    Camshafts and timing and stuff

    Big cams always come with large overlap numbers which is not what turbos want. No point making boost and blowing it straight out of the exhaust!

    2 valve heads have more lift then 4 valve heads?

     

    With high lift automaticly comes more overlap? I guess?

     

    Just thinking, sse a lot of modern bikes with turbos, more modern bikes have more lift and overlap then the oldies..

    Gents,

     

    One hand just curious, other hand, what if?

    I've got an Suzuki GS1000, 1245cc big bore, 119grind Webcams +1mm lift, 2 valve, cr 8:1, 15 psi boost

     

    I've got a set of high performance cams, that much lift that the head needed to be modified, IIRC 284 degrees timing. These cams make the bike slower with stock pistons.

     

    These cams, is that a no go already? Or would they have a positive result? Say, would they be beneficiary with my set up? Is it possible to change the timing so they have a positive result?

    I assume that when you add lift, you change the timing?

     

     

    Thanks for any information :)

     

     

    2002 GSXR1000 rear shock spring rates

    Gents,

     

    I've got a Frankenstein bike.

    GS1000 with a Bandit 1200 swing arm incl. linkage. I bought a 2002 GSXR1000 rear shock for it.

    Rear suspension travel is 13cm, when I sit on it it drops about 6cm, with the spring set it it's tightest.  Now I need a stiffer spring.

     

    Does anyone know what the sprin rate is for the stock spring? I've read somewhere it's 77N/mm, no clue if this is right.

    I weigh about 96kg, should one step up be ok?

     

    Thanks

    Gasket sealant or not?

    I'm replacing the head gasket on my EFE with a fibre one. I have the factory manual but it doesn't mention their usage. I think they had MLS gaskets anyways. So my question is should I use a sealing compound with the fibre gasket or not?

    Thanks, Jonny

    No

    Does it has enough travel?

     

    I just bought a Brembo clutch master, the Nissin had a 14mm piston, the Brembo has 13..

    My clutch hardly works, after some detective work I found out that the Brembo has about 10mm less travel on the piston, therefore I need to build a slave cylinder with a smaller diameter.

     

    You need a minimum of 3mm travel on the pressure plate of the clutch, to disengage it properly.

    So, the content of the clutch master (surface area X travel) need to be the same as the slave cylinder (surface area X travel)

     

    I can do some calculations for you, but I need details from you;

    Diameter piston old pump + travel

    Diameter new pump + travel

    Flat side carbs vs Diaphragm

    I had Mikuni RS34's on my bike, I  didn't notice any gains in power, it just had an incredible throttle response...

    Probably more torque in the lower revs... Did I already mention it gave an increadible throttle response?

    It is a bit but you get comp and rebound damping as well as fully adjustable preload 

    I’m 18 atone and needed a slightly stiffer spring to get 25 mm of sag:tu:tu

    Thanks.

    I bought it because it's fully adjustable. Of to work to make some dogbones. I'll see today how it goes / what it does..

    Yes,:tu

    is it a Mark 1 or mark 2 bandit shock as they are differnat lengths.:)

     

    Ive used K7/8 1000 shocks on abouit 12 or more of the B12's ive owned all mark 1's.. my shiny heron one has one on with a stiffer spring for the larger gentelman:$

    Thanks.

    98 Bandit. I already started...

     

    Is the GSXR spring much stiffer then the Bandit one?

    Gents,

     

    15 years ago I modified my GS1000, I made a swingarm in it from a Bandit, made it monoshock with the Bandit shock.

     

    Lately I'm trying to improve the suspension.

    I ordered a rear shock from a GSXR because it's fully adjustable, but apparently I didn't look properly, t doesn't fit...

    I can make it fit, but that involves a lot of work. Move the battery and ignition module..

     

    My question, is it worth to make the shock fit? Is it much better then the Bandit shock?

     

    Thanks

    just seen these on Eblag thats why i asked       Eblag item number 165608687054  he says there of a gs750 but will fit many other models 550 650 850 & 1000

    but im not sure thats why im asking the experts here

    H

    That they fit won't say it will run properly.

    My bike (1250cc) didn't want to run properly on GSX750 carburfuckingettors, had to buy a set of a 1100

    I've got a 493 rod lying around I think, which dimensions you want to know.

    When you buy them, the Suzuki dealer is probably the cheapest way to go, be aware that you get the same color codes, different colors is different weights

    Something weird with my throttlebodies

    I'm not gonna rule out the possibility but to be honest this feels like a mechanical issue. Like if you manage to turn the adjuster to find that "sweetspot" it'll happily sit at 1000-1100 rpms all day until you touch the throttle. Give it a rev and it might settle down again but most times it'll hang at 1600 or 1900 or somewhere in the region. Sometimes it'll sit there for a little while and then come down. It's like the return spring is too weak or there's just some crud or other shit preventing it from closing those last few mikrometers... 

    No vacuum leaks?

    Engine tuned correctly?

    Depends on your callipers. 

    Radial m/c have longer levers because they moved the pivot point over. To get the same displacement the piston size goes up.

    Aha, thanks.

    I already thought it had to do with different amounts of travel.

    Seen more then a pair of Beringers with faded colors so choose wisely. And you probably know this but still, radials need a bigger bore then axial m/c.

    Do you know how much bigger the diameter needs to be when go radial?

    Bigger bore for radials I did not know.

    But I ordered axial ones.
