We dyno test the kx112 stock, then bolt on a pro circuit pipe and silencer and dyno that. Then we dyno a vforce reed set. Followed by a carb bore and dyno! Check back for part 2 www.hpracedevelopment.com
Awesome video. I bought a KX100 for my girlfriend in 1999, it was so much fun to ride. Those little bikes are very fast. 28hp on that would be ridiculous with a sub 100lb kid riding it.
Any advice on squeezing a little extra power out of a '17 KX-100 for an adult ridden play bike? Or who to send the jug for (good) porting these days? I'm torn between the bolt-ons only, porting & bolt-ons, or just leaving it stock. Stroker? I'm just not sure which, if any, mods are worth the time/ money, or will be noticable with my 175 pound adult butt on it. (I don't think it's slow, but faster is better) I really like the little thing (fun/ play bike) and I would even consider doing the stroker crank w/ stock bore + porting, but the little info I can find seems to be all over the place and in disagreement. People even say "Just get a bigger bike"😂... I have bigger bikes, I want a mini! Any advice at all would be very appreciated.
Thanks for videos and time. What did you bore that carb out to diameter ? And you taper bore, so does that mean it's actually the stock diameter at the needle location ?
@@mustknowinfo2001 No they suck!!! They just adjust from whatever stock it... Problem is if stock is no good neither will the apps results. Use the pro circuit settings as a baseline.
@@HorsepowerHouse the reason I wanna see a build is to see how much you can get out of it. I ride one in my field and hits harder than the kx85 I rode once imo
@@HPRaceDevelopment i dont get what you mean with that, you dont know my background . And it was a general question...but thanks for your videos anyway
@@Motoinc he has another video where he explains that the fuel to air ratio isn't nearly as important on 2 strokes. I don't think he was being disrespectful. He's an engineer and that's how they talk.
@@HPRaceDevelopment I have a guy that will bore it measured to slide and the thickness of the bore but we’re concerned about hogging too much out I would gladly pay you to tell me much if that works for you
Omg bro that's so crazy, that bike almost hit 14k rpm on stock 😳😳 How about kx100 which has an overbore engine configuration, i think that bike can hit 14k rpm on stock 😂😂
Thank You, I am older now , my interest and love started with these smaller bikes.Firstly would love to see more of Dereks content .Hopefully to help fathers, younger ones to decide what to buy. Still young at heart watching where it all started .Derek is one of the best IMO I am from Australia I couldnt think of anyone personally better for the build the explaining run down Regards Craig
