Thanks for the offer GB! I have ordered the one from Spain that AL put me on to so i will try that one first and hopefully it works. If not i'll get back to you thanks.

Obviously my ebay search skills are wanting :oops:

Whilst putting a few miles on the bike i noticed that there was a gap appearing between the end cap and the can of the exhaust. The baffle is a sliding fit in the outer tube with a pressed plate welded to the inlet side and the gas pressure is forcing the baffle and hence cap, so it needs to be held in a bit more securely.

First was to try and locate the baffle by drilling through the outer tube and into the flange of the pressed plate, then cut a thread in the hole in the baffle. This should stop the baffle creeping rearward :shock:

Held in by an M6 button head:

Then measure up for a second screw to hold the cap to the outer tube:

In a previous post i mentioned that the green Dyna coils were a tight fit under the frame rails and i had to find a solution to this. There were other problems too:

One of the HT leads was always trying to work itself out of the coil due to the tight bend it had to make exiting the coil and miss the top frame tube.
I had already blown a fuse once due to the crazy design of the coils placing the LT terminals directly next to the (earthed) mounting post. I had got around this by insulating the terminals and post with insulation tape. i.e. a bodge
When i made the loom i had not fitted the coils, and when the coils were fitted the only place for the loom and its many bullet connectors connecting the main loom with the head loom was squashed in between the top frame rail and in between the coils. This then caused the main loom to be stretched and effectively too short straining all the connectors along its length and causing them to be pulled out when turning the bars :oops Schoolboy error again.

I also suspect that one of the coils is not operating correctly under load and causing the misfire that makes the flat spot in the carburation worse and harder to tune out.

Solution to all this was already sitting in my parts bin for the P&M:

New HT cables too. I like the look of the old style NGK plug caps. How they perform remains to be seen:

IMG_20171203_133758.jpg


The loom is now a better fit around the battery area under the seat but still needs tidying:

IMG_20171203_133816.jpg


I set the ignition system to test mode so that the coils continuously fire. At this point i noted that 2 of the plugs were not sparking across the electrodes but to the side wall - cracked porcelain insulators. So new plugs also went in.

Now starts first press (when the starter clutch allows) and runs much smoother. The huge flat spot just off idle is still there but i am sorting this out soon. There's salt on the roads now so its not going out for a while anyway, so i decided to pull the front end apart awaiting the new bottom yoke from Mikey:

Picked up some anodised parts from Mikey:

Bottom yoke, headlight brackets and rear brake torque arm:

Gotta say he does a perfect job. This is one service supplier i am very happy with :D

Spent an hour or so pressing the stem out of the R6 yoke and into the new one with the bearing and spacer:

Needed to turn down the stem slightly for thicker than anticipated anodising, but she went in with a bit of juggling :tooled

I designed them and had a local CNC company make them, then got them black anodised.

They are for 53mm USD forks but could be designed/made to fit any size.

Got me fork extensions back from the machinist:

IMG_20171223_131313.jpg


Internal extension fitted with copper washer to stop any bypass:


IMG_20171223_140233.jpg


Top extender fitted with new o-ring:

IMG_20171223_140542.jpg


Screwed in as tight as i could get it, but its not going anywhere once all clamped:

IMG_20171223_140640.jpg


This now gives me 30mm more fork length to play with.

All finished with new seals and 26ml additional fluid to each fork.
