FWIW, I have heard that the spring under the flint of a Bic cigarette lighter is the right size to go under the pins in the TGPI switch.

Excellent! I’ll get one of those to replace the one I basterficated.

Exhaust, trial fitted and modified. New steering head bearings fitted and handle bars installed. Rubber on rims tomorrow.. hopefully.

The rims got rubbered



Rear disc mounted, rear calliper rebuilt and installed, speedo pick-up cleaned and installed, rear wheel mounted.







Tailpipe Mount finished, awaiting some springs.



Happy with how it’s looking. Need to order some valve shims before the week end.

Valve clearances?

Like Mr Harris used to say “loose is fine, if they’re loose, leave them the fcuk alone”

I’ve just measured mine, none were tight but No.4 Intake, and No.2, 3 & 4 Exhaust are over the maximum.

So, is over max bad?

Intake #4= .225
Exhaust #2= .406
Exhaust #3= .432
Exhaust #4= .381



Thoughts welcomed.

Right! Obviously, the reason varies according to the state of your personal and spiritual development.

One reason is that it's the best word to have as an opposite meaning of minimum because it is also a three-syllable word with the same number of letters and sharing the letter m at the beginning of its first and third syllables. The fact that it contains an X should be convincing. Maybe it would be more convincing if it were spelled with XXX, but that would move it into the realm of porn and into a different set of variables.

There is a belief that excess lash can cause premature wear of valves and valve seats. The engine is bound to be noisier. What's the payoff of not setting it to spec?  If I'd invested as much effort as you in restoring a bike to this extent, I'd be going by the book.

Hi mate, ride it hard and you'll soon bring those gaps down. The only problem with oversized exhaust valve clearances is a minimal loss of compression when engine braking and perhaps a little fuel in the exhaust for those big pops you wanted when you ordered that tuba of an exhaust.


Happy popping

To be honest I would probably ride it for a few months and see how it went. If your unhappy with the ride or if there is excess valve noise then you can always take the cover off and change the shims. On the other hand if it's ok you may decide to live with it. On a bike with 44k I can only think that they were set high in the first place. Mine were pretty spot on at 60K

It’s been a bit slow lately, got a lot going on at home. This is a weeks progress I guess.

Got the front wheel bearings installed, discs on and wheel balanced.



Installed the rebuilt forks in the triple clamp. Cleaned up the nearly new stainless brake lines. Rebuilt the front callipers with new Brembo seal kits and stainless bleed nipples.







Replaced the Engine, Gearbox, Final Drive and Fork Oils... 330cc/330ml didn’t ‘feel’ like enough for the front end  :dunno2:

Over the rest of the week/weekend I’d like to get round to investigating and hopefully repairing the stuck rear master cylinder and hopefully fitting the right hand side sets. Create and install the custom expansion tank and add some coolant, then  make a start on refreshing the main wiring loom/harness.

Please excuse the lack of updates, I have a family member in the hospital.


I was trial fitting the aftermarket headlight today and see it requires a H4 bulb. I can obviously install a standard filament bulb but I see the LEDs are equally priced. Can anyone tell me if I’ll have any issues installing a LED H4? Will there be a need for resistors or such like to be wired in also?

Thanks in advance

Hi Dave


Depends on the headlight. Some come with the load resistors built in and others don't. Should be written in the leaflet supplied.

Hi Skunky, nothing built inline. Thanks for the information, I’ll order a standard filament job.

While you’re informing- I’ve got LED indicators, is it just a case of doing the hyper flash snip to the flasher relay to combat these once wired? (I read this about 6 months ago so may be incorrect)

Skunky is having issues. I'll intercede. LED indicator success is just a snip away, as long as the correct trace is snipped. There are plenty of illustrations although the orientation of those might vary slighty. The thread has the info. It's still valid.

Due to a custom part not arriving, I had to re-think my custom expansion bottle plan. It now consists of a Aluminium 500ml matte black camping water bottle. I drilled a hole in the bottom and fitted a 90 degree 1/4" Hose barb.





I have yet to decide how to secure it, its naturally quite snug where it sits perched on the radiator hose with its size and with a cable tie through the lid and the frame  :giggles

The quality of this idea does not match the effort you have put elsewhere. Is it temporary? How will you check the coolant level? It's best not to overfill or let it diminish excessively. One of my favorite custom designs is in this post's photo array.

Agreed. I can't believe he chopped that K1! :yow  Yeah it's a cool reservoir, a bit loud for my taste though.

It is temporary while the ongoing saga of "where's my fucking bit" continues. It may very well end up with 2 more 90 degree barbs at either end being tigged in with a clear tube crimped between them then fixed to the bike properly. For now, however, it'll get me through to first start and tune.
