    09 RMZ 450 Mid Throttle Blubbering?

    Hi just wondering if anyone might know what could be causing the med throttle blubbering condition ,bike is stock except for a fmf 4.1 slip on using just pump premium.seems worse when its hot outside,i was wondering if maybe the packing in the exhaust getting worn could cause this.but not sure,going to try the stock pipe and see what happens,

    FMF! > Pro circuit

    We did some testing Yesterday with a fmf fatty not the factory with a PC silencer not the shorty and it did seem to perform a little better than stock set up a little louder but crisper and more barky sounding could not feel much torque difference but had a little boost on top.originally the PC did not sound so good until my friend repacked it made a big difference.The fatty did not seem as good as the stock pipe when using the stock silencer. when combining the Fatty with the repacked PC the Performance and sound seemed def better, others seemed to agree also.when I asked the rider who is a Pro that has Qualified for nationals before what do you think he said he cant really tell much difference but did feel the fatty might pull a little better on top, that is the combo we will prob try at hi point,we may try the Ti FMF silencer later as well.

    Race Gas

    I had the same thing happen on my 08 yz250. I have 2 08's one has alot of time with a new top end and the other one new just broken in I mixed c12 50/50 in the new bike and compared to the older bike and it felt less responsive and a little slower than the older bike with pump only. I was like whats going on so I called my friend who knows what on gas and he said the c12 will make it smoother and run a little richer which is exactly what I felt, no more c12 for us, U4 is probably the way to go.

    Wiseco single ring piston and titanium coated ring

    I cant see the single ring making any more power for more than one ride with a pro rider or three rides for anyone else they dont hold up as well as the 2 ring setup.we had a KX 250 with the single ring, it seemed like after 1 ride it was already a little weaker.

    YZ250 For The Nationals?

    Hey guys I was wondering what your thoughts were about trying an 08 yz 250 for the Nationals, we are thinking about trying it.The Rider weight is about 160lbs with gear on.The stock motor seems hard to improve on so it will probably be left alone.Suspension and a bigger front brake are a couple things we will do.We know starts will be the hardest part but hoping we can get lap times close to get in the show.

    I also want to know what bend they are I have an 08 and tried the carmichael twin walls and they felt to high so I put the pro tapers back on. Anybody know what bend stock tapers are?

    tire size?

    That size is too much tire for that bike saps horsepower plus the rim is not rite for it and flats come easier run 13lbs air in it check every ride.

    Sticky\heavy throttle.....out of ideas

    I had same kind of problem you need to replace the cables and make sure the throttle is not pushed on the bar too far, the honda cables get sticky where you cant reach with wd40 also wd40 helps but is only short term you have to use it after each wash.

    best pipe ?

    Most riders dont have any problems with KX valves because they dont ride as hard as the A or pro riders, they also improved the valve seat material according to KAWI. So more than likely no probs, for you. what up G.
