Suzuki 2 Strokes

Stock rear tire.....4.00 x 18.0 Avon RoadRider?

Thanks for the info on the jets.....I'll see what I can find at the dealer tomorrow.
As far as timing....I'm gonna have to go back into it.
I'm pretty sure the left cylinder timed first and had the fixed points.
Left points are at 3 o'clock when looking at the points plate.
They corresponded with the indicator plate seen thru the points plate.
Tomorrows another day.
I should have all the carb parts clean.

reproduction decals sells the jets very reasonable. I got the aforementioned pilots and mains from them. They're very nice to deal with. Even though I hate to wait on stuff in the middle of doing something like that, it would have been more than twice what I paid had I gone to out local suzy guys.

Got the carbs finished up today.
Picked up a set of genuine Mikuni jets as recommended at the local MC shop.
Do yourself a favor!
If you decide to replace the overflow hoses do it BEFORE you bolt the carbs to each other.
Not a fun job and I refused to take the carbs back apart!
Finally had to get a pair of snap ring pliers and stretch the hose to get it started.
The original hoses just stopped at the bottom of the bowls but I'm gonna run
them out the bottom to try and keep the engine paint halfway clean.



Even got them put on the bike.



Of course the starter cover had to go on first.......



Also got my timing concerns resolved.
It seems that the left points were intermittently shorting out against the base plate.
A little tweaking with a pair of pliers and we're in business!
I had the most consistent readings by backing the points cam into the .136 BTDC
Since that's the way the cam is driven by the crank I figured it was probably the most accurate.
At least I could duplicate readings consistently.
I'll put a timing light on it once its running.
Now if I just had my chrome back............

Just to add to Teasers jetting info. I hope you re-used the stock slide needles, and not the kit ones. That is where the worst discrepancy usually happens. All your off-idle through midrange jetting is handled by the needles, and those kit needles just don't cut it. My two bits worth. Cheers.
Fred

Yeah, that was a no-brainer....the taper on the new needles wasn't even close.
I did check the new main jets and they did measure spot on but I replaced them anyway.
Cheap insurance.
The pilot jets in the Keyster kits didn't have the crossed drilled holes.
I didn't even bother to look at them closer.
I think those are for the VM carbs and not the BS.
I tend to check, measure, document, everything as I take something apart.
This bike ran extremely well when I picked her up.
The clips were in the 4th notch down on the needles and and the air bleeds were at 2 turns out.....a little far from stock 3/4.
I left the clips at 4 and returned the bleeds to 3/4 of a turn.
I'll dial her in when I get her up and running.
Thanks for the added info.

carbs look great. did you have any of the parts (brackets, springs, etc) replated? Or just polished everything up nice. How did you get into all the nooks and crannies on the carb bodies? Bikes looking very nice.

Thanks.
Carbs came out of the Safety-Kleen can, water washed, blown dry, and then I
used a little .50 inch diameter cone wire brush in a Dremel tool to pretty them up.
I doesn't get into 100% of the crannies but it does get all the nooks!
I glass beaded the brackets and then used my little Eastwood plater to finish them.
The diaphragm covers I hit with some 2000 grit sandpaper and then the buffing wheel.
Springs were nice and greasy to start with so no deterioration there, only cleaning.

i never did know the differance between a nook and a cranie and was always afraid to ask .

Nooks are the larger of the two!
Got my new Cometics copper head gasket in Wednesday but haven't
had a chance to work on the bike until today.
One of the sons needed a radiator in his Jeep today and of course
I was allowed to work on that but not my bike! (We'll see about that!)
After a good shellacking, on goes the gasket.



A little antisieze on all the fasteners .......
And then on goes the head.



Bottom bolt too.....



Got all the cables run.







Started to put the air box in and ran into a problem........Shrinkage!



I'll have to find some new rubbers. These are still very pliable but after looking at new ones they are definitely shrunk in the middle. @#$%^!!!!
Its a good thing I'm still waiting on the chrome to get back or I might be pissed!!

I did get all the wiring buzzed out and the headlight back in this week.
After fudging all that mess in the headlight I had to dig it back out to make room
for the headlight socket! DOH!!!

what thickness head gasket did you go with?.
thanks mark

I asked the question here.
I got exactly what I asked for: .032 copper with a 71mm bore. Fits like a glove.
In past experience I've had no trouble sealing solid gaskets, copper or steel.
You definitely have to use a sealer.
Now an engine with a bit more compression is a different story.
I didn't deck the block nor mill the head.
I'm not looking for any added performance out of this bike.
I did clean up the ports but I didn't raise or widen them.
If I want to go fast on a 2t I'll get on my RGV.

Took the baffles out of the pipes yesterday.
The 30+ year old packing is definitely some nasty $h!!!^^!!!
I thought carb cleaner stayed on your hands.....I think this smell is just as persistent.
I honestly don't know how this bike was running as well as it was.
More than 50% of the baffles are all clogged up.



After overnight in the carb cleaner, a trip thru the bead blaster, 3 cans of Gumout, a couple of hours of
poking various tools etc. thru everywhere, I think I have them pretty clean!


The initial cleaning of the pipes brought them back to 'good enough to use' shape.
A few tiny chrome issues but nothing visible from 5 feet.
I'll look for a perfect set, (or build a set of stainless chambers) in the near future.




I bought this muffler packing awhile ago for a different bike and never used it.
It doesn't exactly wrap like a piece of clothe, but once you get the hang of it,
it works pretty well. A couple feet of safety wire on each and they're ready to go.



Ordered the airbox rubbers from Dillon Bros....they said they'd ship out friday.
Chrome is supposed to be back next week too!
I'm pretty much at a stand still now until something shows up.
I guess I'll have to do some work on someone else's stuff for a few days.........

Figured I'd make the new gasket for the air filter.....since I haven't found a new one.
.25 x .75 soft foam weather strip with the adhesive back work just fine.



It's definitely a whole lot easier off the bike!



Received the new offset drive sprocket from Laurie at Purple Haze Racing.
The sprocket needs to be spaced out from the case in order to clear an O-ring chain.
And I also found a use for the old rear sprocket!



I didn't even need to measure anything.
There was a very nice impression from the cushdrive hub to follow.
Saw it out and chuck it up.



Can hardly tell its there.



Chain and sprockets lined up great.
I'll have to see how close the chain guard is.........when it gets back.



Covers all buttoned up.



I've decided to get the pipes rechromed so that's where I'm headed later today.

nice work.

hard work: great
