If you've passed your A2 test and are restricted to bikes with 33bhp or less you have a couple options: Buy a bike with less than 33hp or buy a larger bike that's restricted. This can be done by others or by yourself. Contrary to what many people believe it is not a legal requirement to have a restriction certificate, so this allows you to do it yourself if you feel up to the task. for more info: http://www.themotorbikeforum.co.uk/view ... 27&t=23787 Having bought a hornet 600 at age 19, I am unfortunately forced to restrict it. When I bought it it was not restricted, but had been previously, so the chap I bought it off still had the necessary washers, otherwise eBay can normally provide for not too much. So I fitted the restrictors myself to avoid garage costs. I realise that there are some other guides around, but many do not go into much depth, and the difficulty can vary on each bike. I would recommend to anybody planning on doing this themselves get a Haynes manual, great help for all sorts of diy fixing and servicing on your bike. Decor58 has written a good guide for his 98 GSX600F here:http://www.themotorbikeforum.co.uk/viewtopic.php?f=5&t=37490&hilit=restrictor This guide is for 96 - 03 honda cb600's, it may help for other bikes however. But if you screw up while following this, i'm not responsible Try not to get any dirt/fuel/dust into the carbs as this can affect how your bike runs! Here goes: Step 1: Make sure the fuel tap is OFF before doing anything!!! Step 2: Take off the seat and the side panels Step 3: Take the tank off, watching out for small amounts of fuel left in the hoses coming from the fuel tap. Step 4: Disconnect and take out the battery Step 5: Take off air filter housing, remembering to loosen fittings that attach it to the carbs, also good opportunity to clean/replace the air filter. Step 6: Disconnect the battery cable from the carbs as well as all hoses going into it, that would prevent you from taking it out a few inches, it may not need to come off 100%, just enough for you to get at the other side of the carbs. (The haynes manual advised me to drain any fuel out of the carbs, but i don't think it was necessary) Step 6: You can now see the correct place to put the washers! Step 7: Do the opposite to put everything back together! Congrats! You have now successfully (maybe) restricted your bike, now just wait 2 years and do it again to take them out, then resell your washers on eBay. Questions? please ask me in comments. I have more photos, if you need them, i advise taking pictures of each thing you do, this will make it easier to remember where each bit goes! It took me about an hour and a half to do, this was my first time doing any job like this, and would probably take less than half that time to do it again. Good Luck!
