Smile power problems (clutch?)

new here so hi to all
hows everbody doin?

ok first off
i am from london but have been living in holland (haarlem) for the past 25-26years, yep long time i would say,
after 12 years of no bike my heart was set on an vtr sp1 or as you guys know it the rc51.
now i had some problems with this bike here and there and never enough cash to solve them.
bike has been running fairly good apart from no power commander cause them things are not cheap!!
i did a test run on the dyne and saw a massive dip!!
ok thats the flapper mod, so did that, rip the bloody thing out as shown in the rc51org mods page (handy site btw)

ok this was with superpole exhaust.
that seemed to not work wel in low rpm,
now i have some high mount leo vince on and seems much better;-)
now i noticed more in the bottom so was much much easier to pull nice wheelies in first gear with a bit of clutch.

ok last few days i have noticed that wheelies are really hard to do?!? i can barely get the front wheel of the floor,

seems to drive fairly ok but have a feeling the clutch plates are (glazed)
anybody have any experience with this?

i want to swap them out for a barnett race clutch kit,
any info or tips would be welcome guys.

thanks

The Barnett Kevlar Clutch Kits work very well in the RC51 especially the SP1 Clutch which had some issues later ironed out in the SP2 version.

The only down side is they are a little grabby when launching hard and they dirty up the oil VERY quickly.

The Barnett clutch is a better unit than the SP1 OEM clutch setup

The SP2 clutch is a better unit than the SP1 OEM clutch setup

For street use only I think the SP2 clutch is just fine. For race purposes the Barnett does a better job with launches.

Hope that clarifies things a bit.

The SP1 clutch would audibly shriek and slip on hard launches and suffered accelerated wear during the same.
