Who's Buying an 175 IAME SSE?

Musgrave Racing here In So Cal is all over the SSE. Looks promising. I’m not a shifter guy and don’t plan on it.

I might have to come see that.

Yeah, it’s hard to say if SSE will grow up in the PNW, since there isn’t a series that supports it, or a contingency program/money class to motivate people to buy one.

It will see support in the PNW in the form of (what will likely be) an open shifter class. Details should be released soon by IKF.

I’m not aware of a shop in the region that supports it. Maybe Tri cities area will have something, but I can’t see it happening on the west side. PGP would be a great track to run it on, but 2 strokes are barred by King Co. govt. Mt High (Spanaway) is practically too small for it, though I guess it can be done.

IM-USA/SIMA is the de facto KZ hub in the region, & they aren’t going to be hosting it.

But Can-AM could have a class for it. So that might happen. Also the O2S Series might run it too.

What businesse(es) will be supporting it?

Any iame dealer

The 2 WA dealers don’t show anything on their respective pages ATM.

Still disappointing they didn’t include a starter option. The KZ ES really shines IMO for that feature.

Maybe theyre too busy playing w karts to update their website? Haha. I dont know. There was nothing on SRS’s website either but that wasnt an indicator of anything. Just sayin maybe a phone conversation would be better.

For me the starter is no big deal because I looked into a tilt stand that allows to tilt the kart onto its tail while running in neutral. 1 man job up and down.

:smiley:

I’m sure you’re correct. I still don’t see it happening specifically where I am, though, where KZ125 seems to be the way to go up here.

As for the starter, it’s easy enough to start on the stand. My thing is the convenience out on the track, if/when needed. For me, the extra battery weight is a nonissue (I need it just to make weight, actually).

It’s curious because the IAME 175 SS - from which the SSE was derived - has a starter, but uses a float carb. I don’t know why SKUSA didnt just go with the SS out of the box. The reason(s) for the changes are riddling from my outside perspective. I’m not sure, but suspect the rebuild intervals are very close, if not identical, between them.

The dyno numbers ive seen on the SSE (44hp 19tq) are well short of the claimed power of the european 175 (49hp 27tq). Hopefully that means the engine is longer maintenance intervals than the european 175. Wouldnt make sense to detune it if it didnt give longer life…

I don’t think it’s detuned at all.

You can’t really compare the dyno runs from two different dynos without knowing the test standard they conform to (if any) as well as the differences in fuel, carb setup etc.

You might be referring to this?

The MRC run gives a better idea as it compares different packages on the same dyno.
One thing you can conclude is that the 175 has about 15%+ power at the peak compared to the S1 supernats winning stock moto.

Compared to a KZ, it makes more peak power, but the KZ has a lot of area under the curve at the upper RPMs.

Squish is the same for the two, but the sse has a 22mm spacer on the exhaust that the euro one does not.

When you say area under the curve are you saying from 0 rpm to peak or only within the typical rev range? I thought the sse was more area when looking only at the usable range

Very exciting to see all the shifters coming out in the PNW in the last couple years. Certainly the SSE will have a place for those who want to race it.

@WheelSpin
From what I have read, Skusa has changed out the bottom end bearings, converted the barrel from a Nikosil lined one to a more standard iron liner and used a different ignition to the standard 175.
There may be other things but I cant remember what.

I’m sorry I cant provide the sources, some of them may have been in KP threads.

I am watching all this from out side, here in Australia the Super Shifter is still the standard offering with a slide Carb and Nikosil liner. Any engine raced here has to first go through homogenisation and the SSE variant has not. I am hopeful that after some time has passed in competition over there I may be able to lean on the distributor here to get this one homogenised as well, I would much rather own the SSE with its diaphragm carb than have to worry about emulsion tubes and jets.

@ Jacedownsouth

Thx for the info. Hadn’t heard/read about the detail differences. Still would like to have a starter option. I’ll most likely stick with the TaG-KZ, but I’ll check into it some more. The SKUSA specific changes are interesting. How much maintenance does the diaphragm carb require?

4 posts were split to a new topic: Road Race Gearing for IAME 175SSE

Here’s a gear calculator sheet I made for the SSE. If you recall John Denman’s one for moto, this works the same way, but with the 175 ratios (Of course)

Just make a copy to your google docs to play with it.

I’ve learned the starter option was removed because, apparently, there were issues with the starter motor brushes wearing or some such. I don’t know what starter the “Euro” SS variant has, but brushless starters are a thing these days.

Really hope IAME reconsiders & puts the starter option back in. I would’ve thrown down if they had.
