Reverse shift arm installation question

[abenadam]

It is not clear what should be position of shift drum lock arm during the assembly. Should it be '1' or '2' position (see the picture). If it is '2', how do I rotate 'partX'? Is it done by switching the gears? If yes, should it be neutral?

I already installed a rear case and locked the nut on the output shaft. If something need to be adjusted, can it be done without removing rear case?

Hope, someone knows the answer. Can't move forward with assembling the bike.

Part 'x' is attached to the shift drum. The shift drum rotates when the foot moves the shift lever, and the shift drum moves the shift forks to shift the gears of the transmission. The shift drum moves into 6 positions. 1st, n, 2, 3, 4, and 5. Part 'x' is a lock out collar for reverse. It keeps reverse from being engaged except in one position ... neutral. Neutral is when the notch is pointing up, and will then allows the lockout arm to lower, if the reverse switch is turned on.

Pix 1 shows a transmission that is in 1st gear. Pix 2 shows a transmission that is in 'N'. To rotate the shift drum, attach the foot shift linkage to the splined shift link on the left side of the engine. The link should be pointing upwards in the 12:15 position. To down shift, move your shift link forward, to up shift move the shift link rearward. As your trying to shift, rotate the output shaft so the transmission gears can line-up and shift.

If the bolt for the reverse lockout arm was removed, it needs reinstalled using med. lock tight. There is no internal adjustment for the reverse lock out arm, or any part of reverse within the engine itself. The only adjustment for reverse are the cables.

Once the rear case is on, I always reach in and grab the reverse idler gear and pull and push in/out. It should slide less than 1/8".

With the rear case installed, are you hearing a rattling noise when you spin the output shaft ???

Hi Greg,
Many thanks for the details. While working on assembling shifter shaft I figured that the only way to engage reverse gears will be if the arm will move up and remember I saw that it will be possible only if part'x' will be in position 2. Knowing, that reverse only can be engaged in neutral, I assumed that this part and shifter are related, but, dumn, for some stupid reason I didn't try to shift the gear.
Yesterday, I went to a garage to work on bike (before I saw your response) and just gave a try to shift a gear and, voila, I was able to validate that when it was in certain position, that I imagine was a neutral, I was able to rotate shift arm and validate that reverse gears engaged by rotating idle gear. So I've slightly oiled and attached the cables and that was it for the day.
And after that, I saw your response, that 100% confirmed my theory and practice lesson.
Idle gear slides about 1/8" and there is no noise when rotating the shaft.
Continue to keep the fingers crossed.

Thanks again.

What were you trying to fix ... why the engine pull ???

Glad you figured it out, didn’t see your post until today. Keeping my fingers crossed for you.

Oh you ... LOL ... just kidding

Have fun with the install. Before you bolt your engine up, and when it's hangin loose, be sure the jack under it is removed.
