After having a few problems with a shockingly bad throttle were my 2020 ZE was just about impossible to ride in sport mode even with a Wiz flash, it's been cured. I was considering taking it to CJS for another ECU flash and rolling rode tune up.
I took it to my buddy Nathan Strefford at Streffords in Worcester who went over it with a fine tooth comb. If anyone has used them before you will know they are good old fashioned workshop and do a brilliant job on just about anything.
Nathan has a 2020 ZE himself which when he bought it, he insisted on doing the PDI himself and not letting a Yamaha dealer anywhere near it.
Anyway, he synched the throttle bodies perfectly (Yamaha dealers apparently don't do it too well) and took all the play out of the throttle.
He also found the rubber hose going into the evap was twisted and just about blocked and had probably been like this from new which would suggest the suppling dealer only gave it a cursory check over.
The result is one transformed S10 which now rides as it should. Very smooth and responsive on the throttle and smooth even around town on S mode and out on the open rode, she takes off really nicely.
I'm one very happy owner and happy to recommend Nathan for any work on your S10. Mine won't be going anywhere else that's for sure!!
