Any issues with these engines? Thinking about going with OS. Anything to be aware of would be helpful. I ran Piccos for a few years and they were way different than Novas as far as tuning. I'm a little concerned about the c-clips. TIA..

VS_Rody

On the T1203 engines the wrist-pin clips are cut on one side so you have 50% less chance to have a problem there.
Tuning is not a lot different, as long as you do not run the engine too lean on the main-needle, you should be OK.

Great engines bear in mind the T1204 engine is coming before the end of the year probably around end of November.... I think O.S. already stopped production of the T1203. I don't know what the differences will be but O.S. don't tend to make big changes between the engine models.

To be honest we have very little choice nowadays with the demise of Novarossi our only realistic option now are O.S. based engines.

I do not have any info about a new T1204 engine, all I know that a new production of the T1203 is underway and will be shipped soon.

Thats cool. Let's see what comes out the mill. Glad you can get some T1203 stuff as we can't here and was told production of T1203 had ceased until November where it would be replaced with the T1204. Perhaps this is the last production that you might be a part of and O.S. aren't accepting new orders?
Anyway lets see - rumours are rumours after all.

Not a lot of racing has been going on due to covid and I know a lot of testing is done during the races, so not sure there will be a release of a new engine soon. Wait an see...:-)

I have been pretty fortunate here in the States. I compete in a regional series,(MidWest Series) where only one race was canceled. I was lucky enough to travel out of town to some other races that were C19 friendly with protocols. I would like to get a new engine or two soon as the winter racing in Florida will be starting up in November. Just researching my options.

I was fortunate enough to run the 2020 Miami Grand Prix recently. I broke in a 1203 combo and it was a great experience. The engine ran as good as anything I've raced in the past and held a great tune even with changing weather conditions. All sounds great, right? The quals were 4 minutes and I know there wasn't enough fuel left to run the usual 5 minutes at my home track..(Toledo O). I asked around and was told a opit will be needed to run a 5 minute qual. I'm considering adding a .01 shim and maybe a smaller restrictor. I ran it at or just below 250* F. Any advise would be appreciated.

Most engines now are designed to run 4 minute qualis as per most of the International rules nowadays. It's quite a challenge to get a standard OS engine to do 5 minutes reliably. A head shim will definitely help as will your choice of pipe/manifold. A smaller carb restrictor will make the engine hard to tune and doesn't really make a huge difference in runtime in my experience.

The Novarossi 2660 pipe with the short manifold works well on the OS and does increase its runtime over the OS pipes. I'll miss the Novarossis as those will run 5 minute qualis all day all night without much hastle.

You'll also need to drive super smooth and consistently as that also helps massively in making 5 minutes. You'll also need to run fairly lean which an OS can take and so fuel choice is also critical - I'd highly recommend Energy for this as the oil package is particularly good and you can run quite lean with this fuel over some of its competitors.

Alternatively some of the tuners out there can modify engines to help with runtime as well so worth talking to some of them to see what's out there.
