The Ultimate Off-Road Bonanza Gambler 100 Project

[Bonanza Bryan]

I like everything you are doing with this Brian. Nice welding and use of gussets in that neck. Very good engineering all the way around IMO!

Thanks Dave I try to build things right the first time and really think about what I’m doing to avoid mistakes. Maybe this is why I can’t sleep at night. Lol!

We have a roller

Thinking about possibly lowering the rear it looks like it sits a little higher than the front. I’m going to wait to test it out before I make my decision

Have you thought about a chain tensioner? You might need it with a large chain travel. I dig the bike so far!

Not yet we will see when I get into the test phase but I don’t think it’s going to be a problem considering my pivot point is relatively close to the jackshaft

So here’s where my engine is at. Should have had it done tonight except for one small problem. I DONT HAVE ANY VALVE SPRINGS!!! I know I ordered them they either didn’t make it in my order or I misplaced them so now I have to order a pair and wait on them. FRUSTRATED!

Bummer !

 

[owend]

That sucks! Hopefully you get them soon.

 

[Bonanza Bryan]

Should have them in Friday or Saturday so should be able to start it up and break in the engine this weekend. Then assemble everything and test it all out

Looks like it's going to be a blast to ride! Love me some Bonanza's!

Well haven’t updated this much but I have the engine built and the bike all together. The gas tank is just temporary until my fuel tank sealer finishes curing in my tank. I switched out the rear shocks they were much too stiff. Runs and rides really good the suspension works as I planned and the engine is a beast. Brakes work very well and the whole bike is really coming together. Just a few little things left like the kick stand, muffler support bracket, fenders, steering stops etc.... Probably won’t have it stripped down and painted before the race but other than that it’s a beast. My gearing is 12-20-14-60 for an overall of 7.1:1 great low end power and tops out a little over 50 mph. Thinking of changing the 14t sprocket out for a 12 and seeing just how much more low end I can get without making it a wheelie machine. Let me know what you guys think I’m very happy with it.

Very nice job. Needs paint! You might think about supporting the exhaust, so you don't break a stud on the Gambler trail. I like everything about it.

Thanks Dave I am going to do a support bracket for the muffler and most likely weld the muffler to the header to avoid anything breaking/falling off

 

[Bonanza Bryan]

Gas tank mounted and I welded up a bracket to support the muffler. Also switched out my 14t sprocket to a 12t and have much more low end now. The clutch is a little happier now it locks up and doesn’t slip anymore so I think this will be my final gearing for the race. Lost some top end but I doubt I will be riding it at WOT much

 

[MJL]

Nice! Let us know how the race goes!

 

[Mike B]

That looks muscular!

 

[mini one]

Nice! That race is going to be awesome with that bike!

 

[noseoil]

Great job on the build. Looks like a winner & should hold up really well for years to come!

 

[Bonanza Bryan]

Thanks for the comments. Today I will be converting to a 3/4” jackshaft I have all the bearings and gears needed the 5/8 setup has some flex to it with all the power the engine is making so the 3/4” setup should work well

Looks awesome. I'd go with Bonanza Orange like on the MX1500. THUMBS UP.
