V8 trike build.

What colour fuel tank are you going for?

You can tint raptor and if sprayed at a higher pressure you can get it smoother than a roller finish

Just thinking about the mudguards

Probably red oxide first time round, until I work out what it fails MSVA on, then I'd like a spun alloy fuel tank.

I think the rest of it will eventually match the hot rod it's been built in memory off, home made metal flake red. That's the current plan.

Very 70's I can almost hear Scooby Doo. Ruby ruby roo!

It was actually meant to be 60/70's sort of styling.... so it worked.

@Morrisman , saw this and thought of you

Seem that one before, I think, it's quite tidy. If it's the one I'm thinking of it runs through a stock Harley gearbox.

It is a Harley box, it was built by Steve Coe in Florida. No radiator, he just runs it for a few minutes and then that's it. Too much money and time?

Here's his Hemi trike, I think the radiator is round the back on this one.

Yours is looking great @Morrisman

Now that's something, a hemi trike.

I've hardly looked at mine for a week or two, but just this afternoon I started making a move, drew up a 'hit list' of what jobs are left, and sent drawings off to get a quote for some profile cutting for the front fork rockers. Hopefully my mojo will improve with the sunny weather arriving.

Not a lot of progress lately, I seem to have lost motivation a bit, but things are still happening.

Rear brake master cylinder, I cut a bracket, tacked in place. It's a 3/4" diameter but I'm thinking it's actually a Landrover clutch mc. Will it work okay, or should I use a proper brake mc? The mounting hole dimensions are the same for all this type of unit. I only paid a tenner for it off a mate so no dramas.



Also mounted the alternator, along with suitable protection for errant pedestrians, as per MSVA rules. Looks a bit ugly hanging out the side. It may be swapped out for something more petite at a later date, but I had this one already.



I've made a dummy tank, to cover all the sharp lumpy parts on the distributor and carb etc. Not 100% what the rules are, as they say you can't have a filler cap more than 15mm high, if it were a real fuel tank, but a big distributor right in front of the family jewels isn't mentioned in the manual, that I can see.



My Tig welder got pressed into service for this, and it went okay wherever I had real close fitting joints, but not so pretty elsewhere.

These are the better welds..... I hammer rolled the edges around a plywood former with the edge routed into a radius.

If you're using discs the master cylinder may need a residual pressure valve (it's a while ago since I messed about with them, so things might have changed) which a clutch MC won't have.

 

[jsf55]

I thought that was drums only ? there again it's mounted much lower than conventional stuff ? Could you not do a diff mounted alternator drive or it packaged too tight ?

Yep my bad, ignore me I miss remembered that one!

 

[PhillipM]

Sometimes you need one with discs too especially if the MC is below the calipers. You can buy standalone wilwood ones cheap though that just plumb inline.

I wasn't aware there was any difference - a master cylinder was a master cylinder - a piston in a bore. Any I've used, or taken apart to repair have simply been that.

 

[jsf55]

Caught me out when i fitted a master cylinder with a built in residual valve and discs all round, by the time i'd driven 2 miles the brakes were jammed on and didn't know why ... i do now ! It's mostly used on an all drum set up

Drum brakes have springs on the shoes that will pull the slave cylinder fully in when not braking, discs don't. But discs use a lot more fluid so sometimes they need residual valves too.

I have this T shirt from my last trike build. took more than two miles and didnt do it all the time. New wilwood cylinder sorted it.

And a but of useless info, wilwood ones polish up far better than the girling ones

So far not come across one with a valve built in.

I found the email address to send off to DVLA to apply for a VIN to start the registration ball rolling. It can apparently take weeks for things to move, and after spending 25 minutes on hold on the phone I was informed they are taking strike action this week....

Something else I've found, if the motor is manufactured after 1990 it has to be emissions tested. The casting number indicates it was manufactured 95-00.

Any chance this thing would pass such a test, running on a car, and not fuel injection and a catalytic converter?

Or could I cure the problem with a Dremel....

 

[Morris]

It's not a very high bar to clear (unlike the car test) just smoke and CO has to be below 4.5%. Surely this can be achieved.
Edit- just checked and that's the MOT standard for pre 86 cars.
