Replaced handlebar, handlebar clamps and bolts, grips, fork springs, and clutch switch.

Cleaned/lubed chain. Cleaned rear rim and tire.

Installed bar end weights to go with the foam grips.

Replaced shift lever and cushion.

Installed 1" long fork spring spacers. Adjusted my shock preload to the 4th postition.
I like it, so far.

Need to get dent out of gas tank. Need to straighten front fender, it's a little tweaked.

The good news is, I don't think I'll have to realign my forks. It seems to track straight/true.

The bad news is, after sweating me a@#$ off in the hot GA sun while working on the bike, I'm too tired to ride.
Guess I'll get some lunch and then a nap.
Maybe a ride after.

Foam grips are great. No more numb hands.

Dexron soaked rag is great for getting the gorilla snot (Motul O-ring chain lube goop) off of chains and rims. Plus, it kills the hell out of rust and lubes the chain.
Many thanks, gcrank1.

Progressive fork springs made a "Holy Mother of God" improvement in ride and handling.
I made 1" long spacers and they seem to be working fine.
Better ride. Better handling. No more vagueness when cornering.
No more feeling like it's going to slide out from under me in corners.
Much better cornering feel. Much more precise feeling.

Upping the shock preload to near max made a big improvement, too.

I was a bit nervous about my first ride in 25 days.
However, 5 minutes (or less) into the ride, I had an ear to ear grin on my face that wouldn't go away until about a half-hour after I got home.

Gonna try the hot glue paintless dent repair kit on the tank tomorrow.

Front fender is tweaked a little. It angles to the left a little. I figure I can straighten it.

Fork alignment is either spot-on or damned close. It tracks true whether I'm holding the handlebars or doing a "Look ma, no hands".

Did I mention that I freaking LOVE this bike?
Sure, there are bigger, faster, better handling, more comfortable for long trips bikes out there. Trouble is, this bike is just so much fun to ride.
Sure, it doesn't accelerate quite as quickly as I'd like sometimes.
Sure, it doesn't do the ton.
Sure, I'd like for it to do so.
Sure, I could sell it and buy a bike that does.
But, it just wouldn't be THIS bike. It wouldn't be an SR.
I can't see getting rid of this bike as long as I can ride.

I am 205 pounds and the 2nd shock position seems ok for me, maybe a bit on the stiff side.
I did the fork springs and larger tires to get some ground clearance mostly, and have not scraped the exhaust since.

You can get more power out of the sr if you want.

I do want more power out of it.
That will make it even more enjoyable for me, and keeps me from being tempted to sell it to buy a bigger bike.

Considering the fact that the 6.5 horse 196 cc Honda horizontal shaft (minibike and gokart) engine can be built to put out over 25 horses, I'm sure the SR engine can produce much more than it does.

I still think forced induction would be a hoot. Maybe not practical. Probably not going to happen to mine. Would be a hoot, nonetheless.
One of the minibike guys is using a 1968 or 69 VW/Porsche smog pump (a small Roots blower, actually) to supercharge his approx 200cc engine to 18 pounds of boost.
That same blower should put out 5-10 pounds of boost on the SR400s mill. I think he was driving it at a 1:1 ratio to engine speed.

The Turbo SR comes to mind also. It uses a turbo from a Daihatsu Tanto.

Ah, Mad Max. I love that movie.
I am a fan of forced induction.

Was that a KZ1000 that Goose rode?
