Re: Hot cams on ebay
soz kev, sort of cross threaded a bit lol - i was looking at intech vacuum control valves but cba spending 200 notes on something that may or may not work, so i got some from flowtech instead - i'll post the part number if i can find the bags or my catalogue.
basically the idea is, the inlet vacuum is approx 20mm.hg, but when you throttle off in a corner and get the BORrrrrrrrrrrrrrrrrrr sound and the rear wheel hops, the vacuum is massive.
so with these things set at maximum, they will allow a vacuum of 300mbar and then open a port to allow air in, to control the vacuum at 300mbar, but not low enough to interfere with the operation of the slides.
i'm still trialing it atm but seems to do what i want... the engine braking is still there, but nowhere near as severe, meaning i can more or less coast with the throttle off.
if i decide i like it and the plugs dont go white, then i'll mount them inside the airbox, under the filter, with just the inlet hosetail sticking out, where my carb balancing lines plug in.
they were £22.50 each and i get 50% off, so just 22.50 for the 2 - better than 200 lol, seeing as i wouldve needed one for each pot that wouldve been errr lots of wasted dosh.
have a look at the intech thread.
i'll update it with pics of the finished job if i think it's worth doing.
anyway - cams
i've been busy!
check out the profiles -
new exhaust vs old
much sharper profile should snap open & shut, with higher lift
inlet - higher lift again with a longer open period - get more in lol
billet steel vs cast oem cams hope theyre fkin hardened proper
nearly forgot to knock the core plugs in lol - these are fkin mint, never used lol
got them in but decided to have a break then go back & check what i've done.
they'll probably want shimming but i miked the journals and they were same as stock - i'll get the feelers on them tomorrow probably or later if i cba lol.
can't wait to redline it with these babehs in

Re: Hot cams on ebay
i can't leave crouton all alone lol - everything i get i have to meddle with
keep looking at my old cb thinking about streetfightering it... is bloody nippy for a old 750 but i feel sorry for it every time i go in the garage - it's just a refuge for homeless spiders atm & somewhere to hang my leathers when theyre wet!
was a good bike in it's time

Re: Hot cams on ebay
It'll do you a turn while you're looking for another engine on E-Bay, though.
Have you checked that the coils don't fully bind on full compression from the lobes?

dont think so tho cos it turns nice and no crunching.
id expect it to lock up if it was bottoming out the coils....
just a bit wary of my measurements on the valve clearances as they seem ok but maybe a tad tight at 15 & 30 thou??
hoping to run it tonight but im shattered tbh after a late one last night and being stuck in traffic half the day!

Re: Hot cams on ebay
just as well i didnt lol...... checked clearances again, front inlets 15 thou, rear inlets 16 thou, happy with that..tony.mon wrote:Stop bottling it and press the button.....
front exhaust rt side 31 left 16, rear rt 12, rear left 8
they should be 16 thou inlet & 30 exhaust +- a few thou...
i reckon i will be on the edge with cooling so i'd rather run on the slack side, and maybe fit a fan on the left?
if anyone's got a spare fan assy, let me know pls!!
best get on flea bay now & see if i can find a shim kit - i'd rather get it right...
just out of curiosity, i rested one of the old exhaust cams on the head and it measured the same... so either someone's fkt up bigtime in the past or i've got some problems with my eyes!
it's a wonder the seats havent burnt tbh...
*anyone spot what i did wrong there????

Re: Hot cams on ebay
Or fit a bigger oil cooler, achieves much the same thing.benny hedges wrote: i reckon i will be on the edge with cooling so i'd rather run on the slack side, and maybe fit a fan on the left?

I'm planning both, fitting a manual fan on the LH radiator, and sorting out a bigger oil cooler and lines- not sure where from yet.
Gotta be a race one available somewhere.

Re: Hot cams on ebay
measured up the oil cooler on my 750 a while ago looks like i can make it fit...
another simple option is piggy back a 2nd oil cooler on top with the bracket the other way and use compression tees on the pipework so they work in parallel?
still want a left fan tho.
bloody shim kits lol - £3.00 for a single shim or 70 odd for a kit
had to be done unfortunately, can't start it up knowing it's not right - you know what will happen lol
*btw....
mail from the guy i bought the cams off.....
i asked him for the manufacturer details for the timing info....
Hi Martin, I was told they are HRC from a Belgium
source They came from wsb test team mechanic about 5
yrs ago Thanks Rob

...........................
ordered some uprated springs as well from tst....
and in the meantime, i'll fit these
cant believe how light they are! including link pipes the whole package was under 4kg!
