How long until tranny is damaged?
I am curious as to how long one can ride a hawk until the 1-2 gear shift problem begins to damage shift forks and second gear. I have 13,000 miles on my bike and the PO was a honda dealership owner so I doubt it was beat on. I try to shift as best I can in the "sweet spot" to avoid missing and grinding however it is inevitable a couple times a day. My last hawk had 48,000 miles and did the same thing so bad that I couldn't tell if it was shot. My question is has any one sustained real trany damage from this ridiculous problem?

Ive not heard of this. Im at 40+k and depending on what oil I use its always been a bit clunky shifting but never had a problem. Some oils cusion more than others. I have Amsoil in there now and its really clunky but its what I had on the shelf.. Motul seems to be the quietest shifting oil Ive tried.

10-40 or a mix of 10-40 (and not sure what the next weight up is) and 15-50 or 20-50 in the summer. I usually dont run straight 20-50, too heavy.
If you run Amsoil, use 20-50, its on the light side anyway.

Not sure why, but I've missed just as many 1-2 shifts at low rpm as at high rpm.
I did see someone mention that having pressure on the shifter before pulling the clutch in helps with that. I've not noticed a single missed shift when doing that, but I haven't been practicing for very long. It's definitely hard to keep a slight pressure on the shift arm while rolling on toward WOT, at least with a stock shock and a bumpy-ish road. Still.. something to practice.

One thing that helps, is,, The SH likes to be shifted with some athority, Not being harsh,and stabbing at the shifter,, But in the 1-2 shift,, you can not "glide" it in to gear.. seems when I get lazy, riding with the wife and such just putting around,,,,, it will crunch a bit in the 1-2 shift.. But if I'm paying attention to riding,, and shift like I mean it.. No issue, never grind, miss and much less clunk.I only have an hour or so with the transmission kit from Factory Pro, so not enough data there yet to say it is helping.. Though it "feels" better for sure.

How long until tranny is....
My Superhawk has 43,000 on it and I wasn't even aware there would ever be a potential problem with gears 1 &2. Mine's a daily rider in my commute where I go from 5MPH crawl lanesplitting to banging gears at 90 MPH onces traffic opens up. Weekends I go canyon carving in the east desert where this morning temps were going up to 100 degrees. When I bought the bike, the shifting was hard and the clutch fluid was black so I adjusted the clutch lever and then flushed the clutch fluid out two or three times per shop manual procedure until it was crystal clear; I used DOT 4 in the clutch. I also run 10W40 synthetic oil in engine. Thing shifts like butter.

When I use the clutch I miss 2nd about 35% of the time, but when I don't you it I never miss. My suggestion is srcew the clutch, I don't need no stink' in clutch. LOL

Ask 10 riders or 5 motorcycle technicians the question of does it hurt a modern motorcycle transmission to shift without the clutch, you'll get 12 answers from each group.

Yeah the motul is nice. I was running Honda oil and noticed a dramatic difference switching to motul. Castrol is also pretty silky.

I started miss shifting a few months ago, and it is now to the point where it will "pop" out of second to N (usually in a turn where I am counting on the torque to pull me back up), or once in a while, go from 1st and jam into N instead of 2nd, have to pull clutch in, go back to 1st, then up to 2nd and let out because I can't nudge it from N to 2nd....jams between the gears. I would say my forks are about shot, or my dogs are worn on 2nd. I don't thrash on it, but I don't baby it either....

yup you sure can, motorcycle transmissions are built to tighter tolerances than car transmissions. i've even banged out a few gears like this on a harley with no ill effects.
