1998 Yamaha G16 + Polaris Scrambler 500 project
Hi guys. I promised Smallblock that I'd start a thread for this build in the appropriate section, so here goes!
I found the cart on craigslist. The G16 engine had blown a long time ago and the guy had found a 2001 Polaris Scrambler 500 that was wrecked. He said the engine was running when they took it out of the ATV. It appears that they got all of the wiring, radiator, fan, oil tank, new Polaris belt, carb, Polaris main clutch, all of the exhaust parts, fuel pump, etc...The guy got as far as building a plate on the engine cradle and then lost interest and let it sit and start to rot in a field. Not sure why he gave up such a bad azz project This will be my third cart project. First was a G9 with a Kawasaki motor cycle engine, second was the G8 project, and now this one. I rescued it, brought it home and started tearing it down. I decided I wanted to know exactly where the cradle was going to sit with the lift before I mounted the motor, so went to work cleaning, removing what little rust was there, getting rid of all the black widows and yellow spray paint, priming and painting. FYI - this is a TOTAL tiny BUDGET build. Would love to throw money at it, but since I've already done this with our current Yamaha G8, the wify won't let me spend any big bucks at this point!! I was lucky enough that she said I could make this purchase!! So far: I built a 5 1/2" lift, using Pachanga's receiver tube idea, added 400ex shocks with a new custom bracket (moved the A-arms forward by 1 1/2"), changed out the A-arms from G16 to G8, which were longer, tore apart, cleaned and adjusted the brakes. I have also moved the engine cradle support under the main frame, instead of on top as stock, to provide a flatter cradle to get the motor at proper angle and provide for more clearance of the carb. At this point, I have no idea if the motor is good, except it seems to have good compression by turning the clutch. My goal is to build a trail machine that can keep up, or at least close to RZR's without 4 wheel drive. I'd like to have it ready by summer and bring it down to CAW. Progress will be a little slow, but consistent! |

Re: 1998 Yamaha G16 + Polaris Scrambler 500 project
Heck yea Chris! Gotta keep up with the joneses (you and Tom!!!!) on those midnight trail runs!
Here is where I am today. Trying to figure out the best way to mount the motor. I want to have some type of adjustability, so I can move the motor forward in the future to tighten or loosen the belt. I'd love to see what other guys have done to combat the issue. My thought at this point is to hard mount the rear mounts down through the cradle. Then use this arm on the front mount that could be brought up or down. or forward/backward There is another mount on top of the engine on the opposite side. Not sure I'll even use this mount, but just don't know if this will be strong enough.....Any idea's? |

You'll have to figure out something forward/backward. I think up and down will mess with fuel flow with the carb. But if you hard mount the rear motor mounts you'll lose the forward/backward option. Hmmmm.....

I can always cut slits in the cradle base for the rear bolts, so they can slide forward/backwards.

Slot the rear mounts and use a turnbuckle mounted where that allthread looking rod is mounted to loosen or tighten the belt. Put stopnuts on the turnbuckle to lock it at the tightness you need.

Re: 1998 Yamaha G16 + Polaris Scrambler 500 project
Very Cool! Glad to see the build thread and seems your stooked to make it work On your motor, where exactly are the motor mounts located and how many? Seem's like you have plenty of clearance (from top of engine to seat) and the angle of the engine looks correct also looks like you have plenty of room between the engine and transaxle shifter lever. I wouldn't be so concerned about adjustability if you have a belt (kevelar preferably) and build the mount's to suit it. Just vision, removing the tin splash sheild and welding flat tubing (front to back) and welding engine brakets. Keep the faith my freind, this is going to one killer ride when your done

Re: 1998 Yamaha G16 + Polaris Scrambler 500 project
Ok, think about this...rather them flat tubing, just weld a steel plate in the swing arm area, then you can make your "slotted" holes and the engine would realy be protected. Shure some pix's of the eninge mounts would be great. I don't have Photo Shop, but many members do (like Rifter) to help with the desighn. Where you talking about "Yamahahauler" being a customer car?
