idle

Drill and tapped an extra drain plug i had for vm carbs and threaded a barb with teflon tape to make my fuel guage to make sure floats are at correct height on my vm carbs. My concerns are for when bike is running straight up vs on kickstand the reading i have (1st image) for left side carb...

Hello, I have an issue that I cannot find a solution to. My 1980 Special starts first kick, has a steady idle and rides fine for ~40 minutes. During the first 25 minutes the idle rises about 2k, which I adjust for with the idle screw while i'm at a stop light. Consistently, around the 40 minute...

Hey all been a while since i posted on here but ive been around reading old threads finding answers through other people problems for the most part. Now I got my own set of questions that I haven’t found in other threads. (Please link me to others if I overlooked them) Ive got a 73 motor Hughes...

Since sorting out a grounding issue and increasing the pilots (35) in my BS38s, the bike overall runs very well, but it doesn’t jump to high idle when choked. The choke seems to be enriching, but previously the idle would rise significantly. So now it requires me to coax it with throttle or...

hey guys. Thanks for all the help previously. Well...as it goes. You fix one problem only to discover more. Here’s my current set up. •Pamco with e-advance •PMA/Capacitor •uni pods •pandemonium ya mommas (planing on modifying them for mufflers) •78-79 bs38s with matching internals •jbm...

Hello everyone. I've made a couple posts on here but I'm stuck again! I have a 79 special with b38 carbs and I was having issues with the engine breaking up between 2k and 3k (pods and no baffles) which was solved by adjusting my needle level to give me a bit more fuel (already replaced MJ and...

i always wondered this... and I don't think I have a problem.... Why does bike idle high when cold with choke? I know other bikes do this, I was just trying to wrap my head around why adding more fuel causes this. 74 w/ VM-34's for the record

Hot dam well I'e been working on this beast for a while now I've done a bunch of stuff related to the carbs and leaks that I fixed. I cleaned carbs out once again then bought a chemical dip for them left em in there for about 15 hours took them out and they looked crispy also did this too all...

Hey everyone hope you guys had a nice Memorial Day weekend! Bike: I have an 79 xs650 bored out to the 707cc with a Boyer ignition system installed to give me the bare minimal wiring for a chopper style bike with a kick only setup. Issue: I do have spark. The only way I can get the bike to...

79 SF with PMA, Pamco. Im running all incandescent bulbs in my signals/running, brake/running, and headlight. Im wondering what I should be getting for voltage at idle around 1200 rpm. With no lights on i get 12.4v-13v. With all lights on I get down to 11v-11.5v. Essentially with the headlight...

I've been having on and off carb issues. I have pod filters and non-baffled straight pipe exhaust. Recently installed Hugh's hand build PMA. I have Bs38s and on my 1978. Main jet = 145. Pilot = 45, I changed both. Mixture screw is at 3 turns. At first, my bike would not idol correctly, it would...

Running kick only,wireing overhaul, small 3 A/h batt, pamco ignition, iridium plugs, Mikuni BS38 carbs, 130 pilot jet, 2 turns out on idle mix screw. NOTE: I have NOT swapped for nylon screws on my grounded brush yet. SYMPTOMS -Idles really rough at proper idle rpm sometimes the bike quits and...

So I have a 1975 XS650 with a pair of Mikuni round slide carbs. It was at the point where it would idle but die as soon as I give it gas (unless the choke was on). When this happens I can hear a noise come from the carbs. I now have it to where it will maybe cough a little with the choke off...

heres the story rebuilt engine, had air leak at carb holder, got fixed not 100% but better, took two hour ride (to get back to school), lost left cylinder half way thorough (believed to be because by air leak), ordered new holders from JBM, instaled carb holders, checked timing, also replaced...
