Sound like your problem,your decompressor is way too tight
The way to adjust the decompresor,is to add .0.25(for 05 and after model) to your right side exhaust valve clearance to find the measure you should adjust the decompressor.
For exemple ... if your right side valve exhaust clearance was 0.28mm (stock spec),then you add 0.25mm and you will adjust your decompressor to 0.53mm.
The trick is too add 0.15mm (for 04-05 model) and 0.25mm (for 06 and later model) to your right side exhaust valve clearance to find the measure that you will adjust your decompressor.
I have adjusted 2 450R this week like that and the 2 run fine !!!
