the quick change tool was originally made by Goodwin
any real goodwin seller should have them us$80
goodwin also sells the clicker weight set for 900

the Grip N Rip Racing Products pdrive alignment tool is complex and seems to work sweet
mine only needed one shim behind the bearing. their video helps understand how to use it

IMO they are quite complex for weights
and with the big torque range of 900r
not really needed...once the adjustable weights are set
they really dont need any adjustments
the two strokes have a narrow torque rpm range
and trail conditions make a bigger difference for them

if the engineers would give us the sxs pdrive we could run a very tight belt and still have reverse
the beancounters should see the logic of only one pdrive

I adjust mine as tight as possible and still have reverse

we are still looking into why the top speed is low
the biggest change was the pdrive, thats where we are looking first

he just started on the complex ecu
engine temps also a big player in max boost and timing
fuel is another problem, is your fuel making the ecu cut some power
is 91 enough octane, is your fuel really 91
buy the highest available and hope its high enough...lol
add octane booster and see if there is any changes
I have a bunch of data from the 900t but who knows what they changed with the new ecu

even when they are running the right rpm there is no top end speed

yes torque peak at 76, but hp goes up with rpm and tourque does not fall much at max rpm

the above dyno sheet has falling boost above 7700 so it is useless for peak numbers

and now you know why the beancounters left off a boost gauge

if the tmap sensor has a issue you will get a fault code and you will be in limp mode
the ecu does a test on all sensors at startup

a motec will give some more power
but not even close to what a tuned yamacat makes

IMO the intercooler gets heat soaked and you loose some rpms

My 205 tune with the stock intercooler
warm/hot intercooler is always 2-300 down
compared to a cold intercooler
the first pass is always better rpm than the second or third

no its not....
the map sensor is in the charge tube
and the TMAP sensor is in the manifold

if your sled is down a pound or two on boost
just crank up the crack psi so it will make the advertised 17+ psi
the oem waist gates are just Chinese/Mexican cheapo's

usually if you add 1 psi crack psi
will result in 1 extra total psi
now, if the total boost is too high
and the ecu does not like it
it can easily cut some boost psi
only if the ecu can not cut enough boost
will it throw a over boost code
like a hose off the controller
cheapo actuators springs can easily be off a pound or two
