The large 3 wire connector would have been for the reverse resistor assembly.

Possible yes probable no. Surging is a classic case lean condition in an engine which can be easily verified with the addition of a spritz of carb clean spray into the carb intake air stream. If RPM rises and smooths out it is lean.

Use your '94 starter, alternator and carbs. Intake manifolds will need to be swapped because of changes in vacuum line ports. Water pump will have to be changed due to bypass hose changes and the gear sensor behind front cover will also need to be installed off the '94 into the '88 engine.

There is no clear cut easy answer 90% of the time when trying to track down a driveability concern on the 1500. For a successful repair one needs to diagnose the condition to a particular component or system as to the cause. For starters one should always do a compression test on an engine especiall...

The plenum where the carbs attach carries fuel in passages and needs to be looked at as a leak point.

My primary responsibility is to dis-spell these fantasies that appear on the Internet from a guy that might be a WalMart basket collector, follow my drift?

I have the same problem on my 97, though not to the extent that you do. If mine sits for (rarely) 3 weeks, I have to repeatedly attemp starting. It became apparent to me that the fuel in the carbs was evaporating, causing a need to refill the carbs. Since the bike doesn't have a fuel pump ON functi...

To the evaporating gas theorists, no way. The 1500 is an emission controlled EPA and CARB certified MC that would have had to be SHED emission tested during the production run and as such there would be no evaporating gas from the machine skewing the results. Internet Myth. One vocal guy who thinks ...

I installed a new E4 on my buddy's 2000 se and when driving behind him i can hear the tire humming. I checked the tire and there are no marks or and signs of rubbing. The sound changes when driving over different surfaces from a loud drone to nothing. I just replaced my 99se rear with a new E4 and ...

One has to question why this evaporating gas theory is a recent phenomena for hard starting. Where were all the posts and complaints to dealers during the production run which ceased 20+ years ago and is only now put forth to substantiate an unacceptable issue. I have rebuilt over a half dozen 1500 ...

Evaporating gas after a week or two? My ride can sit for 6-8 weeks and fire up within a second or two. Back in the day when all cars had a carburetor they did not have this evaporating gas thing going on. Something else at work here.

if i block the right carb it revs.
if i block the left it dies instantly.
what is this an indication of?

Right side of engine is running lean due to either vacuum leaks or carb/carb related issues with the emission-driveability systems.

I think you are referring to the throttle cancel switch for cruise control. Follow the wire back to the connector left side of frame and disconnect, then you have the extra reach you need.

Follow the + battery cable to starter relay A to the right of battery. Mounted to relay A is a 30A fuse holder, check the wiring there for bad connections and melting especially if your friend has added electrical devices to the machine.

The accelerator pump is manufactured temperature compensating, more shot when cold little to none when warm.

That pipe is used when CA emissions are installed and would direct fuel vapors back into the engine. Fuel leaking out of there means one or both carbs are flooding out due to float-float valve issues.

The accelerator pump is not the cause of the RPM jumping from 1k to 2k, pump only helps to prevent a hesitation when opening throttle. I would be looking at main jet, air jet controller problems etc. The engine is not advancing until the secondary mains start to open hence no fuel provided by mains ...

The 88-91 GW used a different coolant hose routing as you have found out with an incorrect right radiator. Bite the bullet and bring to a radiator repair shop to install a hose fitting for new radiator, you do not want to just disregard this coolant hose as it is the by-pass. Later years were water ...

First off it's NOT my bike but I have just seen this on another post and it scared the pants off me, apparently the guy was riding down the road and felt the steering a bit strange so started to brake and slow down, He never got to a stop because this happened!! Looking closely at the front you can...

Check your spark plugs and if they are old and carbon fouled that will cause a hard start condition. If unknown when they were last changed just go ahead and replace. A leaking float bowl gasket(s) will also require a long cranking time to refill bowls with gas to start. A properly tuned and running...

Before I did this I wanted to see which side was positive and negative, doesn’t really matter but I was curious so when I had the injectors out of the bike I turned the key on and tried to find the negative side of the plug by checking continuity from negative battery terminal to either side of the...

So you do have some spark when cranking and if fuel was present it should start. You can try a slight shot of starting fluid in the intake to see if it wants to start. I suspect a no fuel condition getting to the injectors, find the fuel pressure service port and depress the valve, if pump and regul...

Most likely the idle jets/circuits are still partially plugged or it has a vacuum leak(s). Does it also surge when holding throttle at 1200RPM?

After the belts are on and you have rotated the engine a couple turns, turn it a little more in the normal direction (CCW) until you feel the straight side of the belt get tight against valve spring tension then loosen and retighten the tensioner bolts. That should get the belt tension just right. ...

It is 99.9% of the time owner add ons that cause electrical issues other than the self inflicted.
