Hi there, living in New Zealand, new to dirt bikes and just got a big problem, not of my doing. Long story short, bike held in WOT in 1st gear for approx 1mile. No compression after this. Pulled off head and barrell. Piston has picked up in three places, either side of exhaust port, right hand side of inlet. Exhaust port area damage mainly vertical scraping, visible and felt with finger nail. Inlet area approx 3mm diameter peice of electro plating gone and now located on the piston. Piston damage in same places, with aded note that aluminium piston material has burred over rings in a couple of small places.
So, WISECO don't do sleeves, anybody got any advice?
Local shop said whack in new piston and rings and see how we get on, but I don't want to loose the bottom end through shrapnel at a later date. They haven't yet seen the damage however and may change this view tomorrow.
