unsmooth shift
Hey all
Pretty new to the site, and the hawk for that matter. I just got a deal from a dealor on an 02 SH. It has been sitting around in the showroom for two years without ever tasting any gas. I bought it with 1.5 miles on it out the door for 6k. Any way about my issue. When I was riding yesterday I would shift into 6th and the tranny would hesitate for a second and then go into gear. It felt like I was in neutral for a second and then brrrrr into gear?! This happened only when I was cruzing at about 4500rpm, and tried to shift into 6th. It happened a couple times. Wondering if this has anything to do with how long it sat in the showroom or not. It is still under warenty for like a year. I am about to get my 600 mile service done. Anything I should check out while I service???

Sorry man, classic 'Hawk problem...as in they all do it.
Moving the shifter arm one spline on its shaft helps some.
There's also some kind of mechanical improvement I've seen somewhere on this site. You'll have to do a search.
I try to put some upward pressure on the shifter on all my second gear shifts & that helps make them more precise.

Re: unsmooth shift
ok thanks
I do not mind if it is just something that happens to all of us. I was just making sure that I was not alone on this one.
Thanks again for the word
if anybody else has a fix idea, or whay it actually happens, let me know.

Re: unsmooth shift
Ya the clutch is fine. At least I never have any issues with it at any other time. I have put the 600 miles on in like two weeks and have had no problems until yesterday. It really is not that bad I just thought it strange.

Re: unsmooth shift
I am a new SuperHawk owner also and I would say the 1st to 2nd shift is one of the bikes issues. I have made the shifter adjustment described above and it helps. I also installed a new chain and it keep lubed and adjusted and that helped as well. Also shifting my SH @ 6000rpm on positive throttle almost alwasy results in a perfect shift. I have concluded that the only certain fix is to have the gears undercut (I have done this on other bikes and they went for knochy to perfect). The issue here is the work involved and the cost (Fast by Gast did my last trans and I think it was about $300 / I pulled the trans gears and sent them to their shop). JIM

Re: unsmooth shift
The two mods i did two or three years ago are the shifter spline adjustment and installing the Factoy Pro Shift Detent kit. It replaces the crappy non bearing shift dent arm with a nice heavy duty bearing dent arm and a stronger spring. This results in a nice positive shift eac and every time, especially 1st to 2nd. YOu have to pull the clutch and clutch basket to install the kit, but no internal tranny work.

Re: unsmooth shift
Interesting in that the first post was about a problem shifting into 6th gear and all the replies are about shifting into 2nd gear. There is a bit of a notch in most bikes between 1st and 2nd, but there shouldn't be anything like that between 5th and 6th.

Re: unsmooth shift
Hope I'm not jumping off topic here, but has anyone had any problems going from neutral to 1st? Every once in a while I'll be sitting at a stop light and when i get ready to go it won't drop into 1st gear. Rocking the bike helps a little but it still takes 10-15 stomps to get it to go down.

Are you at idle in neutral with the clutch in? If so, the trans input shaft has stopped rotating. The transmission relies on shaft rotation to get the drive dogs aligned. Let the clutch out momentarily, then pull it in and shift.
I generally do not sit stopped in neutral in traffic. I always watch my mirrors, in case I need to avoid being rearended. I hate riding in traffic!!

Re: unsmooth shift
ha ha .. I was wondering why everyone was replying about the 1st to 2nd gear miss when he was asking about 5th to 6th.
Not sure if anyone actually answered the question but I've never had or heard of a missed shift from 5th to 6th.

I've found that when I get near time for an oil change the missed fifth to sixth gear change happens to me. I change my oil about every three thousand miles.
Since the second to last oil change I've been using Honda GN4 20W50 and have not had the problem since.
How many miles since your last oil change when the missed shoft occured?

So, your transmission shifts fine except for 5th-6th, is this correct? Does it shift to 6th at all?
The only thing that comes to mind for me is a possible issue with the shift drum and or shift fork for 5th-6th gear. The trans has three shift forks. One for 1st-2nd, one for 2nd-3rd and one for 4th-5th. The shift drum has slots that guide the shift forks by its rotation. It may just be sharpness or a burred edge that will break in. If it is a persistant problem, there may not be any choice but to go in and investigate. You have to split the case to access the transmission for any service issues. I would probably mention it to the service department and then ride it for a while to see if it improves. Meanwhile, find out what you can about the service reputation of the dealer.

Re: unsmooth shift
Hey
Ya I only have like 600 miles on the bike. from what I have heard so far on here it sounds like it may just be a break in thing. It does not happen all the time just one ride actually. It usually does fine but once it went into gear and then felt like I was in neutral and then went into gear after I reved it up. Again it has not happend often. I think that I will get the initial 600 mile service and go from there.
Thanks

The 5 to 6 shift will be fixed by undercuting, Fast by Gast charges $25.00 a side so a six speed box would run $300. I am going to have 1st and second undercut which will cost about $100. If you do this you want to check the shift forks (make sur they are not bent) and shift drum for damage. I know this is not an easy fix but it will transform a gearbox. JIM
