Dont waste your money on getting a bore on its last legs ported.

Get a good pipe and jet to suit, a +4 timing advance will give you some more low down power, well not power but it will move it to come on earlier on the pipe.

If you dont do deep water, remove the air box lid, but you must increase the main jet by 2 sizes, plug chopping to confirm.

Premixing at 25:1 rather than 32:1 will give you a little more, but then again you must increase the main by 1 size the compensate for the diminished fuel in the mix, again you must plug chop.

X-2 on porting worn out cyl. Best bet right now would be DIY porting. See sticky in engine section. Raise ex about 1mm (3/64") widen a touch, blend corners and champher it well. You have a perfect cyl to experiment with.

Is it full exhaust or just silencer?

reeds and no lid better exhause only other thing is to split the cases and put in a +3 crank for 400 or more. but you clearly dont want that so I wouldent sudjest it untill it breaks down. hope that helped

I ride dunes too. When I took off my lid I bought a outer wares cover and to mesh and made a lid to keep big chunks out of the box.
