Probably not, if so it would be minor changes but I could check.

so mines borked again, have yet ti get the official prognosis though so far its looking like its seized?  O.o!?

Picked it up after having had a full service, shims; cam chain; oil change etc etc. started fine and rode fine, there was a "once per rotation" clanking type sound at idle... after about 5km's it stuttered as tough it had run out of fuel, I was most of the way through the tank so I didn't think any thing of it. Pulled the bike over turned it off, switch the fuel tap to res, and start her up. Wouldn't start! sounded like the battery was dead.

So after having trailered it to Andy's work shop we started testing stuff (tx Andy) hooked a battery pack up and tried again, got it to start though it wouldn't run by itself, wouldn't idle etc. Checked the oil and it was all full and fine. Eventually we measure the battery which was fine.... took the spark plug out and tried to get the motor to turn over without the plug in without any luck. So far it seems like something has cause it to seize.

So my question is what could cause it to seize? something that didn't make any god awful noises, was missed during a full service, the bike has had two oil changes since I have owned it and has sown any metal fillings. Guess I should wait and see what Lecap finds when he pulls it apart, just getting restless I guess.

=\


What was the outcome? At the service did you have a new cam chain fitted?

They put the intake cam on the ex side..the cam lift etc is right and it works perfectly

Had a look at the cams and don't see the point. Lift is near identical (.15mm less on my sample :o ) but the intake cam is quite a bit narrower. The same effect can be achieved with a decent manifold & exhaust

Bit of a silly question perhaps, but on the "open road" what sort of average cruising speed are you guys running, and at what revs? and at that cruising speed, do you feel that there's a little more oompf if you need it?

so:
cruising speed: X at X000 revs
top speed: X
gearing: front/back
mods:

just curious, as this is the one thing putting me off the DRZ

Also have 15/44 gearing on the E,bike is happy travelling any distance at 120 km/h at the most!

think mines on 16/41 atm top end is like 160 thoguh apparently that big 16 cuase my oil leak so gonna change to a 15

The 16 eats the steel chain rail under the sprocket cover and shakes out the  sprocket cover bolts. The oil leak was caused by the thread stripped out of the countershaft sprocket nut.

If you tinker with anything on the DRZ get the jetting right. The DRZ seems to be prone to detonation when run only slightly lean resulting in hammered valves and jammed rings. Welcome to come and have a look :-\

I'm sure it's marked on the shock "+" for more/quicker "-" for less/slower

+ for more damping - for less damping, in other words  (lefty loosy, righty tighty)

Agreed there is not much of a lift increase, but the duration and overlap is different. The more the overlap, the hotter the cam.
With this set up you have 37 degrees more than stock, but this number is obviously made smaller by running different lobe centres.
