Your gonna need:
3 geniune Mikuni carb rebuild kits. 129.00
2 caps for the carb rail to block off 2 inlets
20-21 ft of fuel line.
clamps for all connections..can be tie wraps,oiteker clamps or stainless steel clamps.
triple outlet fuel pump
2 gas filters--watch the orientation with the arrows on them
1 oil filter
peferably a 12 inch pulse line or shorter with a braided line that wont collapse
keep your restrictor from the old return line.
get a stubby 12 mm wrench for the carbs.
dont snap off the oil pump rod nylon connector holding it on. it snaps on and off.
remember the orientation of the oil rod.it looks like it can go on 4 ways. it only works 1 way. the other 3 ways it wont fit right.
just take the carbs off, not the manifold!
take off the blue caps on the high speed adjusters- adjust with them off. they only allow a 1/4 turn adjustment. i just threw mine away..lol
check the needles and seats for wear.
write down what jets you have- they are under the jet block.big is main, small is pilot jet.
mount the pump higher than the pulse line fitting.
The diaphrams go on only 1 direction. when you take off the covers, look to see how they go on. if you put them on wrong, they wont pump.
leave play in the fuel lines until your done, then trim to fit. keep them short as possible with no binding or kinking.
use grease on the carb base gaskets. make sure they arent broke.air can get in there and youll go lean.
set the carbs with stock settings if you have no Mods done to the engine or carbs. unless your at a high altitude
use 2-stroke oil/gas mix to bump start the engine until you get fuel flow thru the carbs.
clean the screens on the gas tank pick ups. make sure they are on.
make sure the lines you use for the tank are straight and not curling up on ya.
1 is your reserve and the other is your main. dont mix them up/ do 1 at a time. 1 is longer than the other.
make sure the return line gets the restrictor put back in. that builds your fuel pressure.
mount the pump above the pulse line. otherwise, it could suck liquid into the diaphrams in the carbs and they wont work.
replace 1 line at a time so you dont get confused.
clean the gas tank out, the oil tank and the water fuel seperator
check your gas tank cap for cracks inside the ski
check the o=ring in the fuel selector
make sure the water fuel seperator gasket is in there and the cap isnt cracked.
adjust idle after to spec. 1250 rpms. it gets adjusted on the end of the carb rail with the tee handle and spring adjuster.
double check that the oil pump is working properly when the throttle is moved for binding
the oil lines are special size. 3mm id and 7 mm od.
check to see if the big oil line feed tube is tight and has clamps on it..
when done, double check that the oil lines are indeed connected and tight from the pump to the carbs.
replace the plugs with br8es NGK only. Gap accordingly. .024-,028".if you want to replace them.
make sure you torque everything down to specs.
check to see the cam for the throttle cable moves freely and opens the carbs all the way open when you hold the thottle open all the way.
Fill the water serperator with 2-stroke oil mix and gas to get it up n running. that way your not sucking air until it fills up. makes it start quicker.
look to see if the choke operates as intended. it closes all the way when shut and opens all the way when open.
Fire it up! Look for leaks..
if your worried about oil consumption from the oil pump working properly, you can always add 2-stroke oil and gas to the tank and run it like that untill your sure the pump is actually pumping oil and you see the level go down. might smoke a lil more than usual..lol 40/1 mix.
add the gas first or else youll suck up all oil first and it wont start..
throw away the auto cock. it looks like a lil fuel pump. it doesnt go back in with the new routing.
Nothing will change really when you replace all this. it will just provide the correct fuel flow from now on. Good Luck! takes about 3 hours total. about 200.00 for everything.
You could even replace all the needles and seats in the carbs,the orings for the needles and replace the fuel selector o-ring if you so chose. if they need to be changed.
Tired of reading? Well start wrenching! bring some soap and water with you.. that oil is slippery and hard to get the lines on the fittings. I use it to wash my hands and to lube the ends of the lines to get them to go on. I use a small pair of pliers to open the ends of the lines a lilttle to get them to go on easier.
