Help with Kuryakyn Hypercharger
I'm hoping anyone out there may be able to point me in the right direction. Last year i bought a 2001 Dyna Lowrider with Stage one and Vance & Hines straight shots. This year i added a Kuryakyn Pro Hypercharger. Today i took it out for a test ride and it's really hesitating when i give it throttle. It seems to lag a lot and never seems to respond when i crank on it. Is this just a simple carb adjustment or major tuning???
Thanks for your help.

RE: Help with Kuryakyn Hypercharger
I had this same problem on a single carbed metric bike I used to have. I went through all the basic troubleshooting steps and finaly found it had a very small tear in the vacuum diaphram on the throttle valve. Would seriously bog down when any abrubt throttle was applied, but when I gradualy rolled on the throttle it would somewhat respond. I changed out the throttle valve and it ran like a scalded dog again.
take the 4 bolts out of the top of the carb and the throttlevalve will pull staright out. It has a large rubber diaphram bonded to an aluminum slider valve with a longjet rod going through the center. It's an easy fix if that is it. I'm thinking it cost around 120.00.
The carb on the metric was almost identical to that on most Harly's I,ve worked on.
Hope this help

Loose the Hypercharger gain back the HP you lost when you installed it then check the vacuum cap on the carb if it still doesnt run right, its either cracked or missing.

Could be dead wrong but I thought I read some where that it was suggested that the pro series be used with a stage II kit or with some other performance upgrades. I'm not one who knows alot about the workings of the engine, I just like twisting the throttle.
