Question about Yamaha YZ 450 F Motorcycles

1 Answer

My yamaha yz450sex 2008 dirtbike is not running very smoothly. Slightly hesitant under quick acceleration. What can I do to fix this? It feels like it's restricted somewhere - had plenty of 450's before - this one just doesn't feel right.

I am not familiar with the 450sex? model. If it has a carb with a slide and jet needle then remove the slide and move the clip on the jet needle down one notch. This will richen the low range fuel mix.

Please rate this answer. Thanks gatecrasha!

Was having a slight hitch when accelerating up hills then the other day my cat got red hot and it would barely run, now i fixed the cat problem but it wont start, any tips?


When the engine really got hot is there a possibility you may have over expanded some parts and now the engine is sort of tight and is not spinning fast enough to start.

Check for spark and fuel delivery but ......................

My 2008 Equinox hesitates and jerks when accelerating beyond 45mph before running smoothly again beyond 55mph. The engine light flashes when accelerating beyond 55mph with a slight hesitation. I've...


Sorry Cleef, on dial up and lost the connection.
The reason it does this at higher speeds is that more ignition spark is needed to fire the spark plugs.
Yes, it's time for a tune up.
A shop that has a scanner can identify which cylinder is causing the misfire. It will have stored a code to do this.
I hope you find a good expert on chat. If not, message me back here and I will help you find your problem.
Again, my apologies for my poor connection.

your honda has a fuzzy logic/computer operated gearbox.(auto)the first 1/3 of the accelerator pedal is for economy/smooth changes.the second 1/3 is for "normal"? driving and the last third( is for idiots like me,power crazy) is for quick passing.i am assuming you have not had this explianed to you by the salesperson, yeah right, like they would....all this is controlled by the onboard computer....if it had a fault it would show ..

2004 dodge caravan 2.4 Hesitates during Acceleration and at idele


You should definitely replace the fuel filter though this probably won't fix your hesitation. It wouldn't hurt to replace the spark plugs this is usually the culprit on these engine. I have the same engine in a '99 caravan and found the for some reason the spark plugs on cylinder 3 and 4 loosen up after one year and cause a misfire between 45 and 50 mph under load (when mildly accelerating).
