Finally after a lot of chasing, received the engine casings from the powder coaters, at first look they look good. Unfortunately on closer inspection I found that the cam cover has been warped, all thread holes have been powder coated and all gasket faces also coated.
The magnesium cam cover has been warped by the temperature of the oven at the powder coaters, disappointingly it is now scrap. I'll get another one from eBay in the US as they are far cheaper than the UK. Now got one for £35 delivered and should be here in a few days.
I eventually managed to scrape the powder coat from the magneto cover and re tap the threads in the casing and after a lot of effort its ok. I did the same on the clutch cover, however had a difficult time cleaning the shot blast remenants and powder coat from the oil filler. The starter gear cover is fully covered with powder coat and needs stripping and coating again.
All in all I'm not happy with the work and tried to get the powder coater to sort it but they are not interested. Will contact Karl at Extreme Engines to see who he uses or try to get a referral from other Hayabusa owners.
