DD2 here on dyno with no evo internals but upgrade kit, which was Elec PV,  new ignition / ecu and new Carb.

Made 24.4kw / 32hp. Sorry i dont have a before and after to compare.

I bought the upgrade kit for my DD2, at the same time threw in a new piston.

After our first club race wasnt too happy with the performance. Im still new to karting so take my feedback with a pinch of salt.

Basically i was 2sec slower than my previously set times and felt it lacks bottom end. I am over the class weight by 10kg which is probably why it affected me so much more than others and after the festive season its probably taking me some time getting back into it resulting in my slower times.

Our track is definitely not flat either, we climb some pretty steep inclines so having a motor with good bottom end is vital which is where im losing the bulk of my time now.

If im not mistaken the squish gap has been increased slightly on these new motors which is also a contributing factor to the lack of bottom end.

The lack of bottom end has also been felt by everyone not just me, so the guys have been doing allot of testing with a combination of the older carbs and PV’s coupled to the new motors. Some of found improvements by doing this other found it to be worse by mixing and matching.

So end of the day i think its purely a matter of conducting some more testing with the new upgrades in an effort to find that ‘sweet spot’ again.

Thanks Tony,

I’ll do some investigating with Sodi. Nope, i haven’t put the kart on scales and was actually looking at purchasing some to get me started along with sniper alignment, they pretty expensive though.  I haven’t come across anyone at our local track with scales either.

The front of the kart however has been laser aligned, but ill pay closer attention to tyre wear. Inside edge seems to wear a little quicker than the outside obviously due to the slight camber. Rears wear pretty evenly.

Thanks…

Hi Guys,

Sorry to raise an old post, but came along this thread while searching for information on the RM-1.

I am currently competing in a DD2 class in South Africa driving an RM1. These karts are really cheap a 1/4 of the price of the newer age karts. So while i am slower than the rest i still have great fun participating.

However, perhaps someone on this forum knows the correct seat positioning and kart scaling % i can dial in. I’ve searched all over the web but cant seem to find any info..Basically looking to get an optimum kart setup to try close the gap a little.

 

Thanks…
