Mongoose beast

I finally found some time to work on the Beast. I chopped frame up several months ago, Today I got the frame welded back together. I added 12" to lower tube, and added second bottom bracket for jackshaft. I won't need a chain tensioner for drive chain. I will need one on peddle chain. I still need to build motor mounts, springer frontend, and extend seatpost. I hope to have sometime to work on it next weekend.

I was planning on staying with flat black. I need to get some paint on the frontend, and on all the welds. With the high humidity at this time of year it won't take long for the welds to rust. A lot easier to paint before it rusts. Been out riding all day, had to go show the grandkids they love it. I plan on riding it to work in the morning(about 5 miles). Got a tool bag loaded up. I should ride the other bike, but what's the fun in that. supposed to rain later this week, I at least need to get a coat of primer on it.

The BEAST has been painted, still haven't decided what I am going to do for brakes. I think my next project will be to fab up a decent tank. I have a sportster tank, its just to big. I'm thinking along the lines of 1.5 gallons. Haven't done any tin work in many years, should be fun and challenging to make it look decent.
 
Update on the Beast: After 250 miles I noticed some stress cracks on the steering tube welds, added gussets to tube. At 500 miles now, everything seems to be holding up great. Just added rear fender, and taillight. Bike weighs in at 100 lbs., I have minimal vibration with the solid mounts. This bike is a real joy to ride. Max speed is 26 mph, I considered doing some gear changes, but have decided to leave it alone. Riding into a 35 mph headwind last week, I was still able to get 22 mph out of it. It can pull me off of standing start, if I slip the clutch a bit. I would say it is a good trade off SPEED for POWERIMG_20150403_142956.jpg
 
The Beast is still running strong, Didn't ride it much during the winter. With the springer front-end, it tends to push the snow, and slush. It is still enjoyable to ride.
Today I had the float stick, that happens occasionally. Still running stock plug, and cdi. Not exactly sure how many miles are on it now, odometer keeps resetting to "zero"
I am on 3rd rear tire, 2nd front. Still running with coaster brake only. This bike is as much fun to ride, as it was to build.
 
Replaced primary chain 2 weeks ago. There are advantages to running this short primary chain. The long secondary chain doesn't take much of the abuse of starting the engine, long chain is still in very good shape. Primary was worn out, the way I set up my tensioner requires use of half link (weak link) my half link fell apart when I removed chain. I didn't have another half link, so I welded pin on old one until I get a new one. This is my daily rider. Modified Mongoose Beast frame, 66cc GT5a, .65 jet, 41 roller chain
