billet rocker oil feed pipe

does anyone know where I might get a billet rocker oil feed pipe for my B44, the only one's I can find are for twins, I'm sure I've seen singles fitted with them so they must be out there somewhere.

B44 scrambler

I bought this thing a few years ago, it had been brought back from the US, well, what was left of it.. the forks were solid rust inside, and the oil pump had seized due to lack of oil! basically a complete dog, all that was useful from it was the frame, the crank cases, the crank and the head. https...

I've got a spare brand new (still boxed) std JP piston assembly for a B44, don't suppose I'll be using it as I've gone with one of Mark Cooks pistons.

Just as an update I've now found a B50 hub so hopefully problem solved...yes it was hot wasn't it, on the way out we stopped to give the chickens by the gate our water, their bowls were bone dry, poor little critters.

Bantam front hub for scrambles?

with regards to my intended foray into competition this year it seems that the early XL250 forks and wheel I currently have fitted on my Victor wouldn't be acceptable under AMCA rules...a real shame because they certainly look the part and it handles just fine. so with that in mind I've had a root a...

Transponder location

a question for you scramblers etc out there, where do you mount your transponder, if you use one? I'm intending to start competing this year and was wondering if it needs to be at the top of the forks or is there a better place?

I do like the idea of your "hydraulic device" very inventive, I think my only concern with it would be would the grease gun stay on the nipple?

Thanks for the offer, I'll check the length of stroke tomorrow, I'm not sure that a degree wheel is as accurate as some folk think, seeing as you have to start off with TDC anyway and then rely on a printed bit of plastic somehow attached to your crank end and measured by a bit of bent wire (usually...

B44 ignition timing

does anyone know what the 34 degrees BTDC for the B44 equates to in height of piston down the barrel from TDC ? I dont like fiddling around with timing discs and as the head is off at the moment in means I can get a far more accurate setting if I know the depth of the piston at 34 BTDC.

Re: Rear chain length (no. of links)

Maybe easier to just buy a 120 link (usually the longest you can buy) 520 pitch chain and just knock a few links out to suit, got mine for about £28 as I remember, like Minety said you may need a half link in there possibly as well but they're cheap enough.

Just out of interest I've just found a way of getting an obstinate ball out of the rack, I just put a blowtorch on it for 30 seconds or so, the ball popped out and shot across the workshop! it turned the grease it was seated in with into gas and expanded I reckon.

No, it's like I said in the original post, 7/32" is quoted but there is no way it will fit, I've got a few and tried them, they just sit on the top of the rack, I have two outer covers and both have the rack machined for a smaller ball, as Midgie said, 5/32"
