Carb rebuild dual mikuni sbn38

[trotty]

Just taken the carbs off and need to access the jets but cannot get the cover plates off. Are these thread locked or something?. I feel if I put any more pressure on them I could strip the screw head, Christ this is supposed to be the easy bit. I'm doing it prior to installing a ltd pipe.

 

[Ducky]

I mean...you just unscrew them..

And an LTD pipe? That might give you even more headaches than some screws you cant remove.

 

[trotty]

Lol I know. It's the first time the carb has been taken apart, just put some oil in there and will give it another go in a bit.

hit each screw head with a big hammer before you try and turn them or use an impact driver

I normaly use the right size screwdriver bit and put it in a 1/4 socket with 1/4 ratchet then push down on the ratchet and turn it slow. Works for me and when I think im about to strip it I use and impact driver like buzz said then when I strip it I use a needle nose vise grip clamp and bam!....but then I need to find a screw =/

 

[trotty]

Ok I've done it, poop the bed they were tight.

 

[trotty]

Thanx peeps.

[Ducky]

Well you are not entirely wrong...he definitely makes carbon powerfactor chambers.

Quinc=musclehead LOL

Sadly less and less everyday. Haven't lifted heavy since having a kid. Be lucky to put up more then 3 plates now. =(

Is it my guess or are the hi and low speed adjusting caps that are drilled out to access the designated screws not their on the sbn 2011 superjet because I have looked at the diagram and there's just a dust cap on one and a handle on the other?.

 

[trotty]

Sorry guys, new to this but want to learn ....

 

[TheBuzzard]

to get to the hi and low screws, you will need to cut the ends off those plugs.

 

[trotty]

Ok buzz will have a look 2moz only had a brief look. Thanx bud.

Good time to place an order from @JetManiac

Buy the Allen head kits for both diaphragm and pump sides. Can get nice and tight but easier to get off and won't strip.

Also if removing the stock plugs, he has tee screws for highs and lows.

I bought both of the above from him and have been pleased with the setup.

 

[trotty]

Ok yea I've sent him a message. Thanx

Ok I've looked closely on carb and I can't find anywhere I have to drill. All I find is an adjustment screw for the high (pic1) and a t adjustment screw for the low (pic2). Did they remove tamper caps at manufacture or am I still looking at the wrong thing?. They do say h and l where these are.
