hmmm... back to the past....
i still remember my STS 5P with the purple heatsink. it serves me well..in fact my 1st nitro engine. The 1st one to get me to the a-main. i would get the same engine or the updated one if not my lhs stop selling them

that time, my engine loves running at higher temp...like 130 C it perform flawlessly. Until i broke the crank pin becoz i run colder..like at 90C....my fault. i still have the original p/s though. still tight at the top..even after 4 gallons. my fault.

That's nice to hear. Looks like the D5R will replace my NSR soon Anyway, I am only worried about replacement parts since there is no authorised dealer here.

Hi everybody, I have a few questions. I just received my brand new D3R, and am getting ready for the break in process. Be aware that I am very new to nitro, and some of these questions may sound a little dumb.

1. I was unaware that there was not a plug included with the engine, and would like to know what you recommend, for break in process, and for running with 20% and 30% fuels?

2. Do you recommend disasembling the engine, and cleaning the internals before begining the break in process?

3. Should you be able to turn the engine over by hand? I can turn it to the top of the stroke, and then it feels like it is locked.

4. Should a lower nitro percentage be used during break in, or should you use 20% or 30%, as you would be racing with?

5. Should any oil, be placed in engine before turning over for the first time, or do you just put fuel in the tank and crank it?

I think thats about it for now, Thanks!
1)Yes we don't produce plug. I usual use Nova or OS plug. And the O'donnel's plug is also very good. For break-in I will use #5 plug,for race I use #6. I use #7 only when the weather is hotter than 30C.

2)Yes. I usual disassemble the engine fully. Clean it carefully. Remove the grease of the bearings. Remove all the edges of sleeve's ports. Check if there is any non smooth. Then assemble it with care also lubricate all moving parts. You will have a tuned engine and get 100% power. That is what all experts do.

3)That is normal. That is why you need to break-in it.

4)If you are not expert I suggest lower % for break-in.

5)It doesn't matter because that is a new engine. There is some oil in it already. But if you wash the engine like what I said,you need to lubricate all moving parts.

Regards,
Dino

hi Dino

I own a STS D.21 buggy engine
the initial settings of the carburator are they set for breaking-in
or must I open a bit high and low ???

my shop gave me a #3 plug , I think my #6 plug would be better for breaking-in ??? no ?

if I let the initial compressionrings in like the are, could I have troubles running only 16% fuel RB ??

I would run a 13 teeth clutch on our long circuit straight , is it better to replace it with the 14 teeth ???

will the D.21 run well with a sportwerks 053 pipe ??

i think 14t would be a safer choice and less stressful for the engine. and definately a hot plug for running in.

1)Yes the initial setting of the carb. is for break-in. You don't need to open a bit the needles. In fact in most case they need to lean the needles a bit.

2)Yes hotter plug like #3 is good for break-in. The engine will not that easy to be shutdown under rich setting. You need to change back to #5 after break-in process.

3)I still would suggest you to use 25% Nitro. Because when the nitro component is not that much,people may over leaning their engine for getting the same power. So it depend on what your friend using? If all of your friends are using 16%,well that is ok.

4)Yes,14t may better. It depend on your car. If your car is light you don't need 13t clutch bell. Also if your track is high speed track you even may need 15t clutch bell and high speed tuned pipe.

5)Should be ok.
Regards,
Dino

OT,

Don't think there is sufficient time to run in the engine for this race. Another top driver will be testing it as well ....if its really as good as the nova based engines then there should be a market for this engine as the current Novas are getting more expensive

who's driving with one?
Make sure not the chekai chekai one...if not, the result will not be as expected.
the D5R was driven by a singaporean driver, JoehWee, and won on our last year KKiiRR race and brought home RM3,000. that time, the engine was still a prototype...Sunny just let Joehwee test it.
