Welcome aboard Mike, ahhh the ole GN250... stock standard they are a little, well ok, a lot under powered, look like a postie bike and sound like a small child blowing a party whistle… but they are a good little bike, and yes I did once own one.
They are great to work on, and if you ask me a fun ride.
The only limit with modifying these is your imagination.
Where in Auckland are you based? There may be a Grease Monkey just around the corner that could lend a hand or offer some advice.
Love to see some photos, good on you for making yourself known and look forward to catching up on a “Meet up and Ride”. There is catch up this weekend at Salt Lake Cycles – Helensville if you can make it.
