Description
This package will transform your TPI to what it should be…
It includes the following:
- A new 2 piece TSP CNC machined cylinder head in Low, Medium, High or Very High comp. See below for more detailed explanations of each compression ratio.
- Reflashing of your STOCK ECU with improved fuel, oil and ignition maps developed by TSP…We modify both Map 1 and Map 2, with a more noticeable difference between the maps compared to the stock maps. Both maps have more oil everywhere compared to stock. Map 1 is the fully tuned map delivering maximum performance. Map 2 has less ignition advance and more fuel than Map 1 and is softer everywhere. Map 2 is the ‘safe’ map we suggest using for prolonged high speed riding, deep sand, or if you want to temporarily reduce power in very technical terrain.
- 50mm bolt and spring necessary to do the ‘idle screw mod’. Not always necessary to install but we supply it just in case.
This package makes an astonishing difference to the TPI and offers the following gains over a stock bike:
- Much more torque at low/mid revs, where you need it most, with a nice increase in power higher up in the rev range as well.
- Drastically improved 0-1/2 throttle performance.
- More oil than the stock maps for improved reliability… the stock 20/21 maps give significantly less oil than the previous year models.
- 2 ignition maps: hard and soft. The stock map switch works like normal to select between the customized maps.
- Much smoother, crisper power deliver at part throttle.
- Much less ‘pipe bang’… this is the annoying “dang, dang, dang” noise the engine makes on deceleration. Its generally harmless but very annoying and makes some stock TPI bikes unpleasant to ride at times.
- Safer air/fuel ratios at high rpm and large throttle openings so the engine is safer during prolonged high speed running.
- Better throttle response.
- You can ride in a higher gear with lower revs in many situations and use the extra low end torque to get you places with less wheel spin and much less clutch work.
Please note that the price includes the flash of your ECU. You will still need to send it to us and arrange return courier.
If you want us to install the kit, which also includes the idle bolt mod, then please add the installation option to your cart before you checkout. We will then contact you to schedule an appointment.
- Med comp combustion chamber option = For the novice rider.
- High comp combustion chamber option = For the more experienced rider.
