Hey I live in Ohio and am planning to go to ride in Colorado. Does any one have any ideas on what Jet Kit to install. I've jetted a 2 stroke Jet Ski before but I'm a little neverous about my baby. It is plenty animal for a weekend warrior like me and I DON'T want to F it up. Some of the trails we plan on ridding are 10,000 FT. ANY HELP?????

 

Welcome to the forum sorry I cannot help you much w/ you question but if you have any questions about riding in our wonderful and fun filled state I'd be happy to help.

 

We haven't decide exactly were yet, It's not until June... Any recomendations?

 

How's that 700r run at altitude is there a EFI setting you changed. I keep wondering if there is a kit to turn my 660 into an EFI machine. It would probably be better than chasing jetting/seizing my babies engine... LOL

 

As far recommendations for where to go that depends on what you want to ride. We have everything from mud riding to trail riding, rides that have some of the best views in the country. If you are famillar with downhill skiing and the way the rate terrain green, blue, black this is the same way we rate our atv trails green being easyiest black being extreem it all depends on what you want to do! As far as you quad you might want to check out raptorforum.com and they will help you setup your quad. For rules and where to go I can give you some good reccomondations but you can also check out staythetrail.org for some pretty basic mapped trails. I bought the 700 for two basic reasons first efi and the 700r repution of beeing what I consider to be a leggend in atving allong the lines of a honda 250r but for trail bikes!!!!!!!!!!!! If you have any more Questions just let me know.

 

Incase anyone out there reads this.... A Denver Yamaha dealer advised me to re-jet @ 5% of stock to go from base in Colorado to 11,000 ft. given that it's a percentage it may work for other 4strokers. Not sure what % it would be IF the jets were not stock which I assume to be 140(L) and 145(R). I may post again to with varification. If any one has contradictory info PLEASE let me know I don't want to F up my BABY.
