How Many DT's in that video. That's mental.

I bet over there they can actually keep their bikes without them getting nicked left right and center!!! :@

@irongamer727 You can go overbore. Really need to modify the valve when you do. And you can have a new liner put in.

@yegor Yeah, it's gotta be suitable for oil.

They both go to the carb.

the plastic pulley has to aligned with hole to be able to pin it though unless I glue a washer on to the plastic pulley to align it before the hole

@irongamer727 I distinctly remember not using them on my rebuilds, so shouldn't worry

@Calum appreciate the help as usual 👍👍


@Darty Oh yeah, I mean RS's are used to commute from and the stock porting on those are nuts lol

@andrewj1680 said in pinning power valve parts needed:

You could always just stick a big washer behind the bolt that runs through the middle you can lock it off that way which is what I have ended up doing today as since having port work and the power valve modded it kept moving a little over fully open

I ve bought the servo kit I can use the standard parts to pin it now
or if I can get the servo to fit my frame I will use it
(the dt engine is in a different frame ) its gonna be a mission to get the servo to fit I wanted to mount it under the tank but the cables are too short
not sure it will be worth the hassle

@Louis-James thanks mate appreciate it I'll get on it tomorrow first thing, there is nothing wrong with the crank in it but knowing my luck they will have discontinued it by the time I do need it lol always the way ain't it

If you really want to learn more about it then I recommend reading Graham Bell's Two Stroke Performance Tuning. Very good book and will explain a lot.

The Heads do

They also ran a combustion ring which was adverse to performance.

But instead of paying x amount for a 3MB, Mick abbey will correct it for 30 quid.
