FMX 650 Tuning

[mergoofmx]

Hello,


I have a FMX 650 which is pretty slow as std. i have a set of arrow cans on my wish list and i have ordered a ABP header and mikuni flatslide card and pump from germany.
Does anyone know of any "quick tunes" to get it going a bit before they come??
any help is appreciated.
cheers and happy riding

You could get different sprockets...

Bigger rear gives faster acceleration / more wheelies, tradeoff is less top speed.

Open cans and headers and a well-jetted flatslide carb is the proper way to do things though, keep us posted on how that works out ok?

yeh i was going to go up 2 on the rear but i want the top end too as i take it to the IOM for wheelies etc but i still need the top speed for a good blast (about 110) as it is dangerous if you potter over the mountain,,,,, anyway,,,,,
i have some arrows on order now too as i have found a new set for 300 quid.
i am looking to get a NX cam as i have been told that they are far more tuned than a FMX cam, might even get my cam re-ground,,, i await my mods,,,
cheers again

GOT MY FULL ARROW SYSTEM,

excelent, it has really changed the bike. the weight difference is very noticable and the power is also increased. it will easilly pop the front wheel up no worries in 1st and 2nd and there is enough power to keep it up whereas there was not enought prior to the exhaust swap.
my carb kit is in the post but i cant find a set of cams so i will get my std ones re-ground at kent cams.
i am getting there, more power required !!

was that just the cans for £300?

or the full system?

If it was for the full system, pray tell WHERE FROM???????

[mergoofmx]

Full system was 300 nikka off eBay but is as new. i can get new cans for 300 + 70 ish for headers.
i REALLY recomend getting the full system as the diference is well worth the cost.!!!!

Did you add a K&N filter or dynojet kit? or did you just fit the full system leaving the fueling as standard?
i am looking at the full system after i have run it in.

Hi,

No i just have had to run it on half choke as i found it pulled better that way. ABP racing in germany do a Mikuni flat slide carb for it and i will be fitting it in the next few weeks so i will keep you all posted.

cheers

NOOOO problem, here are the links.

(power header) this is the ABP web site, you can also get a Mikuni carb kit from them which comes with a fuel pump for 269 Euro
the same company do the Arrow cans for 370 ish (they have gone up since i last looked 10 months ago)


here is the ebay link for the header,

check out the following link too, it shows dyno sheets up to 53.2bhp for a FMX with the headers, carb, cam and a little head work.(total about £1K but worh it imo
