This is correct, single cylinder four stroke cranks are usually pressed together crankshafts with ball bearing pressed into the cases very similar to a watercraft crankshaft, but most of these engines are used in four wheelers and dirt bikes.There are of course some four stroke single street...
You are talking apples and oranges here, four strokes have plain bearing cranks which require a pressure fed lubrication system and at least 40-50 psi to operate correctly, more rpms than stock, higher compression etc requires more oil pressure. Two strokes have no pressure fed lubrication and...
I know for a fact the NGK boots are resistor type boots however Kawi used some different kind of boots other than NGK on some year boats, I do not have a set here at present to check and do not know if they are resistor or not.
Truefully as long as you are using regular glass and epoxy resin you could do it either way,like you said swiss cheese the aluminum and take it one step further, rough up the whole surface of the aluminum with a grinding disc for better adhesion. Encapsulating aluminum with fiberglass is nothing...
Been towing with a Toyota 2x4 with a 22r for years, double trailers with sitdowns on them and even a camper all the way to Atlanta and back a few years ago, shouldn't be a problem.Just don't go putting huge tires on it as it changes the gearing where it won't pull squat.
The only really good thing about being in the PWC repair business is I don't have to hide chit. Another ski in the yard draws no attention whatsoever. Boxes of parts being dropped of via UPS are common fare. Me spending all day grinding and glassing is commonplace here,plus no one is going to...
I find this to be mostly correct, most of the SJ's I have ridden had straight bars and stiff handlepoles, two things I absolutely cannot stand. I have a SN I am building for next year,I will get the chance to set up a ski like I want it and ride it, maybe then I can see what all the fuss is...
Personally I am really glad to see it moving away from a one size fits all mentality. What works for you may not work for me, for years I have ridden peoples Superjets trying to figure out what all the fuss was about, I still haven't figured it out. My skis work for me and the kind of riding I...
The thing with enamel is it takes about 30 days to air cure,so no sanding, buffing etc for 30 days the urethane is good to go 24 hrs later, sand it buff it do whatever you like.Some of the best high end paint jobs did not come out of the gun that way they were scuffed and buffed after spraying...
All true, Acrylic urethane was originally designed for use on aircraft,it needed to be durable, have a tight bond to the substrate material, be cleanable,fuel resistant and slick, urethane is all that and a bag of chips.
