well, I'm back from the depths of anxiety! Got my bike altogether and set it up with a Hughes PMA, electronic ignition, and a capacitor to make it a kick start. But unfortunately, the system worked well but my knee doesn't. So. I have to go back to a Battery and my question is, what all will I...

I have probably worn this subject out, but I am still looking for a miracle I guess. 5twins and a few others have been very helpful and many thanks. still having this one problem. I have a ,77 650D, following setup: BS38 carbs, pod filters, 1 1/2 inch open pipes reduced down with a set of...

I am at a loss. Been trying to get my old 77 running smooth and every time we think we’ve got it, something goes south! Awhile back, my alternator finally gave out and i thought now would be a good time to tear it down and get creative. Most of my work was cosmetic, but we did perform some mods...

This has probably been asked a thousand times but... i have a basic pamco unit, pma, and capacitor setup on a 77D. Question is, there seems to be a bit of side play in the advance rod. is this acceptable or is there a need for a shim? it isn't extreme but enough to make us wonder if the...

First off, thanks to those that have been helping me. Now, my continuing saga. I have a '77 XS that I've been slapping back together. Stuck a Hugh's PMA on it with a Pamco ignition. It has 1 1/2 inch open pipes(with torque cones) and no air boxes, just pods. Started out trying to pull off a 2...

Just a quick question. I ditched my plans to run a 2 into 1 with a mikuni vm 38. Now I am in the process of cleaning up a set of '76 BS 38's. since I'm going to run open 1 1/2+ inch pipes (with torque cones) and pod filters, I have changed up on the jets, all new ones in place, but need to check...

I have a ‘77 650 and i am running a 2 into 1 manifold sporting a 38mm round slide. I have outfitted it with a hugh’s pma and a pamco ignition. Thing cranks right up but i’m having trouble getting it to run smooth. Currently working through any pilot jet issues, following suggestions that if you...

Need some help. I have recently rebuilt my old 77 650D, and will now run a two into one carb setup. I am using a Mikuni 38mm round slide jetted as follows(from a previous recommendation). Main jet 330, Pilot jet 30, Needle jet Q2, Throttle valve 2.5, Jet needle 6DP1, and Air jet 0.5. I am...

i saw this bike on ebay where the guy had adapted a xs1 brake to a 16inch rim then mounted it on 35mm forks. wondered how he did this short of welding that little stud on the tube, then i came across a picture of this adaptor. looks like it was made for the job and was a yamaha part. can anybody...

I have a problem but I'll be damned if I can find it. Just recently my bike started acting up. I'll be riding along and it like the hand of god reaches down and unhooks the positive lead to the battery and my bikes just drops dead. I'll check for power and no lights come on. I'll let it sit for...

i have a 77D which up to now has been doing just fine, until the other day i cranked it up and as i'm tooling down the road sometimes upon decelerating to a stop, sometimes on the move, it just ups and dies. it's like your moving along and somebody unhooks your battery. kick it into neutral and...

i've had a little problem start up that i haven't had before. just out of the blue as i am driving along and come to a stop or decelerate the bike will just up and die because it loses electrical power. i know this because when i put the bike into neutral, the neutral light doesn't come on...

need some help here. i have a 77D. is my swingarm narrower than say on an '83 model. the 77 specs show a narrower rear tire than that on an '83. i want to mount a 130/90 16 on my bike but i wondered if my swingarm might be too narrow.

would someone be able to tell me the differences between the '77 disc and other discs? i understand there are some diminsional differences. i need some sizes so i don't mix them up.
