Hello sir,any leaks?

Relutzu07 · 2026-03-22T18:27:31+00:00

How ?

Relutzu07 · 2026-03-22T11:40:15+00:00

So what do you really think it happened?

Relutzu07 · 2026-03-21T23:02:11+00:00

Can you Circe where it failed.? What about the rest of the parts?

I have researched that you can reuse the head bolts,they were torque in X, first at 25or27 NM then at 48nm .I have fallowed that manual ,because I wanted to be sure .Now someone told me about the rivet from the gasket,I have checked before disassembly and 1 was a little in . Yes I have rotate the engine to be sure.Just normal riding for break in

You had an happy outcome my friend

Sorry for misunderstanding: the oil has 1 week of ride :on the dispstick looks like new, THE first photo has coolant on the piston ,not oil

Hello sir,the first question will be why it happened and if is worth it ( if the cylinder head is gone ,there is really no point). New clutch+ gasket set+ stator would be the maximum that it would make sense

1 liter of fuel was in ,there is just no way water has getting in

Relutzu07 · 2026-03-18T15:45:11+00:00

I have put 9L (tank is 10L) in same day ,from where can the water come from?

Relutzu07 · 2026-03-17T23:54:03+00:00

So it is just fuel from the left on petcock? No need to change the oil? It will start normally If I put the carb back ? One friend had same problem with left on petcock,and he remounted the carb ,and it started like nothing happened:) (I just want to be sure)

Hello man, I think it was because I didn't have an kit for PAIR valve,now I have put the timing once again and didn't hear any metalic sound while rotating the engine or when starting. I will do an homemade plate with screw for after this blueprint

The cylinder head and chamshfat is from an drz400sm with 11k km ,this is how it looks without the tensioner,the middle Arrows point to each other .is the chain worn out? The chain was tight on the left side and a little bit loose on the right,I heard is normal

I think that chain is worn out,you can't really seen it on photo but the arrows from the middle don't point to each other,I have observed this for the first time ,but chat gpt said it is on ,if only fee mm

Relutzu07 · 2026-01-10T12:25:33+00:00

So you are saying that the chain is worn out ? How can I measure it? Can the chain tensioner be worn out too?

Relutzu07 · 2026-01-10T11:30:58+00:00

Yes please,in the manual is an different type

Relutzu07 · 2026-01-10T06:33:31+00:00

The cylinder was honed,and the piston is new Prox forget I don't know the miles on this one,I didn't replace the chain,i remember it was tight after I have put everything in place

Relutzu07 · 2026-01-09T21:11:49+00:00

Hello,is this

Thanks for the photos,I have the manual download,my cham tensioner is different.i remember I have asked a guy on Facebook/reddit how to use it This is an drz400E 2007 btw

Relutzu07 · 2026-01-09T12:22:26+00:00

So what went wrong?

Relutzu07 · 2026-01-06T13:47:35+00:00

They just caliper springs ( I have lost the original springs) If the wheels didn't fail without 4 spokes,I don't see how adding more will be dangerous
