Yes, mine is a definite keeper also. Only annoyance at present is a On Off feeling with the throttle at slower speeds, no issues under acceleration or cruising at higher speeds. I'm thinking possibly the TPS, I'm getting a bike mechanic experienced with the bikes to have a look, get it on a dyno.

Before you spend money on it adjust any slack out of the throttle cables. You want the absolute minimum without causing issues. Most people find that improves the issue you've got.

Balancing the throttles then setting the TPS is the second thing I'd try. Do it in that order or balancing them puts the TPS out as it uses No1 TB to measure the cable position which are linked to No3 TB.

If after all of that, and still twitchy, a dodgy TPS seems likely. Ive replaced the STPS on mine, done all the balancing and adjustment, it still is snatchy at low rpm, plus a hole in the response curve at about 4500-5500rpm.  Let us know how you get on.

Hi Mickey, great looking example of the mighty GSX1400.

Thanks for the suggestions My son, never one to follow written instructions  just adjusted the TPS in small increments without using a multimeter  and took it for a ride, he did that 4 times until the bike felt smoother ... seems he found the sweet spot as it was a nicer bike to ride home on, even at 100kph and backing off the throttle it was smooth ..

He knows a friend who is a bike mechanic who specialises in Fuel Injection road and race bikes, my son races Historic Class, Suzuki 1100, Kawasaki 600 & Honda 250. I will end up taking it there and having it put in the dyno and have everything checked to its optimum.



He also fitted a set of Oggy knobs to the bike to protect the engine cases.

Wish I'd seen your reply earlier  Oh well .. it appears to be a lot better. I've decided to have it put on the dyno and have it all checked properly

Micky, easiest tps check is on dash. Put it in dealer mode, theres a line that goes up or down as you adjust. Ive checked against multimeter readings, much easier.

Hmmm, what wizardry is this?  I've never heard of this method or displaying on the dash, care to expand on your post Grog?  Thx ole chap.

Do the jumper wire for error codes & there's a horizontal line on the side of the odometer display (I forget if it's left or right). Turn the TPS until the line is in the middle.

Exact correct Hooli👍
