Somekind of fork brace would make a big difference to the steering, even if you simply cut up the front mudguard ... I was always taught that forks work best as a complete unit rather than two independent sides.

I would have to make something that clamps on to the top of the lowers. If you look carefully all but 1 of the mounting points have been Removed.

Well engine has been giving me some trouble. Long story short, had to helicoil one of the spark plug holes, and replace the coil. Otherwise bike's been great. The volume of the exhaust finally got to me, ordered some longer/quieter mufflers, which was inevitable I suppose.

Nice nice build there jag. Learnt a few things esp the timing placement you did.

So I've been playing with fine tuning since I need to save some funds before I rebuild the 360 motor I have.  Played with the carbs a bit and then had an idea with the new mufflers. I removed the packing, and wrapped the baffles in exhaust wrap, essentially  making it just a straight long pipe. Yes it quite loud,, but I be damned there was a noticeable improvement in acceleration. Kinda cool I thought.

Hmmm, says right in the clymer manual to apply on both sides of the gaskets.... head was torqued. The gaskets were hard as shit too which I know makes getting a good seal almost impossible. The gaps in the pistons rings weren't spaced correctly either, but no idea if that happened as I took it apart or not.
The only time the gaps in the rings are spaced correctly is when you put them there. As soon as the motor is running they are constantly rotating in their grooves. Spacing ring gaps is a wives tale that has been proven to not matter at all.

good to know... As luck would have it I was able to order a set of fork uppers today, so goodbye to the old cruddy ones. That was pretty much the only thing I wasnt able to change.

I really like the bike.  But, to me its just screaming for a pair of nice chrome fenders.   ;)

Probably make a world of difference in handling too.

Haha I just cant get into fenders on it.  I really never go more than 50, and it rides amazing for what I ask from it so I'm happy. Even lowering the front end a little didn't make any appreciable difference at those low speeds, so the aesthetic won over the function on that as well. I was planning to change the seat to something more fitting but its really grown on me. Im honestly shocked I found someone who makes new forks for it. other than shortening the cables thats all I have left.

False.

Spacing ring gaps on assembly is required for optimal break in on high performance engines.

Make your own decision. Take 1 second to stagger the rings, as every piston manufacturer suggests to do, or take marcs advice and line the gaps up.
