Hey guys.....here real soon I'm going to tear this thing down for a fresh top end , and while I have her torn down , I am planning on doing some motor mods.
The goal is to get it running about as strong as I can , while running strait VP C12. I don't want to use the Oxygenated fuel ( as it costs a fortune ). So I'm looking at porting at so forth.
I'm looking to get it to run stronger on the mid-top end ( that's where we mostly run these 125's at anyways right? ). I'm curious as to what you guys know about the different head and base gasket thicknesses that Husky / Ktm sell?
Also....I plan on sticking with the FMF power core ( non shorty ) because all the tracks are bigger outdoor stuff....no tight stuff. The Scalvini pipe I have on her now , I love the looks , but I'm going for performance here , so if I need to change that out , I'll keep that in mind.
I'm wondering if any of you have modified any of these newer Husky / Ktm 125 motors , and what your thoughts were on how to go about it? Chuck Davies?.....anyone else? I know Chuck went full bore with a crank and all that stuff.....would like your input too please.

They give no definition of what this is , or at least what I can find.
I also had the tranny out so I had Yoshimura ISF process it.

What’s your email, I’ll send you the service manual. I brought it Kinkos and had them printed out all nice.
I got the tranny all back together by using the manual.

And what do you know about the different base gasket thicknesses? There is a big range. Would you happen to know what thickness is in there stock?
Not the right way to do it, but I measured with a caliper the gaskets that were on the bike and just got a close as I could. If you buy a gasket kit, it's got a ton of options and plenty left over for next time.
That STIC carb mod looks pretty insane, almost +3 HP.
I just measured the buds silencer, it's 24mm.
FMF shorty has a 22mm outlet also, i would look for a larger diameter endcap from the full length powercore
Also....was this run I run on a stock motor?
Edit.....nevermind the question above. Saw your reply to macz.
Pit Row
These runs were 2018 150, fatty pipe and vforce. I know you've had problems with the vforce, the dyno operator found the vforce added no power, but improved ease of jetting and reliability
Dealer 1 (where I normally buy fuel, but out of stock right now)
u4.4 $79.95
C12 $79.95
Dealer 2 (only option to be able to ride this weekend)
u4.4 $94.98
T2 $74.98
C12 $76.98
Jeff, check this out! Its 295 but seems to do a better job of getting air/fuel in the motor so it really improves mid and top performance significantly. There are a couple good threads on thumper talk regarding the product with testing and dyno runs and seat of the pants reviews... it seems to work well!
On this STIC mod......after doing a little research , is this Harris performance , is this Derek Harris that posts here quite often? And damn.......I'll be into a new PWK and metering rod for over $600.00 , but from the sounds of it , it's money well spent. Maybe I'll skip all the porting , and focus on a new top end , along with a modified pwk / stic modded carb.
T2 fuel, one pilot leaner, leanest on the clip and 1 or 2 richer on the pilot. It does need choke sometimes which tells me the pilot is good.
I have never ridden a bike that runs so clean and crisp. My kid is one lucky dude, he had good grades, so I've not managed to confiscate the bike yet lol
I have a good friend who's son is on KTM 85s and lynks did the motor, with a full FMF system, I have never heard a better sounding two stroke, ever.
Post a reply to: I need / want to mod my 17' Husky 125. Some advice?
