Welded on an angled bracket with two holes drilled in it and mounted it with the motor mount...

The finished product:

Wow, never thought my bike would be in the running for this! I'll have to accept and see how the voting goes!

rebuilt motor, cb500t, new elec ign, reg/rec, new xs coils wires caps, plugs, after riding for a few days, park it at night, then the next start, will only fire on one cyl, can change sides and see if that works, but no, the other side then fires, so the plugs themselves are dying, what would...

k after last nights short rides, never did a WOT yet, just checked the plugs today... one plug was no dirtier than when I installed it after cleaning it last night, and the other one just had a light coating of black on it, readjusted the air/fuel screw on that side and will repeat tonight...

Yeah I want this bike optimal for extended highway use (road trip!) lol. So with an 8ES, say, if it still fouls, would it be better to go back to the 145 jets and stay with the 8's or run a hotter plug (7) with the 150s (assuming a nice tan plug is acheived) giving more fuel?

Yes thats what I meant in the original post lol. went out tonight on her... marked improvement! The throttle position(1/8th roughly) at cruise speed/slow jet circuit where I had the problem is gone now! Bike revs smoothly and all the popping backfiring is gone... still a tiny flat spot now, but...

Carbs are spotless, took them apart again last night just to double check. Just idled down to 11-1200 and checked plugs, plugs were black but not as black as before, just a very very light dusting all over... cleaned them with steel wool and put them back in. Bike has a nice gentle idle at 1200...

Compresssion/timing are fine... motor was re-ringed upgraded to elec ign, having a problem with fouling plugs... just got back from a ride, checked timing before i left, spot on, screws were 1.5 turns out, screwed them in to 1 turn, off idle response improved just a wee bit, went to 1/2 turn...

Floats are fine. I am reading the entire plug, not just the tip, the entire plug is black with the 150s in it, just starting to get tan now... I think a hotter plug with the 150s should do it, with the 155s in it, the plugs look like they were dug out of a coal mine... I have 38s in it for idle...

K, have a CB500T that I just rebuilt, with open exhaust and velocity stacks, motor runs great, idles at 1200-1400, has a flat spot just off idle, then comes on like nobodys business! Carbs are all clean as a whistle new elec ign, etc. Now heres the WWYD situation: Carbs were 145 jets, upped them...

True, in my case a spring was strecthed, causing one cylinder to have more advance than the other before full advance.

Just a simple tip when tuning, timing, syncing carbs that many overlook when having problems like I was having, I had a lean plug on one bank, no idle screw response, bike ran well but had uneven power or a miss on one cylinder, before looking into tearing apart carbs, jetting, etc... there is...

Like the way that seat is going, any updates?

Re: Brat in the works CB500T - update: DONE!!!! :D Nice bike Greg! like that rear fender setup, its different! Well heres some finished photos of her after a few miles... still have to retorque the heads, shes a lil lean, so i ordered new jets today, other than that she runs like snot and...

Re: Brat in the works CB500T Havent fired her up yet, still in the midst of wiring, maybe driving tomorrow night! wheels are powdercoated a silver vein hammertone. I dont like the bars either but they have to do until i can get some more $ for a newer set. exhaust is up in the air still, dunno...

Re: Brat in the works CB500T Heres one with the carbs: still have to do the rest, was away the weekend.

Re: Brat in the works CB500T Well shes closer to done now! lol a Only thing holding me up now is to have someone else look at where i peened the cam chain myself just for peace of mind, and one of the lock nuts on the valve adjusters is stripped so i couldnt adjust the last valve. all thats...

Re: Brat in the works CB500T lol, i used a flat pan, cut down the original seat foam, then i used my old back seat out of my Duster and cut that up for the tuck and roll upholstery. Used rivets to attach it on the underside, can take a photo of the seat if you like

Re: Brat in the works CB500T not much new, got seat and coils done, waiting on rings still :P
