Ok,the form is in,I've asked to be put in the firing up hall as we normally do.
in that case , I might be persuaded to bring the stocker (and its starter....)

I'd like to see some of these 'mythical' higher ratio gears? Its just that for the 40 odd years that drag racers have been abusing these engines with just about every modification anyone could think of, no one nor none of the specialist aftermarket vendors bothered with having hi ratio gears made . . . . . Even Chris Hannam, owner of Cannon Engineering, who were gear cutters to industry and beyond, never considered making them and cornering the global market!
I had a set of these higher ratio gears made by Chris Hannon (yes , he did make some a good few years ago)........had a small quality issue with them , so decided to get my own made !

my thoughts are - when I see a 6 second turbo funnybike with a bandit motor , I'll believe they are a stronger engine.....
Welded crank and straightcuts - both essentials , but chuck in a heavy duty backplate for insurance
a full set of top and bottom end heavy duty studs will hold it all together
as far as I know , there are no stronger rods available - katana rods are said to be the best , but finding a new set today could be a struggle
over-revving is what kills cranks - so a shift light / rev limiter is a good idea , as well as a thorough inspection of the whole gearbox and shift mechanism
also - sort the oil pickup so it takes its oil from the rear of the engine - stock only works well when slowing down....
acual power level will then depend on capacity and boost - but north of 250 should be easy and reliable

I have been looking into getting new ones made - there seems to be a world-wide demand !
Tricky part is going to be the retaining plates - moulded in on the originals (and not very well at that) but I have ideas......

These are the things I'm not sure of, I put some tape on the disc and marked out the brake pad where it would sit and it looked to be on all of the disc! maybe I better take a closer look, as you said, it shouldn't line up with one bolt in the original fork, (I would sooner buy a set of plates made up, But I am too far from any engineers, I also have a rear caliper that needs a bracket but that is well beyond me,
They seem to be, I ground an angle on the plate so it would sit tighter and flater to the main fork leg,
my original calipers have broken nipples, stripped threads, and seized a bit etc,
my method to check position is to bend a piece of 2.4mm ally filler rod to the same radius as the disc , tape it to the disc - and put the calliper in place , making sure it is sitting on the welding rod at both ends - then rotate it till it is near the fork leg , and see where it wants to sit

hate to be `that guy' but it doesn't look to me that the calliper is sitting correctly on the disc - since that calliper is for a much larger disc , its more than a bit unlikely that one of the mounting bolts will line up with the mounts on your forks - I have made more than a few calliper adapter plates , and they have never lined up like that..... I bet the `front' of the disc pad is hanging off the edge of the disc.......

Melbourne went better than expected , with another good performance - low ET , top MPH , number 1 qualifier , and win ! I seen to have got my act together this year , trick seems to be go as quick as I need to , and dont waste effort trying to go quicker all the time.
Finished the year at Santa Pod last weekend , and was on for another win - until crew shortage and an organisational cockup left me using a borrowed starter for the semi final.....and it failed.....so ddint get to progress to the final (had a good few tenths in hand for that race...)
But , despite the failure , I only went and won the Old School Stockers championship for a third time - I got the Straightliners championship as well !
YAY....go me ?
Also had a good day out at Stafford classic bike show with the OSS crew

check for shims between the clutch center and basket - sounds like tightening the clutch hub nut it is pressing the inner and outer cutch baskets together - had this on my GSX when I accidentally put the wrong clutch bearing inner spacer in , not realizing I had 2 different ones , wrong one being .5mm too thin......

Looks Like an EFE Swinger to me which you can get a 5.5" wheel in
I realy should pay attention when reading threads......yep , mine is an EFE.......I'll go stand in the corner right now

if you are using the OEM swinger then you will only get the B6 wheel in with a 150 tyre, the B12 wheel/tyre is too wide. you will need to use a bandit calliper hanger so it matches the bandit disc, but because the torque arm is on top you will need a GS 500 calliper as they are top mounted.
I run a 170 on a 600 SRAD wheel in the stock arm - with a 170 tyre......its piggin' close with a new chain , but OK once its done a few hundred miles

More to add......took a trip up to Melbourne Raceway at the weekend , to see what I could do on an un-prepped track - and there was some sideways wiggly fun to be sure .
Managed to find a reasonable setup , and ran down to a 5.9 best , with a couple of 6.0's - then won the old school stockers eliminations , so more trophies to dust
Thanks have to go to Bow Trowel for helping with crew duties - next time out is Santa Pod for the last race of the year in October - better dig out them thermals and my umbrella !

its been a while.....a lot of racing has happened since I was last here , but every time I tried to visit this site my computer said no.....
Dragstalgia 2019 was just the start - from there , I got my `race head' on , and have been number 1 or 2 qualifier at every race - and win or runner up - resulting in 2 old school stockers championships , and a good chance of making it 3 this year .
This year has been amazing , with taking number 1 qually , low ET and high MPH , and win - at every race I have done , new PB of 8.44 and best speed of 155mph !
Super consistent as well - Retro show was 4 runs on the Sunday as saturday was a washout , all within 4 hundredths of a second - 8.44 to 8.48 , 60 ft down to 1.20 , 5.30 in the 1/8th - all from a motor that the head has only been off once to check , and found the pistons were `just' touching the head ! extra 10thou of base gasket , along with another 10thou off the head sorted that , although it did have a healthy appetite for gearbox's , now cured with a horribly expensive billet 5 speed auto box
And finally - a new (to me....) race van , big enough to take the road going EFE on a recent trip to the Isle of Man , and a built-in proper bed !
Might have to find some more power for next year if I want to keep this up - and oh boy do I !

Oh - and I'm also 2 times old school stockers champion , close to making it 3 in a row this year !

Not been on here for piggin ages ! for some reason computer said no when I tried.........
Anyhoo........much progress has been made on the EFE , had too much trouble with stock box's so in went a full billet 5 speed auto....and a change of wheels along with a splash of paint !
The end result has been pretty stunning - at Retro show , it ran a string of 8.4's at over 150 , resulting on low ET , High MPH , number 1 qualifier - and win ! Then managed a repeat performance at Dragstalgia (but around a tenth slower due to the heat)
Then - Jurby , Isle of Man just for fun - and another repeat , with a best of 9.07 @ 155......
Out at Melbourne this weekend to see if I have found a good dodgy track setup

You managed to fill the oil holes on an angle in the heads?
yep - easy to do

Care to enlighten us as I've never heard of anyone using anything other than 750 gears even PS engines? Restriction to cam bearings seems daft - saving a cam or rocker at expense of destroying a fully worked cylinder head - bizarre!
I had a bunch of gears made that are 11% higher ratio than normal 750 gears - I run 750 primary gears , so using the normal setup would leave me stock oil flow.......
I've never had any cam bearing problems , but over the years a lot of burned rockers and cam lobes - very high lift cams and high seat pressures with ovesize stainless valves

The oil still get there via the head into the stud bores.
Not on my engines - I plug the oilways in the top case , and the heads , so no pressure on the head gasket - I also run larger bore oil hoses direct from the ends of the oil gallery to the head , higher ratio (than 750 gears) pump gears , restricters on the cam bearing oil feeds - all to get maximum oil flow to the rockers and help my cams to live........

A major benefit of using a top end oiler kit is , if done properly then oil leaks from the head gasket will be pretty much non existent - as in , you need to block off the oilways in the top case and the feed holes in the head , so all the oil comes in from the top end oiler hoses .
And definately fit some high output pump gears - I use some that give a 40% increase , along with a large-bore top end oiler kit , and have no problems running up to 12000rpm with big cams and suitably heavy valve springs .

well.....after a cracking race day yesterday , despite losing in the final to very rapid and consistent Kevin Melling (well done Kev and team for some outstanding 8.5 second runs !) the news is in , the points have been added up - and I finally have a number 1 plate for the race bike - thankyou to all that made this year more than a bit memorable - Alan Ward and Harry Barlow for some top crew work , Tyne Blight for getting the whole Nostalgia Pro Stock Bike off the ground , and all the competitors for just being there and helping make this all possible , as well as the race organizers for putting up with us
Oh and anyone else who I didnt mention , thanks for helping out when possible !

530 weigh a lot less than a 630, unsprung weight is better
another of those wonderful chain myths.........while each individual link is a tiny bit lighter , you are gonna fit sprockets with more teeth , and will need more links of the smaller chain to cover the same length........so if someone can tell me where the weight saving comes from , go ahead punk - make my day
(106 link 630 , is the same length as 127 links of 530.......and to keep some swingarm clearance 15/42 will normally be swapped for 17/48)

EFE valve guide question
in Air Cooled
Posted
Just found some cheap Hyabusa Titanium valves on Eblag - and wondering what , if any , guides I can buy to fit them into an EFE head ?
Would busa / GSXE gudes fit - or am I gonna be looking for something `special' (as in expensive....)
I know they will need shortening , and the inlets turning down a bit - but neither of those is a problem
