hi guys, can anyone help i have a 18 terra sp i brought on import this year apart from striping out the backend and cleaning it all up i have done nothing more. it start within half a dozen kicks but seems to run cold on one side and puts out unburnt fuel too. it rode ok in the summer and had the speedo off the clock. it has done high millage i think i may have to rebuild the engine . any advice would be great.
