ok Ive come to the conclusion im going to purchase an 01 XC SP but i have a problem. Which motor the 600 VES or 700 BB. I want lots of low end power and torque and it must be SNAPPY. I plan on moding the engines but which is a better base to start with. If i get the 700 its getting SLP single pipe but no one makes a good single for the 600 VES. What do you guys think?

I would go with the 600VES because even with the engine stock it will keep up with the 700's. It has excellent tourque and acceleration. But might give you a bit more hassel to mod if you use to something eles. But it's pretty basic. I believe SLP make a good silencer for the 600 VES engine. I't reduces 8#s of weight. And gives you a little bit more horsepower gain. With some well placed tuning that sled will roll with the 8's and 900's.

ok, if i doo the 600 ves, i was thinking HPS silencer or an MBRP race, SLP heads, v-force reeds, boost bottle, Team roller, and im not sure yet about the primary, possibly a heel clicker setup. Then off coarse it would be regeared. Im also thinking of the struthers 660 kit but thats pricy.


As for the 700, basiclly the same mods but use the SLP single

why wouldlnt get the slp twins for the 600 . there a better buy for the buck , plus they give you better gains all round

Your set up sounds good. I wasn't aware that there was a twin pipe for it. But you should look into that. Like RAD RACER said, it would be better gains all around. What type of v-force reeds are you planning on getting? The 660 kit is a bit of a waste of the bucks. With the money you spend on a kit like that ,you could do more mods and deck the sled out better than what the kit would do. Thats just my opinion though. The SLP heads are a good choice, they have a better peak horsepower than any others I have heard of. For the primary clutch I think would go with the EPI trail performance clutch kit. The heel-clicker is a good approach aswell. I'm not to sure of what other kits run for but the EPI's run around $150. I'm thinking about ordering one myself for my XCR 600. Do you know of any other good clutch kits for an XCR 600? Anyway I gotta be goin (school tomorrow)-- sigh.... So tell me how this is workin out for ya.

I'd say definately get the 600 VES. Much better power throughout the whole powerband!
I had a 01 XC SP 600. I had a CHubby single pipe, dynoport can, v-Force II reeds, 1.25 lug camoplast track,and a clutch kit.
Mine was fast, but I just took out my 04 MXZX 600 SDI for the first ride. My SDI motor isn't broke in, but this sled is wayyyyyy faster than my XC was modded. I know mine is now 3 years newer, but I just want to make it clear that a 01 will take some MAJOR mods to get it to run with the Newer sleds. The SDI is unreal. Its dead even with the 01 MXZX 800's!

But anyway, I would definately get the 600 VES, its a very nice engine with gobs of power and a huge potential! I loved my 2001! :)

Deadman- when you installed the hot seat single, where did it make its power? low end, mid range or top end? did it increase torque? hot seat wont give me a dyno sheet and i want to know where the power increase is. How bout throtal responce?

Guess I'm having a little trouble understanding why anyone would be interested in buying a sled with a motor sized in a manner that they knew they were going to have to mod it to get what they were really looking for in the first place. WHY NOT BUY A SLED WITH THE BIGGEST MOTOR YOU CAN AFFORD TO START WITH? It will be much less expensive in the long run.

Why would you consider modding a 600 when you could buy a 700 or much better yet an 800? For the 10lbs difference? That's crazy. Which motor do you think will get better gas milage, a twin piped, ported 600, or a factory stock 800? Which one will last longer, be more reliable? Which one would potentially make more power when all is said and done? There is still no substitute for cubic inches. Never will be.

Best bang for your buck is big blocks when it comes to modifying. Small blocks are twicked to their limit from the factory. I have seen small blocks decrease in HP when pipe was added.

Those 600 ves motors are wicked. I have one and it is impressive and all stock.
Nothing like the torque from a big block though. Think about what you like in a motor. Do you like the way a 350 winds up and the higher pitch sound or do you like the grunt of a 454? Sometimes I don't know which one I prefer betwee my 600 and 800. Both are impressive in their own right.

the reson i want either a 600 or 700 is because your can use there power band on tight trails. Right now i have an indy 400 (89 and tweeked to the max) and i can put up better times around tight trails then i can on my friends 600 (98, mbrp can). Now the rider doesnt change only the sled, and literly, on 1.2 mile trail (tight and twisted) im consistently 13-18 seconds faster on my sled. Now that might not sound like much but streach that trail out and thats a big difference.

If I were you, I would look for a 2001-1/2 700 VES. Get the heads cut and reshaped, porting, SLP single, SLP airbox mods and clutch it. Total cost would be approx. $1,200. and you will be eating Firecats(stock) for lunch. Don't waste your money on a can, get the whole exhaust. I would not get another 700 with Kehin carbs(pre 2001-1/2). You will spend more time fiddling with them than riding. Good luck!

I HAVE A 98 XC700 WITH SLP TWINS AND SLP HEADS, BOTTLE, REEDS AND THAT SLED WALKS BIG TIME.STAY WITH THE 700 FOR INSURANCE REASONS AND MOD IT

horsepower-how is the throtal responce one your sled? Im looking at that same combinatiuon but w/ the single pipe. Then i plan on lightening the sled up big time.

Instead of putting your cash into mods for an 01, just go but an 02, 700. Get the power valves, 130 hp. You'll have the fastest sled, be the top womenizer, outdrink the buddies, coolest garage, etc.

i would like to get an 02 but 01 is streaching my budget. i was origionally going to build a 98-99 but i want the edge chassis for jumps.

since your planning to modify, get a 700 ves, piped and clutched, these are wicked sleds, and anything you do to it will give you greater gains,for less money, than a 600,slp,hot seat, they all do extensive testing on their products used on the 7's, not much out there for the 6's.Personally I've got an 01.5 700 xcsp, slp pipe and can, team secondary, geared down 1, and today I put on a camoplast 1.25 ripsaw, and I zip tie stock 8's everytime, plus I pay ins. on a 700, as the saying goes "there's no replacement for displacement" ,stick w/ a big block 7, and ves,you wont be disappointed :)

Sorry there Indy,I didnt see your last post, If your strapped for cash,I'd go w/ a 6, their quick, and make good power, but I am a little confused, i thought you said you were going to mod this sled? :( Oh well,good luck ! SWRules

UNCLEBUCK- i have set aside separate money for the purchase of the sled, and my planed mods. The newer the sled i get, the less mods i can do. In a perfect world, i would get an 02-03 pro-x 440, and put the stuthers 660 kit in it.

You said you want lots of low end power and torque and it must be SNAPPY. They may not actually be faster but a well tuned 700 (which was easier to find in the 2001s) IMO definetly feels torquier and faster.

In Jan 2001 I bought a hold over new 2000 700 xcsp. A guy I ride with looked at one from the same place but decided he wanted the edge and had been told the 600 VESs were as fast or faster. He bought one. On the trail we seemed pretty close. On some straight-aways I was WOT and we stayed side by side but we never really raced. We then switched sleds. At the next bar I heard him telling his brother "man, I can't believe how much faster that 700 is than my 600". I had just been thinking that his 600 felt weaker than I was expecting (it was the first VES I'd ridden). Now, I'm not saying my sled IS faster but it sure felt like it.

A well tuned 700 will give you that arm pulling feel even if in a drag race the 600 VES will keep up and sometimes win. The 2001s were a lot better with the Mikuni Flatside carbs rather than the Keihn D slides so they should almost always be a touch faster than the 600s maybe not worth the price difference new, but used the difference will be minor if at all.

Just my opinion.

I have a 2000 xc sp 700 non ves and my friend that i do a lot of riding with has a 2001 xc 600 ves From a stand still he is always first but as i put some distance on the lake i always pass him over 60 mph and this was before the v force reeds the clutch kit and slp single thats going on the machine with boost bottle (CANT WAIT TO TRY IT OUT THIS WEEKEND) i WOULD GO FOR THE 700 OR 800S .I dont know if you do a lot of riding over 60 mph but if you do go bigger its like an overdrive with the bigger engines. Oh ya two of my friend seem to like the ride of the gen2 better than their edge machines same with me ! If you decide on a 600 go with a 2000 in the gen 11 it will blow other newer machines away in the twisties and the 2000 has the 600 ves engine as well or go for the edge X model they handle much better than the plain edge. Good Luck ! :D

Oh ya studs will help as well !
