@NINJA thanks for that the link has the manual. Hopefully sort it tomorrow

[NINJA]

@Louis-James You're welcome - I'm not sure if they are for your model, as there's quite a few to download online. Just do a search for your model/year and you'll probably find the correct one???

[DTR+NSR]

Is the clutch hub and basket lined up correctly seem to remember you can fit the dt one 4 different ways but will only work in one position

[Louis-DT-WR]

@DTR-NSR thanks guys it's all sorted now.
Good thing I checked because the water pump didn't have a gasket in there
This is what happens when other people rebuild

[NINJA]

@Louis-James A bullet dodged there dude!!! :thumbs_up_light_skin_tone:

[Louis-DT-WR]

@NINJA yes, this engine had a fair few leaks I sorted today

Oil pump

Gear lever seal

Water pump.

Also putting the water pump pipe back in caused many problems, took so many attempts to get it to seal.

But now have a fully functioning to 2stroke pump .. as it was from the factory.

[NINJA]

@Louis-James Nice one, I feel your pain, as I've very recently been there myself. :pouting_face: :pouting_face: :pouting_face:

It sounds like either a lot of gaskets have perished or not been fitted properly in the first place? Either way an overhaul of em all may be prudent???

[Louis-DT-WR]

@NINJA always when someone else does work

I've thoroughly checked all over. The top end had been rebuilt with a wiseco piston.
I did check that.

But one of the last bits done to the engine was a new clutch and water pump seal.

[NINJA]

@Louis-James Well hopefully the only bumps you'll see from now on, will be the ones you are jumping over MX styleee!!!

[Louis-DT-WR]

So the oil pump was not flowing. Took it off and the outlet was block. Removed the hose tail and I drilled the smaller bore. Oil now flows through.

Without taking the pump alart again I am unsure if I have drilled too deep and the oil is bypass internally. By blowing through it and operating the throttle.. it doesn't seem to flow more or less on throttle position. Does there need to be drive to the pump and is it a variable gear inside is what changes the flow?

So going to have to inspect.
Or compare to another.

Also bike cuts out when put into gear with stand up or down.. I think it's a faulty sidestand switch
A few little things to sort

Anyway.. a few pics

[Calum]

Bike looks superb. Done an excellent job there. Definitely will be on that infamous hall of fame...

Yeah side stand switch is common on all bikes. Should be relatively simple to figure out.

Hopefully it's the switch and not the CDI.

Yeah pumps can be weird to diagnose, better run premix whilst you're figuring it all out!

[Louis-DT-WR]

@Calum thanks a lot man.

It didn't have a side stand switch before.
It was looped (wiring present) but I bought a universal switch. I'll do a circuit test on it.

Yes I'm running premix arm. Engine is sweet!
No leaks!

[NINJA]

@Louis-James The bike looks mint bud - TOP JOB!!! :thumbs_up_light_skin_tone:

Have you ridden her yet???

[Louis-DT-WR]

@NINJA thank you
I rode it before I stripped it down.... rapid!
I've just got a few little things to sort out before taking it for a proper spin

[NINJA]

@Louis-James COOL she should go better with the upgrades, let us know how she handles.

[Louis-DT-WR]

@NINJA will do not too keen on knobblies on the road.. but definitely suits it physically

[NINJA]

@Louis-James She's an enduro, so she should go anywhere you wanna take her!!!

[Louis-DT-WR]

Here's a running video.

That oil pump was definitely blocked inside the casting..
Got another on order.

[NINJA]

@Louis-James She sounds just like a proper 2 stroke should!!! :grinning_face_with_smiling_eyes: :grinning_face_with_smiling_eyes: :grinning_face_with_smiling_eyes:
