Hey guy's , I finally got to take her out on some good weather over the weekend, This was the first time I really push her hardand she felt good ! but compared to my old 93 cbr 900rr ,I was expecting a huge difference ,but then again I had kehin flat slide racing carbs with no air box and a full hindle exhaust on my old cbr. can anyone tell me about the flapper mod on the 954? I heard that is one good start. thanks

 

flapper mod is a free and easy mod to get rid of the popping in declearation.... not a huge deal.... if you want some power, get full exhuast...... air filter .. v stacks and a PCIII with a custom tune.... gain about 5-10RWHP

 

and vp fuel

 

but at least the flapper mod will help some? until I can get the full exhaust. I just need something to do this weekend because of bad weather thank's

 

you can do it..... but you wont notice anything that's not just in your head.. worth while if have time and you know waht you are doing

 

you could purchase an ignition retarder for around 50$ from dennis kirk will retard 4 pts to increase midrange and go with a vortex 520 conversion( a must if you have to replace your chain soon anyways)
good luck.

 

vortex sprockets suck A$$ big time.

 

no.. they do not suck..... they are aluminum...... so yes they wear out faster ..... that's all but they are alot lighter!

 

to dscort follow up your negative comment with something tangible such as recommending a sprocket you feel would better suit this rider along with a reason why the different sprocket would work.

 

hows about any sprocket but vortex. ive heard a lot of complaints about them. had them myself and will never buy again. unless your Racer X that can get his lap times w/in a few miliseconds or 1/4 times consistant every run you prolly wont ever tell the difference in alum and steel rear sprockets. except the fact youll be replacing them and the chain every 5-10k miles.
p.s. the front sprocket on mine was wearing out very fast as well. it too was vortex.
i put a driven steel rear on my 929 jsut recently so i have yet to see how it holds up.
