Default nsr12s3 tuned

Hi i have the chance to buy a nsr12s3 factory tuned motor. Can anyone tell me when they stoped producing this engine.The engine is new in box and a good price. What mods are done for a factory tuned engine? . Not sure whether to go this way or go for the plus 12-3, any help would be good.

Thanks Paul

novarossi tuned versions have milled crankshaft with silicone insert.....
the sleeve has some work on exhaust port
and the piston/sleeve set is specially selected.....

Sounds like its running too hot. Check your temp gun, it might be reading wrong

I need some help. I have a novarossi tsr12s3. I am having trouble with glow plugs. One plug only lasts about 4 tanks if i am lucky. I have been using novarossi #7 plugs. I am using trinity monster horse power fuel. 20% nitro 18% oil. On one of the bad plugs i noticed that the wire was like cut. Almost like someone cut it with a pair of wire cutters. I havent had any part of the coil fall into the engine though and it was only one plug that was damaged. On the other plugs there were black residue on the tips that wiped off very easily with a finger or towell.

As for head shims, i only have the aluminum one which is .3mm like stated in a previous post on this thread about running 20% nitro. Should I add another .1mm shim or is it something else?

Much probably your conrod is shot and this kills plugs, check it for wear and damage, change it at the least suspect of wear.

Adding a 0.1mm shim could be beneficial because if you're racing near the sea level with lots of humidity you need to make room for that extra humidity on the combustion chamber.

I will check the con-rod tonight for signs of wear. What would i be looking for exactly? Stretched? I am near sea level too, so if the conrod looks good i will add another shim and give it a try.
