Hirsty Posted 17 hours ago Share Posted 17 hours ago I bought a Dragstar 1100 Trike which I've put a lot of time and money into but I get a massive tank slapper at low speed. Pulling away is fine if I'm getting up speed and slowing down is fine until I get below 15mph then I have to grip tight which stops the slapping. When cornering at any speed I get a kind of scraping, grinding sound. I'm mechanically minded engine and electrical wise but this has me beat. The seals on the forks are good, I've had the tyres off the rear end and checked, balanced up and re valved, they're new tyres. The front tyres not that old and in good shape. There's no play in the steering at all and everything is tight. Any ideas on what could be the cause please, as I said it's beaten me? Thanks........

Can you tell roughly where the noise is coming from? Particularly front or back? If it's back, I'd check the differential first then the drive shafts second. If it's front, I'd check the wheel bearings/spindle. As for the tank slapping, if the bike is still level (not raised or lowered at the back due to the conversion), all I can think of is check your front brake callipers, maybe one is playing up? I've split your two identical posts into separate ones... Quote Link to comment Share on other sites More sharing options...
