Just wondering what anyone does with the 650 v2 when they travel to different altitudes. Do you have to adjust every time you change heights?

Does anyone have any information?

 

Well that all depends on how much of a change in altitude your talking about.
what is good about a 4 stroke vs. a 2 stroke and they can and will usualy run from fractory and all altitudes. they might not run the best but they will run good enough. where a 2 stroke well... if you jet it for say 7000 ft and take it to sea level then it'll run GREAT for about 5 min. then it'll blow up. 2 strokes all ways run the best right befor they blow up.
so if your just changing like say a few thousand feet then i'dd leave it alone. unless your racing that is, then you want it the best you can get...
anyhow hope this helps.

Thanks HR. I did hear that from a few others, but was not 100% positive. I appreciate your time.

 

I just installed a Dial-A-Jet, which should take care of any altitude, and weather problems

 

V2rider has it right, if you are worried about it buy the Dial-a-jet. Then jet changes are a twist of the wrist and you don't need to tear down the carb. I live at sea level but ride to as high as 7000 feet and yes the thing still runs, but not at peak performance. I will be installing the dial-a-jets on both quads before spring.

 

Hey v2rider. Where did you locate a dial a jet and what is the brand?

Thanks

 

Dial-a-jet

 

I have to deal with the altitude issues - a lot - because I ride at 7,500' and above. Las Vegas is about 2,000 feet and I assume you ride in the mountains around L.V. and perhaps Utah and so on. Those mtns are 5-6,000 feet, 7,000' tops. Assuming you've got it dialed in for 2,000 feet, you really don't need to do anything for an increase in altitude of 1-4,000'. Your bike will run fine. Not perfect, but fine for those rides. It will run a bit rich, but if you only spend aperiodic times riding at those altitudes I wouldn't mess with it. Now that said, to get it pretty close for a variety of altitudes the dial-a-jet is an excellent solution.

In Bear's case he rides at lot at sea level and high altitudes too so a dial-a-jet is an excellent choice. If your rides are mainly at L.V. altitudes with only once-in-awhile forays to the high country, don't mess with it. Remember, your power will be down ~3%/1,000' of altitude anyway so you'll be down on power regardless.

You might run over to Dynojet and talk to their techs. They are headquarterd in L.V. and give you some serious advice (remember tho, they are in business to sell stuff).

 

Thanks for the great advice Jimja. I appreciate that. I did not know that dynojet is located here. Small world. Yeah, I joined a club here in LV and I think they only go to the higher elevations occasionally. I think average is around 3500'. So you are saying that it should be ok, with a little sluggish acceleration. I can deal with that. Do you know if an upgraded CDI helps with the elevation changes? I read that it advances the timing a little for the lower speeds for more horse power.

You will get an improvement with the dial-a-jet, and you dont have to rejet your V2. If you talk on Acticchat at all, the V2 owners will tell you the same. Its the luck of the draw with a V2! I have the dial-a-jet, with my stock 122 jets, (which may be a factor in not having to rejet) a k&n filter, and its snorkled. It has more power now than ever! On the cdi question, the Dynatek cdi, or Copperhead which is alot more money, will give you a power increase through the entire powerband. A moose module, or simiar module, gives you a low end power boost only. If your going to get one, go right for the dynatek right away, or you will wish you did later.
