    '96 engine into an '88?

    Greetings. Am in the process of replacing a lunched engine in an '88, with a '96 engine. (2 snapped conrods- not my work, but I reckon it was a nasty burnout..) Am I right in thinking that I could run the later ignition system if I can get a '90 on wiring harness, and a '90 on TCI or Dyna 3000...

    Loose swingarm bolts

    A quick note. My '85 had a 170/80 15 Mettzler rear, and a pronounced speed wobble at 110mph. When I changed the tyre yesterday, I went back to stock size, also noticing that although there was no side movement in the swingarm I could detect, the RH swingarm bolt was quite loose. So I torqued...

    R1 brake conversion question.

    I know most if this has been covered before, BUT Does anyone know the bore size of and R1 front master cylinder? I have a CB1100xx, but need to know if the bore size is ok.. And, on my 1985: If I use 2003 R1 calipers and rotors (rotors seem to fit), I know I need adaptors, but $160 + ...

    Faulty sidestand switch?

    Should I be concerned? If I put the Max in gear with the stand down, I lose the tacho and 2 of the four cylinders (it doesn't die anymore). Start switch is still isolated (won't turn over if ya stop it). :ummm::ummm:

    Time for the dyno and I have questions

    Greetings all. Talked to my dyno guy today, who worked for Yamaha when the Max was introduced. He has done only 3-4 Max's, usually they have been messed with (like mine). The last one had flatsides, which he ended up with 135hp at the rear (I wish) In order to make his work a little easier, I...

    misfire question?

    Greetings. I have an '85 Vmax, with a '96 engine, kerker 4-2-1 exhaust (I think), and Stage 7 kit with alloy tubes replacing the V-boost. It starts easy, runs smooth, pulls fantastically through the revs and gears. However, if I gun it hard, after it pulls like a freight train and I back it off...
