    I wrapped all 3 on '97 GP1200 and have see that advise on here quite a few times. Maybe different engines have different methods of hooking up the tach?

    its all about using the correct wiring

    it is very hard to get a PET to read on a 65U... I usually put the wire on the plug boot side of #1

    what ever it takes to get it to work

    i have one on my gp1300r and it works at low rpms but starts playing up at high rpms and doesn't give a proper reading. I can use it to set my jetworks kit at 2500 and it works fine but out on the water at WOT you cant get a proper reading of what the engine is reving at. Don't know whats wrong with it, thinking it might be faulty

    I just found this thread guys trying to work out why my PET 2100 DXR tach is not working well. Im the same as the guy above. My tach is not reading properly. Most runs where Im at 7100 rpm is reads 2340 or some low number. 1 run out of about 6 gave me a true 7180 on my 07 GP1200. Same prob with my SXR 1200 most runs read real low RPM and wont go higher than 3000.1 time it gave me a true 7500. And I have it set to 23:46 correctly. anyone else had this issue and found a solution??. Tried it on cyl 1,2 and 3. Never on all 3 at once.
    It always gave accurate readings on my 2 stroke 2 cyl race engines, just not the 3 cyl
    ???
