RE: STS Engines
the d28m #2805 with standard backplate does look like the d28 pro 5 port #2809 after doing some research, but it has a three port sleeve. mine is a 5 port sleeve it just has black crankshaft.

Dude you got ripped on the sale. The engine you bought is the D28M 3 port monster truck engine with a standard backplate. All the older versions of the 28 and 30 came with black crank shafts. Do not go by that #, because it is false adverstisement. I went to rcmall and compared it to nitrocountry rc and sts website. They now sell the older versions with a standard backplate. It looks like the newer 5-port, but it is not. My 5-port came with silver crankshaft. Go to nitrocountryrc and look at the older version of the 28. It has a black crank shaft. The newer version is just called the D28, not D28M. The M stands for monster truck. Also, that was the reason your engine was so cheap ($118). All the 5-ports 28 are much higher than the price you qouted. It sucks, but that is what happened. Go to this website and click on the 28 section and look at the standard engine and compare it to the Team engines. You will see the crank shafts. http://www.stsrc.com.tw/index.php

so did i get ripped off or not mysts 28 is a 5 port but has the black crank. it runs way better than my xtm 24.7 . revs more and has more power.

RE: STS Engines
No, I was going to mention that you don't have to repeat yourself quite so much, but I've had enough of my posts removed by the staff here so I erased it and put the dots in there to take up space. 
I'm glad you're happy with the engine, and you've given me a good place to get mine if/when I decide to replace the D28M with another STS product. So thank you!
BTW - it would be for my own Mammoth ST.

RE: STS Engines
Updates on the S21T engine:
I have roughly five gallons on this engine and it has performed flawlessly. It still has great compression and appears to have a lot more life left. I am running it in my MBX5T with the Dynamite 007 ht pipe. I timed the fuel usage under track conditions last week and was getting near 12.5 minutes per tank. That is no lie. The engine has great power and speed. I am definetly going to stick with STS as my race engine.
*****The only problem that may occur is that your low end needle may need to have plumbers tape to keep it from backing in or out.*****

RE: STS Engines
can someone tell me what settings they use on a mkII? the bottom end sucks badly and no matter what settings i use it struggles to get up and go. i had the sts pipe on it, the .21 pipe, i tried the dynamite ht pipe, a rtr pipe that came on a kysho buggy and a pipe that came with my hotbodies truggy. I think the kysho pipe worked the best and that wasn't that great. And yes i put plumbers tape on the needles too. any help would be greatly appereated.

I have the MKII and it runs great. As far as settings like any engine you tune where it runs properly and there is not any set setting for any engine as there are to many variables! Yes it could be tunning, clutch or many other things. [X(]

RE: STS Engines
o.k. 46u it sounds like you have run one of these motors before. did you run the sts pipe with it? did you have it on a truggy? i had mine on a truggy and the bottom really struggled. now i take off all the clutch parts and put them on a v spec, thats an OS motors for all the dumb asses in here, and not a problem. same pipe as well. my main question is basicly if anyone else has had problems with these motors, plain and simple. why is it so hard for people to just answer the question on these forums?????????????

For your information besides my 4 STS engines I all so have a V Spec among many other engines. But with your altitude I will decline from helping. You are the one starting the BS and I will no longer take part in it.
