homebuilt buggy bashing (tuned up)

More of my home built CB500 powered buggy. I tuned the engine at first then in the second half, after my kids in the wheel, I lowered the gear ratio. Those who thought I didn't have any torque, now it's geared to suit the power curve of the engine. I know it's not the fastest, but it is a whole new animal. The first of the video is with the engine tuned and with that I was running 32-34 M.P.H. through the gate. With the lower gear in the second half, on the first run I went through at 38 M.P.H. maybe doesn't sound that huge but it feels way different. On the last run obviously I let off, I wasn't expecting the wheelie. It was cool though!

nice build man people fail to realize how hard it is to make these work like this i am 90* done building mine its alot like yours actually but mine has a 540cc snowmobile motor and figuring out the clutching and how i have to run my chains so i have no slack was very very difficult!! because of my suspension independent front and swing arm in the rear

@deanthemotocrossman Thanks, yeah your right from drawing it up to driving it is a crazy lot of time and work. I checked your vid out looks promising! Let me know when you post an update and a drive video when your done! I heard you say you are using size 50 chain. Curious to see how it holds up. I started with 50, after snaping 50 and 50 heavy I settled on 60 heavy and haven't had any more issues. Best of luck to you !

y does it sound like u need to shift

[dazc3282]

It is just a high winding 4-stroke the power comes in from about 4000 to 9000 RPM. I am shifting much more in the second half of the vid. after I changed the gear ratio. but I still run it high RPM.

your tires should be Thicker in the back, like a quad's rear tires also wider removed from eachother for safety

[dazc3282]

I tried to keep it narrow so I could ride on four wheeler trails it is 58" wide. I have not had any stability issues or tipping problems yet. However if I were not riding four wheeler trails yes I would make it wider. The back tires are small for less suspension mass and less rotating mass and they provide great traction. Smaller/lighter tires are easier on suspension components and the drive train, less rotating mass also makes for a more responsive buggy, quicker throttle response.

at the start of the video the dog was black.... at the end white xD

I like the use of the rear Struts. What are teh springs off of and are you happy with the suspension setup? Are you running a strut and a shock?

[scramblerluver]

oh it didnt sound like it its keewl though

[Rolling1919]

Nice its quicker now, now y know why you dont use wider tires it depends of the terrain, use what you feel comfortable good job its areally cool buggy (Y)
