Haven't posted in a while since solving the excessive cabin noise issue, so I thought I would share a few upgrades to my Sector... Realize that this is driven daily on the street, so some of the mods are to make it more streetworthy.
Locking gas door.
Rear view mirror.
Modified windshield for better airflow in cabin.
Lowered and modified headrest bar for improved rear view. Tailgate protector.
Folding armrests.
Overhead utility rack. Keeps the interior cooler and dryer, too!
Folding rear seats.
Dust cover and seat protector.
If anyone wants links to the rear view mirror, seats, or arrests, let me know and I will post. But know that everything requires some level of fabrication. The utility rack was all custom built. Cheers!

looking around and cannot find and Stampede motors, the Havoc looks to directly bolt in, with exception of the larger displacment. has anyone looked into this further? seems to be a better option considering stampede engines are on backorder.

Bought my 2009 Yamaha Rhino, (fuel injected of course), recently from the original owner. Only had 500 miles and 70hrs. Starts reliably, however, it will not idle but about 50% of the time. Also, when driving slow in low or high, that is to say, relatively low rpms and below about 10 mph, it bucks and almost wants to die..... not smooth at all. However, at speed (say 12-15 mph or more) it runs very well, like it should. Any ideas?

After three years, my Sector completely died. Something caused the hot wire under the seat from the charger to disintegrate, so the batteries weren't being charged. The batteries weren't charging 100% anymore, so decided to convert to lithium.
As most others have done, I went with 4-48v batteries in parallel, as I believe that will be plenty of amp-hours for my needs, but can always add more if needed. I went with LiTime wired CAN batteries and mounted their digital gauge on the dash above the current one, which fit perfectly. I didn't think the existing battery brackets worked well for the new batteries, so made my own out of aluminum L rails, which makes it much more secure (and saves a few more ounces :)). Since I wired them in a 'balanced' configuration, I had to make all new cables from 0/1 gauge wire and 8mm posts. I updated the DeltaQ charger to profile 233. Cleaned everything up (I must have vacuumed 20 pounds of dirt!), put it all together and... wham!
So far, it definitely is better than with the original AGM batteries. Sustains speed better going up hills, and seems to have plenty of reserve current. The difference in weight with 4 LiPo vs 8 AGM batteries surely doesn't hurt!
Thanks to everyone on this forum, but special shoutout to GNFO who was a big help.
A few questions:
In the 'any tips' thread, EVSupport mentioned reprogramming the Sevcon to reflect the new discharge curve of the lithium cells, but I didn't see any more info about that or how to do that. Is there any more info about that?
Have folks replaced the onboard 12v battery, and if so, with lithium? I'm not sure why there is a 12v battery; why didn't they just step down the current of the 48v system to provide power to accessories?
Is there a recommendation as far as charging with the lithium conversion? As far as I understand, it is better to let lithium batteries discharge somewhat (but not completely) than keep them charging all the time. What do you think?

Hi Team,
I'm new to the Forum, and I'm looking for your help. I have a 2009 Yamaha Rhino 700 that has stopped consistently charging. Here are the specs and Info I can provide, the Stator and Regulator are new. The Stator does not have continuity to ground on all 3 wires at the engine bay plug. The stator puts out 15-17AC/V at Idle and 38-39AC/V at 2000rpm at both the engine bay plug and the regulator plug. The Battery regulator plug has Battery DC Voltage, when Running the regulator puts out Charging voltage 13.4-15V. I have upgraded/added ground wires from the primary battery to the engine block, from the stock ground wire bolt on the engine to the Chassis and from the secondary battery to the regulator grounding bolt/ground wire. Now the symptoms are it Charges when first started and will continue to charge while driving or at high idle until the machine returns to idle- it will not charge after that, this includes any RPM. If your shut the machine off and restart the process restarts -it will charge until returned to idle. The Machine has and RM Stator and Regulator and a Kimpex Flywheel. The last time it was driven it had an overheating event- unrelated to charging I think, but worth the mention.
Any thoughts would be helpful, I have the factory Regulator- it was working at the time of replacement- when swapped the same issues occur.
