Are you worried about losing top end???? If not go to ebay and punch in this number in the search.....190368299531....for like 10-11 bucks shipped to you..you get 2-1mm shims and 1-.5 shim....you can shim from .5 all the way up to 2mm (max) with this kit...I just did this for now and u will definitely tell a difference....I am prepping to send the sheaves off to mike to get work done so the shims will come out..but for a cheap fix...thrill these REALLY work!!... now I am getting ready to put an orange or purple spring on my secondary on the fence...but I think I am going orange...i run stock tires...so orange should be enuff...something else you might consider doing and they are like 25.00 from EPI....next and I am getting ready to do this also...Wet clutch springs...I am putting stronger springs in my wet clutch so that it revs approx...500 more rpms before she really bites...this is supposed to be the big kick...kinda like dumping the clutch type feeling....i have been told WHEELLIE city with all of this work done...so cheap way...shims 11.00 spring 25.00 and if you want to add wet clutch springs approx 60.00 they also have 1000 rpm stall but I think that is too much for what I want....now as far as roller weights I just got some lighter weights for mine I believe stock 660 is 18Gr my new ones are supposed to be 16GR I just bought a little gram scale to weigh these out and make sure they are proper...I have heard of guys going down to 14GR and also doing combos..BUT.. if you mix them they have to be set across from each other so to maintain balance.....Hope I have helped.....

He said he has a grunt kit installed so that means he has 1.5mm in shims with lighter weights already.
He says he wants to bring the front end up easier. You need to add enough shim to make it 2mm. You need 500rpm wet clutch springs from Hauck.

Hit the clutch kit thread in my sig to see where and how to get these two items.
As far as the wheelie there is NOTHING more you could do to get them than this in the clutching.
Search on here for my carb slide spring mod and do that also.
Make sure you post back up in this thread someday to tell us how it all worked for you.

You can get the 500rpm wet clutch springs and a secondary spring from hauck like wun said for $60.00 , but I don't see anything on how many lbs the secondary spring is.

Um.... Grunt comes with only a 1mm shim, not 1.5 and 4 lighter 16ish gram weights. So if you're going to go shim wise stick another .5mm to it, and like me and whole bunch of other people, go Greaseless.

Buy 2 .5mm shims and try a full 2mm first, it's 25% better than using 1.5mm and a VERY noticable difference.
