Vintage DAP Kart Restoration Project - Episode 2: ENGINE INSPECTION - POWER REPUBLIC

[@thiswillprobhrt]

Rotax DSB Honestly the Motoplat is great. For one it sparks around 150 RPM vs 450 with the PVL, nice for push starts. See if you can nab a slide carb in the 28-30m range for ultimate waft. If they're still available and compatible, Italsistem made excellent cylinder studs and rotary disks.

[@PowerRepublic]

Hey boss, thanks heaps for the info. yeah those slide carbs are getting rare these days. was thinking about the X30 Tyrton carb as a replacement. bolts straight on

[@AlanDoveKarting]

Rotax DSB. Can tell by mount of coil and the fact the exhaust side fins are braced together. In addition it was rehomologated in 91 with wide studs to have a bigger exhaust port iirc. If you measure these you can tell which year engine you have.

[@PowerRepublic]

the exhaust studs are KA100 / X30 pitch exactly

[@AlanDoveKarting]

@@PowerRepublic the studs for the barrel and head. Measure them. I can tell you if it'd 89 or 91

Hi Mate the hl340 are the cabs used for running in ect. If you can get a hl360 they will perform better. Below are the mixture setting: Setting up your 2-cycle Tillotson Carburetor. With today's state of the art motors and stinger type exhaust systems, the following information will help you achieve the desired results that you need from these motors. Before mounting your Tillotson carburetor check the pulse track from the carb mounting surface and make sure that this track through the carb adapter , gaskets and etc is clear and in line with each other. Set the low speed needle at 1+1/2 turns out and the high speed needle at 1+1/8 turns out. Adjust the throttle stop screw on the carburetor so that it just cushions the butterfly when the throttle valve goes closed. Do not set the carburetor so that the engine will idle as this will cause the engine to lean out in the corners and anytime you are off the throttle.

[@PowerRepublic]

Thanks legend.

[@ruubjumper126]

love the video! I usually run bigger slide carbs on my dsb and dsc rotax engines, but a tillottson should be around 1.0 low and 1-1/2 on the high needle if i can remember correctly. A PVL Analog (105-458) is a good reliable replacement for the motoplat, although motoplats makes them a little easyer to start sometimes (sparks at around 450rpm i believe) and i put them at around 1.8-2.2mm before TDC.

[@PowerRepublic]

thanks for watching legend , and thanks heaps for the info about the spark. the IT was about that when I pulled it off

[@chrisguest3452]

heyy Dez .. another great vid. may be a bit eccsy but mabe try milling/cnc those welds outso you can change the rod. if you have some factory dims after getting the pin out weld up the crank and re-machine it back to new. sure mitch would love to crack the welder out

[@PowerRepublic]

yeah could machine it if desperate. but most likely just run it super rich and hope for the best !!!

[@jacob-67tune18]

Just got a DAP t70 to have rebuilt

[@PowerRepublic]

yeah boi !!! gunna sound epic on track !!

[@eugenelang1596]

Good video I also would like the information on the Z bevel box with the prob like you have. Thank you

[@PowerRepublic]

I'm pretty sure I used this and then made a metal adaptor in the lathe www.machineryhouse.com.au/M9775?MHAU_Google_16June2023_PerformanceMax_BAU&M9775&gad=1&gclid=Cj0KCQiAuqKqBhDxARIsAFZELmI5nkgGNgVf4Pz4epoBbHB-Azo7gXoYjuw1fPWulnnkzieqSEq__eoaArfUEALw_wcB

Didn't expect to see the welds on the Crank, did the job, but dodgy as fix.

Yeah reckon. Just gunna leave sleeping dogs lie

[@oscarchristensen294]

A quick question. Right now i use the size 2 in the otk seats but what size is that in Tillet?

[@PowerRepublic]

32cm approx

[@dominic4892]

Do you guys have a video on how to top end rebuild a x30?

[@PowerRepublic]

not yet, but stay tuned ......

[@pablin123]

Keep the motoplat..it is awesome. We have s very good quality copy in argentina (italsystem mvr). We usually go with 2.5 mm

[@PowerRepublic]

Thanks for the tip! I want it easy to push start that is for sure

[@59Mrgamer]

Do you have a link or a ref for the angle gage you use ?

[@eugenelang1596]

The name on the box is Zbevel box. But when I looked it up. It doesn’t have a probe.

[@PowerRepublic]

they are a f n beast of an engine. I say get one for sure !!!!!

[@BK-it6te]

@@PowerRepublic what about DD2 rotax to 175 super X30 Which one you would go for ?

[@Ian_Smith16]

1 and half turns out on high and 1 and quarter on the low that what we always started at

[@PowerRepublic]

thanks for that, can't wait to send it !!

[@Ian_Smith16]

Also a good tip, file a flat on a small washer and Araldite it into the groove on the slow running jet. You can then adjust on the fly 🪰👍 Another tip place a piece of hardwiring plastic between the carb and chain of a L bracket on the rotor cover. Will prevent and save the carb if the chain snaps, saves $$$$ 👍. Enjoy

[@PurryKitchenWithTaste]

Please make a video on how to cut off old bearing hanger brackets and how to reweld new ones.

[@AFFMotorsport]

Simplest way, but another chassis as it's worn out.

[@PurryKitchenWithTaste]

@@AFFMotorsport no i am not competing only driving for fun at my local track

[@PurryKitchenWithTaste]

@@AFFMotorsport also the frame is a 10-15year old historic crg which has no cracks and is in good condition.

[@PowerRepublic]

yeah welding is not my speciality

[@AFFMotorsport]

@@PurryKitchenWithTaste I've seen almost everything welded on karts before, never seen that done replaced. If the kart is in good condition why do they need to be replaced?

I clean my kart and engine with petrol pressurised air is it good idea or not ?

[@PowerRepublic]

Petrol is a little too volatile/flammable. It does clean and lubricant really well but.
