Any steamer owners in MN? with carb genius?

[DWNUNDR]

Looking for some help with the bike... ran 95% fine since I had it... I store it in a heated garage all winter.... but forgot to start it regularly..

this season it has run like it was on 2 cylinders... tried seafoam.... like 3 cans haha.. finally pulled the carbs out today, stripped them down as far as I felt like.. blew out as many passages as I could see... ran a drill through the main jets by hand.... cleaned all the airboxes up, sealed the joints on the right side with silicone...

put it back together and the choke is really hard but can work ???????? nothing seems to be restricting it...

the throttle sounds a lot more responsive than it did before tear down, but when I ride it... rides like sh*t... I mean it runs... but not as much oooomph as it should have... the torque doesnt even kick in in first gear.... used to spin the rear wheels (I live on gravel roads) in the first couple of gears once it hit over 4000rpm...

It always since I got it had that dead spot under full throttle until it hot around 5K then opened up... but was fine if you rolled/feathered the throttle....

now it just sounds wrong... almost sounds like its not running right on cylinders...???? like there is an exhaust leak but I can hear it once down checking at the outlets, but the main noise sounds like its near the bottom rear of the engine...  I am so stumped now...

loved this bike till now.....

mikunis ?

it's your pilot jets and pilot circuit .

did you take the pilot jets out and verify they are not clogged by at least looking thru the tiny little hole ?

your carbs are not clean yet ...guaranteed .

[DWNUNDR]

pretty sure I did... I blew thru them, then held them up to the light....

I was soooo excited as it sounded more responsive only to run like poooooop

I studied all your posts mustang regarding these carbs... hence the seafoam route...



guess I may have to take them off again....


mind you I am researching different bikes... might be an excuse to move on haha

[DWNUNDR]

So can you spot the issue with this picture???





yep... dont remember noticing that middle spring/washer/o-ring not there when I first went thru it.. oh well.. gotta place another order and pay more for the shipping then the parts from bike bandit... hohum

[DWNUNDR]

seeing as I work in a machine shop (out of school a yr ago for cnc) I figured why not see what we had at work, so I took the jets in and ran them in the ultrasonic cleaner for a few hours, made my own pilot jet spring out of an almost exact match piece they had at work, made my own washer for the pilot jet and dug up an o-ring as well... saved me about $40 woo hoo


she fired up... but I am replacing the clock with a blanking pc that will hold a power supply... planning on designing and machining something at work tomorrow to fill the clock hole (clock stopped working)...

so hopefully the rain will clear up on the weekend and I will button it all back up and see if it actually runs...

I turned the pilot jets back 2 turns... by two turns I mean the same side of the screwdriver does a full 360* turn (is this correct mustang?)

[Mustang]

depending on your pilot jets you may find 1 1/2 works better on the mikunis

but yeah 1 1/2 to 2 turns is good starting place

[DWNUNDR]

So if I have run a acetylene torch cleaner through EVERY orifice (on the bike :) ) I could see, ultrasonicly cleaned all the jets... re-installed and it seems like it just doesnt have oooomph.. admittedly I just rode up and back along the dirt road about 1/4 mile... tomorrow if it is dry I may take it for a good ride and see..... but would having the jets out 2 turns do this??

[Mustang]

no

[DWNUNDR]

well I am lost now... 

been updating in the other thread (DAR)


SYMPTOMS:

Starts real easy.. idles fine though there is a noise which sounds like metal rattling or misfire? (was louder not as loud now)
Revs fine in Neutral (seems to be smooth)
First gear seems ok till it hits around 3500 rpm then the power just flattens... engine revs up but no big torque kick around 5K and no real acceleration....
2nd Gear the same as first..

never tried higher gears as I turned around and parked it...




But I am lost now...

so far I have had the carbs apart twice... 
cleaned anything with a hole thru it... literally... (Mustang the circle on the pics are the jets I cleaned out including the ones in the front (where it meets the airbox) of the carb that unscrew...
I used an oxy torch cleaner thru passageways (ie like a file but wire shaped),
carb spray cleaner,
ultrasonic cleaner at work on jets etc,
high pressure air thru it all,
ran drill bits thru jets by hand,
cleaned fuel filter screen between 1 & 2 carbs....
the tank was emptied before carb tear down as I ran 2 cans of seafoam thru with almost an empty tank...
fuel line from petcock to carbs has been replaced
spark plugs replaced (never did #2 yet) and I am sure that will end up being the bad one...
I have switched coil packs around trying to determine if a coil is bad (no definitive conclusion)
I did have one of the tops of the carbs off whee the diaphragm is... it popped out of the grooves... I think I got it back in right.. the needle and slide thing seem to have some pressure when moving it up and down?!?!?! but it was a little oversized where it sits in the groove.... had to finagle it to get it sitting in right... would this cause the misfire or unpowered feeling??


The only thing that was wrong with this bike when I stored it for winter is a small flat spot between 3-4K and only under hard acceleration, if you rolled the gas on it just pulled all the way until red... and it sits in a heated workshop all winter... longest it sat between starts is when I went back to Australia for 5 weeks so maybe 2months between starts... never bothered it the previous year!!

now it doesnt seem to have the torque and pull to it after 3500rpm... just flat lines... (it seems)

could the float o-rings cause this??  they all seemed in great shape... so I never replaced them..

I really dont know where else to look.... I am not in a rush to tear apart the carbs again but after this I know if I need to it takes me about 30mins to get them all out and on the bench...

I truly am stuck... and right now I would rather just trade it in and get a touring BMW with fuel injection.... but on teh other hand I really enjoy riding this bike a lot... went form a TL1000R to this and it was like a stool to a lazy boy in terms of comfort and enjoyment to ride...


I just want to ride...


next step may be to drop it off somewhere.. but am trying to avoid spending $1000 on a $2000 bike at a shop!!!!

now that you have finally given a decent description of problem........ sounds like fuel starvation

remove petcock from tank
make sure there is no corrosion blocking the flow in the tap
check main and reserve

remove both nylon filters
reassemble with out the filters
remove the filter thats in the pipe inlet in the carbs end
install a inline filter in the gas line

if still dead above 3500 rpm
is the right hand snorkel capped ? it needs to be !
try going for ride with gas cap open your vent may be clogged
also if you have water in tank can do this but you will have solved that by removing petcock.

Hi guys,I took your advice Mustang,and fitted 42.5 pilots on a spare set of carbs I had(with 105 mains). My bike has a K&N filter. I fitted the snorkels off my Super 3,without the blanking cap. My bike runs superbly! Pulls like a train and mpg has improved. Could o rings be his prob?

remove petcock from tank I remember reading something about reserve working for someone else so when I turned it to reserve it seems to sound quieter but then it still ran funny)
make sure there is no corrosion blocking the flow in the tap will do although it seems to piss out pretty good with no hose attached
check main and reserve will do again

remove both nylon filters both?  where are they?
reassemble with out the filters
remove the filter thats in the pipe inlet in the carbs end guessing I may have to removes carbs to access this again?
install a inline filter in the gas line will buy one tomorrow

if still dead above 3500 rpm
is the right hand snorkel capped ? it needs to be !YES
try going for ride with gas cap open your vent may be clogged attempted - no change
also if you have water in tank can do this but you will have solved that by removing petcock. I had drained the tank totally before cleaning carbs - ran straight seafoam then added some gas so I would so no water

also there is a metallic sound when releasing the clutch... like the typical steamer rattle only LOUD.. any ideas? sprag clutch? clutch itself? DAR?

The two nylon filters are fitted to the main and reserve pipes on the actual fuel tap, so remove tap, then remove both nylon filters.

The filter is in pipe that goes from the petcock to the carbs, at the end towards the carbs. I replaced it too with an inline filter, it's easier to spot and change when dirty.
Mine was also rough running - got fixed after I realized the wire connection to one of  the coils was interrupting from time to to time, due to the vibrations. So the coil was functional, but had its bad moments. I simply flattened the connector to hold better to the coil.
My tiger also had problems accelerating over 4000 rpm, the air box was cracked, fixed after changing it. Make sure the rubber gaiters between carbs and engine are not cracked or smth, it might suck extra air through that.

The filter is in pipe that goes from the petcock to the carbs, at the end towards the carbs.(yeah I knew about that one as I cleaned it out when I pulled the carbs apart last time... too busy this weekend with other chores so put the bike aside for a bit to cool down and re-energize my enthusiasm haha) I replaced it too with an inline filter, it's easier to spot and change when dirty.
