SmedSpeed XS650


starter motor conversion kit

Smedspeed Tuning in collaboration with Guilford Motorsport Fabrications brings you the enlarged oil reservoir conversion. From a wholly original idea, making good use of the defunct starter motor on your latest creation, the starter motor ends are removed and a new 6082 billet aluminium body machined to suit the existing Hitachi starter ends.

These are professionally TIG welded together and an additional drain plug added C/W Dowty bonded sealing washer.
The Smedspeed converted starter motor body adds an additional 400cc to the oil volume; this is additional to the 350cc from removal of the internal starter gears. The XS650 engine is renowned to run hot - adding the cumulative totals of the two options increases the oil capacity to 3.35 litres, an increase over standard of 30%, oil temperature is significantly reduced.

Our conversion doesn't alter the crankcases in any way, and thus the conversion can be removed and the starter gears may be re-installed if required at any time point.

The kit is on an exchange basis, all I require is your starter ends to modify.
