I need some help ...the other day went for a ride on my 1998 max and it started poping or kicking like in the drive terrain its almost like as if it were a chain driven bike that had teeth missing on the back sprocket....how it would skip then grab then skip then catch again an jumps to the point that the rider behind me said my back tire was kicking sideways but it only does it in 2nd gear 3rd an up its as normal....took tire off an no sign of any grindage or shavings of any sort in that area....so im assuming its tha shaft its self maybe?....i hope someone has some advice thanx in advance

Sounds like a bad 2nd gear. Case-splitting time!

If it was the driveshaft, it would do it in every gear.

Its definitely on the left side... at first it done a little in 1st an 2nd only under hard acceleration....but now its only 2nd gear an it does it at easy acceleration around 15-30 mph sometimes it dosent do it at all

With all the help and advice here on the forum and a good manual for torque specs its not a bad job if ya dont overthink it and scare yourself out of it. Not real technical just alota work. You'll save alot of money, so feed the monkey.

Plan on all the good up-grades. Get an undercut and overdrive gear set, O-ring and oil pump mod and DD clutch mod. Once you turn it back upright check your valve clearances, plumb for an external oil pressure gauge and Stg 7 crank case breather mod, then get some solid aluminum mounts for the install.

With the motor out of the way get #2and4 coils out of there, time for C.O.P.s a manual fan switch and an ignitech.

Sean can get you everything you'll need to git-er-done and you'll be damn glad you did it all at once with the motor out anyway for 2nd gear.
Makes for a good winter Project Vmax.

Not to just keep on with an old thread ....but its been 2 days sence ive rode an i got home from work yesterday evening an run the max dwn the road an every thing is as normal ....like i couldnt even make it do wat it was doin .....even under full acceleration like made a complete liar out of me .......think its still a second gear issue....or does that happen? Because i was puzzled that ive nvr had any signs of problems at all....an jus the other day me an a buddy went for a ride an after id say 2hrs into the ride we both accelerated an thats wen it first done it ....jus that suddenly

maybe it's worth draining the oil to see if anything nasty shows up, perhaps just by chance something got caught in the gears like a loose bolt, just a thought
Ill tell ya if you do have to split the case you'll see that there is no way anything can get into the "gear box" section of the case, just gears and shafts in there.
I would have thought that maybe you lost a pin out of that round gear selector deal outside by the clutch basket.
Things don't just fix themselves but if you aren't still experiencing the problem as first described Id call it good and keep it on the road.

Yea i have had the pins come out systematically until iv replaced every single one an it was because of the coke can gauge metal retainer bending and tearin loose.....however ive wonderd were the original pins went nver seen any of em except maybe one.....ive jus goin from 1st to 3rd......but was the 2nd gear recall even been a issue on the 1998?
