Save money by
buying kit etc out of season during winter.
A haynes manual and some (decent) tools, possibly with some night classes at college, will help you do some of the work yourself. Tools aren't cheap, but good ones will last for years.
When checking electrical / engine management faults, look for corroded / broken / chafed wiring before getting it tested for codes etc. Sensor "failure" on a dignostic test is often down to wiring damage (no signal to ECU, confusing it).
Check what optional "extras" are listed on your insurance (legal expenses, recovery etc) and decide what ones you genuinely need.
When paying a bill (for m/c stuff, or owt else), some vendors impose a surcharge for paying by credit card (as opposed to debit card), so ask if you're not sure.
When buying kit, make sure you try it on PROPERLY. If you go home with it, and decide you don't like it, you might have a hard time returning it (how does a shopkeeper know a returned helmet hasn't been dropped when you try putting it back?). MAKE SURE you know their returns policy; "I didn't know" isn't an excuse - the rules are in the T&C's in the contract of sale. Failing that, ask: that's what the staff are there for.
