Got the Pepto Bismol handy?....
Your photos show a 3-port kit, does your photo posted April 19th show that your Bajaj casings are 2-port? It's a 150cc isn't it; is the Pinasco 3-port kit OK with your casings? I take it the kit is 177cc? You still haven't given any info on kit; need numbers and stuff to read, more than photos, particularly now about this question.
Whilst you find an answer to that, I'll carry on as if it wasn't the elephant in the room; so, info outstanding from my previous post:
1) Have you got a link to crank? Have you checked your previously stated 10° and 112°? Confirm also for port timing calcs: 60mm stroke, 105mm conrod?
2) Have you got a link to cylinder (spec)? Can you measure squish? Do you have head gaskets with kit too?
The measurements for your Transfer and Exhaust with -0.075mm deck, can be input into these calculators:

http://www.race-base.com/2t-tools/steuerzeit/index.php
I get:
Td = 125.15°
Ed = 175.69°
BD = 25.27°
(Id = 101°/48°)
(Transfers high, Blowdown minimal, Inlet too short).
Transfer duration of 125° gives you peak power at 8500rpm, which I doubt is your aim, but gives rise to more info outstanding from my previous post:
3) what type of riding you do, what you're used to riding (did you ride this one before?), what you want from engine, and whether your shiny new bits are going to help or hinder the job.
At present it seems to me to be a bit of a mess with Transfers too high (are they for you?), and piston already 0.75mm above Deck (need squish to assess this); this gives rise to next:
4) Are your Transfer and Exhaust dimensions taken from the same point as your “0.75 mm the piston is above the cylinder deck”; there is a head recess in your photos – You need to be sure you've measured from same point as deck.
I expect you've noticed that your large transfers in the cylinder are much bigger than those in your casings, and I've a nasty feeling those are 2-port casings too; this leads to next question:
5) Are you prepared to be cutting your inlet and transfers in your casings to improve inlet timing and open airflow into cylinder? Have you done much of that before? I'm not sure even how well it would work, if at all, on 2-port casings.
6) It may also be (if a decent combination of base gasket/head gasket/squish/crank can be achieved) that your Exhaust port needs raising in the cylinder; is that something you're prepared for? Have done before?
7) What are the gear ratios (or tooth count on Primary, loose gears, clutch and wheel/tyre size) that you have there now with this engine?
My first impressions are that you've bought a flash kit and crank, but it's an old 150cc Bajaj (2-port?) engine that will take a lot of work to get the most out of those parts, when it seems you're not really sure if that's even what you want from it. The few times I've done mild tunes on 150cc engines I've ended up avoiding long cranks, an I'm also not sure Mazuchelli crank timings (when checked and confirmed) will help either. I've ended up sticking with 57mm and cutting a standard crank for Inlet timing.
Whatever your replies to the above questions, and whichever way you decide you want to proceed, you need input from people more experienced than me (with this kit, with LS cranks in 150 engines, with 2-port casings!?!?, with any Bajaj peculiarities.....). I don't want to be the one to get you cutting up your expensive new kit! - Or to be telling you it's the wrong kit.
Have a read here, and see if you can get some of those chaps involved in your build; they seem to have met similar timing issues and (possibly by now) made progress past them. First point to establish is if this kit and crank are going to work, in your (2-port?) engine.
Here is a Pinasco 177cc 2-port kit for information; I don't know if it is necessary, or compatible, or if 3-port kit is OK to use (note the 3rd boost channel in the cylinder because there isn't a 3rd port in the casings):

This write-up suggests, at least, some care is needed with 3-port kits on 2-port engines (whether it's a waste of money for what you might achieve with it, or even achievable, is another matter):

More background; see here at 14 Mar 2018, Rob Hodge mentioning 2/3-port Bajaj engine/kit problems, AND the flywheel taper on the crank - I'm more convinced I'm in (for me) uncharted territory, and you need someone with Bajaj and/or 2-port engine experience:
Bajaj 150 motor question
Tpye 'Bajaj' into the search on this forum, and there's loads of threads where you might find some answers. I hope I'm wrong, but my quick passing on of a bit of basic port timing theory has got a bit trickier as the details emerge.
