You can see what I have done to my Tonka truck so far.


What else would someone recommend for low to mid power ?

I am not looking to change anything internal.

Tell me ... tell me or i will do it!


Tell me or I will do ...I promise I will sell it and by a Craptor

 

Try alcohol...you will love it

 

What are the risk with Alki?

Are there any mods required to run on Alki?

Tell me more ... I like it.

If you can't smoke them then smoke it!

Only so many ways to get more low end. Higher compression works, watch out for detonation though. Bigger bore/stroke should help too. Dual plenum manifolds are a great way to build low end and consequently sacrifice some top end. A roots type supercharger will give you a torque monster but along with the dual plenum manifold doesnt apply here since they don't make one for a DS650 or any quad that I know of.

Lower gearing will help you feel like you have more low end because of the torque multiplication.

More midrange hit can be accomplished with the right cams and port job.

 

Low end can be enhanced with a supertrapp disk system, with slight effect on top end. Modify your end cap to fit 4" supertrap disks and put on 18 or less. I played with many combinations on my RWR pipe, 18 disks matched jetting of open end nozzle and had little effect on top end, but fewer disks helped more with the low end with some top end suffer.
The difference is noticable but don't expect too much - the DS already has killer low end if the carbs tuned right anyway. I run a open end Yoshi now, and I could notice the slight loss of bottom from switching from the disk set-up, but it was minimal enough for me to not worry about it.

Oh, and Tonkas are for kids, DS's are for grownups.

 

I highly recomend droping to a 15th front sprocket at least. Not that much and if you dont like it you can always sell it but I think you will. Makes the DS pull much harder and still has awesome top end.

 

ohh and if you want torque that will pull your arms out of your sockets, try NOS.

 

I also reccomend alky, i heard its awesome.
