why does it die?

[rugabugadouglas]

i have a 79 110 and when you shift into gear it dies unless you are on the throttle or give it a rolling start then shift what would it be a clutch prob or hi/lo gears? it does it in hi and lo so i dont think its that but not sure? would a tight drive chain cause andy prob like that too? mine might be too tight. thanks doug

You should adjust the clutch first so you know its starting to engage at the right rpm.
I would also clean the carb out so you know the pilot jet is clean.Clean out the fuel strainer also at this time along with the air filter and oil it.Adjust the fuel screw to spec also and set the idle.All this stuff can effect your idle and off idle running.
Adjust that drive chain and oil it to so you dont ruin it and the sprockets if its too tight.If its too tight it shouldnt kill the motor.Im sure its not all this stuff ,but its routine maintenence and should eliminate your problem.

well the motor is just rebiult the carb is new today and runs great and through all the gears and the chain and sprockets are also new but the clutch is used off ebay should i try another clutch i have? i adjusted the clutch according to the book turn counter clock wise till tension then back off clock wise 1/8 to 1/4 turn?

[dufrain]

Sounds like everything is good .Did you adjust the carb like the manual says with that air screw.When you put it in gear does it just kill it and engage real hard like something with a manual clutch

[rugabugadouglas]

kinda once in a wile if you put it low it will go but acts like you dump a manual and it kinda jerks and then dies i think the carb is ok cause when you get it going to takes off good good power and idles fine i was preset when i got it it is a 24mm mikuni with a 95 main jet in it i might try plug chopping it this weekend with a new plug but any other good ideas would be great

Sure sounds like everythings ok but that clutch,I wonder if it has any rust on the surface of it.Id put the front wheel against a tree or something and slip it for a little and see if that helps

[rugabugadouglas]

if im off the machine it will take off ok to a point but i try to kill it so it wont end up down the block so it seems weight is the problem will puting it agaist a tree help mabey? it does seem like it slips a little going up hills in the snow?

[dufrain]

if its slipping going up a hill its either worn out or adjusted wrong,If you put it against the tree it will slip the friction plates on the surface and clean off any rust .

Theres a clutch disc set on ebay for 22 shipped ,Id put in the heavy duty springs if you redo your clutch.I put them in my 250es and it shift alot quicker now,a bit like a shift kit in a car.

[rugabugadouglas]

ill try that tomarrow and see if it helps it sat a while and that migh be it i didnt look at it too well before i put it together so who knows if it doesnt work ill adjust the clutch again. is there a good way to do that? go tighter or looser? do it running?

[dufrain]

My book says with the trike not running,loosen the locknut,turn the screw one full turn clockwise,turn the screw counter clockwise until resistance is felt,turn it back clockwise 1/8th turn,Hold the screw in place and tighten the lock nut back up.

[rugabugadouglas]

ill try it your books way cause mind doenst seem to work

[rugabugadouglas]

well i think it worked i need to do some cable work the new carb doesnt have a threded cap so i need no make it so it wont jump out of the little holder the rubber sleve isnt holding it too well is there a way to shorten cables?

[dufrain]

I dont think there are any threaded adjusters on the the thumb throttle housing .Can you use the old carb cap

[team-red-rider]

hey doug did that cam work out for you?

[rugabugadouglas]

i havent put the cam in yet got way too many projects going on one i get it going good ill prob throw it in. the old cap fits i just need to put the cable in it have to watch the rugrats for a few hrs then ill know if it work

[team-red-rider]

u interested in trading more 250r parts ??
i got more stuff now

[rugabugadouglas]

well it rund good now shift with out killing better still think there is some rust on the clutches but alot better i had to add some length on the inner cable to make it idle lower still a little high but i might have a air leak ill have too look at it closer later tonight

[traxxasx]

you adjust the idle by a screw with spring on your carb not by the cable. It seems to me that it wasent broken in yet and was to much at the time, now as you have it running its breaking in.

[rugabugadouglas]

yea that might be it whats a good way to check for air leaks? it idles high even with the idle screw turned out a ways sould i let pressure off the cable? its at about a 1/8 throttle idle now i would guess

[dufrain]

Did you set the air screw to spec.You can turn that idle screw all the way out until it idles where you want,its just a throttle slide stop.If you suspect an air leak just take off the intake and carb and inspect the gaskets.If you put in new ones they should be ok.I cant remember if the 110 has the oring in there like the 70 does or not.If it has an air leak the plug will be real white.

[rugabugadouglas]

where is the air serew on this carb thats what is on it http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ih=002&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=120073442722&rd=1,1

what does the air screw do for me exactly ive read the form but dont get carbs that well

[team-red-rider]

u get my pm doug?

[dufrain]

Ok on the throttle cable,the tip of the lever is supposed to move at least 3/16 before the slide starts to move up,from completely closed
.On the carb and high idle thing ,I think your problem is that mikuni unless you can sort out the throttle cable adjuster.You also dont have the adjustment specs for that carb so its all guessing.
If you have the stock keihen ,both adjustment screws are on the same side as the petcock.The one lower and toward the front is the air screw.The one in the center of the slide tube is the throttle stop idle adjuster.Turn the air screw all the way in lightly and back it out 1.5 turns ,then set the idle with the idle screw to a smooth low idle, unless you have a tach to set it to spec.Now screw in the air screw until it dies, then back it out 1 turn.Now do your final adjustment on the idle speed with your idle speed screw and its done.

[dufrain]

I dont think that Mikuni has an air screw,you probably have to change pilot jets for low speed adjustment and the main is probably small since thats probably jetted for a 50,I would email them for some jetting advice

[rugabugadouglas]

its a 92 main jet i looked before i put it on
