Thanks for the reply, Andy.
Just to clarify,the brass tube is between the main jet and alloy power jet cover screw. The main jets are non standard at 150,150. Since the PJ's (72,75) were still present, I opted for the nearest MJ size to the M-max set-up with PJ's(145,148, 75,75). I have increased the air intake areas into the air box, but could increase more, and done the splice etc. So, what you are saying is, the PJ's are now redundant ? My options are then, to re-open the tubes or use 185,188 MJ's. My preferred option, if possible, is to clear the tube. The reason is twofold, firstly I modify or manufacturer MJ's (bearing in mind warnings about the internal chamfer) and can only get drills in 0.05 increments. Secondly, I am only after a healthy increase in power, hopefully 60ish.
As an aside, you probably noticed I only became a Carbon member today. When choosing between that and Titanium, the only difference in the options, as I saw it, was the offer of discounts. So when I tried to enter the NSR discussion forum it then said Ti members only. Can I upgrade for an additional £15 ?
I look forward to you comments.
Thanks
Alan
