1177cc big bore for F/M 1000 200hp+

Take your M1000 mountain sled and make it a Beast!

These 1177 engines outperform the competitions with a full port job and billet head for better cooling and making more hp then others using a modified stock head. We also have porting specs for turbos, low elevation riding and high elevation riding.

Terra Alps Racing has different compression ratios for running pump gas at low elevation or high elevations, also race gas set ups. With interchangable dome inserts.

Send in your cylinders, and exhaust valves. We bore and fully port the cylinders. Re-plate the cylinders then re-port the cylinders to spec and polish the exhaust. We can machine your stock head and install interchangable dome inserts for the sleeper look!
