RPM's jump above 6.5k...

[Shuriken]

Noticed that the RPMs jump quickly to redline when I get on the bike hard and get around 6k.

Clutch slip? I haven't noticed it otherwise.

Something's gotta give. Either its the clutch or the rear tire or you are stretching your arms!

Mine was slipping little while ago.
Had taken it out, cleaned, adjusted etc. and still slipped.

Read TC's extra plate fix and tried that and it has been working well since.

Must be clutch. New rear tire that I doubt would slip in top gear. I should polish the clutch cover while I'm poking around in there.

Not terrible slip. May wait a bit to get to it.

Hey there Ben! You gonna pedal that XS towards Green River one of these days? Went to Salt Lake this past weekend,, rode over to Dark Horse's home and met for the first time(he and wife are super nice folks) went on a ride and came home Sun. without so much as a hiccup fron the ole' Venturer.

sounds like a clutch slip

could be 2 things clutch needs replaced or adjusted
or maybe the oil your using could cause a clutch slip but if it is only happing in top gear i would so it is the clutch going bad and not the oil

so what kind of oil do you use

[Shuriken]

Yeah, I agree.

I use what's on the shelf, non-synthetic only. Pennzoil probably.

I have only noticed it in top gear.

well the only thing i can say do a high speed test run where you start in first and start banging the gears at redline and see if the problem happens in all the gears or just the top gear i mean that how i can tell my clutch is slipping and needs adjusted or replaced and i need to change my oil i like thew moble one synthatic is also messing with my clutch

and does it only do it in top gear or all gears above 6 grand

Ben,
It shows up in top gear, above 6K because yu are putting the most strain on the clutch. I would suspect the springs are worn out. I replaced mine January, and the old springs were about 3/8" shorter than the new ones. this was the short clutch springs!
I measured my fiber plates, and they were almost new, so I just put in the springs. the clutch has not slipped since, and I was slipping in both 4th and 5th.

Seems like just top gear above 6.5. Springs would be a good thing to try.

I need to find out where and how much clutch parts are... and what to avoid.

Heavy duty clutch springs can be had from most motorcycle supply houses. I think even JCW might carry them. I know partsnmore does, as that's where mine came from. The down side to them is a $35.00 order for free shipping. If you order a few needed items, oil filter or two, etc., you should be there quickly.

Noticed it again today - exact same spot, in 4th gear riding 2-up.
