fzr 600 foxeye (4jh) rear suspension trouble

[duzzer]

hi every one, i just recently required a fzr 600r genesis on a 95 plate and am having trouble finding a replacement rear suspension.
the one that on the bike now has seem to of sized solid and wont budge even with 3 people on the back its got like 5ml travel so i was after a after market one but cant find any and the original one is around 300,

is there any other suspension from another bike that will fit or any where that has after market shock

thanks

possibly thundercats? fzr1000? tried all the different years?

600 Fazer shock might be worth looking into. Youn sure it's the shock that's seized and not the linkages?

Hi

I would agree with Vincent to check it isn't the linkage instead of the shock.

Thundercat shock is probably the most likely to work OK as mechanically it is stuck a similar bike.

All the best

thanks for the reply guys,

iv been digging in the fzr rear shocker this morning, and yes it dose seems that the fzr 600 (94-99) and the yzf thunder cat share a very similar link design so just may be one will fit,

no i haven't check the link to see if there sized (i dint think thay can?) but i will be checking tomorrow, if that fails, am considering removing the spring and refitting just the damper with out the spring to se if i can un-seze it that way

wish me luck

Hi

Linkage is far more likely to seize than the damper itself.

I have had a damper seize one but it is a rarity. Place that rebuilt it was somewhat surprised. What seemed to have happened is the rings on the piston in the damper had worn enough to come out of the grooves and jam between the piston and the body of the damper. The shock was pretty much scrap.

All the best

had the bike frame out to day, had a look at the links and damper, links ar fine but the rocker and the rubber brushes ar corroded, same with the shocker,, cording brushes top n bottom,

also good news the fzr 600 4jh foxeye dose shere the same back spring as the yzf 1000 thunder race and there one for sale with in 5mile from me, thay also have the rocker

BUT,,,,, the last mechanic who fitted the rear shocker did not grees the bolts for the shoker n rocker so even with the nuts off the bolts wont bugge as thay have crodid inside over the years, iv used wd40 and foul language and its still not coming, any ideas

thanks duz

Hi

Leave it soaking to ages in something that will free it off to an extent (bucket of diesel maybe). Likely won't fix it but should help.

After that use a press (or if you can't get access to one use a large vice carefully) to try and push the bolt out.

Bolt will have seized to the bush, so it all else fails chop the bolt as close to the bush as possible (ie, flush with the end of the bush), as then the linkages should just come apart. Then replace both the bolt and the bush.

All the best
