    New 01 GP1200R owner in Dallas Texas.

    Hello GreenHulk.net Members!

    I'm a newly registered member and this is my first post after deciding to register and get more good/helpful advice on my recent purchase of a 2001 GPR.

    I recently decided to roll the dice and pick up an 01 GP1200R I found locally that didn't start or run. I thought I was getting a deal IF the root cause of the issue was only the bendix (which I had), however - after pulling the stator cover off I was surprised with the sight of a broken crank snout..

    After much reading and searching about the issues on the GRP platform to include the broken cranks - I decided my best bet would be to pick up a good used (T&w) crank and a good used OEM flywheel for 430.00 shipped.

    I also ordered the crank seal kit and complete gasket kit from SBT. I should have the parts this week so I can being the R/R.

    My GRP has currently has the RIVA stage two kit installed on it. I'm looking forwarding to sharing this experience with you all and hopefully get this ski on the water in a few weeks. If you have any helpful tips or recommendations in regards to repairing this issue I would greatly appriciate it.

    TIA!

    Question

    welcome to the forum. I just bought an 01 GP1200R last month and I have learned a great deal since. I may be looking at a new crank. What made you decide to get the fly wheel also. Was something wrong with yours or are you just doing it to prevent having to do it later? Was 420 the price for both and where did you get them at? Thanks

    Hey - thanks for asking. I found a guy off of ebay (billythekid@aol.com) that parts ski's out and he had a good T&W crank candidate he was willing to selling me for 350.00 plus shipping that he claimed was just removed from a good running ski that he is parting out... I also needed a new flywheel, flywheel bolt (maybe) so he included all of the parts for 430.00 shipped. I decided to go with a new flywheel to eliminate an my original flywheel from the equation in the event it was the root cause of this failure.

    More details and questions about the 01 GP1200 R crank issue, fix options/solutions.

    Hey Everyone -

    A little more info (and questions) in regards to my recent searching, reading and calling crankworks about possible solutions for the GRP cranks and crank snout issue. CW informed me the best way to avoid the issue is as follows:


    "The only thing that we have heard that is supposed to work is taking the Flywheel off, cleaning and inspecting for damage… then re-torque the flywheel back on after every 10 hours or so…"

    In the event I break the crank again, I will consider sending one of the broken cranks to CW's and have them install/press on a new OEM crank snout as show on this page:

    http://216.37.204.203/yamaha_OEM/Yam...pe=13&A=84&B=5

    Anyone here had CW do this with success on thier GPR crank for around 400ish?

    I've also read a little on replacing the front bearing? CW mentioned they could also upgrade the crank to ceramic bearings.. I'll study up on that topic if/when I have to call CW again.. For now - I'm still awaiting my good used crank to arrive. Does anyone perform this flywheel check every 10 hrs or have you ever heard of this recommendation?


    Please advise and Much Thanks!
    Gary

    I have done a lot of reading in here and have not personally seen a suggestion like that. I would think it would be very troublesome to remove the flywheel every 10hrs.

    Welcome to the Hulk..

    As long as you lap the new/used crank to the flywheel and use red loc-tite on reassemble you should be fine.

    Thanks for the replies. I am planning to lap the crank and use red loc-tight on re-assembly. What is the recommended torque spec on the flywheel and what type of flywheel bolt is recommended considering I have no oil pump? From my searching - I read it is recommended to use a stud and nut vs. the OEM bolt? Anyone use or recommend anything other than the OEM flywheel bolt for increased reliability?

    And even then sometimes they still come loose for no good reason and have to be redone.....

    Torque for the OEM flywheel bolt is 53 foot pounds.
    I am also running premix, but retained the OEM bolt, can you please point me to the thread that suggested to use the stud and nut?
    I don`t think I would use red loctite on the bolt per say, the manual indicates 2 stroke oil...
    Thank You...PR...
