JPR Motorcycles engine tuning service is available for the majority of motorcycles. With many years of experience building and tuning a range of engines there’s no job too big or small.  JPR Motorcycles can offer all types of specialist engine work such as: cylinder head tuning, up-rated parts, crank balancing, super finishing, barrel re-plating.   If you have fitted and new exhaust, air filter and fuelling module, such as a Dynojet Power commander, the next step for more performance is to make internal engine changes.  Of course not every engine build is to gain more power, so more simple engine repairs and rebuilds can also be carried out at the same high level.  Be sure to have a look at my CBR1000 engine build blog for an example of my engine work.  As every job is different please get in contact to discuss your requirements.
