Dunlop AMA slicks, gearing, and suspension questions...

So I'm planning on trying a set of sprint take offs on Saturday at BHF for the first time. What is the recommended cold/hot tire pressures for a 120/70 front and 195/70 rear for Dunlop slicks? Also, I usually run -1 front +2 rear gearing at BHF. What effect, if any, does the high profile rear have on the gearing? Should I go back to +0 on the rear? And lastly, should I adjust the shock ride height up or down to accomodate the high profile rear? Or leave the ride height alone? Right now it handles great with a 190/60 Dunlop 209.

Dunlops have been known to make bikes feel funny to my understanding, especially if they grow when they get hot. That is assuming the bike isn't set up for Dunlops.

I think the Dunlop vendor happens to be a CR for Nesba as well, if hes there with the Dunlop truck might not be a bad idea to ask him.

I wouldn't change what works wells.

If you want a change, I'll ride your bike, you ride mine, huge change right there.

NESBA - Seems to be missing, can someone direct me where to find it?

Nolan I would put the stock rear sprocket on. It is going to be a tight fit with the 195.

c.b.- I wanted to try them and my rear shock is easy to adjust.

dan- I've passed the question on to Drucker.

steve- good idea. I know someone who burnt a hole in the rear hugger with a 190/60.

Agree with steve.... you need more wheelbase to allow the slick
to clear the swingarm.

The front tire height should be close..... The rear will be taller.

Make a horizontal index mark on the tail directly above the axle.
Measure from the mark straight across the axle to the floor with
a YARDSTICK.

Change tire, measure again, correct for the difference.

Readjust chain slack when finished.

from a guy that went back and forth with 180 to a 190 to a 195 and back and forth.

this is what you need to do.

install the tire. lower your REAR RIDE height 5mm. make sure you at least have 1 1/2 inch from the tire to the front of the swing arm for safety measures for expansion "which you wont get shit from blackhawks" then if your bike is pretty twitchy before with the gear, it will mellow it out. don't like the way it feels? goes -1 more in the front, or 2 up on the rear. enjoy the new feel and grip!!!!


if you want call me with any questions. kim knows how to get a hold of me.

the 190 209 and 195 slick are almost identical in size, ive got both in the garage right now, less than 1mm difference so you shouldnt have to do much adjusting at all

oops didnt see he had a 190 there, lower the ride height 2mm then. took for granted and thought you were using a 180

One trick for you Nolan is to get your chain adjusters further back (get a longer threaded bolt) and you will need a longer chain. the bike works alot better with the longer wheel base. The wheel base is too short. This is from the higher ups and is a little secret so don't tell anyone ok. lol Seriously though if you need more info PM me.

Also depends on if it is an "n-tech" slick or not. The "N-tech" slicks dont grow like the old ones do, also the pressure is way different.. eg Non Ntech DOT was 30 or 31 in the rear, N tech is like 21 or 22 psi


If you have any questions call RTS (racetireservice.com) who is East coast Dunlop tire guy. They were more than willing to chat w/ me.
