Unveiling the Key of Reliable and High-Performance Two Stroke Porting by Pro Circuit

Looking to maximize the power and reliability of your two stroke dirt bike? Think porting work is not for you? Think again as in this video I sent my 1999 KX250 Cylinder and head to Pro Circuit for porting and head work.
Jake from Pro Circuit tells us what they did and where you can expect performance gains from their in house cylinder porting and cylinder head cutting.

I have yz125 2003 an apex head an lectron carb now its dangerous fast

[@justinmoock7506]

I have a motor I sent to pro circuit years back(2006 kawi KDX200)and had them do mod001(porting&head mods). I will say that this engine couldn't be more perfect. When I took the headlight and tail light off and put the "KX kit" plastics on it,every person that has ridden it thinks it's a kx-250! This engine is absolutely sick. It has an angry powerband that is super responsive. On the down side I have to run very expensive leaded race gas at a minimum of 112 octane,but other than that,I can VERY HIGHLY recommend pro circuit to do it motor work

[@Thepianobird]

I wish you guys mentioned why you dont do any polishing.

[@zodzod9378]

Good power old is the new NEW love it ! Little john from the UK

[@chrisr.1391]

Let’s go!!!!

[@GregHitchko]

One of the things I'm most excited about!

[@builtfordtough4499]

They changed next to nothing. All they did was smooth the casting.

[@GregHitchko]

I should have sent it to you then haha!

[@builtfordtough4499]

@@GregHitchko Yeah I got one here that Mitch ported back in the day. Cut base, raised transfers and exhaust. Enlarged booster transfers to max. Larger exhaust sub-ports and the hooks in the transfers you would have to see to believe.

[@mid-ohioguardian6927]

The guy in the vans shirt didn`t know anything !!!!!!!!!

[@user-nh5sq8dy7n]

Hahahaha look at @builtfordtough4499 talking like he’s better then pro circuit then u click on his pic of duct taped numbers and 2 feet of air with the style of a drunk Jeff Stanton in the late 80s lol…… I think pro circuit did a little more then smoothed out the cast lol

[@MegaStreet11]

Hey man what did that cost?

[@ryand8639]

[@Patricks_Projects]
