Yes, many times, you can also get the extra 2 litres of fuel the 00 model has. Just drill the small hole out to 5mm in the filler neck, and fill until you see it's level with the hole. The 00 model just had a shorter filler neck, which does the same thing. CAUTION, CAUTION when you drill out the hole you MUST empty the tank and fill it with exhaust fumes from a diesel/petrol engine, or you risk EXPLOSION of fuel vapour from hot swarf off the drill. Assuming you've got a car or something, run a pipe into the tank, run the engine for about 10mins ish it will expel all the petrol vapour and drill. You have to drill at a slight angle unless you've got a small angle drill head. Use a cocktail umbrella (or something similar) with a lengthen shaft and increased edge, to catch the swarf, push in open. WARNING know of owners who just drilled, with fuel in the tank who then lost their eyebrows, hair, tank and burnt the bike! Don't say I didn't tell you.

Some will just say drill it, yer you could get away with it, do you really want to risk it? Especially now with what all a trip to hospital could mean! Stay safe mate.

[/quote] 40 miles on 2 litres??? That would be 440 miles on a (now modded) 22 litre tank. Average mileage is 45 miles per gallon.

Yes, those figures are as much good as car manufactures, they're based on most owners who don't ride all year varying levels of experience etc. I did say depending on how you ride, now if you're a point and squirt merchant, you'll get figures like those, a bit also depends on the bike. I used to commute in/out of London 5 days a week A1, A406, Hanger Lane, I don't hang about ride quick but smoothly, I used to get 56 ish MPG, with a range of 260 - 5 miles before it run dry on the modded tank. I always carried a 2.5Lt can and would get caught out a few times a year, pushing the extra 5 miles.  I think you're find that's 20 miles per lt or there about's. It's all about the right wrist, gearbox and level of skill, you've either got or you haven't  Also a 98 - 99 models had 18lt, 00 - 01 20lt same tank just smaller neck filler. 02 - on 22lt different tank.

I have always averaged about 10 miles per litre (45mpg) on my FZS600, ST1100 and CBF1000 with mixed riding. My FZR1000 was (quite) a bit thirstier.
Comuting on the FZS600 into London from Sussex averaged about 50mpg
Another ex-Fazer rider that is a foccer again

Same as, I've always used 10 miles per litre as a decent gauge, obviously give or take, but i'm always riding in unavoidable traffic, so i expect to use more than a fluent motorway run for example where I'm moving at a constant pace. Not even worth me doing the Fuelly thing because my journeys are not a true example of fuel usage that the bike is actually capable of.

Wonder why the 2000 model on both charts has the better mileage?

I did this mod when I had a Gen 2 Fazer 1000. I just used a long sharpened tapered punch. No drilling and the associated swarf etc. Easy peasy !
