 Looking good. I'm at a standstill on mine right now, I bought a few bikes to repair and sell to finance my race car and Honda hobby. I'm concentrating on finding a few items for the sandcast right now. We have 2 alky funny car chassis to repair but the first one's a month late getting here. There's a crushed Top Dragster ( A frame hoist in a shop fell on it) waiting in line too, so the work will help pay for things.

Thanks Don  ;). I've been sidelined with two much more mundane jobs than you lately Don . I've had two washing machines to repair  8) 8). I suppose we all have to deal with the real important things in life ( like having clean clothes to wear) before we get to play with our toys eh!  ::) ::).
Bill , I've been looking at all kinds of con rods lately ,even a set of Golden Rods over here in the UK,but one thing you can be sure of though, is that I won't be fitting a forty year old set off ally rods in there  ::) ::). Greg "H".

yeah Greg everyone seems to go nuts over the golden rods but I don't see many people putting them in a motor,as they can be fatigued from hard use ,so there must be a lot of alloy rods on the benches of collectors to admire!I am past the collecting stage I want to use the parts I manage to find on a bike.bill

Well . I've got the domestic jobs out of the way now ::) . The search continues for a suitable motor so we can be up and running for 2015 . Whilst looking I'm trying to find stuff to do on the rolling chassis . I've fitted a repro chromed headlight shell , and a repro chrome rim . I've used a headlamp  decal that I must have had in a box for twenty years or so , to give the bikes front end a proper race bike look .

It's gone cold here after such a mild autumn , and with it being the festive period as well there havn't been many opportunities to get out into the "man shed" for a little "me" time of late . However , I did notice during one of the quiet periods ,ie no eating and drinking and watching the telly ;D, that there was enough mild steel angle and flat bar lying about in the shop to enable me to knock up an  engine stand  . At first I was going to make up a "super  stand" which by virtue of swapping various brackets etc  could be used for both the top and bottom c/cases .However, after standing for an hour in the freezing workshop with my hands in my pockets , I finally decided to make two stands instead ::).

Hi Greg,
I really like the bike mate, having the headlight in the drop bear spotting position is definately the way to go  ;)
Totally agree putting a stock motor in, a reasonably healthy motor and your set up should run you into the 13's I would think.

Hi Adam . I've missed out on a good stock  motor which I could have heard running :(, and I've let a couple go cos I only had the sellers word that they ran o.k before they where taken out  ::). You're right mate , 13s shouldn't be a problem , (not exactly quick ) but at least I'll be getting to use the bike and checkout if it goes and stops in a straight line  ::). I'm pretty sure I'll get my hands on a decent stock  motor before spring 2015,so in the meantime I'll just have to keep  researching and looking out for suitable bits for the race motor. .

Your not wrong Stev-o  ;D ;D. There's a fair bit of water gone under the bridge since I made that statement  ::). After all , it's all about the journey,right!  ;) While I'm waiting for the good stock motor to make an appearance ::) , I've decided to strip the other F1 motor that I have .

Well, I'm still moving forward on slowly  ::) with my build . After stripping the second F1 motor I've decided to base my build on that motor . Even though it has obviously been standing for years, and it's mileage etc is unknown to me , it is in very good condition internally .
I've had the crankcases vapour blasted , and have removed all the oil way plugs for cleaning and started on re- tapping all the threads etc , in preparation for the H/D crank & head studs .
I'm going for 1060 , so need to find a shop/individual who can do whatever is needed to fit and bore out the liners and bore the top c/case to fit .
The gears, selector forks etc are  in fantastic condition so I'm just going to fit  new bearings and  the undercut gears which cycle X recommend.
I plan on fitting one of cycleX's lock up clutches , as well as their primary and camchain tensioners . I have one of voxonda's kits to uprate the primary drive sprocket shock absorber .
I may go with new stock primary chains , but check them regularly .
Meantime the search goes on for a good stock motor to get us up and running this year .


Work in progress .

Keep in mind Goldenrods are billet, not forged..like most other aluminum rods they made for our bikes.

It's a bit milder here at the moment . So today I spent the afternoon running a tap through every thread on the c/cases , and de-burring the cases internally , in readyness for cleaning and also fitting the uprated studs. I also had a go at removing the sludge trap balls and fitting grub screws on a scrap crank,  for when I do it on my good crank.
Frank , I hear what you're saying about Golden Rods . I'm currently on the lookout  for a suitable set of rods . CycleX and APE are currenly doing sets of uprated( but heavy) budget steel rods, which look very interesting . If I cant find a set of suitable rods at the right price, I may bite the bullet and purchase a set of Carrillo rods .

I must say your bike s looking good Greg 8)    dont stress about time, seems most people take around 3 years on a serious project like yours, with family, life and bank managers interrupting a perfectly good day in the shed.

Dont forget to use a brush of some description in every single hole while cleaning the cases,  I found evan strong detergents and pressure cleaners dont float the glass off in tight spots, just needs a tickle to get it shifting.

Now your getting into the nitty gritty of the engine Greg, more close up shots so we can see how clean things are ;) ;D

Thanks for the words of encouragement johno ;) . I've gained a lot of inspiration off your excellent build thread , and am trying my best to emulate your very high standards . I got a set of  brushes a while back , and I have all the other necessary paraphernalia to ensure that  I have the right tools for when I get started on the big clean up  .
I sometimes work long hours and occasionally am away for a few days at a time , so working on the bike usually has to wait till the weekends . As well as being my current hobby , working on the bike is also good therapy.
My motor won't be anything special ,as it's all been done before .However, I will endeavour to record the build with some decent close up shots . Greg "H"

While the search for a suitable stock motor has(up till now) proved surprisingly fruitless   , I have been busy getting things organised , and have managed to pick up a few nice bits for the race motor along the way.
One of the things I've managed to pick up is a set of big bore (71mm) liners , and now all I need to do is find a suitable set of high comp pistons to go in them .
The search goes on for a good stock motor for this season.
I also picked up these old mags a while back ,that I'm sure a few of you would have read back in the day  ;D ;D.

Hello there SBR-CB400F :)
I've managed to collect a few nice pieces for my Hipo motor , but unfortunately haven't been able to find a good stock motor yet to use for the time being :(.
I'm just trying to stay positive ,so I've renewed my race club memberships , and will be renewing my race licence in the next couple of weeks , cos the 2015 race season is underway now.
If I can get lucky on the motor front, I'll then be in a good position to get a bit of racing in this year : 
If it doesn't work out I suppose I'll just have to get my speed fix spectating, and  chatting to the guys at the meetings .If thats how it works out  I'll just have to get my finger out, and get the Hipo motor built asap .
Regarding the Big Bike mags . I used to have quit a few back in the day,along with many other American Hipo bike and car mags . Unfortunately they all ended up going to the local tip when I got married . So now I try and pick them up off fleabay when I can .

I spoke to the top man from D&K Motorcycles (who are the UKs and maybe even the biggest bike breakers in Europe) about them selling me a good stock motor, and also about me being able to hear it running first . He seemed intersted in what I'm doing and made the right noises regarding selling me a suitable motor straight  out of a bike .
On the Hipo motor front , things are moving ahead slowly .In the meantime I've been keeping myself busy doing a couple of little jobs on the rolling chassis , such as raising the front tank mounts so that now there's more room for a tank vent under the dummy tank. And curing a slight flued leak on the front m/cylinder.  I've finally found a guy to do the big bore job , and I will be taking the pistons/liners and c/case over to his (he's approx 40miles from me) at the end of the week .
I now need to sort out a suitable set of rods so that I can get started on building up the bottom end .

A pic of the piston kit ready for taking to guy ,and a pic of the raised tank mounts.

I need to be making these small steps forward to keep myself motivated Bill ;D ;D .
It's going to be very interesting when it comes time to work out what this bike has cost me . I've kept every reciept , but have resisted working it out so far  ::) .
So far it hasn't cost me more than I anticipated , but I have to say ,that the poor exchange rate and the duties I've had to pay for some of the stuff I've had from the US would probably be a deal breaker if I wasn't so commited to finishing the job .

Very true Bill .
I'll have to get this build right cos if it goes bang I won't be building another  sohc 750 based performance motor .
I know to some it will be considered to be sacrilegious but I have been giving some thought to shoe- horning a non sohc Honda aircooled motor into this rolling chassis if this motor goes tits up . ;D ;D

wish you were on this side of the pond ,you can get engines very cheap,I guess you have to do what you have to do when and if the sohc does not work out,but I think it will eventually.bill
