Top 20 2002 Yamaha V Star 1100 Custom Questions & Answers

I would check if it still has stock jets. you need stage 1 or 2 dyno jet kit. To get best out of that upgrades also look for any vacum leaka

have you compression tested the cylinders ? if you dont have a gauge you can remove spark plugs and put your finger in plug hole and crank over and see if it blows your finger out ! could have bent the inlet or exhaust valves as well as the piston !

Check your neutral switch wire. and also the kick stand switch.

if its a constant wining sound a bearing or cog is worn and needs sorting b4 it fails

You need to check if there any bad grounds, if you have any aftermarket lightining those may couse killing the battery. or have your battery checked or tested.

I have a 02 Yamaha 1100 custom right turn signal indicator in speedo housing always works but the left turn in the dash takes spells and doesnt work but the turn signals work fine not sure if its the turn signal relay or not

Have you done all the regular stuff? There are a number of interlock safeties on this bike. To start, key on of course, side stand up or in neutral, if in gear and clutch is engaged, it will not start, if the kill switch is in the off position, it will not start. Said differently, you must have the key in the on position, side stand retracted, transmission in neutral, clutch pulled in, kill switch in run position. Still will not start, check the start solenoid for proper operation. If that works ... suspect the starter motor.

remove the neg cable and place a test light between cable and post and see if light comes on,if so then start removing fuses until it goes out that will narrow down your problem, if the light does not come on have the battery check it could have a faulty cell

Idle screw is on your carb/carbies

But did you also change the spark plug cap? It unscrews off the end of the wire . It should read 5000 OHMs any reading higher or lower and you replace the cap. NGK caps run about $5 each . I always recommend replacing them as a set.

Pdf format, full color and instructional, happy fixing

u need a repair manual for starters--if oil is gritty its time for change-or u may just get new filter--straight 30 wt is good--the front bottom will be cooler cause of air flow-top has diff fins and combust is there--body care is like cars

Maybe ebay.com.

problem is probably the fuel petcock try this test disconnect the fuel line and get a good length of clear line enough to reach a container hook it up to the petcock and turn the petcock in the on position and observe the flow of fuel to see if it is flowing freely try this in the on and the reserve position.
if it id restricted remove the petcock and clean the obstruction of rebuild or replace it.

Have the battery checked. may not be holding a charge and is discharging during use. all seems to point to poor batt status

Hi and welcome to FixYa,

To your query, there are 2 major components of the charging system:

• stator - left side of the engine itself;
  
• regulator - right side, below the seat; would be behind the chrome cover below the battery.
  

A common problem with a VStar is burned, pitted or corroded terminal pins/connectors from the stator to the regulator.

Good luck and thank you for asking FixYa.

Just remove the left cover. The stator is bolted to the cover on the inside. Could you take a moment and rate my answer? Thanks!

your voltage/reg. can be tested in a couple different ways check ground res. check res. then revs. bias on diodes you have ac in dc out it sounds like you may have a diode gone bad allowing ac curent to flow causing the wires to get hot

Common problem with poor quality parts, the regulator is the problem, the generator is working other wise you would not have fried the wiring, you answered your own question. someone telling porkies to get more money from unsuspecting client?
The regulator controls the voltage not the generator, the generator only supplys the voltage it cannot overcharge unless the regulator is not working properly, simple!
