I have a 96 suzuki savage that started out with some lifter noise. when riding into work today it ran fine the fist 5 or 6 miles then it loss power in all gears it seam to idle fine and didint backfire.

It may be the kick stand safety switch? You can only start it sitting on the bike with the stand up.

Sounds like vaporlock. Try insulating the fuel line, especially around hot engine parts.

what engine the V6
did you read the TSBs on chain noise of lifter noise.
how many miles on engine? 100k, 500K?
not changing oil frequently dooms most HLA lifters. they gum up and click (collapse)
same with chain
same with the tensioner,
a good tech, can find which part ticks with a $5 stethoscope.

No, change the speedo cable.

Sounds like you need to get your carb serviced i.e. cleaned and setup correctly.

Lifter tapping.

There is a tendency for you tohear some noise because they are normally pretty quiet, but just in case you didn't check it out put your hand on the gas cap cover when going down the road.They vibrate after awhile> you might try synthetic oil also, it does quiet them down.

the car is definately overheating,have it checked out soon

try the connections on the starter and the solenoid they could have corrosion which will affect the starter.if they are corroded just clean them up with a wire brush.

sounds like either the battery is past its useful life (will no longer hold a charge while under load) or the recharging circuit is no longer working. i'd focus on the battery especially if its the original from 2002.

even if the trickle charger shows a full charge, remove it from the charger and immediately measure the voltage. wait about 10 minutes and recheck the voltage. if it has fallen to below 11volts without any load applied, then change the battery. be sure to trickle charge the new one before using it.
