I recently had a 690 raptor built that is performing very well in drag races but in an effort to get the most out of my motor in terms of horsepower and torque i am wanting to have it professionally tuned on a good dyno so if anyone has had this done with good results in oregon i would appreciate hearing about it.

 

there doesn't seem to be many, gary at tvi will have one in about 2 months.

 

Thanks bill.I am very pleased with the build i had done but i also know that i could probably get even more out of this motor if it was properly tuned on a dyno by a qualified mechanic.Chuck at CG does a very good build but he doesnt have a dyno and probably doesnt have the time to spend tuning every motor that he builds.I have been beating some pretty fast quads at florence that i couldnt even compete with before.It seems that some banshee riders get very offended when they get beat by a four stroke but i think with the new four strokes that we already have and what is to come they should get used to it.I am finding that my raptor performs much better on the south jetty hill than on the shorter comp hill because it really starts to shine when i hit third and open it up.I will probably still go with a nitrous system but if i do i am pretty sure that i will want better brakes because as it is right now i am having to really watch out on the top of the hills for other riders where as before i had more time and less speed so it wasnt that much of a problem.Maybe it would be a good business to start a shop around here that does dyno tuning because so far i cant find anyone that dyno tunes atvs.Any ideas on what the cost of dyno time at TVI will be when it gets going and do you know if he will tune or just give dyno runs?I will be starting my salmon fishing this weekend but if you are going to florence any time soon let me know because i would like you to ride my raptor now to see what you think as compared to what it was before.

 

think chuck build the baja 730 the i rode at florence, it made 65 hp with the dyno they got it to 72 or 73. that was some good power.

 

DTR in Salem has a dyno. Matt is a pretty easy person to talk with. Dont know what he charges though

 

Bill i think Chuck did build that baja 730 and he said it was very fast.Speedbump thanks for the information and i will give them a call.

 

it was very fast, and it just got back from kentucy with almost 10 more hp, got a new carb cams and pipe. chuck did a good job it was a great duner.
