Justin are you talking about the two hooks that are mounted on the seat to hook onto the frame lock? If I have a spare its yours. I will get back to you today.

Yes those two hooks. That would be great if you had extra. I know it's going to hold me up sooner or later ha! In other news I ran wiring and have power. Although I did not route the harness so I have to take it all apart. Blinkers did not work either. New flasher from Honda. I don't think I hooked it up right. It's not just if and play ha

ok so now I have one side of the winkers working but not the other. I posted in the sohc4 bikes section. new everything wiring related. the flasher works with the L/R one way but it just buzzes the other way. if I switch the blue and orange coming out of the left hand switch then the other side blinks, so it is not the switch, which is also new. the old flasher behaves the same. I seem to have all the stuff connected properly according to oldmanhonda diagram for a K1, the only thing left is to get hard connections for all 4 winker grounds....but when I switch the orange and blue, the other side DOES wink indicating the makeshift grounds I have ARE working. i am stumped

thanks Stev-o! I took the lowering blocks off and it made almost no difference. I can still only stop with one leg off to the side with a stockish seat. cant really even tiptoe walk the bike though. oh well.

Ha!  The day after I bought my 750 back in 1980, I was in a school bus accident that left my right foot non weight bearing for about four months.  I spent the entire summer after my senior year riding the bike with crutches strapped to the bike.  Only once did I stop with the bike leaning to the right side.....I did not do that again :-).   I guess what I am trying to say, is that it can be done and I'm thinking that you won't have much of a problem with the bike being too tall.

Everything is looking great, by the way!

In relation to the lights. Are the front on one side flickering or is the entire side functioning?

tews, the whole side (front and back) are flickering properly. then when I switch the orange and blue from the switch itself, I can make the right side flicker but not the left. either way one side can flicker and the other side nothing except the flasher buzzing. I murdered my battery last night so I threw a fresh one on and same problem, can eliminate that. I do not have my points plus or coils plugged in but that is a separate circuit. maybe if someone could unplug their points and coils from the harness and try to see if they are getting what I am getting?

My signals used to only flash on one side and would just come on solid on the other side. I never did figure out what was wrong with it.

I was hoping if I replaced the harness and flasher that I wouldn't run into this problem again but sounds like I might! I'll be watching this for possible solutions.

The k1 did not come with the buzzer. That may be the issue. Unplug the buzzer.

no no, not an actual signal buzzer. the flasher RELAY is buzzing. it is a new honda oem superseded part for the original flasher relay. when I plug the old relay in it does not buzz but it clicks steadily

Is it the flasher buzzing or the buzzer that indicates the winkers are winking? If its the flasher maybe its gone bad. I had  a similar problem with my K1 but found the po had cut some wires. Repaired and they work fine. Hope you can find a solution......Gary

Woops you answered before I posted........

Remove the flasher once. If you have time and the 7 bucks buy a universal flasher at an auto store. Should have 3 prongs only. I think the number was p39 or something.

I just went over the original harness and the new one is actually identical in every way. I dont have time to get to the store before I work today, I I get off after they close, but I will check tomorrow morning about that flasher. my flasher has two prongs, just like the original. I am hoping that will do it!

in other news tomorrow thru sunday I am taking my motorcycle safety course! I am nervous and excited. normally you have to sign up weeks in advance but yesterday I looked and there were two spots open for this week! the stars aligned and I can able to get off work. very excited

I'm going to be trying a 3 prong flaher from NAPA ... an EP36 if I remember correctly. Though, I don't know if you guys have NAPA in the US?

Anyway, from what I've read the 3rd prongs helps to get an even flash rate on both sides if the loads are slightly different. Sorry I can't be of more help but I may be in the same boat this weekend.

Yep IW. That's the number. There is a green ground wire that hooks up to it. Honda has the wire stuffed behind just have to find it. I had it on my 550. Worked great.

New relay bought! Love having a napa 5 minutes from the house. Will check it out when I get home tonight. $16 I hope it works

The new flasher has a + a - and an L. I have a grey and black wire, and then a spare green wire with the proper blade connector. His green wire was not used before. Is it used now, how does this flasher hook up. I don't want to fry the flasher. I have plenty of fuses though ;)

I know the green wire is not used on US bikes it is a ground wire that was used on bikes for the UK. I dont know where it would plug though, maybe on the one that has the minus, find your hot wire ( maybe black). the the gray would go ont the L shape. Make sure that black is hot............Gary

I don't remember off hand. I had to plug and play. I didn't fry it and tried the combinations until it worked.

You may want to recheck your wiring.  I remember having a similar issue and it turned out I had plugged a light blue wire in to a blue.  (or was it light blue in to grey??) I cant really remember now which it was, but it is an easy mistake to make.

The L is load side meaning the wire that heads to the lights. The - will be the ground side so the extra green. The + is your power source so whatever color that one is ... black?

Check your diagram to find which wire is load side (lights) and which is source side (battery).

alright, so the new flasher did not solve the problem. it just blew 3 fuses. the K1 only has a single main fuse too. I have isolated the different components and taking the switch out of the equation does not fix it. so my switch is ok. I even isolated the wires going TO the relay. I ran bypass wires outside of the harness, both gray an black, to their respective destinations and the same result occured.

There really is no difference in the circuit until after the switch. Grey gets switched between the orange and light blue. So one side is working check for a short after the switch. It could be a bulb or bulb socket on the side not working. The grey supply's both sides so trace after the switch. A 12v tester comes in handy. Just a bulb and wire. Disconnect it in the headlamp and remove the front or back blinker to isolate one from the other. Test separately

GOT IT! after various testing of jumper cables outside the harness to eliminate any foul play inside, things were the same. I started rearranging the orange and blue cables and different winkers and I could get all the winkers to fire except the rear right. this was obviously the culprit. hooked up my old winker to it and it worked. I figured the new winker was shorting (hoping it was not inside the winker). started unbolting the bracket and BOOM i put the wire too close to the bracket bolt and it broke the wire sheath and shorted. I am now working on fixing this and wiring up permanent ground wires for all winkers. then I am unplugging the electrical and routing the harness properly, then plugging up again and that should be DONE! thanks for all the help. that new 3 pronged relay did not work for me on my K1, but it might work for someone else

ok after checking the new relay i just bought with the CORRECT wiring.... :-[ I see that it does work. gray to L, black to + and that extra green to -

it just blinks REALLY fast. so now I have options :)
