1982 Yamaha XV920R Project Bike

[Hellgate]

Hey Everyone! I picked a new/old project bike this week, a 1982 Yamaha XV920RJ (Seca). For you Euros, Aussies, and Kiwis, a TR1.

I first saw one in '82 or '83 when I was 17 years old. It represented everything US motorcycles were not. It was a true Euro sport/turing bike.

In '82 Chris Steward won the AMA Production Battle of the Twins National Championships on one. The bike he rode was bone stock. So much so, when he crashed, the cornerworked handed the OEM tool kit back to him!

I'm not exactly sure what I'm going to do to it. 1) Sort, clean and service. 2) Lose weight, it's about 490 lbs.

This is also the very first Yamaha street bike with a mono-shock rear end. Mine is number 188! :thumbup:

That is sweet!
I wouldn't change anything but the oil
There is just something about the older bikes...I would get a mid to late 80's FZR, if I had the extra doe.

Bet it can pull and you know it'll sound sweet! Also a great looking bike from it's time.

cafe racer or a nice street fighter.

I had a Honda CB400 a year ago. It was my first bike.

My brother and I did a complete restoration of it. We took it apart to the last bolt.

I decided to sell it.

From the money I sold it for, I got myself a 2005 Suzuki C50T.
I still regret selling the Boulevard. It was an awesome cruiser.

Neat! Is that the same bike as the Virago?

Yes the same bike, but with different styling and forks. Other than that it is the same thing.

Thought it looked familiar, I almost bought one many moons ago when they came out..

 

[Hellgate]

Well the bike arrived safe and sound today. In a word, mush; suspension, brakes, saddle and floppy handling! After riding a 30 year old bike you really appreciate new bikes.

I've got a bunch of parts on order; tires, fork springs, brake lines/pads, levers, blah, blah, blah...

 

[DefyInertia]

Nice!!!

Post a sound clip if you have a chance.

FJ600 Wheels and brakes; bigger rubber, drops front end ~1 inch
530 Chain, remove 630 enclosed chain
Avon Tires

Save a ton off the rearend with the YZ swing. It's alu, whereas the OEM swing has cast steel/iron parts.

She's a porky gal!

Here's a few new photos from this weekend.

Rearend is back together, forks rebuilt, All Balls steering bearings in, new cables, tuned up, more cleaning, the cleaning never ends.

Learned that an FJ600 front wheel is a direct bolt on. Only the wheel has a flat spot and the rotor bolts contact the XV920 calipers...if it's not one thing, it's another.

Lots of progress over the last month. A few starts and stops too.

Okay here's an update.

Phase 1 - Completed

R&R'd
1) Fork seals
2) Progressive Suspension Fork Springs, Bel Ray 15wt oil
3) Avon Tires
4) SS Brake Lines
5) Tapered Roller Bearings
6) Tune up; plugs, filter, valve adjustment
7) Oil and Filter
8) New Brake shoes
9) FZ6 foot pegs, much cleaner looking, better feel of the bike
10) MAC 2:1 Exhaust
11) Motion Pro Cables - All
12) Re-grease all pivot points; swing arm, shock bushing, wheel bearing, etc.
13) Clubman Bars, Renthal gray grips, Bar-end mirrors
14) FZ1 MC
13) Removed 800 lbs of sludge/grunge

Phase 2 - Completed

1) Race Tech .85 springs, Progressive Suspension OUT!
2) Race Tech emulators
3) Fork Brace
4) Moved forks up another 10mm, 20mm total
5) Preload set at 20mm
6) Static sag is about 25mm
7) EBC rotors, pads, and new Yamaha rotor bolts installed. Perfect! Rotors save another .45 lbs off the front wheel!
8) Renthal Road, Ultra Low Bars, very nice. The clubmans are fun but too low
9) FJ600 Front wheel, saves about 4lbs, and is an 18" wheel, about 1/2"shorter than the OEM wheel. The floppy chopper steering is gone. Bare I say, it's almost flickable.

Phase 3

1) Fit FJ600 Rear Wheel
2) FZ6 rear disc brake
3) Convert 630 enclosed chain system to exposed 530 chain system
4) Rebuild and tune carbs
5) Steering Damper

Well not huge gains this week but important small ones.

1) Solved the oil leak from the oil filter area. There are actually FOUR O-Rings that are required. I hold only three in. The one that was missing is a small one, the diameter of a 5mm allen screw, that goes between the case cover and the oil filter cover. $14 in parts, $12 in shipping later the problem is solved.

2) Received the needed FJ600 wheel spacers. As I guessed the XV axle is too large of a diameter for the FJ wheel. $14 in parts, and $12 in shipping later an FJ rear axle is on the way. And this will be a part I don't use as I need to have a machine shop make an axle for me. However I'll use the spacer that comes with the axle. A spacer that Yamaha no longer makes.

I found a motorcycle machine shop. They build dirt track racers, and claim to be a "full service machine shop." If this is the case they should be able to whip up the parts I need easily and quickly. As I'm finding out in OKC quality "stuff" can be very hard to come by. Austin, I know of a dozen speed and custom auto shops. Here nothing comes up on the Google. Nothing, and people on forums say to go to Dallas.

Here's the view from the beginning of the rear wheel removal...

I installed the Singapore steering damper, and the new Shoari battery. The battery saves about 9.5 lbs.
