Jim's 1985 GL1200I - The Diva hits the road, ride report

Last weekend the GL1200 took its maiden ride. The first ride was around the neighborhood to get up to operating temperature and then back home to do a leak check. There was a weep coming out of the radiator but I went out again anyway. On the second sortie I headed south on West Lake Sammamish Parkway and picked up I-90 east. I rode out to Preston on the interstate, turned around and came back. East of Issaquah the interstate limit is 70 and the wing saw about 4 miles of 80 MPH cruising. Total was about 20 miles. By then the weekend was over so I parked in the garage. The next day I discovered some spots of coolant under the bike. I put a catch pan under it and spent the next two days replacing a section of old fence.
The bike ran reasonably well for being off the road for 11 years. It is a little rough in the 3,500 to 4,500 RPM range. The linked foot brake was very spongy. The pedal would go down to the stop. This was different since it seemed like it had good pedal the day I bled the brakes. Today I started off by carefully inspecting the brake lines. Everything looked good so I went through the bleeding process again. I managed to get a fair amount of air out of both the front and rear lines. I found the pedal would pump up and after pumping it up and then opening the bleeder it would move a lot of fluid. It did wind up with a pretty tight pedal. The next thing was the coolant weep. It was wet at the engine side of the top hose. I used a hose from NAPA (who knows what car it fits) to cut out the upper and lower hose. I was able to manipulate the clamp around and it seemed to stop the leak. The only thing left was to go ride it.
Todayís sorties consisted of the same as last week, down West Lk Sammy to I-90. This time I went out to North Bend and returned. Everything seems to be OK. The brake pedal is firm and it has good effect on slowing the bike. Bike ran good with two exceptions. The clutch is engaging way out on the stroke, the lever is about an inch from fully released. The other problem seems to be carburation. It stumbles coming off of idle and is still rough between 3500 and 4500 RPM. This should be able to be tuned out. Iím thinking the clutch plates may be worn out.

The clutch engaging/disengaging when the lever is almost all the way out is normal.

Like Ken says, the clutch lever sounds normal.

The stumble off idle sounds like bent carb linkage. When you start to open the throttle the bike goes out of sync. You would have to remove the rack to test that because you need to watch the plates to see if they open at the same time and equal amounts.

Why ain't we ridin'?

Thanks for the replies. I'm happy to hear the clutch is normal. This is the first hydraulic clutch bike i've owned. It does feel a little awkward. About the carb linkage, there isn'T much to it. Just the two bars on the rear of the rack and the adjusters between the side carbs. All of that checked good when I had the rack apart. I did a bench sync and checked each butterfly to open together. All I have to sync the carbs is a set of vacuum gages. My brother has a old fashioned mercury manometer. I should check the carbs with that. If the linkage is bent, shouldn't it show on the vacuum gages when the throttle is cracked?

Mercury sticks may show more than a gauge. Hard to say.
If they looked good on the bench, then maybe you have something else going on.

Thanks, this confirms the linkage is not bent. I think the carbs need more sync work.

New problem, the radiator is definitely leaking. Coolant is coming out about 1/2 way up on the left side, about 1/2 inch from the edge. Looks like I'm in for a repair.

Simply not so. On my original carbs, the linkage on the #3 carb is bent enough to cause lots of trouble but impossible to see where, or how much, it is bent.

However, I know it's bent because I bent it myself trying to make room for a fix on the stripped threads for the sync adjustment screw.

Bench setting the synch may be ok,...but you should still adjust them with the bike warmed up,and running,with the manometer.
#4 is the base and they're all set to it.
You may find they aren't as close as you think.

Expect the unexpected. But don't expect the unexpected to be the unexpected you expected !

Dennis, can you point out what part of the linkage was bent? All there is the linkage from the center cable hook up to the throttle shaft. The throttle shafts are make from brass and they are pretty soft. I did take the butterflys off the shafts and removed the shafts. I will look for this.
I think the bike just needs more running and do a better job on the synchronizing. All I have are a set of vacuum gages. The needles jump all over the place. More to come.
