I believe the culprit of the vacuum leak is the aftermarket carb boot. When I got home from work I took the carb off and checked the boot. I wanted to make sure I didn't put it on upside-down or ba...
Switched the pilot jet from 50 to 55. Only runs with choke pulled out. Tighten the boot until it won't tighten anymore. While running, sprayed carb cleaner at the boot, Rpm gets wonky. Stalled the ...
Pretty sure i was trying to tune with a vacuum leak at the boot. Took the carb off but didn't disconnect the throttle cables. Figured i would bring the air/fuel and idle screws back to their starti...
@TJ I haven't touched the bike all week and im about to go pull the carb again. So when I set the idle screw and the emulsion hole is barely visible under the butterfly (just like your video) I rea...
Really dont know what's wrong. When I have time I'll take the carb off and check if the diaphragm is seated properly. Might clean the carb again. If that doesn't work, I'll haul it over to my mecha...
With Allen heads, if I can get a hack saw onto the Allen head, without damaging anything else, I just saw a slit into it and use a flat head screwdriver. Using a larger Allen wrench has also worked...
I seem to be stuck now. Im making very small turns (⅛ to 1/16 turns) in and out on both the air/fuel and idle screws. Keeps jumping between slightly lean and slightly rich. Low to right idle ...
Finally got all 4 spark plugs pulled and cleaned. Bike fired right up! Still running a little rich. Turn the mix screw in a quarter turn at a time. White smoke is coming out. Must be lean now. Bike...
@TJ really?? Ok, I'll check those out. Ive cleaned 2 of the 4 spark plugs. Covered in soot. Been waiting on payday to buy a 6 inch extension to pull the other 2. Thanks for the advic...
I would buy a new mix screw. The bent one might work but personally I wouldn't bother with it. If nothing else on the carb is broken or cracked, I dont see why it wouldn't work. Also, if you use th...
Turned the air/fuel in to about 1 3/4, she starts and idles great. Apply throttle still good to go. If there's any black smoke coming out the exhaust its very hard to see. Turn bike off. Remove the...
8/30/26 Turned the air/fuel in to about 1 3/4, she starts and idles great. Apply throttle still good to go. If there's any black smoke coming out the exhaust its very hard to see. Turn bike off. R...
8/30/26 Turned the air/fuel screw IN to about 2 1/4 turns out and again to about 2 turns out. She's idling fine, quarter throttle sounds fine. At idle there is still a little black smoke coming ou...
@TJ I will never be sad about doing less work. They look awesome btw
When I have time (which I dont have much) I'm working on a similar problem with my vt750c2. You'll figure it out

8/23/26 My current ride is an 07 Spirit vt750c2. I picked her up last summer. Right now she has between 17k and 18k miles. I absolutely love riding this bike. Decided Im going to customize he...
Yep, thats what I did. Installed and rode around easy to make sure everything fit right. Good to go. Why do more work than necessary? Glad im not the only one.
In the video TJBC posted on Youtube years ago about installing risers, Tj drills out the stock bushings. Ok cool, easy enough. When I installed my new risers I found out they seated and bolted perf...
