gas bicycle engine kit installation update and tips
I have the kit installed and have been breaking in the engine for the past few days. Will upload some pictures in a couple of days after I finish up some mods.
Some lessons learned and tips so far.
Use 242 loctite on ALL bolts on the bike. I used loctite on the mounting bolts and a few. Normally this is not an issue but my rear brakes were not working since I was just going for a test drive and was still getting the rear brakes lined up and adjusted. Since the bike has a motor it acts like a slow brake when you let off the gas so coming to a stop was not an issue. The bolts that hold the gas tank on came lose a few hours later so I will ad some loctite to those as well. Basically if there is a bolt you don't want to come lose then you should loctite it. These engines vibrate pretty bad at high RPM during the break in period so loctite is a must.
add some rubber or padding in the motor mounts to reduce and prevent vibrations. I hear that once the motor is broken in after about two tanks of gas the vibrations are pretty much removed but I don't think it can hurt to add some rubber padding to the mount bolts while doing the install. I have heard of people using cut up inner tube or tires so I went to peb boys and got a 56 piece tire repair kit for around $7. It has all kinds of pre cut shapes and sizes of rubber which work great as a vibration reducer. I already added some between my gas tank and frame. Not only does it remove the vibration but it also helps get a better grip and improves the contact area. I purchased some black silicon caulking from home depot which I will use to fill in the cracks or spaces that look like they may help reduce the vibrations.
The stock spark plug and wire are pretty cheap so I bought a new set from sickbikeparts.com they seem to have the best prices and ship priority mail so you get your package quickly. I went with the NGK BPR6HIX Iridium Spark Plug it was only $6.99 compared to the NGK B6HS Spark Plug which was $2.49 so for a couple bucks I figured I would go with the better plug. The Magnecor plug wires were $6.49 so I didn't really break the bank on this purchase. I also ordered the Heavy Duty High Performance Air Filter at $17.95 as well since the stock filter is pretty cheap and doesn't allow for much air intake. While I was at it I ordered the "Clutch Cover for standard Chinese 2 Stroke engine" which is supposed to reduce the noise from the engine this cost a woping $5.95
Will add some photos and update on additional upgrades soon...
