Question about 2008 Triumph Street triple

Revs not dropping when hot drop very slowly

I have 1978gs750. i am running it on 1.15 main jets rather than 1.2. when hot i pull the throttle back and it stays revving even if i drop the throttle this lasts for at leasta few seconds and only drops very slowly. i have checked throttle cables fine and air leaks. could it be over fueling when hot. or maybe the little seals round the main jet i just dont know or would a head gasket cause it

I am glad you know about air leaks. Check the cooling fins for oil stains where the head meets the cylinder. A oil stain means the head needs tightened down or the head gasket needs replaced. Set the valve clearances. Bad jet seals can also be the problem.

Saw starts runs good then when i start cutting it

Hi Jason:
Make and model might help but here's two ideas:
1) Remove muffler and clean it. They can get plugged up with carbon and the saw will run at low RPM but will quit because of excess back pressure when you try to rev it up.
2) Set the high and low speed carb settings. Start the saw then gradually increase engine speed until full throttle. Screw the hi-speed needle in slowly. If RPM immediately drops, back it out until Rpm increases, then starts to drop. Screw back in until peak rpm reached, then starts to drop. Back out to peak, then 1/3 turn more.
Set low speed so engine runs smoothly but chain does not turn.
Hope this helps.

1980 GSX1100 Carburators over fuelling starts fine revs freely at stand still - when riding gets to 4500 revs starts popping and pulling back.

By the sound of your description of the problem which was that at about 4500 RPM under load the bike starts 'popping and pulling back' it seems to me that you are experiencing a lean (not enough fuel) condition. Popping and 'pulling back' are indicative of a lean rather than a rich condition. Revving the bike in neutral does not use much fuel compared to trying to throttle it under load so testing it in neutral does not mean much.

Assuming that it is a lean condition that you are dealing with I would pull the carbs off and then remove the float bowls and check out the float valves under each float to make sure they are not partially gummed up and not allowing enough fuel to flow into the float bowls fast enough to keep up with the demand when the engine is under load. Also check the main jet in each carb to make sure it is clear. All the fuel from about 1/4 throttle opening and above goes through the main jet first but from about 1/4 to 3/4 throttle the fuel is then regulated by the needle jet and slide needle. After that, from 3/4 throttle and on, the main jet is the only form of fuel regulation. Either way all the fuel needs to get through the main jet first except at idle and right off idle as that is the pilot jet circuit so the main jets need to be clean and clear.

Also, as the bike is pretty old, when you have the carbs off you need to carefully examine the rubber intake manifolds that connect the carbs to the engine for cracks and splits. These manifolds should be replaced every 10 years or so as when they split and crack it lets air in through the splits and cracks and leans out the mixture going into the engine and will cause the same popping and 'dropping out' that clogged jets in the carbs will cause.

Will not idle. Will not start hot or cold without throttle 1/4 open. Once started will rev well but when revs drop it cannot be recovered and it just dies. Needs choke wether hot or cold to start and 1/4...

By your description, it sounds like the pilot jet is plugged in the carb. Remove carb and clean thoroghly with carb cleaner and air, making sure that all jet passages are clear. Make sure that washer and "o" ring are present on fuel mixture screw, if so equipped. Make sure float level is correct.

Husqvarna 51 chainsaw will barely run, magnito and carberator ok

Probably need to re-adjust the carburetor jets. They are very small screws in the base of the carburetor. They will be labeled with an "H" and an "L" . Set the low speed first by turning it in slowly until the rpm drops slightly then start turning it outward untill the engine idles smoothly. At that point you can also adjust idle speed. Then you need to be careful here but you need to hold the throttle wide open at the same time adjusting the high speed jet. Turn it in until the rpm drops then slowly turn it out. The rpm will keep increasing. Once you get to a point where it is max'ed out then screw the jet back in one half a turn. Changes in altitude like using your chainsaw in town versus going to the mountains for firewood can sometimes make it necessary to adjust the fuel/air ratio.

Idle problems after throttle is closed fast.

sounds like an overly rich condition when you let throttle snap shut no air enters or at least minamal air enters the engine and with to much gas the engine will bog down until the extra gas burns off(5 seconds) check floats height and make sure jets are secure and make sure the choke is all the way off

Slow deceleration in neutral

it revs fine but then backs down to idle slowly. Cdsracer mentioned that his cousin's in SoCal also does this.... Is it due to the different dirtbike clutch basket size? Any idears? Something simple maybe?Mine both drop right back down. Sometimes a slight hover at 2200 RPM or so then settles at 2000 RPM (usually only before motor has fully warmed up) ,,,
