What I have tried is methylated stripper. You can get it at Walmart. I have used it on many two stroke engines that have used 24:1 oil mix. It eats right through stubborn carbon. I have used it on heads, liners and piston crowns. Put some in a container just enough to soak a piston from the crown up to the wrist pin. It cleans ring grooves and everything.You can get this stuff by the 4 liter can.
Summit and Jegs racing has a similar thing to help with ring seal you can buy from them it comes in a paste form and you rub it on the cylinders to help break the rings in on race car engines ! I have never used the stuff but I would think that it would work good on a plasma type ring where they use a real fine finish on the cylinder bore to help that type of ring seal seal up faster ! On most drag cars the rings are either seated on a dyno and a load put on the engine during that time or in the car with a couple of half throttle loads to seat them in then that's it ! Because they don't have the time to drive them 500 - 1,000 miles to break them in so they do it this way or with that ring seal stuff ! My only concern would be if you got that stuff not cleaned up real good and it got sucked into the crank bearings on that 2 stroke from the transfer ports it would chew those bearings up very quickly it looks to have a pumice base in it to do it's job and even the smallest piece of dirt sand pumice would tear things up quickly so I think I would rather pull the top end and do a hone on it just for piece of mind. Look in those online catalogs and you should be able to find that stuff if you like to use it ! Hope this helps !
Wonder if Rotax owners know about relieving the exhaust Bridge by .003 and drilling two holes in exhaust side of each piston which helps cool this critical area? See WESCO piston company for correct placement & size of holes on piston skirt.
question: Are these deposits really harmfull? I dont think so .. user better fuel and oil, and you will not get deposits... I run my 2strokes with fully synthetic oil ( none aircraft engines with very cheap carbs) and the get near zero deposits... just a little colouration

@avnavcgm No, It is just fixed jetting.
Hellosir
What is rotax engine cleaning
Why you dont just use thinner?
question: Are these deposits really harmfull? I dont think so .. user better fuel and oil, and you will not get deposits... I run my 2strokes with fully synthetic oil ( none aircraft engines with very cheap carbs) and the get near zero deposits... just a little colouration
any info on where to buy this?
Does this rotax have automatic mixture control?
Great video. What 2 stroke oil was used?
You obviously have not tried removing stubborn carbon and varnish deposit's. Thinners of many types I have tested are absolutely ineffective.
Nicee
It's the shitty florescent lighting. The camera sees it as green wen it's actually blue
any info on where to buy this?
