Would it possible starting with gearing and clutching to upgrade my vmax 500 to a 700 motor? And still maintain riding ability through the process or would it be a summer process? I feel like my sled is extremely underpowered and i would like the added fuel efficiency of a triple

Found this thread in the "working log" section. Dont know if theres any major differance from 97 to your sled but the 500 twin to 600 tripple applys as crank/rods/cases are the same from 6 to 7 in the red head triple.

also...
here is a pic under my cowl... ill take a better one tomorrow, i was told the sled was liquid cooled but when i went to do basic maintenance after purchase couldnt find a coolant resevoir or fan... does that mean its forced air cooled?

Differance between red head tripples 600/700 is the top end and carbs. Upper/ lower crank cases, crank,rods,recoil,waterpump..etcall the same. Your sled is liquid cooled, in your pic you can see the radiator cap/hose. Not all sleds have a resevoir or fan. Your sled doesnt have a radiator though. Coolant is cooled via the heat exchangers running under the running boards. Your track slings ice/snow/slush as well as air moving acrossed them will cool them as well.

Read threw that link I posted. He went alot more with the
than your question was but covers the basics. If this sounds like something you want to tackle I would do just as he did. Find a 600/700 red head sled (sx/sxr/vmax) that has ben wrecked body/tunnel wise. COnsidering all the parts you will need would break the bank buying them all individually.

your coolant resivoir is right next to the oil tank. It has the little cover with the hose comming off it just venting to air.

So is it normal that the "coolant" resevoir level goes up when i add my 2 stroke oil?

Huh? Oil goes in the bigger of 2 covers that screws on the reservior, the smaller cap that just pops off, is the coolant. There should be no way for that to do that, unless you're adding oil to the wrong one.

i know where oil goes, both resevoirs were low, filled the oil first and the level in the second smaller one came up... it looked dark through the resevoir...is there maybe a cross that could happen between the fluids inline or at the engine (blown seals etc.) my uncles old car had issues with having oil wind up in the coolant and coolant resevoir

maybe i should just run the sled off a cliff and stsrt over... since a simple overhaul question has now lead me to believe my sled has multiple issues

Pull the reservior off and check all the hose connections. And make sure there are no holes between the 2. The oil tank should have one nipple connected to a line to your oil pump. The coolant should have one line connected to the coolant pressure cap on the main coolant hose. other than that the oil has a breather line at the top that runs some where along the frame, it might run up to the handlbars but it is just a vent line and ends with nothing. It makes no sense that the coolant goes up when you fill the oil tank, the two systems are not connected at all, except that they are molded together. It should be easy to trace to lines and see what's what.

I am pretty sure theres no coolant res on this sled, If theres was would it not have 2 caps? Look at the radistor cap and follow the hoses..........

It's there. Right below the oil cap, it's partially covered by the wiring harness.

If I am
let me apologize right now fellas. What I see is they "other half" of the oil tank. If I could figure it out I would post pics. Feel free to go to port yamha. Yamaha fische, 2001 vmax 500 dlx. Radiator hose shows complete cooling system. Take a look at the fische for oil tank........

But that is where the coolant reservoir is. It's the smaller tank on the oil tank. The "oil" tank is really 2 tanks molded together. The smaller one is the coolant tank and that line should run to the pressurized cap. The larger one is for oil and should only run to the oil pump. Any other way is wrong for this sled. I had the same set up on my 700 triple until I replaced it with the Viper set-up.

This is from your memory or fische? Did you miss the 500 TWIN part? NOT a red head tripple. Before you post again I am wrong please look at fische for 2001 vmax 500....got this guy talking about driving his sled off a cliff!

Look at the fiche again. My memory and the fiche agree. The smaller side is the coolant overflow tank, nothing to do with the oil except that they are molded together.

Your fische and my fische must be differant. Oil tank clearly shows lines from smaller side of tank to oil pump. Looking at "radiator hose" shows entire cooling system with no resevoir.
