This has been a few weeks in the making. Not a whole lot of tweaking or mods, just some basics and some cosmetic enhancements. I replaced the spark plug, wire and cover as recommended (All NGK) and it DOES make a difference. Put on an oversized fuel filter, put zip ties on fuel line connections (not too tight, just snug) and siliconed the intake. My tensioner mod is holding up. Here are some ,model numbers of the parts:
  • Spark plug - NGKB5HS
  • Spark plug cover - NGKTB05EM-R
  • Fuel filter - WIX 33001

...and some pics.
Good idea with the chain thing. But the issue I've had before is not the tensioner sliding, it's twisting into the wheel...
Although I've fixed that problem by using some fine German methods. I applied the German torque spec to the bolts, gut'en-tight.



I haven't done much with my motorized bicycle lately. I moved from ME to NC (1100 miles), and brought it with me. Which ended up being a wonderful choice. About half way at 1AM my car broke down and left me stuck, fortunately I made it into a parking lot.
Next morning I pulled the motorized bicycle off my rack and rode it 15 miles to a parts store so I could get stuff to fix my car!
I have the carb tuned a little rich for all the hills in Maine, and so it gets enough fuel going down hill, and the 44t sprocket.
It's so flat here!! It's still kind of freaking me out, the town I live in has a maximum elevation of 20ft above sea level. So I could probably run a 38t sprocket and go FAST!

Thanks killercanuck!

Piston Bikes was the only one that said they had it in stock, so I ordered it.

I may still try to die cut the old one and have a spare.

I might as well start a collection of spare parts now if I'm going to keep playing with these things!

Hah, spare parts are evil and awesome. I have so many spare car parts I don't know what to do with. BUT I know for a fact if I throw any of them away I'll need it the next day.

This doesn't work so well now that I'm 1100 miles from home... But before, blow up a transmission in my car? No problem, have it towed home, put in a new transmission that night then drive it to work the next morning.
Spare parts are a wonderful thing...

Doing preventive maintenance two days ago, I noticed one SS 14g spoke broke its tip @ the hub. That was fixed, new bike chain installed and both chains greased. Engine idle was turned down; bike sounds mellow now. Opti-2 oil is in my reserve bottle, awaiting its first time @ 100:1.

Sparkplug shows chocolate brown, a shade richer than its previous cocoa-brown. I had adjusted the carb to make up low end torque for the taller tires.

Rode my bike to the blood bank yesterday. Nurses there shared how a donor who'd given 200 times before, had fainted shortly after giving platelets. We donate every two weeks. Blood donors give every eight weeks.

That kinda spooked me, since I rode 5 miles in on my MB. So I rode home on the sidewalks mostly, @ slow speed.

Note to self: Do NOT ride to blood bank on your motorized bike!

I used to sell plasma twice a week, and never had too much a problem. Of course, I always had an energy drink for when I was finished. I surely don't wanna nod off while riding!
