Very well done videos. Just waiting for your rear shock removal video. If you don’t have one, can you recommend one. I bought a used 2001 project bike and I want to remove the rear shock and take it to the shop for inspection. The bike bounces like a pogo stick right now.
Again, thank you an excellent job. I especially like the tool inventory and the torque specs (metric and english), very helpful.
Ill be doing a swingarm removal one soon which will get you right down to the shock too.
Great videos thanks for sharing your expertise.
Great job on the videos.
I have a 2006 DRZ 400s, can I assume the videos are accurate for that model also?
I’m not very good mechanic but I would feel confident doing the jobs you’ve shown, now that I actually have seen it done.
I’m a 200 pounder any suggestions for stiffening up the suspension, front and rear?
Yes, the 2002 and later S has the same suspension as the E and just about everything else is the same on the SM too.
I think you would need to change the springs in the front and rear suspension. I’m about 180lbs and the shock is about right at the limit.
Look for the spring rate calculator on the race tech website and you will see what spring you need on there.
Do you fancy doing one on adjusting/tuning and cleaning the carb?! cant seem to find any decent ones, I’ve used your others a lot and have found them invaluable. Cheers, Arran.
Hi Arran, sorry for the late reply. I knew I read this comment somewhere but couldn’t remember where.
I have done my carb but had to search on forums about doing it cause its my weak spot having never worked on them properly before. Probably couldn’t explain it good enough for a video
Hi just a little bit of advice please, ive recently bought a Suzuki drz 400e which I haven’t used yet but was advised to run the bike weekly to keep the battery charged, yesterday I left it on tickover for roughly half an hour and I noticed it started to overhea the water in the radiator overflow bottle was boiling like a kettle and water was all over the place. Is that a fault with the bike or my own stupidity? I know it hasn’t got a fan fitted.
Hi, Its not a good idea to let it run for that long without it moving as well to keep it cool. It is more than likely just because it was sat idling that it started to boil. It is still water mixed with other things after all and is still going to boil when it gets to a certain temperature. If your going to leave it sat for a while without using it I would recommend getting an optimate/trickle charger and just put it on charge over night once a month or something.
Hey, love the videos and tips. Wish I could take my bike to you, but other side of the pond unfortunately. My wifes DRZ400S has been having major problems, starts and idles for 10 min, than quits than it won’t run again for at least another 30 min, then it does the same thing. Petcock and Carb are completely ruled out, also it has spark.
He’s convinced it needs either the valves or rings done, as the crankcase is full of gasoline in the oil. Could this be something to do with the auto decompressor? Like if it was stuck open? I was sure this bike was holding idle just fine until recently. Not sure if there is something that could happen during a service that could mess things up.
excellent as always!
Thanks so much for the videos. Found them on YouTube, came here to quickly get the torque values. These truly are the best videos for working on a DRZ that I’ve found, couldn’t ask for anything else in them. Right level of detail. Thanks!
Could you include the tool sizes for the wheel bearing replacements? The front bearing in my 400S needs to be done, and I’d like to be able to order the tools and parts at the same time. -Tom
Sorry for slow reply. I’m sure the front was 20mm too
Great easy to follow video now fell confident to check valve clearance thanks
Thanks so much for these videos. I purchased a used KLX 400 that was “rode hard and put away wet” and have a laundry list of maintenance to do before riding season. This is exactly what I needed!
