90% complete Yamaha G2 7" lift 50hp ex500 cart

Next thing i will do is cut up both engine harnesses, he kept both intact so he could go back, now nobody want too so i can chop everything unused out.

I shudder just looking at that spaghetti. She's going to be sweet when your all done.

Cool rig - Seems as if it is idling way too high but maybe that's just the video.

[cfherrman]

Probably, its supposed to idle at 1100, its up to around 2000. Hard to tell sound reflects off the concrete. Cheap ebay wired tach soon

Small setback, my truck has a lifter out and you have to pull the motor to change all of them so i am out taking the cart back to my brother for measurement and design, unless i measure at home, and im out about 3k to fix the truck. The wiring and the exhaust dont cost much so ill do those next. I might mess with the rear lift first, it needs to be stronger in the rear and a drop offset swingarm.

Here is a video of my brother neighbor at the off road park

It could be air but i think its the exhaust heat being trapped in the motor box and a lack of air moving around the motor. Ill get some more pictures when i can.

Im glad to hear your overheating is under control. I don't have my exhaust wrapped but most of it is in the air flow because I used the stock pipes which go down vs up. you should not have over heating issues on a water cooled engine due to engine compartment temps. High compartment temps would cause vapor lock if anything. It is possible that your thermostat was bad. I look forward to the pics.

Yeah it will vapor lock before overheating. I drove it around my neighborhood in the mud and learned more things. I picked up a pipe bender

Needs new chain
Belt drive
fender flares
Mirrors

Lol. Sounds like you got muddy. I would go with a bigger belt than I have on mine. I think the 500 would kill H100 belts. They are rated for a 20 HP electric motor which has way more torque than my 250 ninja.

Not much done yet, wont have big updates till i take care of the pickup. Went to my brothers house and got some cart things, chain, cables, speed sensor. I did some yard work with the cart, which is the reason i wanted a cart in the first place, muffler connection on drivers side fell off. I opened her up and fixed that and put on 32 links of new 50 chain. Chain was so rusted and wore that it was 2 links longer than the new. When i redo the motor mounts ill probably make the motor move to tension the chain. Right now its tight and quiet ill probably skip a belt drive.

Glad she quietened down for you. Would have been a pita to put a belt on I bet
