New to me, GS1000GT

That's not much of a chamfer. You might actually need to use a ring compressor of some kind on that.

So my good friend, Jim Sawtell, sent me his NEWAY Valve Seat cutters.. Cool tools.. I also had to purchase a pilot tool for the Neway.. Now that I had all of the proper tools, I thought I would do the seat cuts during the Superbowl.. Cut all eight, from the first kick-off and finished at the overtime win. I cut them with three-angles, 30 - 45 & 60 degrees.
Placed each valve in and shined a light, then look inside the port.. Did not see any light poking through. Gonna give it another good bubble bath, then re-install the springs, then give it the, "fluid holding" test...

Valves are installed.. New Viton valve seals too. Gonna pour some rubbing alcohol into the ports to verify how good the sealing is.

The vacuum port screws are to long now... Gotta shave them down a bit..

 

[Nessism]

You may want to ask around to see if any machine shops in your area have a centerless valve grinding machine. It takes about 2 mins to clean up the face and take off a few thousands off the stem. Well worth the expense.

 

[melchiro]

I was able to verify the sealing of the fresh cut seats. Filled all the ports, intake and exhaust, with rubbing alcohol.. Let them sit for 10hrs on each side. Not a single droplet leaked out.. That NEWAY seat cutter did good.

Next up, the valve clearance check.. Did the intake and exhaust, separately, on my table..

Yeah, I'm gonna need some shims.. Only two were good.. Depending on the thickness of the required shims, if I get below 2.30mm shims, I will end up shaving a tiny bit off the ends of the valve stem.. I kinda figured this may happen.

 

[GS1150Pilot]

This is a very cool build.

 

[melchiro]

Valve lash is all done, had to get 7 new thinner shims. Now to finish up this motor.. Cam timing will happen. Got to slot the sprockets..
I ordered my new exhaust system.. MAC 4 into 1 Megaphone.. I'm going to make a new baffle.. These MAC baffles are crap.. Gonna make a 2-1/4" straight thru type..

 

[thebrandonbeezy]

My buddy had one on his skunk with no baffle lol thing was crazy loud

 

[dorkburger]

An 1100e I had years go came to me with a Mac canister system with that ridiculous baffle.
I made a straight thru type, drilled it full of holes, and added a small turnout at the end to direct the noise away from me a bit. I reduced mine to 1-1/2 or 1-1/4 at the beginning of the canister though. It had a nice sound and wasn't obnoxiously loud. It made a noticeable difference on the butt dyno.

 

[melchiro]

Yeah, won't go without a baffle.. WAY too loud, but a performance wise baffle is good for me...

So I removed the stock cylinder studs, to install APE Heavy Duty.

Also removed the charging rotor.. Used an axle and weight, slide hammer. It's the method I use on my DOHC Honda CB-F bikes.. A couple of slams and popped right off..

Does your Honda have a roller bearing crank? I'd be hesitant to put a hammering load on the crank bearings, but I'm thinking now I don't know if those bearings are cylindrical or ball bearings.

 

[melchiro]

C R A P !

I must now split the case.... Pulled the oil pan and found remnants of ball bearing cage. 8 pieces total.. Dam it!

 

[melchiro]

Found it....

Split the case and look...

The inner bearing on the drive shaft gear..

Here it is.. Must drive the spacer and bearing out..

 

[Dogma]

Well, at least you don't have to press the crank apart.

 

[melchiro]

More progress.. Lots of parts purchases.. Used transmission with good bearings.. I could not find the one bearing with the locating pin.
New oil seal for the transmission and a full engine gasket set. New shift shaft seal.

Installed the new 73.5mm pistons.

Next, the APE Heavy Duty Studs.. They are much bigger.

Cylinder block is on.. I used four big hose clamps to compress the rings and with patience, gently slid the block down.

Finally the head.

I plan on painting the motor at a later time..
Cam timing is next. Must slot the sprockets.

 

[melchiro]

Cam Timing... Fun stuff, not really.. I obtained the numbers I wanted. Slotted the sprockets with my chainsaw file..

Intake open - 34 degrees BTDC. Close - 62 degrees ABDC, which is 104 lobe center.

Exhaust open - 62 degrees BBDC. Close - 30 degrees ATDC, which is 106 lobe center.

A dab of red Loctite on the cam sprocket bolts, and I'm good..

 

[melchiro]

More stuff to show.. I stripped down the frame and sprayed it black. I also purchase a set of ALL BALLS fork conversion bearings.. I have a complete 1982 GL1100 Goldwing forks with the internals modified and the 18 x 2.5 Comstar wheel, held together with CB900F triples..

It required welding on new steering stops.

Still so much to do.......

 

[Guest]

I just love the ingenuity around here sometimes. The projects really coming along, looking great!

 

[steve murdoch]

Progressing nicely, Mel.
What did you do to upgrade the GW forks? Progressive springs?
Will this be your first bike with tall handlebars? haha.

 

[melchiro]

Thanks AZR, hopefully, I stay motivated and keep going..

Hey Steve, I did the, "CB1100F.net's," "MARU" mod to the spring and damper rod..
Basically, stiffening of the springs and the rebound dampening...

Tall handlebars?? Yes indeed, this will be my SECOND bike that I own, with tall handlebars.. My first was a 1984 VF1100F Sabre, that had the Hondaline fairing.. It was so comfortable on long rides..

Steve, I rode my, "Blue Brute" CBX , this past Sunday. Took it out on a 200 mile ride.. My back is STILL feeling the effects of riding with Superbike Bars !!! This "Getting Old" crap really sucks !!!!! All I could think about was, how nice it would be, to sit more upright and the footpegs farther forward....
