WOW!! 45 Pilot Jet and 95 Main Jet did you put on a BBK? Also Running at those high rpms your motor will not last, that is 2 stroke territory not good for a 4 stroke.

Agree with ya Alley. Its a wonder it even runs with those big jets in there. My trike is a 72cc, when I used a carb it was a 19mm with a #35 pilot jet and a #85 main jet. It would cruise at 42mph 6800 rpm on level road. Every thing else stock except 6gram sliders. 7200-7500 is the peak horse power range for these engines. Your engine wont last long if its turning 9 grand at 40 mph. When I got it it had a #29 pilot and a#80 main and would hit 40+ at around 7500.

Yes Roy, I didn't want to say anything but a 45 pilot jet No even the 250s come with a 45 pilot jet and the 150s come with a #35. Got it setup wrong and can get to 40 with a lot less RPMS if setup right.

Here is an update. The trike has been bumped to 99 (100)cc and a new carburetor was installed because the power curve would never settle down. I had to put the original barrel into the variator so the belt would stop flying off and being destroyed! The trike will now reach 50 MPH, provided no heavy wind resistance. The weights are 10g, which seems to given the optimum torque, while no longer
flying the belt to destruction. Since buying this unit, we moved closer to Alabama and bought a dune buggy. No need for this Q6 beast anymore. Contact me if you would be interested in buying this souped up monster. Over $2500 invested, but will part with for $1500 or good offer. It has been
serviced by reputable mechanic in the Pace Florida area. He increased the displacement and installed a high quality carburetor as well.

This unit also has a rear storage compartment that can fit two full size helmets.

Contact me if interested.

I have found no problem with finding the tires, but wouldn't you need 10X6 wheels to mount these
tires, since the current wheels are designed for 50s?  I have been looking everywhere and have not
been able to find wheels that have the 4/110 bolt pattern.  There are plenty of tire/wheel combinations
for trailers, but all are 4X4 bolt pattern.

The trike now will do better than 50 MPH at about 7400 RPM.  I bought new trailer wheels, (10X6)
new tires (65), and two adapters from Adapter Kings to convert from 110mm to 4" to support the
new wheels.  I changed the M11 bolts on the hub to 7/16" and used 1.5" grade 5 bolts and steel
hex nuts to cinch the adapter and tightened to 100 ft pounds.  Bought 12X1.5 lug nuts to bolt the
new wheels to the adapter studs.  The only thing remaining is to adapt the rear fenders to fit over
the new wheels/tires.  Still working on that problem.

Based on another reply to this original posting, I purchased ST205/65-10 tires. Further research
indicated that size is not recommended for 8 inch wheel width.  If I had purchased ST225/65-10 or 
ST235/65-10 tires, I could have used the existing wheels, instead of the process above.  The wheels
and adapter set up is able to handle 1100+ pounds per wheel and speeds well over 80 MPH.  If the
stock wheels can handle 50+ MPH safely, the tires would be the only required change when using
the larger 225/235 mentioned above.  I went to Goodyear to mount the new tires to the new wheels,
and they did it for no charge!  I tipped the service guy. 

This site was helpful in determining the suitability of the tires: mostwheels.com/rimwidth.html ...
The included information stated the ideal size wheel for a given tire/wheel size is the middle of the
range of acceptable sizes.

That is all for now. These updates allow me to not have to be at full throttle to reach 45 MPH. Now
I have to back off the throttle to keep from speeding!

AH, The trike has been bumped to 99 (100)cc.

Now we know why the bigger jets But I still question the #45 pilot jet not even a 250cc motor comes with a #45 size pilot and 150s come with #35's jet. Maybe its a #35 that I would buy since the stock carbs for 50s come with 30-32 pilots.
With the #45 I would sure like to hear it rev up and as well as under load, I would expect it to be sluggish or have some bog or hesitation due to, to much fuel.

When the carburetor was changed the jets were included. I have not opened it or
checked with the service guy to see what he put in there, but the power curve is
now smooth. Thanks for reminding me he still has the jets from my old carburetor.

I now have the fenders back on, so the conversion project is completed. Still
interested in selling this beast, FYI.

Anyone interested in seeing this beast or making an offer, it will be available by Tuesday
at Dirt Cheap Fun in Pace Florida. Mike (the owner) will be making a few adjustments and
then selling it for me.

Now I have to decide my next hobby project...
