Im back another problem =( Blaster acting very strange.

[EZRider76]

get a flashlight and give that piston a look in the intake, rotate the crank to get the piston up to where you can see it all, look for scarring and gouges, light scratches will be fine

i use high temp copper perma-gasket in a tube, a light coat on both sides of the intake gasket and the intake itself where it seals to the reedcage
just a light coat, not globs that will squeeze out into the intake, let cure before running it, overnight is best

do not over tighten those intake bolts, main jet, pilot jet, or carb bowl screws, they all luv to strip very easily
skip your wheaties that morning, LOL

and be sure to put the brass washer back under the main jet, then slide the white plastic splash gaurd down over it

I will need to see pics of that, I have no idea what you're talking about with the washer and the splash guard....could it be my carb just didn't have them?

Thanks for jumping in too, I was trying to be very meticulous with my description. I'm definitely going to have to add that carb cleaning routine to my sig so I can find it for reference.

not sure all carbs have the brass washer under the main jet, you will have jetting nightmares if that is called for but missing !

Alright awk well idont have any sealant at the moment can i pick it up at an auto part store... i might have to watit ill tomorrow i gotta change the car oil an go to a birthday party but im gonna try an get around to it tonight for sure... An shoudl the bike warm up before messing with air screw?

 

[Awk08]

An should the bike warm up before messing with air screw?

yes, warmed up, turn the idle screw on top of the tors box slightly higher so it stays running while adjusting the air screw, remember to allow 15-20 seconds between turns to allow the engine to "catch up"
after finding the high idle # of turns, shut it off, turn screw in while counting the turns, so you know how many, then return it to that exact position, and play with slight 1/8th turns one way or another till it revs clean to about 1/2 throttle

 

[gb blaster]

seems simple enough to adjust an the tors box idk waht that is how do i tell if i have it or not alot of people have taken theres off i seen why?

 

[gb blaster]

an about that sealant where would i purchase that i dont wanna cut any corners would like rtv or something form autozone work i no u can use that for head gaskets on a car.

 

[Awk08]

you can just delete the tors electronics to avoid future problems, or eliminate it completely with a tors delete kit

it's the big boxy lookin thing on top of your carb, with wires and throttle cable going into it, the idle screw is on top of that, accessed under the seat, lift the rubber flap, and look under the fuel tank, you'll see a large screw head, thats the idle screw, if the tors box is present

Right! We're here to help...and to make fun of once you're comfortable...but mostly to help.

The Sealant AWK described is an RTV, just has copper flakes in it, and is High Temp...we all use it. Good luck and keep us posted, if you have any questions, stop what you're doing and ask, we will help. If you really want good advice, a PM is great because then you don't get 5 guys answering your questions and confusing you...just sayin. Also, don't get frustrated, we've all been where you are, before you know it you will be offering advice.

You can leave it off while you're waiting to get the stuff around. Of course I'm assuming it is in the stable and not out where it can get rained on. The only thing you might have to worry about is rodents, they might find it and make a nest in there...or mud wasps. Just put the reed cage back in and start a couple of the bolts...a few turns in. That will keep it in place and pests out....better safe than sorry. Good luck and glad we could help.

 

[gb blaster]

in the garage of course lol no rodents either lol but ill still keep in on the bike with all bolts slightly in keeps everythings to gether prevent loss thanks

Yes, the leak test should come first, before you start it to make other adjustments.

 

[gb blaster]

Bout to go see a movie for a freinds b day then I will probly do the Carb.... but I'm gonna take everything apart an clean. Fix. Or whatever then put it al ether leakdown test the bike an tune the air screw an then plug chop should be done correct?
