Just to be clear, have you removed the thermostat? the bypass between the water pump cover and the inlet manifold is blocked off? Have you a Davies Craig controller fitted? thanks, Ian

Attached are some photos of my set up see if anyone can work out whats going wrong.

DPF? Mine was pre-DPF.  Great on the highway when someone tailgated me. Drop it down a gear and plant the accelerator. 

Ah! Diesel. I bought a VW Jetta turbo-diesel new in 1991. It didn't get the kind of mileage you're seeing but it was at least 50% better than the petrol version.  Kept it for 10 years, put almost 400,000 Km on it. Did the exhaust a couple of times, a couple of alternators, glow plugs, two new batteries. I sold it used. It passed certification without any repairs, before I put it up for sale. Original shocks, springs, suspension, bushings, engine and transmission. I don't think they build them that well any more. Mine was one of the last German built ones we got here.

For my mark 4 the steel bonnet was 36kg, the grp one is optimisticly 20kg.  This is ready to go weight, i.e. steel frame, headlight, and latches included.  Yours is a meaningful improvement, looks fabulous, and actually fits!

Update: I have figured out the issue with not allowing political threads over there. IE: The difference between not allowing them there, and allowing them here, is not the "topic". It's the members.  I think political debate can be discussed civilly by a rather large range of voters across the spectrum. However, this is not the case if there are also members from the MAGA portion of the spectrum. Rather than debate, they stamp their feet, scream, yell and swear at you, and insist the are the "majority" of the site. And, demand the owner to put a stop to it.  Some of those really heated threads last summer.... one of them made a comment to the effect of "well now we know who our enemies are". Enemies. Because of a political view. Great. On January 3, I made a comment in jest in the 3D printing forum to one of the members. A friend. We had corresponded a lot last spring about printers, filaments, techniques, etc. Not just by PM's but by emails and phone calls as well. He replied: "Let it go, Rick". It sounded like I'd offended him so I sent him a PM apologizing for it and wishing him a happy new year.  Never heard back. Until a couple of days ago..... I'm pretty sure BobM2 was the one who made the enemies comment. I notified Skye and sent him a copy of the email.  I also posted it in "The Pub" very early this morning as a thread and explained why I wouldn't bother participating much in the site any more. One member replied suggesting I just ignore him.  Easy to do with Trolls. Easier said than done when it's someone you thought was a friend.  That thread has been deleted as well. I'll hazard a guess that some of the MAGA crew got involved and Skye deleted it before I could see it. https://www.triumphexp.com/forum/the-pub-off-topic.10/2159264#REPLY So, now you know why Skye won't allow political threads over there. "They can't handle the truth!"  I hope for God's sake you guys never get saddled with Nigel Farage as PM. And that we never end up with Pierre Poilievre as PM. They'll destroy both countries. Just like tRump is doing in America.  C'est la vie

Final weight of the bonnet, less the metalwork is a little over 12.5kg. Can't remember exactly the equivalent for the steel bonnet but it's around 32-33kg, maybe a bit more.

It’s an Imgur problem. They’ve chosen to ban themselves in the UK rather than comply with our rules about dodgy content.  If you use a vpn or a browser with built in vpn such as opera then you’ll be able to see the pics.  

Just showing that he’s in the thieving robber-baron demographic and has no idea how real people live. I only have the one house, but I’m not quite retired yet so maybe there’s still time….. (not much I hope!)
