bikes completly boggy

[89mustang]

alrighty well i have recently rebuilt my whole engine. bottom end and upper end. everything stock in the lower end except a wesoce crank and rod. the upper is bored .040 over with a weisco piston along with a dg full pipe. and also put tors eliminator on it. and an adjustable stator plate. well since i have built it is completly boggy as hell at ideal. if i put it to wot is dosent move the rpms at all. dosent go up at all. now before i rebuilt it it ran fine untill i some how got mud in the motor and the crank bearing froze up. i have tried to adjust timing but dosnt help. dose the same thing. i cleaned the carb and every thing. any one got any ideass???

for one you want to take that top end back off and look at the piston, rings and walls of cylinder becuase its important that the piston is sealed closly to the walls and it will seem as if the piston is fine looking from the top until you follow those steps even though if you put in a new spark plug it will go to running back fine i promise but by me not knowing the first time it even boggs down and theirs gas you should hurry and change rings because if you dont you will be replacing a whole new piston

 

[Awk08]

have you tried a new spark plug ?
was the piston installed in the correct direction ? arrow facing forward ?
was it leaktested ?
compression test ?
have you eliminated the TORS ?? and parking brake sensor (03+ only) ?
all wiring reconnected correctly ?
ground at the coil on clean bare frame ? (black wire)
take the pipe off the cylinder and see if it reacts
report back

whaaaaaaaaaaattttt ?????

 

[89mustang]

to answer your questions, i have tried a new plug didnt help, the piston was installed correctly i already tore the head and jug off of it once, it has not been leak tested, compression test has been done. its about 100 which is low but figured it would jump up after the rings seat, i have eliminated the tors. wiring is all good i cheaked it all over, and the ground is good. the pipe i have not tried yet. and that trouble shooting list i already did it.

i'd check the flywheel woodruff key next, to see if it has slipped and may be sparking, but at the wrong time

Awk, I think what he is saying is that, he does not know what he is talking about!

Have you done heat cycles, and break in proceedure, I am assuming that you have because you have tried WOT,.

What is your jetting?

Do a leak down test and tell us your findings

 

[89mustang]

the woodruf key is brand new and is in the right spot nothing as slipped. i cant figure this thing out. i was thinking the cdi box might be going bad but idk

 

[Blaaster]

What year model is it?

There are differences between pre 03, and need a different method of removing the TORS.

Re check the parking brake if it is +03, it wont go more than an idle with a fault there.

Have you done a leak down test yet, pressurise the carb boot with the exhaust blocked off.

It should hold 7psi for 10 mins.

What is your jetting..

If you have a carb clean, jetted and adjusted correctly, fuel flowing, and it is air tight, then the problem should lie with the electrics.

 

[89mustang]

its an 01, havent done a leak down yet cause i dont have the right leakdown tester yet. main if i remeber right is like a 320 or something.

 

[Blaaster]

A #320 is way too big for a DG, it could be covering up an air leak.

Another thought, if there is no air leak the large jet could have allowed the crankcase to flood with fuel.

Take the plug out and see if it is very wet.

If it is turn off the petcock, drain the float bowl, hold the throttle wide open, and kick the living daylights out of it 20 or 30 times to purge the crankcase.

 

[Surfrjag]

check the reeds and make sure a jet hasnt come loose and fallen out into the carb bowl

 

[89mustang]

alright guys i have tried a few things to see if i cant get this thing to work. i have switched my reeds with my buddys reeds but it ddint change a thing. i switched my carb with his carb he has a 250 jet and it didnt do a damn thing. put new plug in it didnt do a thing. and i had the 340 jet in the motor prior to the engine build and the thing ran like a raped ape. so i cant figure this thing out at alll.

it's gotta be an airleak or electrical then
leaktest
remove pipe from cylinder and see how it reacts (clogged-pipe/silencer)
check for good clean, bare metal gorunds, especially the black wire at the coil mount
check all electrical connections
swap cdi and coil from your buddies
check flywheel woodruf key is intact and aligned

If a DG was running as you say, with a #340 main jet, it's gotta be an air leak, or you were using carbonated water for fuel!

If a DG was running as you say, with a #340 main jet, it's gotta be an air leak, or you were using carbonated water for fuel!

So, would that be considered a main hydro conversion if it is running on carbonated water??

Seriously though, let's break it down simple, is your air filter or anything going into the carb clogged? Is the exhaust clogged? If you are giving her all she's got, and she's not screaming, something's gotta be choking her. This could be a stupid question too, when you have the air box off and play with the throttle, do you see the carb slide moving? You could have a broken or stuck cable. Check in your throttle box, see if that little nut came loose and the mechanism is moving properly.

 

[89mustang]

i tired to remove the pipe and it did the same thing. the ground is good. all electrical connections are fine cleaned them all. i swaped the cdi and it didnt change i havent tried the coil yet. the fly wheel is fine. and so is the key. the stator plate is adjustable and i dont really no where to set it but i have tried it retarded and advanced. still the same both ways.

and as far as the slide it is going up and down.

now for the exhaust i am going to try to just take the silencer off because i thought it if you take off the part that bolts to the clyinder then you lose the compresion cause that is the exspaninsion chamber.

 

[Awk08]

no loss of compression from removing the expansion pipe from the cylinder,
and i only suggested it for a short time period to verify it is not clogged, just for a quick start-up, and few revs to see if it reacts differently
there is a cone shaped cast iron baffle in them that has been known to come loose and semi-clog it's flow, and mice nests are common if the pipe was left laying around during a rebuild

 

[89mustang]

yea i only took it off for a few revs. and it was siting around for a year but i honestly highly doubt a mice nest got in there.once i get off wokr im going to try and just take the silencer of. and also if the coil was bad that means that under a load that it wouldnt give me a hot enough spark to burn correct? becuase the bike ideals like a freaking beast.
