Good video, looking forward to seeing more work on the DRZ.
Unfortunately this was another persons bike, maybe i should buy a drz for myself though🤔
My guess is someone installed one of them after market timing chain adjusters , and had it to tight. Plus never changed the oil.
Actually what ended up being the issue is someone used cam caps from a different bike so the cams were being squeezed way too tight!
How did you prime the carb? My DRZ 400 S has On, Reserve & Off but no Prime. I changed my plug and pulled the carb off and checked the jets. Jets looked good so I put it back together (that carb is a b**ch! to get out!). Then the bike turned over. I know it wasn't the plug b/c I'd done that step separately. Anyhow thanks for the vid - after the bike fired up I was still able to get in a decent ride on Saturday.
This one had a vacuum operated petcock with on, reserve, and prime. Yours is probably a normal style petcock. You won't have the option or need to prime yours just turn it to on
I own 2005 drz400s, my bike was running fine, ive charged the battery and i put it back on and my bike started but turned off on its own, so i keep in trying to turn on bike and it started making clicking noise like that battery died?
Battery is probably toast you will need a new one unfortunately!
How many miles do you have and how long between valve check?
I've my drz since 9k miles, now at 21.5k and didn't check clearance ever. Which isn't good. Just got a new battery\spark plug and last fall I cleaned my carb. I bet I need to clean carb again since I didn't ride a lot. Anyhow, bike starts with a bit of push
un\jump into first and start. It rides fine, and after cold start it turns on no problem. Should I worry?
This one was at 40k i think valve checks are every 10k to 15k miles. Battery couldve died if not on a tender all winter. Does it turn over or just click? If it just clicks then probably electrical. If it turns over but is hard to start its something mechanical. Could be fueling but if the carb is clean and jetted correctly, i would check valves! Super easy and worth it to do
Where u trying to give it throttle at all while it was starting? And it still wouldn’t. Mine always needs a little throttle to start. Carb clean? Just don’t wana mess me engine up 9k miles
Carb clean is easy and couldnt hurt! I was trying to give throttle yes but it wouldn't start because the cams and head were destroyed haha
I would also recommend a jet kit, doing the 3x3 mod and getting a slip on if you can afford that becauee that really woke the bike up! Even better is finding an fcr39 mx carb and swapping that in, makes a massive difference in power and throttle response!

Damn bro, sorry 😢
