    Thanks plenty more to come yet.....next plan is to build up a new front wheel with an 8inch drum brake for some more stopping power along with some other tweaks

    Oh, i know exactly what I'm gonna find lol..
    Mismatched conrods since it was what i could find 15 years ago and one small end was toast. Had a new bronze bushing made for the timing side, fixed a few pulled base studs, guess its due for the rest now. Anyhow, last time i checked the main bushing was getting well worn and vibes have increased. May as well have my engine guy have a good look at it when i bring him the boxes. He appreciates getting everything disassembled and degreased lol.

    Loud exhaust to be expected as since its straight through......but no good for the planned track day with an imposed noise limit of 105db, bought some slip in baffles which has helped some, looks to now be right on the limit so maybe some fibreglass insulation wrapped round the baffle from the loft with be the ticket.

    Had varying results with that kind of baffle. Noise limits have been an issue at British circuits for a long time. Brooklands Cans were the answer years ago.

    Must have worked:

    The Tiger 100's sporting pretensions were later further proven through Freddie Clarke's 1939 lap record at Brooklands of 118.02 miles per hour (189.93 km/h) on a bored-out 503 cc Tiger 100.'

    BTW- don't use loft insulation fibreglass , the right stuff for silencers is easily (and Cheaply) obtained.

    Track days what an epic idea, so come the day set off early and arrive around 8 at Castle Combe, dry weather so all good. We were in a group organised through the Brooklands Museum so a cross section of old bikes, Combe is a fast flowing circuit with some chicanes added to slow up the bikes, there were cones out to show turn in apex and braking locations but to be fair my plan was to stay on the bike and feel my way in + the engine was run in but untested in track condition ( bit like the rider
    No real issues during the day Noise test passed no problem, the plugs look very white after the first run and although the main jetting felt ok on the road it was clearly too lean, we carried out a couple of main jet changes ending up with 320 but there is more playing to be had when the rider gets up a few more brave pills. The bug has certainly bitten and with this in mind I am now have some new crankcases and all the bits to do a bottom end build so I know its history - some of the old engine will be used like the crank but I want to see what cams its currently running before I make that choice. Anyway here's some pics from the paddock

    Things have taken a few twists and turns recently with the ST developing a misfire and dumping me at the side of the road.....good job its light for the push home So simple these bikes not much to go wrong found the timing wheel had slipped on the mag taper and on closer inspection ( it was an alloy replacement fitted when i bought the bike) to have a hairline crack not the main issue but added to the fun...

    Friend sent me a STD timing wheel with the fibre wheel but steel centre and after some fun a games on the lathe I had made up a steel centre alloy geared timing wheel so stage 1 complete.

    Then the real fun started - check spark Nope, take the mag ( Lucas K2Fc ) out try it on the bench Perfect spark even jumps a 5mm gap, return to the bike & check for spark Nope, rinse and repeat till your convinced you have lost it, put it in the post back to the guy who rebuilt it a while ago but no real miles see what he could find. While this was going on had another job checking the clutch pulled the centre out and found the internal splines had more wear than I was happy about - this type come apart and have the rubber cush drive but buying parts looked to be more expensive than buying the whole thing so......why not buy 2 so I have one for the other build.

    So clutch got a rebuild and in the process a new tab washer and securing shouldered nut so that should be that, also had a tip off of another mag for sale which had a recite for a extensive rebuild good price so pulled the pin ( always sell one later - sun is out you know the score)

    New mag arrives looks good guy has spent the asking price for the rebuild so looks a good deal - had to make up new leads as the old ones when with the old mag just in case, all fitted up and timed just need to do the kick start thing, in other news the old mag had a broken wire to the condenser which was potted in the windings so causing an intermittent spark.....so at least I am not going mad this needs a complete rewind so 5 weeks out but he's doing it under warranty so lets see, this one has the manual advance where the new one is fixed so maybe a change back when its home again.

    So the suns out and all it needs is a good kick I hope - wish me luck......

    Various stainless steel wools are also available.

    I meant stainless designed for purpose. (The car people have the cash to sort that out so greater variety is available than formerly.)

    Realistically the glass won't wear out for a very long time but I mention because other builders may have use for it. Many UK vendors offer it and it's not expensive.

    Interesting offerings:
