| i have new crankcases if you find all other parts you need
i wont part with my AC rep top ends as they are getting too hard to find,
i have almost finished throwing a hybrid AC blata engine together with the genuine top end i got from ben from WBR
i must say im very impressed with my first euro top end kit a big thanks to WBR hope your happy with your quality 40cc 4.1 rep kits + spare stocker
another thing to look out for if building up in parts there are 2 types of blata rep cases one needs coil spacers the other dose not, but the coil brackets (plate) are hard to come by |
