And you sold your Katoom and bought the DRZ for economic reasons? :pot:
Sorry to hear, why did it seize? Not enough oil?

Sorry to hear.

You have no choice, a seized bike is worthless.

Edit: Just read your post again, are you asking if you should take it back to 400cc? I'd guess a rebore to a bigger capacity would be cheaper.

From what I heard those DRZ's are very highly strung, so the motor's don't last very long.

Of course it's worth it.  Just think of it as a slightly more expensive DRZ.  And you should have confidence in the motor once it's done.  It's still a bloody nice bike.

Those thing are very sensitive for oil levels, if it is just a little low it blows up, I hve seen plenty.If you look after it ,it lasts forever.

DRZ dont last  :(

WISECO agents in Cape Town sells pistons sure you can have it rebored - relined and fit new piston and rod and bearings etc

Should not be to expensive (gonna be couple k either way)

If you hurt the cams, valves, gearbox, etc then your talking mega $$$ and then I would rather start looking for 2nd hand parts on ebay or some place

Sheesh man, that sucks. Do whatever is the cheapest, easiest and most reliable. Or sell it as is and cut your losses, and go buy back your 990. To date it's the most reliable bike you've owned ;)

agreed, to big though. I love the drz too

The thing that fucks me off the most is that I bought the bike as a 450/440 which is a full top end rebuildd while the 420 is just a bored out barel and a piston

What do you mean with 420?

440/450 is also just a bored barrel & piston...

Remember that the LTZ400 quad motor is the exact same motor as the DRZ...

I know that AdvMx has some 2nd hand parts for the LTZ, maybe find out if he has a barrel.

Then u can bore that to 440 and just get the 94mm piston

I think I am missing something here...

you are. The bike was sold as a drz450, 400 sm with a 450 kit on it, which turned out to be a 420 which is annoying.

Not sure if I will bother going bigger than 400, nice power but I need the bike to be solid and live longer than a few months

without getting tarred, feathered, drawn and quartered by the SSS - it seems like the DRZ's are not as reliable as I thought

 :peepwall:

N[]va - is there really a big difference in reliability between a 400 or a properly done 420 / 450? Especially since you're rebuilding the whole thing...

That bike is def not a 420

Like mine, it has a 2mm overbore cylinder and a 94.5mm Wiseco piston in it...

That gives you 439cc

Unless it was messed with after my mate sold it to the previous owner.

I will investigate further...

Remember it is not a laid back 650 single but a little higher strung. If it is properly looked after and oil checked religously (which takes only 1 minute of your day) then the motor is super reliable. 

According to all noteworthy sources a properly done 450+ will not suffer any reliability issues.

Guess so.

Fucks me off though as then it wasnt done properly before i got it. Bike had a wash/inspect once a week since I got it. Tire pressure twice a week, chain twice a week, two oil changes in under 2000 km's etc etc etc. I look after it.

As it is atm Going the 400 route will be faster and easier going the 440 kit will take longer and needs to have things imported.

Cost doesnt sounds like it will be to much of a diff on the 400 or the 440, cost and time aside sureley a 400 vs a 440 will be, assuming they are both looked after, more long lasting?
