The Tiger performed well in what was essentially its running in period, a busy four days riding around mountain roads, some off road, in the Pyrenees in and around Andorra. Apart from some rough running at higher altitudes the bike ran really well> The handling is great apart from a lack of damping in the rear shocks, these were bought used so no big deal.
Oh and the paint has been finished at last! Candy Orange over gold metallic with black metallic side panels:
Here are the settings that I used following advice from http://www.motocarb.com
270 Main jet
30 pilot
159 -p4 needle jet
6DH3 needle
The bike now starts easily and rides really well, I took a 6 mile test ride. Not 100% perfect but a base I can work from. Pilot jet might come down to a 25.
I had trouble getting the Amal set up right. it was hard to start even after many experiments with float height and so on. I also don’t care for the puddle of petrol after every “tickle” I then found what looked like a crack in the manifold so I bit the bullet and bought a Mikuni kit complete with manifold. Bought from Lowbrow Customs in the US. The only UK distributor I could find was Allens Perfomance whose website as of March 18th 2015 said “we are closed for Christmas” they did not answer the phone and their are no prices on the web site. I concluded they must be going out of business so went elsewhere.
Actually I should have gone to http://www.motocarb.com who are in the UK and very helpful.
Anyway the new carb arrived and was easy to install BUT be warned, if you do buy one of these kits for a Triumph TR6 650 or TR7 750 you have to realise they are NOT jetted specifically for that model. You will have to experiment with pilot jet size and needle jet and needles.
Here is how it ran with the carb “out of the box” it started first kick on the “choke” but was obviously VERY lean running, backfiring through the carb and so on:
I have a reg number for the bike and I have been able to ride it around the streets of South London. Here it is resting after visiting friends and before going back into the bike cave:
Back home:
Here is the “Swift” digital speedo. This has to be calibrated by riding over a measured mile. I guesstimated it to start with, completeley wrong, rode to MoT and back at 150mph…
Today I took the bike for it’s MoT (the annual check on roadworthiness) and it passed! Now I have all the paperwork I need to get the registration number and then I can actually ride this on the road!
I am almost ready to apply to the DVLA to register the bike so I can ride it on the road.
When doing this the DVLA will want proof that the duty and VaT due on an imported vehicle has been paid. This is normally provided by Her Majesty’s Customs and Excise (HMRC) I have no such paperwork and I had bought just the chassis and an incomplete engine.
I phoned the DVLA and they told me to email HMRC explaining the situation and attaching a filled in form C384 with all the details I had. I explained how I had built the bike up over the years after starting with just the frame and engine. After a few days I received a letter from them saying they were satisfied any duty had been paid and I can go ahead and register the vehicle. This was a pleasant surprise as I expected them to present me with a bill for some arbitrary amount… Here is the letter:

Have installed digital bicycle speedo. Have lost clutch inspection cover so have ordered another. Double checking all nuts and bolts. Needs dynamic timing strobing…
Needs front mudguard lower stay, small weld to steering stop, rear brake pedal position needs tweeaking.
