Topic: Lifting the rear end?

[zzcoopzz]

Any one know what it would do to the handling of my 77 CB750F if I were to raise the rear end by about two inches?

It will alter the front steering geometry a little but unless you're a dedicated racer you are unlikely to notice the difference.

I have  done thate on my CB750K7 ,it felt more like "new"bike and it lookt like it to !

[zzcoopzz]

how did you get the rise. I was just thinking about making a sturdy riser and attaching it to were the shock meets the swing arm.  however there are probably attachments already fashioned that are much more safe them what I could make.

I replase my rear shock absorber (Suspension) get a Koni  pair from a CB900  a litel bite longer   (79mod)

You have to have a reasonably good reason to elevate the frame from the rear wheel.
Yes, the geometry will shift the rake of the front wheel assy usually to make the steering more sharp but can be a little unpredictable under brakes in a corner.
I did this virtually unwittingly by getting a pair of KONIS and rebuilding them like new BUT the series was wrong for my CB 750K5.
I should have placed Konis 7610-1296s on the beast but placed -1314 on the bike.
Rides wel with two up, but It will not sit well with the center-stand in position. Mostly the rear wheel will sit on the ground. Also the bike will lay over at a terrible angle No good for carby bikes. Also the chain when slightly loose will grind through the centerstand webpads, giving the bike a terrible vibration, usuallu i think of the worst thing available but its the chain on the legs of the part which touches the ground first. 
Too high.Stick to the normal shocks and use a high profile tire if it's too low.

It would make geting your leg over that bit harder

[oldbiker]

I always find it hard to get my leg over!!!

Sorry  foks , but   it`s works for me.
If sombody want`s to may put a mono shock  let them do it.
Back in time Colin Seeley`s had various of kits  on thise kind of bike!

Well if you are over 6'3" then I suppose you could do a rise but my 78K is high enough that at my 6' height, I can barely put both feet flat on the ground.

[Egil]

I have this height, I am in Nearly 201 Centimeter and have no problem to put bouht feet on the ground

To balance  my bike I put Fork fro CB750/900 F/F2 and at rear I put standar CB900F /Bol`dor 1979 mod

Hard to say but I suppose bikes from different countries could have different heights. Mine sits very high. No lifting for me!

[Egil]

You now I do have a litle bitt bigger rear wheel in sted of 4,50Hx17A ,
 to  (3,50Hx18)I have 120/90 x18 VR
 and I have raist my front so muts as posible,
Is it normaly to having  som woobling in searten speed from the front wheel ?

usually there should be no wobble. That is usually cause by a poorly worn tire, bent rim, wheel out of balance, or bearing problem. If it is at certain speeds then I would have to say it is a balance thing or bent rim.

[Egil]

I have bearing problem on(in) the wheel!

Return to  heights of the bike  MY bike is up to the topp in front of the sadel white me on ME siting as I us to do .
From earth to front of sadel  it is 33inch( 84,8 cm ) From earth to lowest poin of fot pegs (30 cm)

I hope this  is better  to  understand  !

zzcoopzz : You have an CB750 F version            I talk about a sertains diffrent  , if you go in on thise ar det diffrent between 2 version`s.
