would a 14 tooth front sprocket on a drz400 cause premature wear on the chain guide or swingarm? i have been running 14/47

no. it's refered to as chordal action and the ratio would have to exeed 4-1 ratio. 47/14 is only 3.35.

I changed mine to 14/47 shortly after I rode with you at the Orca Run a couple of years ago and everything seems to be good. Probably got about 2000 km on it since then.

FWIW I put my (new 2 me) second set of wheels on - with 14/41 and deathwings. Runs great on the road - cruising at 110 (Indicated) with the engine hardly more than idling. Plus they went up my local singletrack and FSR hill test climb with no complaints. Must be my boosted riding skills from the MSF basic dirt bike course.

I just installed a 14 tooth on the front for a 14/44 combo. I seem to have a lot of chain slack though. Going on 2-1/2 years and 15000km. Does that seem like the time has come to replace the chain? Oh wait. I just found my answer in a Clymer manual. Apparently for 21 pins, the service measurement is 319mm. Mine is 321mm. I guess I'm shopping tomorrow. Hello Holeshot?

If you are trying to learn how to ride off road, you might think about 13 47 or even 12 47 , however you will be stuck at about 80 kms per hour on the pavement and change your gearing when going on an adventure ride.

Yes, I am trying to learn riding off road, but this is also my pavement bike. I've been advised to consider a 250 bike for playing around in the trails. Mainly so that I don't wreck my transportation for work. I have a long way to go to develop the clutch and throttle control, let alone the balance to ride confidently on sintle track. The Newbie ride was a great demonstration of that fact.

I went from a stock 12 tooth to a 14 tooth sprocket on my KLX450 in order to improve highway performance (less buzz at higher speeds). I have a Recluse clutch that kicks in at about 2200 rpm (idle speed for the KLX). With the new sprocket it is more hair-raising going down steep gnarly hills as I have to go faster to keep the clutch engaged. Next time I buy a bike with 6 gears!:)

Start with rides like this http://www.dualsportbc.com/forums/showthread.php?14162-Deroche-Nicomen-Nob and hone your skills and mods in a test mode with a little slower paced type of ride but still challenges available just not the whole ride. Sounds like some of the Squamish rides might fit the bill also for getting to the balance of bike and terrain, before you change your commuter bike into the bike of all evil;).

On the Drz a 14 tooth C/S is a nice compromise, low cost and chain length isn't altered...... works so-so at each end of the speed spectrum, on and off road. You will notice the loss of speed on the highway, but the Drz isn't a great high speed commuter anyway.
