NEW ZEALAND sr500 street tracker

I have modified your post for you so the pics show.

Don't take this the wrong way, but I am completely mystified why the pic/image thing baffles so many people lately. It IS an easy thing to use.

Please click on any forum category and open the announcement which has been posted at the top of every category on the forum in an attempt to help aid everyone in posting their pics.

p.s.: I absolutely love your bike and would really like to see more!

thanks Gman - i read - and re-read it a bunch of times and couldn't make it work.
i'm using safari on a mac - maybe it's a browser issue?
anyway - thanks for your kind help!

Hi Ken,

Nice machine!

SR

hello - and thanks for your comments .
here's a bit more info:

bike has tt500 alloy swingarm - YZ250 rear hub with YZ450 disc and yz250 caliper etc - about to change this for something better - have picked up GSXR1000 k5 caliper and master cylinder..
was also thinking of putting a 4 pot on the rear! - it has a rearward weight bias - anyone had this idea before?
trying to find a better front disc to start a front brake upgrade too -the YZ MX stuff is pathetic.
looking at Vanem's nissin 6 pot and master cylinder.

i am using 19" front and 17" rear and the avon distanzas in the softer compound.

bike has pro taper bars too -and DRZ400 SM mirrors that are very good.
i use buell indicators as they are cheap and good looking.

the 540 motor i have is from a racebike - has very nice ported head - but the previous owner swapped the cam back to a std one.
can anyone recommend a good midrange cam for a 540 with a new Keihin FCR 41 from sudco?

also - the new carb only has a velocity stack - is there somewhere i can get a K+N that will bolt on the the FCR?

i'm going to swap the motor last - i'd like to get the braking and chassis sorted. i think i need a couple of extra inches rear ride hight - i would like to get some ride height adjusters installed on the ohlins - i think the tt500 swing arm has different shock mounting distances from the sr500 arm and is making the rear too low....

of course the bike is so far away from std - no-one can give me geometry advice...

any thoughts?

Choice bro

looks bloody excellent
How do you like the Avon's? Been contemplating them for my scrambler

I had a opposed piston caliper on my old chassis and it was WAY overkill. I changed it to a single piston caliper and it STILL is plenty. Too much chatter at the rear when riding hard. It will want to lock up.





I knew I had posted my bikes chassis dimensions somewhere. Took a bit to find but, heres the meat of the post.

These numbers are off my TT framed SR500 and were simple achieved by the use of a longer swingarm and taller rear shocks (or shock in my case).
Fork offset---1.380" (35mm)
Rake-----------25.5 degrees
Wheelbase---56" (142.24cm)
Trail------------4.5" (114mm)

17" wheels front and back
Fork length is .5" (12mm) longer that stock SR forks.

These numbers are similar to most any current 600 crotch rocket and were measured with zero suspension sag.

By "no sag" I mean that the suspension is topped out. Not even bike weight on it. Really the only true way to compare. It gives a common point for all bikes to be measured from. Overall bike weight, front/rear weight ratio, rider weight, suspension settings are all variables that are to difficult to control and all will effect the wheelbase, rake, and trail.
