1981 GL1100I fireing order

Postby Bill Powell » Mon Jun 27, 2011 1:12 pm



Hello,

I'm looking for some help. I just inherited this GW from a friend of mine. After re-building the carbs, replacing the battery and starter relay the bike started up yesterday for the first time in three years. The idle is rough but steady at 1500 rpm's. My worry is this large knocking noise. When I crank back on the throttle and give the engine more RPM's the knocking slowly goes away. Only at 1500 rpms and below does the knocking noise come back. Valve Adjustment???

Also, what is the correct firing order for the cylinders??? Routing spark plug wires and it doesn’t seem to make any sense to me coming from the coils. I need to make sure that I don’t have a spark plug wire crossed or out of sequence.

Thanks
New Winger

This helps and thanks alot WingAdmin. Your How-To Articles have helped me get this thing running so far. Hope to be riding within a few weeks.

Hey, one more question.
After running the motor for several minutes yesterday. The cooling system seems to be operating fine. The temp range stays at the mid range level the entire time. Every now and then the fan motor will kick in and it stays on for around two minutes and then shuts off.

After around 30 minutes of running, I noticed a small sign of coolant on my gargae floor. There appears to be a drop of coolant every 20 seconds or so coming from the weep hole. My questions is, can the water pump seals go bad without the pump going bad?? This bike hasn't been started in over three years. The motor has 27,000 miles on it. If I change all of the water pump seals, how can I check to see if the pump is bad??

Thanks
Bill

Of course this is not outside the realm of possibility, but it's not anything I've ever heard of - a lot of these bikes have their original water pumps in them, and if the seals are just going to "go", they likely would have done so sometime in the last 30 years. There's no movement in there, the seals are pretty well stuck in place.

What causes the seals to fail is when the bearings in the pump go. This causes movement, which disturbs these long-hardened seals, and causes a leak.

You can replace the seals...but chances are it will just start leaking again in short order. It's a fair bit of work to get TO the seals, and involves removing the pump. While you have it out, being that it's likely the cause of the problem - you might was well replace it.

Sorry, not the news you were hoping for, I'm sure. :)

Well if it has to be done, I'd rather do it while everything is apart. No sense in doing it twice. I guess I have to be extra nice to the better half for a bigger allowance this week. :lol:

Thanks for all of your help. I still have a ton of work to do on this bike.

Bill
