Bike has been MOT'd today but just needs a couple bits sorted before it's ready.
One issue is with the carbs. During a test ride yesterday it won't pull cleanly above 4000rpm with the choke in. With the choke out it played ball.
The carbs have been stripped and ultrasonically cleaned and rebuilt with a rebuild kit, including tubes. It idles ok and new airbox to carb rubbers are on order as the originals are hard.
Are there any other area's which could cause this issue.
