reading many forums whilst playing with accesories i found alot of reports regarding intake valve adjustments early.
At 1500 i strongly reccomend you check them yourself as i trusted it to be done in the workshop service (stupid to expect detailed maintenance unless you do it yourself!)
It apparently was checked , but later admitting that it wasn’t
at 3200km i found my bike having trouble starting and started making enqieries
thankfully the shop took my suggestions on hand and had a good look
Intake was to tight and the shim needed replacing , so there was my new bike in bits because of know it all mechanics whom think they know it all (regardless what inspection scheduale states)
IF YOU OWN A 450 TAKE NOTE AND CHECK THOSE VALVES EARLY AND FREQUENTLY AS IT IS A COMMON PROBLEM THROUGHOUT MOTO THREADS
GOOD LUCK FELLOW QUACKA HEADS:silly: :kiss:
