I am actually asking this for a friend. We were doing food plots yesterday and he has a like new 650 Rincon, not sure what year but can find out if it makes a difference. We would drag a homeade harrow over the food plots to smooth them out and the bike would constantly overheat and we would have to wait a while for it to cool down and then start back up again. Also, the gas in the tank would start to boil and he has a vent gas cap and it was venting fine, but the gas would still boil. What can be done to solve this? I don't want to hear the radiator was dirty either because he keeps it immaculate and if a little dust on the radiator makes them run hot there is a design flaw somewhere. The bike is geared extremely high I've noticed and I have heard of a programer chip available for this bike. Would that help? Have also heard of Engine Ice. Would this make a big enough difference? If anyone has found a way to solve the problem please let me know. I realize this bike is suited more for trail riding but would like to find a way to make it more of a work horse without him having to sell it. Thanks.:frown:

The running hot is more than likly due to the high gearing makink the motor work harder, i have a 700 grizzly and the gas does boil on it also well not boiling but an excessive amount of rumbleing when it is hot outside and been hard riding a while my guys at the shop said with big motors and all the plastic around them they will do that but back to the running not knocking the Honda as i own one to and love it but it does not have the pulling power that the Yamaha does i have hooked to the 650 Hondas in a tug of war and can drag them anywhere i want to but is a good for trail ridin . and be very care ful when removing the gas cap when that condition exsits.

Its not the gas "boiling" its a rollover valve on the tank vent not venting pressure fast enough causing the boiling sound. On the Yamahas they were too small from the factory on the 07 and some of the 08 models.Im not sure how the rincons vent system is set up but its most likly is very simular .As for the overheating issue its like

Rincon

The vent is set up like the regular old tube out of the gas cap. I checked the tube to make sure it was venting and not clogged and fumes were pouring out like there was no tomorrow. I do believe that the motor was putting out a substantial amount of heat to make the tank hot enough to do this. Has anyone heard of a programmer chip for this bike? Seems like it may help and was wondering if anyone has tried it with any success for this problem. It's funny how we would work the old 300 hondas and my 400 Big Bear all day and never had a problem. Maybe some of this newer tech. ain't all what it's cracked up to be!:wacko:

You also have to remember the old 300 hondas were bulit proof thats why Honda does not make them any more and the 400 big bear like the 300 honda were air cooled, and geared different.

HE may can try a taller tire set up to alter his gearing rather than going into the ring and pinions??? just a thought??

I agree with Moose, You could also get a mudders clutch kit. A lot more torque, that is what you need. If you are over heating the engine from over working it, I see a new clutch in your future regardless.

Well first off if you would have done some research you would have noticed the rincon is not a utility it is call a sport utility which means it is more of a trail machine with the capability to do some light utlilty work. It is not meant to work hard. I own a 650 and a 680 rincon along with 2 450 foremans. The foreman are geared for work but the rincons are geared for trail riding. They all are very reliable machines. Honda's ain't the fasted but the most reliable. The rincon is the best all around trail machine made. The 450 foremans are one of the best work horses honda made!

in this case I guess bigger isn't always better. The TRX300 Was one of the best utility style quads Honda built IMO if you want a good trail machine and a beast in the bad places I suggest the Grizzly. I know it's not a honda but they are from what I've read and seen an awesome machine. A few guys here have them and I'm sure they will agree.

I would have to agree with that.

The only problem I see with the grizzly is it is belt driven. Thats why I prefer the rincon over it. But it is a fact that the rincon is the best handling trail/utility atv avaliable. Most magazines even state that about the rincon and you can read all about it online. Now the grizzly has the belt drive which gives a lot more power which is fun and that have low range and a locker!

I think the belt on the Grizzly is what keeps a lot of people from buying the Grizzly, but I've owned 3 Grizzlys and I've never had a problem with the belt. The trick is to always buy the OEM Yamaha belt. If you buy the Dayco belt, it won't last long at all. The belt drive is the very reason why I chose the Grizzly over Honda. I wanted an automatic and I don't like any of the Honda auto trannys because I see too many people having problems with them and they are expensive to fix. If you do break a belt, it's cheap and only takes about 20 minutes to replace. I carry an extra belt with me and if it breaks, I can replace it on the trail in just a few minutes and be on my way.

The only belts that I've seen break are ones on 4-wheelers that have been sitting a long time without being ridden and have dry rotted or Dayco belts. I've seen Dayco belts break a couple days after they were put on.

If Hondas would have had the belt drive system like the Grizzly has and if they would have had the diff lock, then I would have probably chosen the Honda, even though the Honda has less horsepower.

If you take care of the tranny in the rincon it will outlast most. Go to RinconRiders.com and do a search on a guy called redrider on there. He has a EFI rincon with 16000 trouble free miles on it and had a carbed rincon with I do believe had more miles than that on it. There is another guy on there that has over 17000 miles on his rincon. Now that is a lot of trouble free miles on a bike. Its all in how you maintain your bike. When I go riding I take no extra parts because I don't need them! The last ride I took I watched a guy I know tring to ride over a small tree and the belt just started smoking like he was doing a burnout. Belts are just not for me.

He probably had a Dayco belt. LOL. I've never seen a Grizzly smoke a belt. I pull 4X4 trucks out all the time when they get stuck with mine and I've never slipped a belt. Some of the other brands don't have the belt system like the Grizzly has. The Grizzly has a centrifugal clutch on the end of the crank, so at idle the sheaves are holding constant pressure against the belt. This eliminates any slippage when taking off. A lot of other brands don't have that centrifugal clutch and the belt slips a little every time they take off, so the belt don't last long on those brands.

I've never needed any spare parts on the trail, either, but I carry a spare belt with me just in case.

I guess that's why the make different kinds, but I would have to say the Rincon tranny is an improvement over the Rubicon tranny.

No the guy wasn't on a grizzly that smoked the belt it was a polaris. I really like the looks of the suzuki 700+ atv's. Do they have a bad belt setup on them?

Yeah the old rubicons had tranny issues. The rincons use a automotive style tranny with a torqueconverter but the only thing I don't like about it is it won't hold itself back going over a steep grade. The new rubicons trannys must be better than the old because I hear all the time people wish the rincon had the rubys tranny for the low range!
