Having backfiring problems vaquero 2011
First I have tried everything I know, which is not much.
1. I installed cobra tri-oval slip ons. very loud on decel under 2000 rpm. 2. Installed powerpro Ad said it self adjust to all conditions Same backfiring better gas mileage very loud again but now under 2500 rpm. 3. Went round and round with cobra to no avail. 4. Installed powercomander V. Had great luck with dynojet on my 1600 nomad. Not many maps to choose from took the best from the list. Same as cobra except not as good performance and not as good gas mileage. 5.Took it to a performance shop. Dyno ect. more power mid range and top end. gas tank as you might guess now has a hole in it. Bang bang at 2500 I looked to see if people were running for cover. a little less below 2000. If they guy was not bald he would have been. Said you might want to add some air to it or that engine did not like the slip ons. 6. put hypercharger on. Made no difference. 7. Took slipons off stock map, stock pipes you can hear it but muffled. 8. talked to dealer they called kawasaki inherent they said in big twins. 9. sold slipons 2010 nomad 1700 no problems all stock now just slipons, Very frustrated what do I do now ? Love the style and the ride Login or Register to Remove Ads

Did you check for exhaust leaks?

I know this doesn't help, but I have noticed through the years that people having the most trouble with their bikes are the ones that have modified it. The more modifications done, the potential for more problems...
Is there something to that? I would think so... I hope you can get your problems solved... it is no fun when a bike isn't working as you expect.

I don't think that's quite accurate. The issues with the Vaquero/Voyager/1700's in general are there no matter if you mod the bike or not, the situation becomes once you mod it and remove the thin veneer Kawasaki painted on the surface you begin to discover what's under all that choked down muffled and baffled system and begin to realize the difficulty in correcting what MaKawi really left there. Options are to throw money and effort at it, keep it completely stock and live with what's there or trade it off... Not too impressed with MaKawi... Login or Register to Remove Ads |

I'm with Greg on this one, that is why I leave my bike mostly stock.

I don't understand the OP post 1 at all.. bald guys, holes in gas tanks??? HUH?
The more i read about the 17's the more I like my 16... But it sure is hard to know what the OP said in one post his first. All I can really tell is another one bit the dust, and bought a hyper charger thinking it was something more than just another big air filter box. The charger is in Hype! There are No impellers, and 2 flappers work better as a bra...... What the rest of the problem is i can't say. Sounds like a nasty bad air leak into a overly rich exhaust fuel mix. I consider my 16 pretty nice modified as I have it.

I think by "gas tank now has a hole in it", he means his gas mileage is in the crapper.

if you look with the engine OFF the flappers are wide open and out of the way. With the engine running there is vacuum that creates the flutter, for what purpose i can't imagine. As RPM goes up there is less engine vacuum so the flappers don't flutter so much but are still in the way of clean air flow. The hype is all you get besides a bigger air filter box. There is not a single impeller to pack so much as 1/10th BAR so there is 0 charge to it. All you get is current ambient air pressure and not on ounce more. Chargers all have some device to pack in more air. These are either gear or belt driven and in the case of a turbo exhaust driven. This is the way it is.

What I meant by the hole in the gas tank was the gas mileage dropped. I did check for air leaks in the exhaust. The bald guy well... if he were not that way already he would have been pulling his hair out trying to figure out what to do. He gave up add fuel take away fuel he did manage to get the most power out of it. Even though it is still a dog out of the hole. It should set me back in the seat but it does not. All I can think of is the timing may be off. Back in the carb days I knew more what to do. If it had no teeth I could make some dentures for it. Just looking for advice Guys... Any input is appreciated. I wondered if anyone had the same problem and what they did.

The timing is handled by the ECM and is not adjustable, it may be that your not used to the mushy soft clutch that Kawi installs, to prevent wheel lockup during downshifts. Replacing it with a better spring and Judges washers will make it feel much better on takeoff and downshift.
