Gone.

I have an '86 V-Max that ran when I first bought it but became a parts bike for another V-Max I purchased. It has been sitting for some time and is mostly intact but the rear wheel area including the rear fender, rear wheel, shaft drive, and swing arm are disassembled. Also the carbs have been...

I love stuff like this. Thanks for sharing!

No yet. I'm going to send the carbs to DannyMax next month and let him clean them out. Probably a few gaskets need replacing also. I will update and let you know if that fixes the problem.

Carbs are seated all the way in. When installing them, do you use any kind of sealant or silicone? If the pilot fuel jets are blocked or clogged then the carbs would backfire on my 86 Max as well. Both sets of carbs run perfect on the 86 Max. They only backfire on the 2005 Max. I have...

Carb boots are brand new. I have two sets of carbs that I have put on the bike and it backfires through all 4 carbs on both sets. One set was recently rebuilt and runs great on my 86 max. I know that set of carbs is in good shape as it does not backfire at all on the 86 Max. I know the...

I have a 2005 Vmax with 15k miles on it. When I rev above 2500 rpm intermittent backfiring occurs thru all 4 carbs. If I let out the air/fuel mixture screw 6 times it will stop on all but one carb. I know that that is way too many turns and indicated an air leak somewhere. I have used two...

Thanks DMAN999! We'll put the Y back on the air box and see if that helps.

I'm no pro but the needles look stock. It does not appear that the carbs have been upgraded in any way over stock. What size main's do you recommend Sean? Do you recommend we put the Y back in the airbox or leave it off?

I dropped by Shane's house and took a look at his Max. The carbs were off a little bit but the bike is way short on power. He has a 4 into 2 Kerker exhaust plus a K&N filter with the Y removed from the airbox but I believe he has a stock carb setup. It idles great and runs smooth but has no...

Hey Shane, I called and left a message on Thursday but did not hear back from you. If you need any help I am available today.

I live near downtown Houston and have a Motion Pro synchronizer. I can help you sync your carbs.

Well, I took the bike out for a ride today and once again all 4 carbs are backfiring up thru the airbox. I'm beginning to believe that it's the recently installed Ignitech unit and COP's kit causing the problem. When I bought the bike a month ago it was bone stock and ran good. When I...

I was able to adjust three of the carbs so that they don't backfire anymore. I just kept adjusting the air/fuel screw out until they stopped. The fourth carb is still backfiring. The air/fuel screw on that carb is very hard to turn. What could be the cause of this? This could be the...

Carbs are backfiring thru the top into the airbox. They are all currently set at 2.5 turns out. How did you go about setting them to the right mixture? Should all 4 be set at the same number of turns or will each carb be set differently?
