Your bike has 4 carbs and they are not in sync with each other. This requires hooking a gauge to each carb individual and adjust till each one is exactly the same as the next. The imbalance can be from mis adjustment of just dirty carbs. You will also have balance problems if any cylinder gets lower compression.

2006 v star 1100 classic w/ vance + hines slip on exhaust. I get popping at idle and decel (i'm thinking it just needs to be rejetted). The big problem, is when the bike has already warmed up (at least 5...


The popping at idle and deceleration (when the throttle is in the idle position) could be a lean mixture at idle.
A lean mixture sitting at idle for a long light would cause the engine to run hot.
Also, as the engine reaches operating temperatures, the idle will pick up.

Hi Gdknaff, take a ride or trailer your bike over to your local dealers service/parts department, I'm sure they will be happy to take your Harley Davidson for a test ride if necessary/possible and offer professional advice and assistance concerning your issue. Good luck have a nice day.

I have an 04yz450f and there is a slight exhaust leak where the mufflet meets the headers, will welding the muffler to the headers cause any issues? also would this be a reason why the bike has problems...


Just get a new gasket for the exhaust connection. Welding would be ugly, cause the area to rust quickly and lower the value of the bike when you sell it. Please rate my answer. Thanks. tombones49_98.gif

2001 yamaha ttr 250, starts, idles ok, bogs at acceleration


Has the bike been stored for any long length of time?
old fuel in the carburetor will turn to a varnish like residue blocking the jets,or possibly water in the carburetor.

I have an 07 yz450f i need to know how to adjust the carb. i am not sure what screws do what and where the are even located on the carb. the bike has less than 15 hours and is all stock. it pops on...


the screws on the carb are for idle speed , and air mixture, the air mixture it underneath,but it really only affects mixture at idle speed.
you may need to try raising the slide needle, or go up a size in the main jet, do one at a time and keep notes about the changes and results

Everytime i accelerate my car it starts making a squeling noise but when i don't accelerate it stops and then i hit the acceleration again and then again noise starts and i can't seem to find the problem!


Are you sure you don't hear anything like a chirping sound when the engine is idling? Have you popped the hood and listened while the engine was idling? Have a friend sit in the driver's seat while you pop the hood, tell them to press the accelerator and then listen for the squeal. I would bet dollars to donuts the problem is the serpentine belt is worn and needs to be replaced.

Pops out of 1st gear under acceleration.


Hi Buddy
There is not an easy solution to your gearbox problem,it is general wear on the 'dogs' or 'shift drum'..The only other thing it could be is wear on the 'external shift mechanism'.
I,ve just rebuilt a 1996 vn1500 classic whitch had the same problem so if you need any advise or step by step photos please email me at 'pjuma@hotmail.co.uk'
