hmm no wonder i cant get the rear to move the standard Honda spring is 950lb/in [or 170kg/mm]

and ive got two !!! :eek:

have you got clear shots of the front uprights? im thinking of using my old omega

Erm yeah i have it wasnt easy required alot of chopping ill see when i get home if i can find a pic

That's why they use R6 instead of R1 shocks....

Ive used honda firestorms on the rear hence it not moving as it has two 950 lb springs the r1 shocks on the front are not really man enough ill chuck another piccy up but all that will need changing is the springs

And they didnt have any r6 in the yard and rears needed to be slightly longer than std spec due to my rear end setup

theres almost no info on the web i can find reguarding the spring rates of the yamaha shocks


rang yamaha today and i think i wrote them down wrong

r1 7.84 n/mm

r6 95.10 n/mm

there seems to big of a distance between them i think i made a boo boo !

research is hard when cradling a 7 week old or busy at work :D

Thanks for the input Rob... certainly food for thought huh!

yeah plenty for me to go at going to make them work now even if it means minor chassis mod :-)

heres how its currently sitting





as i mentioned its sagging alot but i think it also has something to do with the tyre profile think they are a 205 60 / 65 15 profile i have the choice of modding the bottom mount or top mount on the chassis not sure which would be best or i also had the idea of making a ride height adjuster style thingy ma bob in place of one of the above similar to the classic mini setup ?? just batting an idea about ?

i will have to buy new springs but the whole lot will come in at under half the £400 for gaz shocks

mmm ive been out again ................ how much travel does the rear suspension need ? roughly ?

I'm going to use Yamaha R6 shocks. I bought them on ebay for less than $200 US. The spring rate on them is around 500 lbs. Plan is to mount them inboard with rockers so that I can change the leverage to compensate for the spring rate.
