

Then attach the choke cable.What a pain in the arse.It takes a 7mm spanner which I don't have so a bit of improvisation and all good.
Image

Some oil in the top end.
Image

And button her up.
Image

I found out the small bolts I found earlier actually go on the front lower valve cover.

On with the tank.
Image

Connect up some power.That's a good sign.
Image

A squirt of Start Ya Bastard.
Image

And....it lives
Image

She's having a wee smoke after her impressive performance :lol: .
Image

I only ran her for a couple of minutes as I had a fuel leak from the old,hard fuel lines.Now I can get on with the rest of the finishing off things like riveting the compliance plates back on etc.

Cheers
Andrew

edit:new plugs too.

Bad weather???.It's great down here....just don't move here ok :lol: :lol: .Yeah,that's a funny movie.One of my favourites.
Peter,do you remenber if you had a rubber support between your tank and the frame on both the top tubes on either side of the tank?.I did'nt get any with mine but am wondering if the rubber tank supports at the rear of the tank are used instead.
You can see the 2 rubber supports on the cross brace where the top shock mount is.
Image

I seem to remember Phil? saying he did'nt have these 2 small ones that are on mine.

Hey Andrew,

Meant to be 2 of these rubber blocks there towards the front, and the tank just lightly rests on them, think you can get away with out them if need's be but always looks like somethings missing to someone who knows the bikes.

edit: just realized mine never had the rear ones looking at that picture, always wondered what those mounting holes were for, to quote Jackie McDonald "Folks are dumb where I come from" :lol:

Cheers

Peter

Thanks Jackie :lol: :lol: .I think they may have introduced them because of the rear tank support cracking.
