Today I started with the tank liner removal and preperation for the new liner to go in.

I used an offcut of a wheel tube and a small offcut of aluminium plate to blank off the fuel tap hole.

Then the Caswell liner removal solution went in to disolve the old liner, I guess the solution is MEK or cellulose, it seems to have done the job. Before emptying the chemical out I threw in 20 wood screws to loosen up any stubborn debris, after a good shake a small pinhole appeared and was literally covered with paint so a little bit more of soldering to be done.

Before that happens Ill rinse out the tank with soapy water to expell the chemical vapours. Thats for tomorrow though.

I decided to address the fuel tank yesterday.
There were holes around the fuel tap which obviously had to be sorted.
I removed all the paint and tapped in around each hole to create a well
for the solder which I used to gather and plug the hole.
I used flux core solder, seems to have worked well.

Next step now is to remove the liner and replace with a new Caswell one.

Thanks Czakky

Fitted a new chain roller on a 6mm aluminium plate and fixed to the rear of the rearset mounting bolts. Its fixed in position rather than a spring loaded idea.

last night i made up some swingarm bobbins after getting a set of hooks for the stand.
I was using the flat pads but the bike kept slipping off them. made some spacers too to minimise scratching the swinger

thanks pidjones, I got it sorted today !

it turned out ok, i cut the front panel, rotated it 180° and plastic welded it back into place using off-cuts from an old MTB mudguard and a soldering iron!

i took a gamble and left a bit of space between the bottom of the air box and the bottom of the rubber mount to enable fuel to collect if it has to.

anyway carbs mounted and the welds didnt break!
The 5mm reedblock spacers mean I need to remove the airbox to get the carbs out and especially to get them back on when the time comes.

so here is what im planning for tomorrows session.

im gonna modify the airbox by cutting the front panel and re-installing the panel 180° so the airbox to carb rubbers line up.

I estimate a difference in height of 12.5mm.

By rotating the pice cutout there will be no need for infill pieces. I can either plastic weld the panel in or I can use epoxy!

carbs built with 15mm float heights and 1.5 turns out with the air screw.

fitting the carbs between the rubbers is an absolute - p i t a!

Had to split the airbox to access the rubbers from the inside. I estimate I will have to tinker with cae carbs to change jets etc. so Im not going to be able to deal with the torture of this so im thinking of a different setup!

Y boot and uni pod...

It also means im going to change to a sealed battery and fitting it in a diferent location as the airbox will be removed.

back to the carbs, finally got around to fitting the 5mm reed block spacers, hopefully this will aid the fitting of the carbs.

The carbs are lined up to get rebuilt after another ultrasonic clean. going to start with standard jets and settings.

thanks wade, ive  ordered an 8mm offset sprocket from vvmracing.com
and a cheap sprung chain roller from ebay to alter the under side chain run,
i will have to make a mounting plate to hold the roller but cannot do that
until it arrives

Hi wade, actually after properly fitting the actuator and side casing with clutch cable engaged/disengaged there is clearance with the sprocket spaced by 8mm!!!!



im happy enough with that,  the only problem i have now is getting an offset sprocket and getting the clean chain run.

Would a smaller countershaft sprocket help with the clutch actuator clearance?

not sure i get it wade?
