Hi

Cost of the FI kits fitted seems to be £150~£200.

Shouldn't screw the bike up.

All the best

It depends on the bike, Triumph kits will set you back £60 incuding fitting.

Mine was £200 from a Yamaha dealer - kit seemed more than just washers - the price certainly was!

All I can say is mine rides fine and has plenty of acceleration - it's an in line 4, 600cc. I don't know about other bikes.

If you buy a new bike, I'm pretty sure the restriction has to be free, if required.

Washers? Where are they placed? How do you know how wide a washer makes 33bhp?

FI Charge £150 for every kit (IIRC).

That means your paying 150 for 2 washers or a throttle pin, but the profit made covers the cost of someone paying 150 for a complete new ignition system etc.

Swings and Roundabouts lol

Then you ahve fitting to consider, which varies dependant on dealers.

for £20 i'll make you a restrictor, as long as you tell me what dimensions the washers need to be.(probably found out via email to F1)

im only making you washers to your set specification though, so technically im not breaching any scammery patents they have.

Can't you work it out, i.e. bike has 99bhp restrict 2/3rds of the intake.

It does not have to cost a thing

Anyone who gets the FI kit is a fool or has too much money.

What is the inlet size of each carb and what is the BHP of the bike.

close...

Every kit is dependent on the bike, an its normally £200 inc fittin on carbed bikes. All depends on where you get it done, you can buy kits off ebay too, that people sell on, or you can attempt to make one like mattsprak. But its just easier to have the official thing an fit it rather than measure a load of washers a drill them.

Easier yes, but £200 is a fair size hole in many peoples pockets.

I paid £40ish for My TDM FI kit on eBay, My Speed Four as said was £60 fitted direct from Triumph, I didn't bother with the GS. I would not pay £200 to make my bike slower.

There is nothing 'Official' about FI.

Depending on the power you take a 34mm out diameter with between a 19.5 - 20.5 inner diameter.

I would test it on a dyno to be sure. this is just a Theory/guess, but semi educated.


The way I worked it is

34mm intake diamter = 908mm squared intake area divide that by the power 99(or 90) then times by 33 = 303/332.


That is the area of the intake needed for 33bhp, then you just go back on your self to find the radius, divide by pi, sq root then double it. that will give you the inner radius.
