I would rejet the carbs. I would go one size up on the jets. That should clear up the problem.

My 1995 duati 900ss SP Bucks,Hesatates and misses at all speeds except while excellirating seems to work fine.


the mufflers act to create back pressure and the air filter acts to restrict air intake. the cheapest way forward would be to re-jet the carbs, might be worth getting matching k&n type air filters to match

The previous owner had the carbs jetted I don't know what size he added or whatever. But everything else is stock. The problem I'm having is the bike runs really bad and the fumes are bad when idling but...


Hi there,

The jets are for increased performance but the jets installed must be in relation to the pipe used. An open pipe would require larger jets. If the jets came with the pipe when the previous owner purchased it, then it should work. My advise would be to tune it up, sync the carbs, and time the sparks.

If all else fail, ask the previous owner to provide the stock jets and replace it. Stock jets along with the stock pipe will almost always run the first time. Sync the carbs and tune timing. If you have it all running smooth, from there you can do upgrades like stage 1 jet kit or purchase a performance exhaust.

Please do let me know if any of this was helpful,
I'll follow it up should my suggestions fail,

Engine rebuild and running fine. After a jet kit and carb rebuild engine will not idle. Carbs have been taken apart and gone through several times by several different shops engine has great acceleration...


Seems that the crank/timing settings needs a closerr look than to feel that the carb is faulty.The engine is becoming rougher because the firing angle is changed. I also doubt that the carb /jet kit be replaced back with the original as the new jet is not matching.
Now start the engine and set up idle to more than minimum so that the vehicle does not stall but is somewhat smooth. Now try to advance/****** the timing and notice if the engine becomes smoother irrespective of the TDC settings. If so set to the best level and bring down the Idle , do not reduce off air but check the mixture at the exhaust to have this done all over.
Somewhere in the new change a point has been missed..

1992 Honda CB 750 Nighthawk flat spot coming off idle


Hi, Msalwasser and the usual suspects are:
1. Installation of a different camshaft.
2. Different exhaust system or "STRAIGHT PIPES"
3. Faulty advance curve.
4. Multiple carburetors not in sync.
5. Improperly installed jet kit or wrong kit.
6. Carburetor internal malfunction.
7. Fuel mixture too rich.
8. Fuel mixture too lean.
9. Extremely dirty air filter.

Vulcan 1993 750 backfire issue everytime i let off


This is often caused by an air leak , inlet manifolds, exhaust gaskets into the head or the gaskets between the headers and muffler.
This is assuming all the rest of the bike is set correctly, valve clearances,airfilter, clean carbs

Our Moto Guzi Nevada is surging all the time and has been back to a dealer several times and they cant find out what it wrong with it. · Inspect for running rough etc + put on axone scan tool + test...


I am not a Moto Guzi mechanic but in the world of Japanese bikes the problem would be trash in the carb partially blocking the main jet and / or internal fuel circuits. Tighten all fittings, carb to manifold as air leaks could be contributing to the problem. If your bike has fuel injection, have the fuel pump checked. Be sure the gas tank venting is not plugged whether carb or injection. Check and clean the filter screens on the pickup tubes inside the gas tank. Be certain the exhaust pipes are clear of obstructions. An internal collapse inside an exhaust pipe can restrict air flow. The bike can not run properly if it can't get rid of burned gasses. Remove the exhaust pipes briefly to eliminate the exhaust system as a problem. I guess I should mention the obvious, how clean is the air filter? Bikes gotta breathe in and out too. If these ideas don't help, just re-post the problem and perhaps someone else has an idea. Best wishes.

Because the timing is off. If the timing is too advanced, or too retarded, it will make your exhaust pipe cherry red.
