Took it for a run yesterday but motored like an 3 legged dog (baaah)...

Limped back home and took the 180 main jet out replacing with a standard 160 (as per ellriders set up). Also swapped out for a standard (well a shiney stainless one) 350 pipe.

MAIN GOTT!!

Ran a treat - never run so good!

Might still get it to the rolling road as its ending its range at 70 (thats where the power band kicked in with my old 865 cam!!)

So no excuses, will be riding to Stafford!

Still not right then. Are you still on the same gearing?

You may want to try a 16 (80-85mph) or even a 17 if it'll pull it, unless your primary use is off road then leave it alone.

Glad she is back up and running mate!

Re gearing i'd go for 17 for road and 15 for off road......

he has to get some road time before he goes off road

Or get some good suspension on his 'you know what'

Took the wee beastie out for a bit of laning this eve with Alex and Guy. Ran ok but half way up a lane I smelled burning - the headers were WHITE hot!! Shut down and rested it a while. So its ok on the road I guess with plenty of airflow but running very lean. The needle is up by 3.6 already and Im running a 42 pilot. I could swap the K&N air filter out for a standard but would rather increase the fuelling than decrease the air - any tips?
