XT600E adjustable camshaft sprocket
 
Hi guys!

Do anyone know of any adjustable cam sprocket for the XT600 engine?
I looked an some known companys' catalogs but nothing:(

why adjustable? that should be strong part doubt the adjustable would last long...I'm supposing it's the camshaft your talking about....

I would like to "play" a little with my cam timing.
Why are you saying that it won't last...?
A lot of cars and bikes are using adjustable cam sprockets, without any problem...

I am guessing that as the XT600 uses a fundamentally de-tuned engine no-one has bothered producing an adjustable camshaft sprocket for it - all the ones I have come across have been in racing applications.

Just had a quick look and couldn't find any for a single apart from a crf450, a machine that gets raced a lot.....

I think the adjustable sprockets would apply more to engines with separate intake and exhaust cams so you can play with advance, and overlap. On a single cam you would pretty much be advancing or retding the cam timing.

You mean by moving the cam chain one teeth more than normal on the sprocket?

I'm searching for the adj. sprocket, because i'm going to install a stage 2 or 3 cam (280o duration, 10+mm lift) and i thought that it will be nice to have some 5o adjustment of the cam timing, for better results on the dyno.

I'm thinking less that one tooth, usually less than 5 degrees if I recall.

High-lift cams on an XT???

Please see my previous comments about turd polishing (Titanium springs on an XT thread)

I do as always have my tongue in my cheek and a grin on my face. Doesn't come across well in text form.....
