The Beast is done!

Well all the fab and pain is over.

If you want the full down on my exhaust fun there is a thread on the forum called the "the crazed spitfire.

Remade the short pipe off the collector from some 2.5" and as detailed on the forum VASTLY improved the constriction at the end of the collector where it means the main pipe.
Plenty of work into this, but it's all there now. Just needs a few more tack welds and take it off and send it for TIG.

Really it's perfect, millimetre perfect in everyway, its worked out really well. Labour involved is unbelieveable!

Finished the silencer too, welded, constructed, packed and fitted ready to run...

Need to paint the manifold or get it coated, then it's just a matter of slitting one join pipe for a clamp, final polish and sticking some sealer on and clamping it up.

Need to get my engine bay valances coated too and fit those, I DO want it all done before it leaves the garage. There are some small jobs like welding in a lamdba sensor boss and sorting an airfuel gauge first, I want to see whats cooking with the engine from the offset.

Bit more fettling on the ignition and carb front before I drive it also...

Silencer

Bit more polishin.
Two halves of silencer skin welded by Bob Hall with TIG. Neat job on 0.5mm stainless.

Polished a bit.

Polished a bit more.

V-bands back in stock...Now I just need get all the pieces here and the job is complete.

Furious Polishing

Furiously polished. No I didn't use Autosol! That might take around 4months of solid work!

Before and after.Cloth wheel and soap, normal business.

Makes light work of this job, still a couple of hours of polishing!

Delays on my silencer shell, cause the guy was snowed up at home. No biggy.

This and That.

Now really running out of evening jobs.

Fitted the brake pad retaining pins and rattle plates.
Cleaned my front wheels and waxed them. Stuck some CV2 grease on the studs and torqued the nuts down to 68nm.

Got under it with a torch and really really looked hard to find any weaps or leaks and found none.

Slight petrol wiffage in the boot if you leave it closed, so removed the pump and resealed the NPT connections with epoxy. Wasn't quite happy with my Metro fuel sender, on the empty there is an 8litre reserve, so adjusted the sender, by benind it a bit, yet to recheck it.

I have all the parts for the exhaust, bar the V-band clamp (out of stock).

The place made a hash of the pipe I had made, however with 2.25" removed from before the sill 90deg bend it will fit perfectly after some adjustments.

This bit is fine.

Silencer skin is off being TIG'ed, should get it back tomorrow I can assemble the silencer over the weekend and weld the pieces needing joining.

Sorted the crankcase breathers by running them into the filter backplate. No oil will come out anyway.

More running

Totally complete bar the exhaust. Everything works fine, perfect, not a single snag.
Wanged this on to quiet it down :)

Bit more tuned and fettled. I have given the cams about 15mins @ 2250rpm.

Next run I will lower it to idle speed and tune the idle mixture. I then await an exhaust and I can see how it idles...Might have to play with the exhaust cam timing a bit, cause I like to see the results of stuff, it helps you learn and understand and gives you knowledge, I can get a handle on something I have never done before...? I set it to what it should be from the pipercams book, but the compression, exhaust, carbs make it no more than a guess really, the spec is not "normal". I doubt it will be hard to setup.

Engine sounds strong, very smooth and low vibration. Plenty of compression.
