Like this one:Here
I couldn't agree more, and $25 is a great price for a 1200 Lumen CREE T6 LED and LiPo battery back!

I was paying $40 for them and happy to pay it because I have seen first hand countless times a driver that would have crossed my path because they misjudged my speed slam on their brakes.

It only took that single broadsiding of a van when I was hauling donkey downhill without a light to never ride in daylight without a strobe again just like I never ride without a helmet. That helmet by the way was very damaged and had to be promptly replaced.

Along the same theme I urge you to make sure you have 2 good brakes or no doubt you will find out how good your helmet is first hand.

One last thing is forget tire slime even it is free, it is a messy pretty useless temporary 'after the fact' bandaid that simply will not last long.

If you use an HD tube and put a good liner between the tube and tire you can pretty much kiss flat tires good-bye.

[Ba great upgrade we all should do if I could just find them non NPT I drilled and tapped my tank due to the worn out threads and other reasons it works sooo much better no more puddle or drips or any of that BS we get with the stock cock , however I found out if you take the stock valve apart and flip over the 4 hole rubber shlt valve it works wonders for a long time. At least it dd for me.

My wife ordered this "under the cabinet light kit" it was to be for "HER" weekend project
2 months later I ask whats up with this holding a tangled mess of wire and round low voltage lights ..Just throw it away she said I asked are you sure I can put it up for you no she said I changed my mind ok "To the motorized bicycle we go" i mounted on light on the fron ran the wire back tothe rck standing there scratching my head wondering where can I get a power source I needed 11 volts and bing the lightbulb in my head goes off the FIOS guy came the other day and inside the modem he mounted on the baseboard was a bran new 12V 8 hour battery !!! justifying I cant use the pc if power goes out what the heck do I need a bat. back up for needless to say I stuffed it in my leather tool bag it fit perf. ran one wire directly to the light the other to a switch I mounted on the seat post and I also hard wired a quick disconnect and left it dangling so instead of pulling the batt. out to charge it I can just pull out the pigtail run it to the modem plug it in plug it in charging it over night . This light is sooo bright I cant believe it.

I want to go to Benny's and get some of that lens red tape and mount two more on the rear for tail lights ... OH YEA and after I made this post I went back and put in a disconnect so I can remove the bad quickly stress free , I rarely do that though as the other side of the bad is filled with every tool I need. Thanks fer looking folks!

Modified needle bearing made to fit bushed wrist pin hole

I bought a cheap motor online that used a wrist pin bushing but after a summer of riding the bushing began to go and needed to be replaced but i could not find anywhere that sold them. somewhere along the line i purchased a spare piston set online that came with a wrist pin needle bearing and i found that if you remove 3 of the needles evenly spaced that it will fit and work quite nicely in the wrist pin designed to fit the bushing. I have been running my bike for about 6 months now with this modified needle bearing and it is still going strong.

the chain is probably just rubbing on the housing. this has happened on several of my engines in the past. the first few rides i could here the master clip on the chain hitting something in the housing every time it went around but after it rubbed some of it away everything worked fine

i checked that even dremeled the inside where the chain was actually hitting , it does it every like 3 chain links if I measered them between sounds and I can feel the clutch spring tightening then popping free I think something is binding the spring inside the brand new casing then freeing up weird cause it will go away then just as quick return Also when I went to feed the chain during the install I had to literally pull it it with all I had just to get it to spin ..no plug in clutch fee

it looks as if the front gear is slowly moving outward it was almost flush at first now it is like a half inch out of alignment perhaps gears aren't meshing.and thats causing the occasional clunk
I can even see the rubber seal where I couldn't before

how come the ports on all of these engines are rectangular and all of the ports on the inlet and exhaust are little circles? is this hurting my performance?

Thumbs up Re: Motorized Bicycle Take a Tip...Leave a Tip

Years ago our 10 speed Italian rockets were very sensative to balance even after good spoke tuning. Taped on lead weights or wrapped on skinny threads still had a chance of shifting. Some of us farm boys used split lead shot, comes in any weight you need and once squeezed on the stayed put.

Just my $0.02.
