My Uly has 1800 miles on it now. I did the 1000 mile service myself. The TPS still needs done but bike seems to throttle well. Everything is great so far but...

My trans sometimes shifts like a dream. But most of the time the shift into 3rd and 4th and rarely 5th can be a rather hard thing. The problem is that on a random basis going up thru the gears will be OK then I'll encounter a very reluctant gear. The lever moves fine, its that last movement of the lever that engages the next gear that will cause problems. By that I mean it gets hard to engage gear and I have to put extra force on toe to move into gear. There is no grinding or clunking. Clutch adjustment appears OK. It does seem to get worse as things warm up. On a cold bike it feels pretty good.

I should add that down shifts, going into first at a rest and finding nuetral are just fine.

I was thinking it would get better with break-in but has not. Anyone else having a less than easy shifter/gearbox?

Try moving the shift lever up 10mm.

I'm puzzled...what would moving the lever up do?

Check the primary chain adjustment; sounds like it could be a little tight (the chain gets tighter as the engine warms up). Having the primary out of adjustment will adversely affect shifting.

When I did the 1000mile check the primary chain did appear on the tighter side. On a cold engine it had less than 1/2" more like 3/8" free play/slack. I did not do any adjustment as this was within the range spec'ed in the service book.

Maybe I will back this off a little.

I vote for the primary chain adjustment... too tight can make it tough to shift... But I must say, the helical cut gears in the ULY make a world of difference in shift ease as compared to both my previous Buells (98 S3 and 03 XB9S)....

Moves the shifter in the arc segment. Try it, it's free; you can always move the shift lever back.

Now what I don't understand is how a tight primary chain can affect shifting. Someone care to elaborate?

A tight primary chain cocks the clutch basket just a little bit; but that's enough to cause the clutch plates to not disengage totally. Dragging clutch plates play hell with smooth shifting.

What Crusty said. If you could see that with the primary cover off, there is quite a bit of movement in the clutch basket when you put some pressure on the primary chain to check the slack.

When I looked at it I wondered how the heck there could be anything systematic in the adjustments. But doing the primary chain, clutch adjuster screw, then clutch lever freeplay adjustments in that sequence can work major magic on shifting, chain noise, and ride enjoyment.

The 3/4" play on the primary chain (measured as 3/8" while pushing up hard) is the only thing that varies from the specs in the service manual. It is a little bit more than called for but it works better.

What type of oil did you use when you did the service. I'm talking about transmission/primary oil. I find they shift the best with the proper Formula + oil that H-D sells. Did the problem start when you changed the trany fluid????

I've stayed with the Formula+. Bike always felt this way. It might be just a bit better since new though, perhaps with the passing miles it will improve. I have not checked my primary chain per the above suggestion yet.

I've noticed this reluctance to change up as well. Definitely when the bike is warmed up. I'd call it notchiness. Bike has done just over its 500 miles so I've put it down to still wearing in.
At the first service I will mention the primary chain adjustment.
