Comes complete with new bolts
When choosing the correct spacer for big bore gear sets, simply count the teeth ratio difference your going for from stock.
Ie. For 27/50 gearing (ideal for 46cc) , this is 8 teeth larger on the pinion but also 8 teeth smaller on spur, therefore it needs the same spacer as stock (19T)
For 29/50 gearing (Ideal for 65cc), this is 10 teeth larger on the pinion but only 8 teeth smaller on spur, therefore it needs a 21T spacer (2 sizes up from stock spacer)
