evening guys!! just came to show off my 610 if anyone Is interested started out life as the 350, had the cases bored, acquired necessary parts to 'make' a 610, barrel, head (ported), crank, rod, sprockets, timing chain and a 100mm piston. took me about a year to get to this stage. mostly because of funds partly because iv never rebuilt a bike before and had to learn A LOT! it's certainly not finished more a work in progress. would love a 99 set of marzocchis. really need the brembo up front lol I'm extremely chuffed with the bike. starts first kick every kick, makes power EVERYWHERE and wheelies on throttle alone through the first 3 gears and slipping under load in 4th if I'm harsh on the throttle. another niggle to fix but we'll get there can't wait to get out and chase and probably smoke some modern machines all in all I love this absolute beast of machine and quite chuffed with myself also
