@@PowerRepublic Great! Thanks for answering!

Thanks for the good vibes, glad your enjoying them!

glad you liked it T53!! thanks for watching!

Thanks mate

Thanks Martin, appreciate the positive vibes. Merry Christmas

noice cup of tea and some soft hose pipes. not bad

hahahaha thanks bro

Hey mate, thanks the rad testimonial. okay, L206 is coming right up. as you know we have the Tony Kart 4 stroke machine sitting patiently awaiting its new Donk. So I think the most people in the states and elsewhere are using the Briggs. I guess that is the way I have to go. Where about do you live in the USA? and what tracks do you race and with how many people? Dez

@@PowerRepublic I live in the Pacific Northwest of the US and we have a regional league with several tracks. psgka.com/links-and-references/ That link shows where we race. At my local club, Tri-Cities Kart Club, there are 15-20 in my Senior LO206 class at each club race, but regional events are packed. We also have multiple age groups using the LO206.

@@br88dy how's that concrete hairpin at the end of your main straight, surely some pile ups on that one?

@@PowerRepublic no pile-ups that I've heard of! Turn 1 is banked inward so you can take it with good speed. This is my first year, so maybe I'll see some crashes, but no one at the track has mentioned it. Although it is fairly easy to lock the rears because it's slightly downhill at the end of the straightaway. Skip to 0:34 on this video and you'll see: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xK-_DXqmodI.html

@@PowerRepublic okay just kidding, there are definitely wrecks at turn 1!

very important point, rotax comes with oil in the gear case from the factory, however I recommend changing it after your first day at the track. use 100cc of Automatic Transmission Fluid for refill. Excellent. if you have any questions or videos you would like us to do for you please comment below

where do you live?

Hey Kostas, yeah oil the filter after washing it. The Rotax ones come pre oiled

i think the sound is the clutch drum touching the ring gear

Hi Seb, awesome mate great plan for all you birthday cash. you might want save up for the Junior Max engine package as that is better for your age group

yeah reckon

Hey Erik, we don't have those engines here in Australia but I wish we did!! send us a picture via email of your kart set up with the new engine?

The top is the outlet use and the side port is the to the Power Valve. The bottom is to atmosphere. some of the older versions were different orientations, however when I run the engines on the engine dyne I can see the Power Valve Bellows moving at 7500 rpm which indicates to me that the Power Valve is operation at the correct way

Thanks for positive feedback btw. Not sure on the DD2 but it should be similar, which model EVO do you have?

Power Republic its a 125 MAX DD2 evo. Ive had a few people tell me that it is plumbed the wrong way but the factory manual has it connected to the outlet closest to the power valve vacuum outlet. However, i havnt inspected the bellows during operation to see if they are working.

Hey Geoff , thanks heaps for tuning in 🦾 I would reckon 15-20 hours for the first piston and 40 hours for a full rebuild. More if you are cruising and less if you are a pro

Hey mate, I would use synthetic oil, personally I use and recommend Motul GP2T racing oil.

@@PowerRepublic thank you mate, have a great weekend !!

Hey Vigiror, yes remove the cap, its just for shipping. that black plug is the gearbox vent. you can leave it open or what we do is attach a small piece of kart fuel line and make a loop in in down to the chassis, engine or into an overflow bottle. hope that helps

@@PowerRepublic thanks a lot my friend, cristal clear 😊, have a nice one!

@@PowerRepublic My piston is 0,02 too big from perfect. What if I worn it carefully with a way longer breaking in set, I mean 50-60 laps 7000rpm, would it be usable by then? Different piston manufacturers didn't have the same scale with sizes.

it doesnt spin

Yeah, you will need the harness and coil ecu and all electrics

Power Republic thank you

1 if racing local, 2 if traveling far, and as many as necessary to win if challenging for world titles

Sure do. Check our website

Appreciate that, thank you 👍

nah but its the same less the Power Valve stuff

no, but I always check it after its first hot run and top up if necessary.

we use Maxima Race coolant in our Tony kart radiators.

I"ll do my best

Great tip!

@@PowerRepublic Could I ask unrelated question please, about TonyKart vs Kart Republic cassis if you happened to know. On your channel there are tons of valuable content about TK and for person who want to get into Rotax/IAME X30 karting is this best kart cassis to start with? I see fairly cheap second hand chassis in UK and they look beautiful. I wonder if there is a problem with them? Are they using standard parts or I would get into trouble finding replacement parts? It would be interesting to see a video about different brands/makes and what sort of gotchas there could be if one steps out of TonyKart reign.

Hi Joe, the engine seals get put on by the officials at the race meetings here in Australia. Thanks for the good vibes

30 horses bro approx

Most guys run them up to about 20hours

@C.F TENPOINT OZ HUNTING #1 get a Rotax and go for it. IAME are excellent if everyone else at you club has one and the class is strong, otherwise if you are new just grab ya self an EVO and sent it

@C.F TENPOINT OZ HUNTING #1 😉 yeah it can be t3ech, but don't let that dull you enthusiasm

Thanks legend

yeah not a problem, 50hours is about the limit of the bottom end

Power Republic do I need to change anything in the engine before the 50 hours ?

They will go alot longer than 35 hours. I've got an engine I use for testing, must be on 80 odd hours untouched now

Hi Ibbo, We don't have one in the shop at the moment. maybe next year for you......

Leonardo Costa yeah maybe but it has an air filter

Power Republic yep man as I race in Brazil and our asphalt track is full of dirty we place our air filter on the top position that's why my concern about it.

Leonardo Costa Agreed. Up and forwards like a KZ

thanks for watching

got one you can buy ... www.powerrepublic.com.au/products/race-winning-engines-the-rotax-edition-part-one-bottom-end
