Re: 84 GS250FW-S

BUGGER!

I forgot to check the diaphrams!- They did look good though jammed
with babypoo coloured crap!

I was wondering if another suzuki 4 would fit??-ACROSS-GF???

Due to a lack of patience I will have to rig up, another filter
system! Perhaps a pod filter from a car would work??

As for options as to what pipe i can use there is nothing in
tamworth, so maybe someone can suggest somewhere within Sydney to
brisbane area???

Otherwise I was thinking of refabricating the headers......
"4 into 1 into 2"
And using twin 2" turbo mufflers from a car!

In theory this would allow greater torque, but.... I can't be sure as
to what factors affect these engines.

Someone (not from this site) suggested TURBO!???
And I just shat!

As I needed a new set of headers anyway and was looking for more down
low torque he thought it was an option,

The thought just scares me!

I read on the internet that these bikes have no power below 5,000rpm
and the torque does not arrive untill 9,000rpm.

I was wanting to ride at about 3-4000rpm will they do it?

The carbs are back in the bike and the headers are off awaiting reply
from you guys thanks heaps, you saved me heaps-so far $300
