they look exactly like mine (GSX750S) coils... i measured mine a week ago... I have exactly 30k ohms on both. (on the other side 5 ohm... ) so Yours are out of specs. But I have no idea is this really bad:)

well deserved interest
Im happy to post this kind of personal builds to stay forever in search engines and get more recognition:)

I just ordered these:
https://pl.aliexpress.com/item/7x6-LED-Headlights-H4-Light-For-Suzuki-Katana-750-1000-and-the-1100/32801481585.html?spm=2114.13010608.0.0.WnqrAY
For testing. Probably will add me some points on a Cafe Racer exhibition - I don't know if I'll be using these for riding though. Will see.I wanted to order clear glass ones, but the looked really poorly made + they didn't have an E-mark.
If Katana wont look good with it - I can install it in my ZRX, what a coincidence
EDIT: nope. I cancelled. Took a closer look on the picture of Katana with this headlight in place - it's too round. It doesn't fit good enough.

Yep.. I'd say condensation as well..
Had even worse smoke clouds coming from my EFE when I first took it for a test run after a rebore and pistons.. (At first thought the loom was shorting out, so stopped by the side of the road only to find the smoke was coming from the breather hose..)
I used mineral oil to help the rings breaking in, but I suspect -somehow- this oil caried a lot of water as the engine hadn't been left sitting for that long at all during the rebuild.
After a second -long- ride and getting the engine properly up to temperature the smoking stopped..
What oil are you using?
Motul - semi synthetic I think... I need to check when in garage. I bought 3 different oils for 3 motorcycles the same time. so I don't recall which one exactly went for Katana. But it's a viscosity recommended to this engine.
What You write is reassuring. I still didn't have a chance to ride it properly and worm it up, as its still extremely lean. and on Idle it hardly worms up So I still have hope that this will fix itself once I let the engine breathe a little.

i doubt it's an alternator....
it looks like condensation
it does but:
1. condensation dissapears faster
2. it really bites the eyes, and smells like oil... 50% sure!

this thing doesn't let me sleep
It starts 30 seconds? after starting the engine...
compression is fine. the engine is working really nicely. no smoke of any kind from exhaust... WTF!
what can be burning oil inside the engine? alternator? oil pump?
-
HI,
Please share a jet config You run on those KNs (stock vs mods) -
still "smoking" and... it bites the eyes when You look close to the breather pipe... its definitely burned oil (cos what else?)... Still have some hope left, that once the engine gets to working temp - it will go away... as there is nothing wrong with the way it works...
unfortunately I didn't have a chance to ride the bike for more than 5 min yet (today I went for a ride testing new carb setup for 2km), as it's extremely lean right now on 1/2 throttle - I didn't want to fight with it...
once this is sorted - I'm going for a first - proper ride...

well i kinda followed the guidelines.
What do you reckon?
Its still to be clear coated and there are a couple of adhesive marks from the masking tape, but overall im happy and think the crystals ROCK!!!

Anyway, I rode my bike earlier today and to me there is not one bit of difference to when it had a cable operated clutch.
and are You sure that the rod in the engine cover isn't giving You any uneccesary resistance? does it work light? bearings fresh?

This is the SV switch gear and separate push pull throttle I have on the Kat.
which throttle cables did You use? any standard ones? from GSX-R? I'm planning to do the same conversion (as I have the mikuni BSR36 to try on with Katana), just considering if the length will be sufficient from GSXR.

No fuel from carb??hmmm....floats all set correctly?..float needles not sticking?..and when were the valve clearances last checked out of curiosity?
floats set. float needles checked (they are new - together with needle jets (emulsion tubes)). valve clearances i did correct before starting the engine
so no mileage since then.
17 hours ago, Gixer1460 said:'Mixture screww with broken tip' - is the tip still there blocking the hole?
ofc not. took it out, and put a new screw.
But as for today - Long story for me, but not so long for this forum
But it was definitely a carb issue.
There is significant improvement after last inspection/cleaning. I don't know what was it that I did 2 days ago, but it worked. Yesterday the bike started on choke nicely, got worm and after quick adjustment of mixture screws - it runs very nice on idle now. Revs nice, stays on RPM. Reacts to disconnecting the plugs. So it's stable now...
Still chokes on 1/2 throttle. but it's an improvement. Ill keep this post updated Next step I'll change the main jet and rise the needle a little.
As it's now running lean on acceleration - I'll also take off few discs from exhaust.
Also new Slingshot carbs just came
Yey.

Too bad. I had this conversion on the list as I also find the clutch to work very badly. I had a GSX1200 Inazuma with hydraulic clutch- it was perfect. Now I switch from ZRX1200R (also hydraulic) to GSX750S, and the difference is very big.
I did all I could after putting the GSX750S together to make the clutch work as light as possible (disasembled the shaft in the engine cover, put new bearings, made sure it's super light, oiled the clutch cable).It turned out that it makes a big difference if the handlebar is straight and turned left (when on stand). So that's a plus - during riding, it's not that bad... but in line splitting and heavy traffic, I already know that the hand will be tired quickly:)
Looking forward for new details if You figure something out. -
Hi, Second issue on the table...
My GSX750S doesnt run right.
First started - carb setup (original = carbs just cleaned and inspected. Main jet - stock. Pilot jets changed as 1 was badly damaged (but the size original) . 1 mixture screw changed as it had a broken tip. etc - carbs after "rebuild".
Running rich on idle. And doesn't rev when half throttle during cruise (IMHO also rich).
So I lowered the needle. But during some testing - turned out that 1st cylinder is not working on idle (taking the coil wire of the sparkplug - doesn't do anything). The other 3 when tested - make the engine stumble. All sparkplugs seem to be rich.
So I changed the sparkplugs (new ones). And tested again. 1st sparkplug completely clean. the rest - rich.
So I changed the wires - 1 and 4. Nothing changes - still first cylinder not right. (wires not guilty).
Tested the resistance in coils - 100% fine values (so it's not the coils).
Tested the spark when cranking - blue spark, regular (seems fine).
Checked the compression (fairly worm engine) - all cylinders nice 9,5-10.
Oil doesn't smell like fuel.
Checked if there is fuel in the bowl - all carbs have fuel (around 60-65 ml each).
Synchronized the carbs - result was fine (before sync it wasn't very bad, after was way better).
Tested for air leak (as the idle is not as stable as I would like and needs corrections) - but no leaks found.When adjusting this first mixture screw (turning out) - exhaust starts to pop, so there is some feedback.
Opened the carbs once again yesterday (switched airjets, tried to blow some more air into carb holes etc - blind shots on what can it be).
My next step will be:
1. trying some engine starter spray straight into the first carb. To see if the engine reacts to "fuel".
2. To Switch the wires again (4 with 1) to check if I missed something.
3. Changing the wires and spark plug "connector" to new (blind shot)...
4. Putting on the BSR36 Mikuni Carbs from GSXR (slingshots) to confirm that the reason is in the carbs (waiting for the courier, I bought a set from a guy who took them from his Bandit as he's switching to 40's). - biggest hopes here...
But what else can this be? Airleak on the butterfly throttle valve axle?

Nice build by the way
As to the white smoke coming out of your breather, this is most probably condensation, is it cold or damp where you are?
You don't need the filter on the pipe and I would remove the filter.
The only other thing it may be is its over heating, but as its only run for a short time I would not think so, seen white smoke coming out of the breather when been in very slow traffic on a hot day (not that much other here
)
hi. no
it's not dump here. its sitting in a dry garage, and the weather is very nice. i'm concerned a liuttle, but I'll give it some more time, since ithe engine oil only had a chance to reach 60-70 celcuis of oil temp when started for carb sync, and short test drive. so I wouldn't say it's overheating, especially it's awfully rich!

can You elaborate little more on this?

Hi,
My first post in this section
I have a question... I recently fired up a GSX750S (You can find a build thread in the projects section). Im running with pod filters so I needed to do something with oil separator vent hose as no airbox is there...
I put on like a 20 cm hose + small filter that looks like KN filters. I found after runniing the bike for couple occasions (as I'm fighting with carbs), that white smoke is coming out of this hose/filter.
I ignored it as I considered that as the engine is worming up after sitting on the shelf for 2 years - it's just burning any stuff that got there (during the valve service and any moisture from the inside)...
It's white(ish) smoke, it smells a little like oil, but not much. It behaves like 80% moisture condensate (evaporates quickly), 20% oil burned. Yesterday after running the bike during carb syncing it for about 20 min it got me little worried that it's taking too long for this to clear.
It's not coolant;)
It doesn't smell like burnt anything I know, I wonder - what can this be? when should I start to be worried?

what was changed exactly after dyno's?
Rs36 flat sided / 1127
in Oil Cooled

Can You share more info regarding the BST setup? I have a stock GSX100F engine (130bhp) and have serious issues with setting up the "cruising" fueling (top end is perfect). It's extremely rich when at a minimum throttle at low revs... Also thinking about Mikuni RS36, but would like give it one more try with the CV carbs.
Can You write more about Your tuning experience of the BST carbs
