86 aspencade sei just bought and a issue

Postby wing86new1 » Thu Oct 17, 2013 7:57 am



Just picked up this bike last night, here is the issue. The previous owner used regular motor oil for all its life it has 68,000 miles on it . drove it home seems to shift ok but has a bad chatter feeling if you try to use the clutch as a engine brake, taking off seems to chatter also if you get on it hard. My question is if I change over to full synthetic motorcycle oil will the clutch plates clean themselves up or is this going to be a winter motor pull project. I see things about seafoam but just wanted to know if anyone has run into this issue

the other issue that I have is the dreaded charging circuit, I think it may be the regulator I could drive down the road for a hour with no battery issues 14.4v but when at a light it would start to fall in about 30 seconds to 12.2v then when I took off it would come back up, the owner tested the voltage coming from the stator while hooked to the regulator and said each leg was 6v not 4v, is the regulator back feeding the stator?

any opinions would help thanks

I have no idea where those numbers came from....I'll address your concerns tho.

14.4v but when at a light it would start to fall in about 30 seconds to 12.2v then when I took off it would come back up


The sei has a bit more power requirements than the interstate so the voltages may be just a little different than a non fuel injected bike....
The voltage you see can also be in error IF it is measured on the switched electrical system rather than directly on the battery....
By all means,borrow a good DVM and measure directly on the battery posts...
Measure ONLY after the bike has been run at 3k rpm for at least 5 minutes....Give the bike a little time to charge the battery after cranking...
My 84,right after starting,would charge at close to 15 amps (3k rpm) and fall back to 3 amp after 5 minutes.
Normally,a top running system will peak out at 14.4 volts and drop to 13.8-14.2 at a idle....
Be aware that at a idle,the stator is developing less power and the idle should be 1000 rpm + - 100 rpm....

It is possible that your meter is reading a bit low if it's tied to the switched ignition....
I did find on my 84,there was a 0.85 volt drop on the switched ignition...my meter would read 12.6 but the battery actually showed 13.45 at a idle...
unfortunately when the meter showed 14.3 volts at 3k rpm,the battery had 15.15 volts....


I had a problem....cured with soldering and a relay.....viewtopic.php?f=5&t=12522

That it charges is a good sign...you may be able to just clean connections to stabilize it....I do suggest,at least,soldering the "three yellow wires" and having the battery load tested....

Also....
taking off seems to chatter also if you get on it hard


Does it chatter after the clutch is fully engaged and in the 900-1500 rpm range..???
Some chattering can be caused by a unbalanced fuel system....One side is firing harder than the other....The engine should be synced much like the carbs bikes....On the sei...it's only left to right.There's no front to rear adjustment.

Here's a little reading bout this...viewtopic.php?f=4&t=494

Those voltages don't sound abnormal to me. The four-cylinder wings do not have the capacity to run the bike/lights AND charge the battery at idle, so the bike actually draws the battery down at idle - which is why you see the voltage sag. Once you come up off idle again, the stator generates enough power to run the bike and charge the battery once more, so the voltage comes back up as the battery charges.

As for the chattering, the fact that it's happening during acceleration as well as engine braking tells me you definitely have clutch problems - this is not the primary chain slap that can be caused by carb sync.

I'd do as you are suggesting - try a couple oil changes with quality motorcycle oil, and if that doesn't solve it, you're looking at replacing the clutch. However, this can be done with the engine in the frame, you don't have to pull the engine to replace the clutch disks.

did not know I could pull the clutch with no motor removal great news if there is no stator issues

well here we go I pulled off the front cowl pieces and what a mess wire nuts everywhere broken down smaller wires so will take a while to get rid of the gremlins. I think the electrical will clean up when I get rid of all these extras
