Re: Show us your 45

The rear fender won't be on the finished bike, it is too big a radius... Just a little flat one like a WR. The square steel box in the left foreground is going to be the battery box, it's a WW2 era field telephone battery case that I've had knocking about my workshop fir decades. It's just the right size and will slot straight in.

I like the beefy appearance it has with the 16's.

Ah the time spent in getting it right. But getting it right is the goal.

Re: Show us your 45

It isn't obvious from tne photos posted but the rear frame has been much cut about in a past life as a chopper, although the neck us uncut. Quite a lot if work has gone into making that good and strengthening it. I Have kept the 1" neck conversion, as it is a nice job, hence the Shovelhead forks. The rear wheel was 16" already so I kept that and matched it to the Shovelhead one that came with the forks. Banana caliper from the same source; I like a decent front brake and a banana caliper is plenty for a 45, after all.

Toolbox will be a knucklehead one originally intended for the Ariel framed bike. Back stand because I like them. Stock exhaust because it came with the parts pile for the bike, along with all the chrome repop foot boards etc. Tanks are OEM but I think they have been rebuilt, sometime in the past. However past frame mods have resulted in the dash mounts being lost, including the speedo cable sleeve being cut back and welded up so I aim to cover the space and fit a small speedo driven off the original Shovelhead frint wheel drive, wherever it will fit.

Buddy seat because I scored it for £50 on eBay and like them. WR solo seat if I feel like it because the other bike has one.

I wouldn't say "getting it right", it is more a case of the bike growing organically from the parts that came with it!

Project is just beginning. Lots to do. Just need to get home so I can make some headway.

Brit gear box, foot clutch, hand shift, etc.

Re: Show us your 45

Digressing slightly, but the rocker/suicide clutch question is to some extent related to differing styles of riding across the Atlantic. British traffic lights have quite a long "amber" and almost never go straight to green, so sitting at the lights in gear with the clutch in is not favoured - indeed you will be marked down for it in a driving test because it is regarded as dangerous.

We drive on the left, so your clutch foot is on the near side, down-camber side of the bike, which is the side you may well wish to out down

Another thing is that speedway, although very popular at times, is not really regarded as a "motorcycle sport" and very little reported in the bike press. Brake less bikes are regarded as an aberration, not a mainstream trend - remember that none of the main factories made a speedway machine after about 1932.

Re: Show us your 45

so, the stroker bike is back on the workbench

here's the piston oilers, T&O pistons and rods... no baffles! Hasting 3-piece oil control rings to follow.

Re: Show us your 45

Interesting setup 45brit.
How do you keep piston and cylinder skirt clearance to the skirt oiler?
Cut off in both?

Re: Show us your 45

That's correct. The design is based on infirmation posted here and eksewhere. Location is defend by having enough metal under the nozzle to ensure the integrity of the thread.

Haven't finalised where the feed will be derived yet but as I'm intending to use the Swedish Gerotor pump and high-flow return there should be some options.

Looks nice, clean install. Interested in how things work out with the gerotator pump. It definitely makes for a smooth installation.

Re: Show us your 45

Very nice looking piston squirters. I would do something like that if I did it again. On the Swedish gerotor pump there is a 1/8 npt plug that works good as an oil feed for piston oilers, however it is not controlled by a check ball. I put in an inline check valve that I got from McMaster-Carr and it worked for about 500 miles and then I began to get wet sumping. When I disconnected the oilers the wet sumping stopped. I am going to put a manual valve in the line this winter to solve the problem. The pump has plenty of capacity for the oilers and with them shut off, I am a bit concerned about excess oil pressure. The oilers bleed off enough to put pressures about where they should be.

Re: Show us your 45

There is a post somewhere about having a pressure relief valve to control the oilers, I think 20psi was mentioned?

I've also seen mention of using a tee from the return line. I'm normally reluctant to divert oil from the feed line but it seems there is plenty of capacity. A return-driven supply would prevent wet dumping because the oil tank end if the line is above the level in the tank.

Re: Show us your 45

45brit
I must say your setup looks very clean.
Have you considered milling of the pistons on both sides leaving a narrow tang on the trust faces? By doing this you will have symmetric removal of material from the piston and also give room for the oiler. Of all the 45 pistons I have seen, there is never sign of wear on the sides, so why not remove this metal as long as you don’t hack of so much that you compromise stability and strength of the piston. This is being implemented in the motor I’m currently working with.
I have installed a valve on the line to the skirt oilers to avoid wet-sumping. Not so critical of I forget to open as it only blocks of the piston oilers. But I always remember as the manometer tells me…

Re: Show us your 45

I hadn't thought of milling them down to, effectively, slipper pistins, no. There's too much work in that engine already and I want to see hw it goes, first.

There is a possible later version with 38mm inlets and oversize valves, and THAT woukd be the time fir radical piston work.

Re: Show us your 45

just picked this up today. 54" stroker, #6 heads measure 6.5:1 compression.

Gerotor pump hasn't come yet so engine has been assembled with the stock pump and the squirters connected, I have a pressure gauge to go in the line. Aim is to build up the bike next leave
