Why Is My Chain Loose After Every Session? - Karting Questions Answered - POWER REPUBLIC 

In response to the chain being loose after every session, just wanted to share my experience with that & that is I used to have this problem when running an OTK kart with an OTK engine mount. I fixed this issue by running a chain that was just long enough that the left rear corner of the engine mount was clear (forward) of the chassis weld on the inside chassis rail. As soon as I did this the problem was gone. Before I discovered this fix, I would tighten up the engine mount clamps to the point of nearly stripping the treads, have the stopper bolt on the chassis hard up against the engine mount & yet the chain would still be loose after 1 race. It’s because the mount was sitting on the weld & despite all chassis being welded in a jig, not every weld is identically the same so all you need is a slightly higher weld in that one spot & if your engine mount isn’t sitting flush with the rest of the chassis rails that’s when you’ll have this problem. Cheers, Apples

Good one Dezzy, Old man Na, I remember you as a young tike when I sold you guys kart stuff, and I'm still racing karts. On a run of 3 straight podiums across 2 different classes atm, and the last one was in a red OTK that I had not seen before race day. Keep the vid's coming.

I did a two year stint kart racing at club level in a rotax max about 12 years back. I found it super frustrating and kinda overwhelming with the amount of knowledge required to learn how to setup and re setup the kart and also to learn all the tricks in racing to even come within 1.5 seconds of the leaders. I wish I had found a resource like this back then! All I could find was a few books. I’m now looking at getting back into karting now and finding the wealth of knowledge in your videos awesome. It’s all making so much sense now why I could only get the kart running well a 1/4 of the time. I really had no clue what I was doing…. Instead of wasting money on tyres practising and racing to just gain and solidify bad habits maybe the better plan is to spend a little more and invest into some driver training to get the best out of those expensive tyres. Cheers really enjoying the content.

Great Vid Guys! A few things that may help some people out. First off in X30, I find EGT helps tremendously as on the Tillotson Carby's you don't have the ability to change jets, and adjusting the high and low needle just a few minutes makes a huge difference. Second O-Ring chains are much better in my opinion, I struggled a lot with chain stretch and the O-ring chain eliminated that. I know many people believe it robs HP, but from my experience, any losses are made back by the fact that the O-ring chain lasts much longer and needs less maintenance. Finally, I think that anyone who wants to start Karting regardless of age should go out and do about 3 days of testing/practice in a true race kart, not a rental. You will get a much better understanding of how things work on top of the fact you can really decide if it's something you want to pursue. Many tracks offer Rotax and X30 Kart rentals and a lot of teams at least in the States offer test days. I've seen people invest thousands just to conclude they do not want to race and are left to sell their karts at a loss. I do strongly agree with getting a good 2nd hand Kart at first so you don't have to worry too much about keeping it in pristine shape, you can find some one or two race old karts for thousands off as teams sell them after a couple race weekends!

Nice video mate. Can you do a video of a body postioning (arms,legs) in the next video? Thanks

Ah, I used to blame the chain loosening up on my engine builder... He was a top bloke and had great motors.

Thank you for your channel! Interesting content

I have a RL leopard and am looking for where to find parts and a top end rebuild kit. Where do you recommend I buy them(I'm in WA). Also should I save up for an x30 (for the tag125 restricted class). Also thanks for answering my other question 😊

Hi, I was wondering if it is normal that with an o-ring chain it seems that the the axel doesn't spin loose like with an non o-ring chain, I believe that the o-ring chain has longer longevity but does the engine loose power through this much more dragging of the final transmission? Also it looks like the chain is a lot wider and very close to the clutch drum, does this may affect the life of the clutch drum itself? thanks in advance PS Your channel is the best!!!

About the water temperature on the Rotax: Will the engine get damaged if your in a race and you cant get the temp below 70 degress celsius?

When you install a new piston in a vortex rok do you hone it a bit with a ball hone

Hello!.I'm going to buy a Rotax Max Evo. Do you recommend the Rotax Max Jetting app or is there someting better? . Thanks

⚠️⚠️⚠️ actually, the Rotax manual itself (operating instruction FR125) says 65° as the optimum coolant temp. 45° being the minimum and 85° the maximum. (In Celsius)

Also for mitigating water temp on Rotax karts would Redline Water Wetter be a viable option? I have known the product to help supercool the water quite a lot.

Hi Derek There's a thing worrying me and that is how hard I should tighten the two bolts holding the Rotax Max engine? It happened once that the engine came loose during a session, and after that I tightened one of the bolts to hard so that the bolt was spinning and a friend helped me with a reparingkit to fix it. There must be a recomended newtonmeter number for the bolts holding the engine right? It will help me a lot if you could help me with this, cause noone I've asked at the track or even at the local store seem to know. I use a pen to mark the bolt how it's tightened but it does'nt feel relaible. Sorry for my bad English :) best regards from a big fan/ Jesper

Hi there great vid as always, I just have a question on my senior max evo engine. I’m running a 120 main jet but there are some days the engine will rev all the way to 14000 and over goes really well, but then 1 week later it doesn’t. I thought it was my power valve not cleaned up etc but this week it only went to 13100 rpm. Is this just jetting?( There is no lean popping sound generally pulls well) Thanks Sam

Quick question in regards to rotax engines, is there a serial number to tell me exactly what year and model my rotax is? Have a said non evo with all the evo upgrades. Thanks in adavnce.

Hi, what Spec of Air Compressor should O be looking at buying for popping tyres and air line use whilst at home?

Hello! How do i know which chain lenght should i choose? When i change rear sprocket to smaller one did i must change my chain lenght too?

Hey Power! was wondering is DVS worth while?, I'm in Rotax JNR atm

I just got a Very Used, New to Me 2011 Kosmic, I got it mostly in pieces, I've got all of the major Components, previous Owner cut some tabs off for some reason, That being said, What is the tab at the rear of the inside Axle Cassette that faces left?? What mounts to it??

How tight should you actually run your chain?

Hi I have a question I have a Iame X30 and a mycroon 5 and my Temp isn’t showing on my display anymore just wondering if there a way to fix it?

Hi, could you tell me what the outside diameter of an Iame x30 clutch is? Thanks!

We use 60 C° for the Rotax’s
