Re: Carb Tuning

Hi guys, is there a way to know if the engine is running lean or rich without checking out the spark plug? Asking because started using Motul 5100 10w50 on the RTR 180 recently. It feels very sluggish and jerky at times.

Approved and merged!

Carburator swap between bikes

My fz carburator is giving some trouble.There are scratches on the piston valve of carburator.

I am from Nepal and the carburator of fz costa 3 times more than that of apache.
My friend is using pulsar 150 carburator on fz
And says bike is doing fine.
So is it safe to go for carburator of other bikes which use..mikuni bs 26 carb which is stock carb of fz.

Atleast does the carburator valve piston of other bikes can be used on fz?

Re: Carburetor Thread

Then engine will be tuned to comply with emission standards.

We want optimal engine performance across RPMs (1/4, 1/2, 3/4, WOT) also complying with emission standards. PAIR/CatCon system takes care of most of the unburnt A/F mixture, doesn't it?

Damm
I didnt think of that:P
Hmmmm,
Makes me think there should be more ways ehh?

Cant we use the pollution guys to test the exhaust gases while we adjust the carb according to their readings?

When it comes to rust it always finds it way into the metal or onto the metal nothing can stop it, (like corruption in our country hehehe),

Re: [UT]: Tuning your Motorcycle Carburettor.

Well i don't want to cut my tank, because that will ruin the tank because then i have to reweld it, i don't think that any welder in delhi would be having mig welding,plus i have to repaint it, my bike tank paint is very good even after so many years what i was thinking of an electrolysis, or the simple kerosene wash with some old nuts and bolts, the silicone treatment that you are talking what is it pls throw some more info on it.

Silicone cream like substance called tank treatment was available I dont remembr the brand very well costed 130 rs for 100ml. You put it in ypur tank wh shoukd be clean and dry and move it around whennthe tank is hot.
It sticks to the tank walls and hsrdens up and prevents rusting. Kind of painting the insode with antirust but normal paint will dissolve in petrol
This wont.
Electrolysis yes I frgt u can have a go at that too but I think its not always usefull.

Re: [UT]: Tuning your Motorcycle Carburettor.

Well Abhishek sir. I need a small clarification about the jetting. Let me explain the results after I did the jetting to my carb. I am using a Suzuki Shogun and carb is vm20. I changed the main jet from 100 to 110 and the pilot jet remained same 20. I didn't find and any power increase in my bike but faced some problems like the bike is taking more air when it is in idle and felt almost like shutting the engine. Air mixture was very high when I started my bike after the full throttle run.

Now I have an idea will my bike gains more power if I change the main jet 110 and pilot 22.5 or 25.

Please reply

Re: [UT]: Tuning your Motorcycle Carburettor.

And if a tank is already rusted then what can be done to save the tank, my bikes tank is also catching rust from inside, newer tanks are galvanized but not the older one, so is there any remedy for my tank bro.

Surface rust of a tank is very easy to remove and fix.
The rust on the inside is usually a tank killer. There isnt much you can do without cutting the tank open and welding it again and repainting.
Sandblasting from the inside helps but tanks are made of such thin sheet metal its difficult and can deform a tank.
Try cutting the botton of the tank and cleaning it from the inside then weld and paint it from the bottom. Be sure to get rid of all petrol traces before approaching.
