spring rate ?

[32:1]

Hi Guys

After too many years off a dirtbike, I've just got a 2006 ec200 to trail ride and the odd enduro.

Its a mega little bike after a touch of TLC

One issue I have is the suspension being to soft, it has 45mm shiver forks which are real plush, and an Ohlins shock. Im 17.5 stone so I need stronger springs no doubt, can some kind gent advise on correct spring rates for it.

It really gets unsettled in fast bumpy sections, as well as bottoming in G'outs and landings.

Any help would be cool....

Regards

Guessing you are in the UK. motopsycho may be able to help: http://www.gasgasrider.org/forum/showthread.php?t=18004

Gas Gas UK do not stock springs for the ohlins shock. I've been waiting for nearly a month now for the spring I ordered from the British ohlins importer. They did of course take my money the moment I ordered and their customer service is sh1te, so avoid if possible.

Ive heard much the same about them and Im still waiting for them to get back to me for three weeks

I bought this gasgas to get back into a bit of off road riding. TBH its proven a bit of a bad apple as I cant find info or get advice from anyone. It was for sale with a TM EN125 and Im wishing I took the TM right now.

I have a plan to change the front end to a exc WP setup as parts and info are easy.

Ive got it going well now, new piston and modded head and fitted a DEP exhaust. The motor now pulls strong from off idle and has a decent overrrev too, shame I cant get the thing to handle, its like a 1970's mx bike, horrible

Biketech is worth a go for GG parts - he allegedly keeps more stock than GGUK and has a lot of experience regarding riding and working on GG bikes, old school to deal with, only phone and don't bother emailing. Steve Plain is good too, and sometimes has reasonably priced goodies like decent second hand wheels from the race team.

I would give the WP forks a miss - KYB conversion probably better if that's the road you want to go down (there's some KYB conversion threads on here), although it might be worth setting up the Marzocchis right - they are sprung for an 80kg rider from the factory, so will be miles out if still standard.

Does anyone know what the standard spring rate for 32:1's bike is?

I weight 95kg (210lbs) and have a 6.2 on the rear, I haven't checked the front but it feels equally firm.

How are people getting results for the mid 2000 bikes on the racetech calculator? It only lists 1999 and 2000 250 / 300?

I'm 101kg and the ohlins importer said 5.8 is correct for me, so 6.2 might be out of range. As I understand, the ohlins shocks, although outwardly similar, are not all the same. In our case, the GGxxxxxx number stamped on top of the shock is what ohlins work from and the spring is specific to.

Thanks for the link for marzocchi springs. Marzocchi corporate representation in the UK seems to consist of a mountain bike shop and they did not sell parts at all, although I managed to get Marzocchi branded fork bushings no worries from Steve Plain (oil and wiper seals are common metric size, so get them anywhere). When / if the ohlins spring ever turns up, I'll see how the sag is looking and whether the forks want heavier springs too. I expect it will be possible to work backwards from the current sag measurements and make an educated guess about fork spring weights if the information is not openly available.

I rode a buddies exc250 2006 that has just had some TLC from a suspension co' called Tillet. This bike was like a hovercraft, Ive not ridden anything the controlled for years, on some sections where I was bucked and kicked so bad, could then be ridden one handed clearing goggles on his exc..

RESULT
Called Steve Plain and they took info and called back within the hour with specs and prices. Shock spring had to be ordered but at least Ive got it sorted out, even bought other parts from them too..

Any Gasgas owners need parts / advice give them a call

What did he recommend and prices?

Tried the racetech suspension guide and it seems to think 4.6 - 4.8 on the front and 5.8 on the rear

That's the issue I have, there's just no info on these gasgas machines ?

I will check those two leads out tomorrow, thank you..

And I will forward my spring rates to you moto/
