    Dim taillight Q?

    81 GS1100, has a new battery, 12.6V engine off, key off, good charging, SH775 V reg upgrade so the voltage supply is good, the issue is a dim taillight bulb. With the engine off, the 1157 bulb is only getting 6 to 7 volts at the plug in, the single element bulb is getting a little over 8 and is...

    81 GS1100 with 29 smoothbores.

    I got the new jets from Z1 ent. right after I found a nice box of them in my brothers tool box, I dropped the mains and pilots both 2 sizes and left the 1 size over air jets. It's a happy GS1100 now, the air fuel ratio never got fatter than 12-1. I wrote down the Greg Cope jet suggestions from...

    81 GS1100 with 29 smoothbores.

    I went to the storage unit and traded a Honda for the GS. The petcock stuck or the inline filter must have plugged, It was extremely lean so I just got it home. Later I tried it again and it ran fine, still too rich though. I pulled the carbs and checked the slow jets, I ordered the next...

    81 GS1100 with 29 smoothbores.

    I rode it today and got some mid range A/F numbers. It's still fat in the middle although a bit better with the 120 jets than the 125's. I'm going to pull the carbs and drop the needles a notch or two. While apart, I'll catalog the slide number, jet needle and pilot jet sizes. I went to the...

    Odometer repair?

    81 GS1100E, I've owned it for a few months and have been repairing things one at a time, the Odometer is re-set to zero and doesn't record miles, I fiddled with the reset button and had it working once but since I fueled up and re-set it again there it stays at 000. The gas gauge seems to work...

    81 GS1100 with 29 smoothbores.

    Today I rode with the wide band O2 sensor and again the A/F ratio was nearly 2 points different depending on if I was going into or with the wind. With the wind from the front-left it read 12.2 to 12.5-1 when I turned around and rode with the wind at my right rear the ratio got over 14-1. I can...

    81 GS1100 with 29 smoothbores.

    Well, this particular 1124 is a bored and stroked SOHC (750) Honda, the heads are primitive compared to even 10 year newer bikes. It's a nostalgia build.

    81 GS1100 with 29 smoothbores.

    Early on into this adventure I read that the stock carbs didn't play well with modifications. Not knowing for sure what's inside the motor but also seeing a Kerker header I assumed there was a reason the VM29 carbs are there. Now that I've seen the cams they appear stock. When I re-check the...

    81 GS1100 with 29 smoothbores.

    I've been searching but came up short, can anyone tell me how can I tell if these 29's have the 1.5 or 2.0 cutaways? Is the number external somewhere or do I need to remove a slide?

    1980 GS1100 (Square headlight) clutch never fully disengages

    Sometimes the kind of oil in it will make them stick, sitting will do it also, I used to tie the lever back on my KZ when it was parked. Riding it is a good way to get them going.

    81 GS1100 with 29 smoothbores.

    Selling the 29's and buying flat slides is my plan B. I don't know anything about the bike except the PO lost one like it in a divorce and bought this one as a replacement. The shop owner was pressured to sell it and wouldn't give the po any information, I expected to find a big bore kit or...

    81 GS1100 with 29 smoothbores.

    I'm still getting to know this bike, I put a wide band O2 gauge in it and have been monitoring the air/fuel ratios. I dropped the mains from 125 to 120 and it seems better. I may need to drop the pilots a size and check the needle position. I also ordered a new set of pod filters from APE, the...

    Polaris SH775 Opinions??

    I accidentally ordered a non-original one. I was sure it was genuine until it got here. Anyway, I got the triumph wiring harness and am proceeding with installing it. If it gives me trouble, my buddy has a real one for Polaris/Indian in stock. 1981 GS1100E

    Road trip with a trailer

    The guy I got it from had one for a drag bike but lost it in a divorce. Years later he saw this one and bought it just to make the point that he can have a gs1100 if he wants one. He didn't really ride it a lot.

    Here is the dragster at Joliet, my daughter drives and was pregnant last summer and had cylinder head cracks the season before so we haven't raced much the last couple seasons. The last time we raced full time we finished second in the Midwest Super comp Association. The purple Camaro owners are...

    New/Old GS owner

    I assumed it would take a thousand getting the 1100 going again, it's gone a little past that and did all the work myself. So far it has new BT46 tires an AGM battery, wheel bearings, regulator/rectifier, it has a short swingarm pivot bolt (earlier model?) and someone butchered the left aluminum...

    Goop hand cleaner on an old neglected seat

    Avon skin so soft bath oil will soften old seats quite well, I have a 69 honda cb750, the seat was so hard if I pushed on a square section the entire section moved. I was worried it would crack. Now that I've oiled it up a few times it is soft and pliable and it's been 10 years. It also helps...

    Road trip with a trailer

    Yes, 1981. The carbs are smoothbore Mikunis but I think they are 29's. I'm considering trading them in for 34 flat slides but I never get in too big of a hurry. I want to ride it a little more and get to know the bike.
