Title: The Latest in the Stable
Post by: Striker1423 on May 15, 2022, 10:55:08 AM
Picked this up on a 10 hour round trip to the Canadian border at Sault Ste Marie, MI this weekend.

It runs. But needs a battery and things tended to. The 2t pump leaks somewhere. The engine case is cracked by the chain. Needs the usuals. Chain, sprockets, fork repair, seals, etc.
Pipes and every chrome part have been painted with gray paint. Delkevic pipes would fix that.

But, aside from the need for a fresh rebuild, it is surprisingly in good shape.

That's cool.
I had a chance at one last year but it was in terrible shape and missing a lot of parts. I hope you get it good running shape quick and easy.

I loved my pink 72 J model, but ended up selling it to make way for my RZV500R.
Very smooth bikes, great for back road cruising....but keep extra plugs just in case.

Nice score and nice picture of 'the' bridge.

Nice bike, but not sure exactly what it is.  Forks look like M or A model, tank appears to be M but with L (74) decals.  Wrong seat cover but that stuff is all easy to change.  Post the engine and frame numbers and we can tell what year/model it is.

Great place to start.

Ok the frame number is
57783

And the engine number is
63014

Congrats on your new ride. Wish I had some useful info to contribute but I don't know much more other than what I've read about em. It looks really nice and it's a two stroke triple so it's pretty freaking cool in my book. :olaf:

I actually saw one  on Ebay this past winter and kept looking at it for the longest time till someone scooped it up. I recall it being painted white with chambers on her and some crosses for emblems as it was supposedly owned and ridden by a minister out of Long Island New York. He had a pretty reasonable buy it now and the most interesting ad description. Just going on and on about these bikes being massively underrated compared to the Kawi H2. He made mention of the H2's thru the roof expensive and that this bike being a bargain. A poor man's H2 in a matter of speaking and somewhat right on point. Well it all sounded good, I wouldn't know I never ridden either bike but who cares you got it and that's what counts.  :thumbs:

Alright after a rundown here's the list it needs:

Fork tubes (inner, chrome on outside shot, I COULD just super glue the pitting, but new tubes are 200 bucks on ebay from Legends)
Fork rebuild (the works)
Tires, Tubes, etc.
Carb rebuild (The works, including needles and seats)
Throttle linkages (rusted to really bad shape)
Fuel lines.
Assess and address oil pump leak.
Case needs welded near serial number.
Needs new cover near broken motor case.

I'm sure it needs a motor rebuild at some point, but that will take the other arm and leg and TIME. So, with it running now... I might just forgo that for a season and just do what it needs to get it to a rideable condition. The rest of the restoration can go over the course of years lol. I'll try to not go over 5 years on this one.

Good news is the seller reached out and agreed to ship me the box of parts his pops forgot to hand over to me (whoops lol), and that includes some gaskets, miscellaneous parts, and a complete Suzuki water pump rebuild kit.

Needing all of that, I'll guess that it needs full brake system rebuild, too.

Oh yea. That too, Rear brakes feel like they aren't and front brakes need a flush.

Oh and it also needs all new cables.

A good source for fork tubes is Frank's

Frame is late production M model 1975 and motor is also an M.

So the forks and tank are correct but wrong decals which you can change if you want it 110% original.

Oil pumps rarely leak but the feed pipe may be split.  More likely that the crank seals on #2 or 3 are shot allowing oil to be pushed out of the transmission via the breather standpipe which is beside the pump under that cover.

Cracked crankcases are common when the chain breaks and smashes into the case.

Check compression and if possible do a leakdown test to see how bad the crank seals are.  Crank rebuild is about 400 bucks including seals and shipping.  CruizinImage do great pistons for street use and they sell seals as well.

Carbs need the tiny O rings around the needle jets and are available from Suzuki.  Genuine needles and seats are a bit expensive but are available as are aftermarket. You will also need a new foam air filter element.  They disintegrate.

Teazer, who does the crank rebuilds?

I'll check the oil leaking, but when I saw it it was the same color (blue) as the 2t oil.

I ordered all the parts to rebuild the carbs. But, the throttle linkages are REALLY rusty, but I can't find a part number for them and no pieces separate from any carbs on Ebay.

Sorry I missed that one.  Bill Bune in MN is the place I sent the last half dozen cranks.  fast turnaround, good quality and reasonable prices.

I found a guy 20 minutes from me in WI and he is all 2 smokes all the time.  I will try him for my next crank and see how that goes.

Blue oil?  Is that watercraft oil by any chance?  Check simple things like a loose banjo bolt at the pump.

We've done a few cranks with Bill Bune on Teazer's recommendation. They do great work, apparently Bill is no longer involved, but it doesn't matter.

The oil pump was leaking at the old seal in the top of the pump. I fixed it using a few small o-rings on the edges and one larger one in the middle from multiple size sets I had. No longer leaks. Also replaced the six o-rings between the block and the pump itself.

Most likely watercraft oil. My Yamaha is old injector 2s from the drum at the old dealership I worked at. That's watercraft as well, but the RD loves it. Will switch over whenever this blue stuff runs out.

I just sent an X ring seal to someone to cure that same leak on his bike.  The correct seal is not available but I imported some U cup seals and X ring seals.  Both work but I prefer the slightly tighter fit of the X ring seal.

New tires, chain and sprockets in place. Up next will be the fork rebuild. I'll address the brakes when the new lines show up from Legends.

Waiting on a new grab handle stuck in isc Chicago. Oof. Til that and the brake lines I'll keep going.
