Might want to compare the drain screw to another one, it looks like part of it is missing.
Something is wrong, a 4-cylinder 750cc engine doesn't have a narrow power band that kicks in anywhere. I would question if your engine is running on all cylinders. Compression test would be in order and verify that all 4 cylinders are getting hot.... by the time the PowerBand kicks in ...
The way to learn about motorcycle geometry is to ride lots of different bikes, like very expensive bikes from Italy, Spain and Germany, then you have something to compare the differences with..... I'm trying really hard to read about geometry before I come on here asking stupid questions but it's fucking complicated to me because I suck at math. I learn better by making small changes and feeling the difference.
Except it's titanium, that was my BMW axle I was pricing because I knew Woody had some scrap beemers.You could probably get one turned down at a machine shop for peanuts....but then, it wouldn't have the zinc coating. I have seen Youtube videos where guys do home-made zinc coating - might be worth a thought.
If you want the good deals from the motorcycle dealers you start by riding with them or racing with them, yards like Woody's buy trade-ins from other motorcycle dealerships by the truck load, so salvage inventory is constantly changing. Even the owner doesn't really know what he has in stock at any given time there are simply too many bikes, the yard and storage containers have a thousand or more motorcycles in various states of disassembly at any given time and that's why a phone call to a scrap yard is useless. If you change your mind and want to make a road trip, come to my place first and I'll take you there to strip the parts you need, guys like Woody don't normally let strangers dive into the salvage yard with their own tools, that's a very special privilege.You guys are really lucky to have a junk yard that isn't totally picked over. I don't think its practical for me to travel that far. Off topic, I watched a documentary about John Britten tonight. It was awesome
First thing to do is determine the spring rates of the dual springs you have on there now, then select a set of springs that will have a lower rating. Single rate and dual spring setups are often preferred for racing or very spirited riding and progressive wound springs are better suited to pleasure riding because they soak up the tiny bumps and give a more plush ride. The spring rate is determined by measuring the amount of weight it takes to compress the spring one inch. With a progressive rate spring the low number is the weight it takes to compress the spring the first one inch of travel and the large number is the weight required to compress the spring the Last one inch of travel before becoming completely coil bound.Let me explain.... previous owner did this: View attachment 106540
These are so stiff I might as well be riding a hard tail.... just want something more pleasant. Not trying to drag a knee on this bike guys.... how the hell do you select and purchase hagons? Have you looked at their website? Is there a USA distributor?
