    Very likely - is this bike new-to-you? maybe PO was cruel. I always suspect 2 nd gear problems on rocket sleds. Did you notice allojohn posts a few posts down?

      You should be able to pull the motor and roll it upside down and just pull the bottom case to remove transmission

        thanx for responding so promptly guys i just got done reading all johns posts and i dont think we have the same problem so heres a lil more info on my lilproblem

        when i try to power up thru 2nd gear i have full ingadgement of 2nd gear till about 5500 rpm and then some times it wants to jump into third and other times it stays in and il shift up to 3rd and then 3rd wants to jump down to 2nd gear under any power at all so i just granny shift in to 4th and 4th is good aswell as 5th so ive been looking at the parts fiche and trying to figure this out but now im afraid it time to turn wrenches so should i hit my parts bike up first to seehow everything looks before i tear into it or just pull the engine on my good bike???

          If you have a spare engine, I would recommend taking it apart first. I have done it on my GPz (upside down, split the cases, remove tranny) and I would practice first on the spare. You will want the tranny out of it anyway to put into your good bike.
