What a beast!

If you got the dough....why not.

@DTR-NSR

Yep, I’m definitely leaning towards the 3bond

Hi guys I’ve got a 3BP bottom end, does anyone know what year it is and what crank stroke does it have? As want to run a 3MB barrel thanks!

Old thread alert, but! My servo was doing this when I used inferior 2stroke oil and the power valve was gummed up and sticky. As soon as I cleaned of the varnish/gumpf it operated sweet and smooth…

Did you get anywhere with the bigger single radiator?

@SpookDog Probably get a better response on the FaceAche forums.

Lanze airbox snorkel gotta try and find also suppose be a nice mod

@SpookDog sorry for late reply all in with post was around £20 I think

Just make sure that it’s in there nice and squarely. Also that the ‘insert’ has a good clean finish with no bad grooves or crud buildup on it 🙂
Did you split and rebuild the cases or just replace the seals? (both)...
Just use a proper clutch holder to tighten (or loosen) the clutch centre nut, don’t stick a screwdriver in the outer basket ‘fingers’! The alloy snaps so easy and without warning!...

@MadGyver I have the 3BN head on a 16.9 KW bike

I know it’s an old thread, but: It’s the barrel that gets grooved, not the head (I thought it was head as well) and it is £35 @ PJME according to the email they sent me 👍

@Calum always amazes me how much difference a carb can make to a bike, I always remember my old dt50r when I upgraded the exhaust from standard to performance how untuned the carb was to the exhaust, turned a nippy machine into an sluggish horrible mess

@markus-w thanks for this

@Calum ill bet You £7.50 it doesent 😂 no it's just a project bike haven't ridden it more than 10 minutes at this point

@SpookDog how it smells 🤣

Just dress the curclips with some emery, wet’n’dry or a Dremmel so there is no sharp edge 😜

PS or just use the back edge of a pair of scissors and run that round the sharp edge, anything that is made of good hard metal...

I don’t think the edge even protrudes tho’ So it shouldn’t wear anything at all...

I cheated out and reused the same clips when I stripped, cleaned and rebuilt my box. No issues with it. I would replace them if I could find same quality parts. No fleabay cr@p!!

@markus-w

That’s what I think. Just from my experience with my bike (1988 with a 3mb barrel)
