Bar End Weights

[sadlonelygit]

The fork springs are K Tech linear 95Kg.

there's your problem.........should be 0.95kg/mm :rollin
that sounds ball park (plush) for your GVM. you have to remember to use alot more rebound with firmer springs.........because they're firmer and rebound more! and a bit less compression. get the sag set next then you can start fiddling with damping settings.
a nice new notebook might be in order as well, to jot down all your settings and what you think.

I see your point on me missing my point

Hey bear, i can see how all of the individual problems are making you think but without knowing the bikes history they could all be totally innocent


For instance-the front tyre wearing on one side, was this the right hand side???,if so then did the previous owner merely do the same journey every day in a big town or city with lots of roundabouts,we are creatures of habit,you go to a new town like milton keynes or glenrothes & all there is is roundabouts.


I really think getting another foccer insured for the day on your bike would be worth its weight in gold, im sure the mechanic has a good idea by the sounds of things but then had he just come off a repsol honda or some other dream machine,even still im sure he knows his stuff but someone else that rides a gen 1 every day will know far more i reckon,equally you could try blag a ride on another gen 1 to check the difference.

Wheel bearings are normally removed and replaced with new when powder coating (or at least they are in MY shop when we do them....) as the wheels are subjected to quite a lot of heat the fix the powder coating and this will not help the bearings one little bit.

I am happy the jack up kit is coming off, if you had the Nitron built for your weight, the "correct" spring will hold the bike at the proper ride height and remove the usual need for a jack up which is to support the saggy arse of the bike which the bike gets with the standard puny spring.

The shock AND the jack up kit will have the back end a tad high and cause her to steer quite quickly - maybe too quickly.

yup both times i had wheels powdercoated i removed and replaced the bearings. the heat they would be subjected to would not only possably warp them but the grease would drip out and screw the powdercoating up i would think.

i replaced my rear with a nitron and loved it, i also run a jack up kit but when i fitted the jack up i had to take about 5 rings of preload of and play alot with the damping to find an aceptable feel. still not as good as it was before i fitted the jack up kit but at least my hips dont hurt now.
i also have a full Ktec front for rework. not sure off hand what springs they fitted off hand as its all in the papperwork though. i also dropped the forks 10mm.

so reowrked front forks by ktec
10 mm lower on front
nitron rear shock set up for no jack up kit but altered by me..... badly
jack up kit on rear
flat bars
ps3's fitted front and back running at 3-4psi under recomended on front and recomended on rear

i find the bike a little unstable at very tight low speed turns like jcts. the bike just falls away
but on the road with roundabouts and bends its rock steady. quicker steering than before by a long way but still stable.

Get the bike back this afternoon.....bent dog bones on the jack up kit looks to be a contibuting factor, now back on standard. Frame, forks, wheel alignment all checked out ok. We are going to some testing over the next week or two and adjustments made to suit.

Watch this space

[ghostbiker]

Hope it was as simple as that. Have fun testing

[AyJay]

Jeez. How would someone bend a dog bone? The previous owner must have been a gorilla. Or an elephant. Or maybe he was riding motocross on it. Hope it turns out ok and glad the alignments all checked out for you! Nothing like knowing you've got a straight bike...

[nickodemon]

I think that once you have replaced the dog bones it will make a huge difference. I also think that the nitrons are possibly slightly longer than the standard shock to improve handling, so if you fitted the nitron with a jack up kit the bike would feel really twitchy and would fall too easily into corners and weave in a straight line. If you try it once you put standard dogbones and it doesn't fix it i will take a look at it for you, as i am in Glasgow. I have owned 3 gen 1's over the last 8 years, so have a good idea how it should behave. I also know the boys from dynotech as i had my zx636b1h set up on there dyno years ago. Let me know how you get on. Cheers, Nick.

So far so good, took a detour on the way home from the garage last night and very a noticeable difference for the better. Going out on my TT course this morning which has a combination of more or less everything to give it a right good test.....sun is shining, roads are dry and have a full tank.

Dont you jus love it when a plan comes together!!!! 8) 8) 8)


Foc-u rules!!!

My usual TT course is A77 to Fenwick to Kilmaurs to Stewarton to Neilston to Barrhead to Lugton to Dunlop to Stewarton then Stewarton Rd back to the Mearns, 50 miles in total.

This time I went a bit further and went straight through Lugton to Ardrossan and on to Largs, 120 miles in total

Results time.........effin awesome, its like a new bike and is running and riding as I knew it could. 

You are right on the Nitron Shock, it is longer than standard and with the jack up kit on it was way too high at the back end making it steer in way too quickly for my liking.

Thanks for all you Foccers advice, its totally transformed the bike 

[nickodemon]

Glad you got it sorted   I sometimes go the route you are talking about, but when setting suspension  i always use the eaglesham moors road, as there are several high speed dips, which is great for setting the compression and rebound damping. Enjoy your summer riding
