You’re a genius haha that’s exactly what’s happened, there is play in the pv. Am I ment to place a bolt through the hole to tighten it ?

Are you hearing the rattle about a second after I let off ?

It’s heard on all revs but the first

Hi all, this bikes a constant headache and it’s newest addition to the issue list is this strange rattle that the bike makes when I get off throttle and let the revs drop. I have no clue what it is and I’ll attach a link to a video of my bike to demonstrate it

heres the video

Any help would be amazing I’m honestly just going to sell it once it’s all working fine

I think that will be the plan for now. I’ll get the barrel off and order new studs and I will check the reeds too

It was a black/gray one from a top end kit from yambits but even when I installed it it didn’t leak coolent but didn’t hold compression

Gorgeous bikes, they’re one of only a few bikes I wish I had instead of my dt

Is that not too uncommon for them to go that soon? As I’m starting to worry it could be something else causing them to fail so often

And that didn’t last long …

The gasket has started leaking already after maybe 80 miles. Going to order an Athena one later tonight and I was wondering if it would be worth skimming my head and barrel mating surfaces?

I had a spare head gasket from the gasket set I got from yambits I know it’s not Athena but I’ll order one up and it’s on now and seaming to be fine thank you lot

Standard barrel and derestricted but factory head and I torqued them to the best of my ability due to the tight space some of the bolts are in

Yep right way up and Athena from PJME.co.uk

I replaced the head gasket and got the head machined flat and that was all good … for about 500 miles . Now it’s started doing it again but this time the temps arnt shooting up

You’ll need a full electrical circuit and a battery to run YVPS as its intended but I’m sure there will be a workaround

Sorry if this is in the wrong section but I’ve been trying to find an answer to this question and I can’t find a clean cut answer.
I’ve got a 99’ Dtr (my first proper bike) and run the oil injection as well as a cap on oil in the tank. Will me engine braking damage the engine ?

I was just looking at my Engine as I have a coolent problem when I found this hole on the bottom of the engine but it looks to uniform to be damage but still looks wrong

There’s a picture of it, it is directly under the top end

Yes it’s loosing cooling from the radiator quite a bit

@SpookDog would this not contaminate the coolant as I have never seen anything in the coolant and always drains perfectly clear

Been working on it all day and we have since found it wasn’t the water pump still trying to figure it out haha

Update.

so i have a reason to believe that its my water pump that has failed, does anyone know how to test the water pump before removing it ?
